CBD Oil Side Effects: What to Know Before You Try CBD Oil

Reviewed by Lisa Blohm, PhD, MSN, RN


CBD oil and its many benefits have been taking over much of our communication lately. We’ll admit, we’re pretty excited at the many medical conditions that can be helped from just this one supplement.

When we’re able to help our customers find their healthy place, we’re in our happy place.

And we’ll also admit, we’re a little blown away by how safe and effective CBD oil is — and how many of our customers all across the USA are reporting incredible results.

But nothing in life is perfect, right?

In this article, we’re going to explore some of the side effects of CBD oil, whether or not it’s possible to take too much, and what CBD oil can make you feel like. We’ll look at some scientific research and discuss testimonies and reports from CBD oil users.

Let’s jump in!

CBD oil side effects

CBD oil side effects are minor. It is considered to be a ‘safe substance’. Pure CBD oil without THC cannot make you high.

In fact, it’s worth noting that even whole cannabis, or marijuana, is also actually considered to be an extremely safe drug. It’s virtually impossible for an adult human to ingest a fatal dose — although you can definitely make yourself feel extremely sick from using too much of it.

Reported side effects from studies and anecdotal reports from consumers affirm that CBD is a ridiculously safe supplement with very few side effects. But all of our bodies react differently to substances, right?

Here’s a full list of CBD oil side effects that have been reported or documented (according to current research and studies).

  1. Dry mouth. CBD oil can cause dry mouth. While researchers aren’t completely sure why this can happen, a study published in 2006 showed that the endocannabinoid system receptors CB1 and CB2 are present in the glands responsible for producing saliva. When these receptors are activated, the saliva production can drop, leading to dry mouth. Dry mouth is exactly what it sounds like, and will pretty much do nothing more than prompt you to drink a little more water than normal.
  2. Lower blood pressure. High doses of CBD oil can cause a small drop in blood pressure in some individuals. This will usually occur within a few minutes of the CBD oil entering your system. This doesn’t happen to everyone, and the worst you should expect is a few minutes of feeling lightheaded. However, if you have any problems with low or high blood pressure, or are taking any medications for blood pressure, talk to your doctor before trying CBD oil, because this may not be a good fit for you.
  3. Lightheadedness or dizziness. This is usually connected to low blood pressure, as mentioned in the point above, but some people just feel a little dizzy for a few moments after CBD oil hits their system. This typically passes within a few minutes on its own, or can usually be resolved by laying down for a few moments, drinking a cup of coffee or tea, or snacking on a little piece of chocolate.
  4. Nausea. Some people have found that ingesting CBD oil can cause mild stomach discomfort. This is based off of reports we’ve heard and read, rather than any evidence from scientific studies. This is an odd side effect, considering that CBD oil is used to help relieve nausea and increase appetite. If nausea does occur, it is mild and typically goes away quickly. If you find this happens to you, decrease your dose and it should go away.
  5. Sleepiness or drowsiness. This side effect of CBD oil should hardly come as a surprise, as high doses of CBD oil may be used as a sleep aid for those struggling with insomnia. At low doses, CBD oil causes relaxation and diminished pain or anxiety — both conditions that can contribute to insomnia. At higher doses, it can produce drowsiness. If CBD oil causes drowsiness for you, don’t take CBD oil before operating machinery or driving a vehicle. Remember, CBD oil can sometimes take several hours to kick in.
  6. Increased tremors in parkinson’s disease. If you suffer from Parkinson’s Disease, we recommend speaking to your doctor before trying CBD oil. Early research suggests that one of the side effects of CBD oil, when taken in high doses, is that is may worsen the muscle tremors associated with Parkinson’s Disease. More recent research has indicated that at low doses it may also be safe and helpful for those struggling with this disease. But, because there is some ambiguity on this topic, we strongly suggest consulting your medical practitioner before trying anything.
  7. Headaches. Can CBD oil cause headaches? Yes, and no. CBD oil is used to treat headaches and migraines, and there are hundreds (if not thousands) of people who report that it effectively relieved their pain symptoms. It’s more likely that if you’re experiencing headaches as a side effect of CBD, that the product you’ve purchased is a lower quality CBD, or contains solvents, such as ethanol and isopropanol, which some people are sensitive too. We’d recommend switching to a higher-quality hemp-based CBD oil, and the headache problems should go away. That said, we’ll also admit that all of our bodies are a little bit different, and it may just be that CBD oil isn’t your best fit.

Although medical research on CBD oil and medical marijuana use is still in the beginning stages, thanks to Federal regulatory laws, researchers have devoted some serious effort (and even put their own careers at risk) to prove that CBD oil is not only safe for human consumption but actually a huge benefit.

Can I overdose on CBD oil?

Consistent consumption of CBD oil over long periods of time has, so far, showed no health concerns. A study in 2006 reported,

“…Acute CBD administration by the oral, inhalatory or intravenous route did not induce any significant toxic effect in humans. In addition, chronic administration of CBD for 30 days to healthy volunteers, at daily doses ranging from 10 to 400 mg, failed to induce any significant alteration in neurological, psychiatric or clinical exams. Finally, in patients suffering from Huntington’s disease, daily doses of CBD (700 mg) for 6 weeks did not induce any toxicity.”

A later study also showed that chronic use and high doses up to 1,500 mg/day of CBD were well tolerated. This study examined the side effects of CBD oil when consumed daily for a month. It showed that all patients and volunteers tolerated CBD oil very well, and showed no signs of toxicity or adverse side effects.

The conclusion of these studies is that, based on results from animal and human research, clinical data indicates that CBD oil can be safely used over a wide dose range, and over long periods of use. There are no CBD oil withdrawal symptoms, as the system does not become chemically dependent on CBD.

So — our conclusion? When using CBD oil based on use recommendations and reasonable dosages, you don’t need to worry about overdoses or toxicity.*

Can CBD get you high?

This is one of the questions we hear most often from curious customers — can CBD oil get you high?

Easy, simple answer. No!

CBD oil does contain trace amounts of tetrahydrocannabinol (THC), which is the component found in cannabis that is responsible for creating the ‘high’. However, these levels are 33 times lower than necessary to produce a high. CBD chemically cannot get you high.

We will note that it is important to find a high-quality, pure CBD oil that is hemp-based or appropriately processed. Poor quality CBD oils may contain enough THC to produce an effect. This is easily avoided by choosing quality brands.

What does CBD oil feel like?

Honestly, it mostly feels like nothing at all — unless you happen to experience CBD oil side effects.

Depending on the reason that you’re taking CBD oil, you may feel any of the following:

  • Increased sense of calm or diminished anxiety
  • Improved mood
  • Reduced pain and diminished discomfort related to inflammation
  • A sense of relaxation, sometimes with a mild ‘loosening’ of the muscles
  • Sleepiness or drowsiness

Basically, the primary way that you’ll ‘feel’ CBD oil is through the relief of the symptoms that you’re taking CBD oil for.

What drugs should not be taken with CBD oil?

Side effects can include some CBD oil drug interactions — specifically, the inhibition of hepatic drug metabolism and decreased activity of p-glycoprotein. In layman’s terms, CBD oil can inhibit the activity of some liver enzymes that are responsible for metabolizing pharmaceutical drugs. High doses of CBD oil can temporarily neutralize these liver enzymes, which affects the way the drugs are used in your body.

To put this into some perspective, eating a grapefruit would have a similar effect.

If you are currently taking any pharmaceutical drugs, we’d suggest speaking to your pharmacist or primary care doctor to discuss any possible complications before taking CBD oil.

How to choose the best CBD oil

Purity, in any supplement, matters more than anything else. In order to see the actual benefits of CBD oil, you must find a great CBD oil product. We’ve done some intense screening on the CBD oil brands we’ve decided to include in our stores. 

You can purchase some of our favorites right here!

But there ARE a lot of inferior products out there as well. Here are the guidelines you need to follow when buying CBD oil online, rather than from a trusted local nutrition store, dispensary, or medical practitioner.

  1. Always check the purity. It should be more than 50% CBD, or more, with no or only trace amounts of THC.
  2. Always check the source. We’d recommend only buying CBD oil that has been manufactured in Canada, Europe, or the USA. Thanks to some strict regulations, this will help ensure a higher quality product.
  3. Don’t leap for the cheapest CBD oil. Just like everything in life, you’re going to have a pay a little more to get good quality — and it’s worth it. When it comes to your health, it pays to be choosy. Spending more on quality makes sense when spending more means actually seeing benefits.

If you have more questions about CBD oil side effects or CBD oil benefits, we’d love to talk to you further. Give our team of Wellness Consultants a call at 608.571.1094 or drop into any of our store locations.

  1. Nasadol on

    This is a great review. CBD has a therapeutic window in which it is most effective for people. Therapeutic ranges vary from person to person so it’s important to start with low doses.
    Side efects mentioned in this review are more likely encountered when people take higher doses of CBD. Variations can also result from bioavailability and route of administration. For instance, nasal administration results in much higher brain levels than transdermal, or oral applications of equivalent amounts, so less CBD is needed when taken nasally.

        Hi Lindsey,

        Sorry to hear that CBD didn’t prove to be the solution we were hoping for. Remember that our return policy guarantees products, so bring your bottle back into the store and we’ll give you full in-store credit. We’d be happy too, to help you keep looking for a solution. You are 100% right — CBD isn’t a miracle cure-all, and because we’re all different, CBD works great for many people, but not for everyone. Stop back in — we’re here to help!

      • Carrie on

        Me too! Mine is definitely pure and high quality and no solvents are used. Only MCT oil is used to pull the CBD out. It gives me a horrible headache. Thankful for this article giving me some answers though. Doesn’t help with my pain either. Just with my sleep. And is it possible that it’s preventing electrolyte absorption?

  2. vicki webb on

    I’m currently taking CBD oil that is full spectrum with natural cannabinoids and terpenes, produced from the c sativa bloom, the company assured me it’s good, I don’t know if I’m not taking g enough, I feel more relaxed, but alot of my pain still remains, please give me your feedback please.

    • Rynn Jacobson on

      Hi Vicki,

      We’d be happy to talk to you about your dosage to see if we can address that pain issue. Why don’t you give our Wellness Consultants and call and we can have a sit-down conversation with you to troubleshoot the issue. 608-663-2640 Look forward to hearing from you!

    • Rynn Jacobson on

      Hi Mandy,

      That’s an unusual response for CBD, but we are all different! It may be that changing the brand could be helpful, or we may want to change your dosage further. Why don’t you stop by the store or give us a call to connect with one of our Wellness Consultants? We’d be delighted to help you figure out the best solution. Here’s our contact info!


    • Suezbull on

      Mandy, I believe your results are not all that unsual, but not very popular right now as people are looking for answers they couldnt find elsewhere and hope. Unfortuately i have given it to my anxious dog twice now and a year apart sold by two different companies. The second being a more reputable and a higher quality organic company. Both times my dog became increasingly MORE agressive to other dogs. I had to stop. I dont see anyone else put there who have had similar results. I think people should be made awhere (as you said) everyone is different and will not be guaranteed the same results.

  3. RW on

    I was taking THC and CBD oil for pain and developed stomach pain so bad that I thought I had pancreatitis. It was the worst pain of my life and lastest about an hour. I had previous stomach discomfort from the oil but this last bout has kept me from ever wanting to try it again. I can’t vape or smoke because I about choke to death and edibles aren’t legal in our state so I’m off of the marijuana and back to opioids unfortunately. I did have gastric bypass surgery 10 years ago – I suppose its possible it make me more sensitive.

  4. Jorge Delgado on

    Can CBD cause exesive night sweating? I have give some drops to my Mom (91 yrs old) and notice she needs to be changed many times at night as she sweats a lot. I had not noticed this before taking the drops.

    • Rynn Jacobson on

      Hi Jorge,

      Great question. We’ve never encountered anyone developing night sweats from CBD oil. In fact, some people use it to help diminish symptoms of menopause, including hot flashes. However, that being said, we are all different. We’d recommend adjusting the dose or stopping temporarily to see if that affects her night sweats. Why don’t you give our Wellness Consultants a call — we’d be happy to talk it through with you! 608-663-2640

  5. Rynn Jacobson on

    Hi Cynthia,
    Great question! We would recommend that your father consults with a licensed medical professional regarding this. CBD is not a blood thinner, but it can interact with medications and affect blood pressure, etc. Definitely check with your health care provider!

    • Rynn Jacobson on

      Hi Pat,

      Great question! CBD can cause nausea for some individuals, particularly when they’re taking high doses. It’s odd, as CBD is also used to help people struggling with nausea and low appetite. We’re all a little different, so the responses vary too. If you’re experiencing nausea, consider taking it with food or backing down on the dose. If you want to chat with someone on our team, feel free to call us at any point or swing by one of the stores. We’re here to help!

  6. Lindsay N Pevny on

    Ooh, this is helpful! I use CBD oil for my dogs, to help them with reactivity. It’s tough not knowing how they are feeling because they can’t tell me if they are experiencing side effects, but we do get it from a source that grows their own hemp plants, and it’s organic. We haven’t been using it for very long, but I do notice a calming effect about 30 minutes after they take it. I’m going to make sure they have something to drink afterwards like broth or goat’s milk to combat dry mouth.

    • Rynn Jacobson on

      Hi Lindsay,

      That’s awesome! Glad to hear you’ve found a good option for your pups. I use it for mine and it works really well for chilling out our more hyper furry family member. If you run into any questions, just reach out. We’re here to help!

        • Rynn Jacobson on

          If CBD is taken sublingually, it will absorb rapidly in the bloodstream and not be metabolized through the liver. Not sure if it’s a concern with medication interference for you, however. By using CBD sublingual the risk of interference is much lower because it is not going through “first pass-effect”. If it’s a higher volume of CBD taken in a single dose, there may be some issues, if you are swallowing most of the CBD. Typically, it’s not a huge concern, but definitely connect with your doctor if you have medical conditions or are taking medications that CBD may affect. You can also use our LiveChat feature to connect with one of our Wellness Consultants if you have additional questions too — we’re happy to help!

      Hi Risemarie,

    • Rynn Jacobson on

      Hi Vidya,

      I’m so sorry that you’re going through this. To answer your question, not feeling a ‘reaction’ to CBD is the most common response. The results build up over time.

      Because you’re in the midst of a serious health issue, I’d urge you to have a one-one conversation with our Wellness Consultants so that we can make sure we’re making recommendations and giving input that is accurate and helpful for your situation. If you reach out to us, we’d be happy to work with you and your medical doctor to step alongside you in this however we can. https://apple-wellness.com/contact/

  9. Steven Botha on

    The first time I came across CBD was when I was visiting my brother in San Antonio, Texas 2 years back. The one day I had some serious back pain, My brother’s neighbour suggested that I should try CBD oil for my pain as it helps his mom with her cancer pain, and directed me to a local CBD shop in San Antonio where I bought a 2000mg CBD oil. In the beginning, I was a sceptic, but it worked so well that I ordered three more bottles to last me for a few months. I must say that also felt relaxed but could do my work with no issues as it didn’t make me high. To date, I’m still using CBD oil for my pain and came off pain medications completely.

  10. Paul Turner on

    I started to take CBD after I had a hard time sleeping due to bursitis in the shoulder. My trips to physical therapy only aggravated the pain issues from inflammation. My doctor and PT prescribed ibuprofen but when I used their prescribed dosage, it caused me more gastric problems than normal. Since using CBD sublingual at 5 drops of 300 mg at night, it seemed to help me get through the night and I stopped completely the use of over the counter pain relievers. An added unexpected benefit of daily nightly CBD use, was that my Gerd symptoms (that I had for years) disappeared and allowed me to stop taking Prilosec daily. For pain during the day, I use CBD as needed. I think CBD is a great natural alternative to pills. All in all, I am very pleased with CBD and expect to continue to use it moving forward. I am 68 years old and I believe that CBD for me at my age is a great thing!.

  11. P on

    So I got an ignite CBD disposable vape pen and I just took my first hit and the sides of my head in the front like both of my temples feel really weird and it’s a very uncomfortable feeling like I’m kinda freaking out. Idk if it’s bad or not but there are also some essential oils in the vape also. Please help quick. I wanna know if I’m okay and if this is normal and if it will go away.

    • Rynn Jacobson on

      Hi P,

      That is definitely a very unusual response to CBD — it sounds like maybe you’re reacting to one of the ingredients in the pen. It’s possible that you’re sensitive to CBD, but it could be the pen and quality of ingredients in that. I would urge you to stop taking CBD immediately. Why don’t you give us a call when you’ve got a free moment and talk through your experience with one of our Wellness Consultants? They’ll be able to provide some additional guidance after chatting with you.

  12. Julisa on

    I smoked before bed and feel asleep but when I woke up it felt like I was dizzy going to pass out with no oxygen to my brain and I had a tingling sensation in my head is that normal ?? Can CBd increase ur anxiety ?

    • Rynn Jacobson on

      Hi Julisa,

      That would be a very unusual response. CBD can make you feel dizzy, but this is usually very brief and promptly after taking it. It’s also possible that you’re using a contaminated CBD brand. With the recent boom in popularity, there are quite a few poor quality products circulating out there.

      It sounds like you’re smoking CBD buds, not using softgels, drops, or vapes such as those we sell in our stores. Is that right? Why don’t you give our Wellness Consultants a call and we can talk through what you’ve been using and if there’s another option that can have less unpleasant results for you. https://apple-wellness.com/contact/

    My mom is taking a CBD oil and recently changed brands. The current brand is supposed to be a “gold” one, and it is burning under her tongue and her throat when she takes it. Any idea why??

    • Kate Davison on

      Hi Amy,

      I don’t know why your mother would be having a reaction like this to the CBD product she switched to but she should stop using it immediately!

      If you or your mother would like to call one of our stores a Wellness Consultant would be happy to talk you about other options. If you purchased your product from us you can return it for an in-store credit or we can help you find a different CBD product.

    • Rynn Jacobson on

      Hey Tammy! Great question. CBD can affect how drugs affect our bodies, but most of our customers who use CBD for depression have only reported positive results. That said, it’s always best to check with a pharmacist or your primary before starting, stopping, or altering your medication use. Call our team if you’ve got any more questions — we’re happy to help!

  15. Lori on

    Hi. I stumbled upon this website because I’ve heard numerous times that cbd or possibly marijuana use could potentially help me with several of my problems. I’m an absolute mess all the time and I can’t take most medications for numerous different reasons. I want to start by saying that I’ve never used any recreational drugs and barely can coax myself to even take my prescribed medications due to serious phobias. My family is full of addicts and I was always afraid to be one of them.

    My list of problems are as follows:
    C-PTSD and all the symptoms that come with it (due to several severe and reoccurring traumas throughout my life – MANY triggers)
    Severe Generalized Anxiety
    Major Depressive Disorder
    Severe Emetophobia (severely irrational fear of nausea and vomiting)
    Fear of vehicles
    Fear of travel
    Fear of illness
    Fear of medications/drugs obviously
    Severe motion sickness issues
    Sleep problems

    Severe back pain
    Severe neck pain
    Severe overall pain (pretty much symptoms of fibromyalgia without a diagnosis of such)
    Irritable Bowel Syndrome

    Due to my other issues, I’m extremely out of shape even though I’m not much overweight. I can’t even walk for 10 minutes without causing myself considerable pain. I do everything I can to avoid traveling in vehicles and only do so if it’s less than a 15 minute ride because it’s all my anxiety and other issues can manage. I’m only 39 and I feel like I’m not even a living person anymore and I’m sick of it. I’m desperate for a solution and mental health therapy, physical therapy, various prescriptions that have come and gone over the years have not given me much help at all. My body doesn’t react well to pharmaceutical pain relievers. I’ve been given many prescriptions over the years that I’ve stopped because they just didn’t work and they gave me weird reactions. None of those reactions were “serious” reactions, but they made me anxious and freaked me out. I’ve been prescribed several different medications over the years for my stomach issues and various nausea related issues (including Protonix, Zantac, Prevacid and Prilosec for my GERD issues, and Phenergan, Zofran and an anti-motion sickness patch I can’t remember the name of.) And I’m sick of being sick… I’m sick of taking so much nausea medication that makes me sleepy. I’m sick of being afraid of everything.

    I’ve spoken with my doctor and he’s said that it CDB has a slight chance of working for me but that he wouldn’t recommend marijuana itself. He recommended that if I go the CDB route, I use it topically as to not upset my already angry-all-the-time digestive system. It’s all legal here; I live in Oregon. I don’t know what to do. I’m so afraid to even try it. I have no way to quickly get to a hospital if I start to freak out or anything. I’m all alone and no one can even provide a ride in that situation to get me to one and I’d hate to call an ambulance in the event of an already terrifying situation, not to mention how hard vehicle rides are for me at all even when I have no other cause making it worse. I know that most people don’t ever have any type of serious effect from any level of anything cbd or even thc related, but the one time I was given demerol when I was in labor was an absolutely terrifying nightmare for me… at least I was already in a hospital and supervised. No one is going to hospitalize me so that I can use cbd oil… I just don’t know what to do. I need a solution, I want my life back.

    I know this was a huge post… like I said, I’m an absolute mess. I’m not suicidal, but I swear I don’t know why I’m still fighting to stay in a life that doesn’t seem to want me and I know I have GOT to do something!! If anyone, someone can read this and give me honest, real feedback about a suggestion (keep in mind, I’ve spoken to my doctor. I’ve had years of therapy and I’m STILL this much of a mess) I would really appreciate it. I need to know how to be prepared if I want to try this as my last resort. I have no idea what I’d even buy! I know nothing about CBD or hemp or marijuana or THC (except that THC is the thing that gets you high). I don’t even have anyone in real life I can ask about any of this other than my doctor who pretty much just tried to be very statistical about it. if you actually read this, thank you from my whole heart… thank you.

      Hi Lori,

      I am so sorry that you have so much on your plate. Even just one of those health conditions would be a lot to deal with.

      Because you have such an extensive number of health issues, I really don’t feel that we can confidently recommend anything to you without further information. I’d recommend that you have a one-one chat with one of our Wellness Consultants so we can go into more depth with you about things you’ve tried and what might be a viable option. If that sounds like something you’d be interested in, give our team a call at 608-663-2640. We’re here to help!

    • Rynn Jacobson on

      Hi Treasha – We’d recommend backing down on the dose you’re taking. Changing the type of CBD oil you’re taking too may also help. Some people respond better to an isolate vs full-spectrum, etc. If you stop in the store, bring your open bottle and we can chat with you about how much you’re taking and when, or get your current CBD exchanged for a different brand. Finding the right fit the first time around can sometimes be tricky, but that’s why we have our product guarantee in place! Stop by or give us a call – we’re here to help!

  16. Darlene Collette on

    I’ve had been taking the hempworx CBS oil for about 5wks and just recently stop because of some side effects……dry mouth, rapid heart rate, slight headaches, night sweats, diarrhea and always feeling exhausted…..
    So will see if all of this is caused from the oil!!!!

    • Rynn Jacobson on

      Hi Darlene — Wow! So sorry to hear that you’re experiencing all of this! There are a few things that could trigger reactions like that. First, low-quality CBD products can be diluted or contaminated with other ingredients. With the recent boom and availability, many shady businesses have begun producing poor quality CBD extracts. Secondly, depending on what you’re taking, you could be allergic to something in the ingredient list — coconut oil, for example. Third, you may be taking too high of a dose and need to radically back down. Some people are more sensitive to drugs, supplements, foods, etc., than others. Finally, it could be that you’re having a reaction to the CBD oil itself. We’re all a little different and what works great for some can be a poor choice for others.

      If you’ve got any more questions on this, know that we’re here to help our customers in any way we can. Give us a call or drop by one of our store locations and we can help you find something else that actually works for you.

    • Vickie Cosgrove on

      Wait Darline!! Don’t give up just yet!! I was having some of the same problem’s and discovered it was the coconut oil they use as a carrier oil!!! I have gut problem’s and just quit omeprazole which really messes you but up BAD!!! Hopefully it will go away but, in the mean time I refuse to give up my CBD!!! I switched to capsules!! They take a little longer but, just as affective!!! Good Luck!!!

  17. Denise Evans on

    What is considered a high dose? It’s been mentioned several times in this article and I was curious.
    Thank you,
    Denise Evans

    • Rynn Jacobson on

      That’s an excellent question, Denise! The answer is two-fold. Generally, a ‘high’ dose would be anything significantly above the recommended doses on the products themselves. However, it’s also important to remember that all of our bodies are a bit different. For those who are more sensitive to CBD, a daily dose may be half the recommended dose for them to see amazing results. When it comes to dosing, just remember that it’s okay to play around and find what works best for your body. If you ever run into any questions, feel free to call us. We’re here to help! 608-663-2640

    I started getting headaches as well but as my body got use to the oil the headaches left. Also some companies use grapeseed oil and that gives me a headache as well.

      Hi Lona – Yes, CBD can be helpful for diabetes and there have been reports that it has proved helpful for sleep apnea as well. Because you have so many health issues going on, however, we’d recommend having a one-one chat with one of our Wellness Consultants. Give us a call and we can get that scheduled! 608-663-2640

    I have used CBD edibles, lotion, water & syrup. It can certainly cause your head to feel strange in high doses. In small doses it is highly therapeutic in larger does this is what I experienced… increased anxiety, strange feelings in the head, sweating, clamy & very unattached. It was scary but know that nothing bad can happen. The effects unfortunately at high doses can last for hours. It was almost 6 hours of strange discomfort. I thought I would end up in the hospital. I realized it was similar to taking too much THC & the results are you over react to whatever the symptoms are as they are perceived as exaggerated.
    At small doses it is highly therapeutic & calms you down, takes away pain, relaxes you & can help you sleep. I also noticed I had very good dreams while on it.
    If you experience any bad reactions know that this is harmless & always feels much more intensified & that you are fine. It will pass & you will be completely back to normal. Don’t panic just distract yourself & this will help you. I talked on the phone & places myself around other people so I wouldn’t be alone.

    I wanted this to work, I really did. I have trouble sleeping and did not want to have to take pharmaceuticals. I tried three different brands of CBD. (btw, I have been no stranger to pot in my life). The first two times I took a small amount, but yet the next day I felt like I had a hangover. Okay, maybe another brand/make would do the trick? The third time I tried it (my fault, and I accept that) the retailer assured me that this would “change my life forever” and that I was on the road to a new calm. Trust me, I wanted to believe, I just wanted to sleep. My ‘inner voice’ was saying you are smarter than this snake oil, but I delved in anyway. I am not saying that this will be your outcome, but for me I thought that I was going to die. I was violently ill for two days and frankly, was too embarrassed to go to the hospital. If you feel that sick do not be stupid like me, go to the ER!!!! My experience was like having a hangover, but only times a thousand. Please, if you want to try this, try it slowly, really slowly. I know that it works beautifully for some people, and that is great. I am just saying proceed carefully. Be safe, be informed, be loved, be well, Love, a fellow human.

      Hi Sally,

      Your comment is a great reminder for everyone in regard to several things! First, it’s vital to source CBD from a trusted, reputable company that is committed purity and ingredient integrity. With the recent boom in CBD supplements, lots of shady businesses have jumped in with poorly made products, some of which are made using dangerous additives. When we hear about violent reactions to CBD like those you described, it’s almost always due to a poor quality product.

      However, since it sounds like you went through several brands, I’d say it sounds like you may have a sensitivity, if not an allergy, to CBD. While a reaction so violent is very uncommon, it’s important to remember that we are all made differently. We have different sensitivities, different thresholds, different metabolism. What works for some (or even most) won’t work for everyone. Your advice is on point – go slowly and listen to your body! Thanks for sharing your story in our community!

    I seem to be developing breathing issues since taking a low dose CBD hemp oil. PureScience 400. Heaviness in chest, hard to breath and catch a deep breath. Nasal stuffiness and head pressure. Back of throat feels like it’s swollen and almost restricting breath. Was taking it at night for restless legs anxiety have MS and it was helping me and I was getting peaceful sleep until these appeared. Had been taking it for about 2 months. Any info. On hemp allergies?

    • Rynn Jacobson on

      Hi Rose,
      Wow! Those are unusual side effects. I’d recommend that you stop taking that CBD product immediately if you haven’t already done so. It may be that you’re allergic to something in the oil (coconut oil, etc) or possibly hemp. I’ll have one of our Wellness Consultants reach out to you to explore alternative brands and types, such as switching to an isolate, etc. Let’s figure it out!

  23. Maggie on

    I have 2 dog’s one with tumors and was nearly lame with legs crossing in the back as and tremendous amount of pain…CBD is a miracle for him no contest
    Now little Reako younger and anxious is resistant to even eating it in pntbutter but I insist bc of the preventive health..
    I’m noticing Reako feels like he’s losing weight and his muscle tone seems depleted… I’m worried… He was well… Two yrs ago I lost my baby cat to feline Mets breast cancer and she felt the same way..
    I am starting to question my sanity here.. Could this be making my healthy dog lose weight and muscle?

    • Rynn Jacobson on

      Hi Maggie,

      Great question! Glad to hear your older pup is improving! As for Reako, that would be an unusual response to CBD oil. First, if you haven’t already, I’d suggest taking him into the vet to have him checked out, just to be sure there’s nothing more serious going on.

      It could be that he’s sensitive or allergic to something in the extract (example, coconut oil, olive oil, etc) or hemp. A BIG concern would be having you make sure that you’re purchasing a CBD that is meant for dogs, or a CBD isolate. Dogs are sensitive to THC, so it’s important to be careful you’re not using a CBD extract meant for humans.

      Assuming Reako has an all-clear from the vet, try taking him off of CBD for a time to see if that resolves some of the issues. Dogs are like people — some of us have reactions to things that are super helpful for others! At any rate, trust your pet-mom instincts! Those pups are lucky to have you.

      Let us know if you have any more questions or need help in any way. We’re here for you!

  24. Marva Hardage on

    I’ve been using CBD oil for about a week and a half for Fibromyalgia symptoms. I’ve noticed since starting to use it that I have increased cramps in my legs, especially the back of my legs, all the way up. Not Charlie horse type cramps. It feels like my muscles are just knotting up. Could the CBD oil be causing this?

    • Rynn Jacobson on

      Hi Marva,

      Great question! It’s possible that this could be related to the CBD, though it’s not a side effect that we’ve heard of before. We’d suggest lowering your dose for a while to see if the symptoms improve. If so, it may be that you should try a different brand or type of CBD extract. We’d be happy to chat further with you about this if you want to give us a call at 608-663-2640.

      Let’s get you feeling better!

  25. Jon Fea on

    Highest quality available but it is really giving me stomach nausea, diarrhea just plain awful.
    Last bottle was full spectrum and first two ( bottles) months were not and this might be the issue.
    It may/can cause side effects, regardless of what you read. It did me and I am off of it!

    • Rynn Jacobson on

      Hi Jon,

      Thanks for sharing! Yes, it’s important to know that anything can cause side effects. We’re all a little different, so while most respond very positively to CBD extracts, it is still possible to have a negative response too. It sounds like perhaps a switch to an alternative type of CBD extract, such as isolate vs full spectrum may be helpful. If you have any questions, know that we’re only a phone call away (608-663-2640) and we’re happy to help you find alternatives.


    • Rynn Jacobson on

      Hi Ebele,

      Great question! The answer is that it depends! There are two primary types of CBD oil, isolate and full spectrum. Generally, we’d recommend full spectrum as this offers a good blend of terpenes as well as cannabidiol+. However, isolate is a better option for those who want a product with not even trace amounts of THC (in case of a drug test for their employment).

      The bigger issues will always be 1) choosing a high-quality product and 2) finding a reputable brand. Then, we can begin discussing your specific needs and goals to see what options would be best for you. I’d encourage you to give us a call or stop in the store to chat with one of our Wellness Consultants. We’re here to help!

  26. Jarvis Mitcham on

    Thanks for the great post. I have a question I hope you can help me with… I was wondering, what are the main causes of headaches? I have a headache for the past 3 days and it just won’t go away. I appreciate any help you can provide.

    • Rynn Jacobson on

      Hi Jarvis,

      There can be many causes for chronic headaches, from allergies to misalignments, to stress and much more. I’d suggest that you see a chiropractor or medical doctor. CBD is an excellent aid and supplement, but it isn’t a replacement for professional medical advice when that is necessary! If there’s anything we can do to help you out, never hesitate to give us a call or stop by one of our store locations. Hope you feel better soon!

    I decided to try and take this to see if it would decrease head and neck pain from a accident six years prior which I was diagnosis’s with sever post concussion . I took 1 ml as bottle stated and should have only took a few drops. Three hours later all of a sudden I Felt like my eyes where bugging out and like I was in a trance unable to move smoothly . Felt like I had jerky movements with my throat feeling like it was going numb with burning mouth and throat . I raced to the hospital because I felt like something not right . . Half of my head went numb and throat was terrible dry . Chest was burning with half my body feeling hot then it went cold . I felt like I was going to quit breathing . I had taken 1 ml as the bottle said but should have started with a drop . Beware and be careful do not take this by yourself as you may need someone to drive you to the Emergency department .

    • Rynn Jacobson on

      Hi Ava,

      Great question. Yes, any side effects you develop due to CBD extracts would resolve after you stop taking the oil. If you’re experiencing muscle tremors, I’d suggest that you stop taking CBD oil and consider consulting with one of our Wellness Consultants regarding brand/potency. Quality is an important factor.

      If you’d like to chat, we’re here to help!

      Hi John,

      Great question! I’m going to have one of our Wellness Consultants reach out to you to chat about this. You’ll hear from us soon!

    Hi i have gastitis i started taking cbd oil and it made me calm and helps with pain but i started getting a pain in my chest and shoulders and a little bit of arm so of course that scared me but my heart rate was great but im wondering if it didnt agree with my stomach so it gave me chest pain

    • Rynn Jacobson on

      Hi Sara,

      I’m so glad to hear that CBD is helping reduce pain and anxiety for you! In regard to the pain in your chest and shoulders, we’d have a few more questions for you on that. How long does this discomfort last? Is there numbness or dizziness that accompanies? It may be that switching to a different type of CBD extract could be helpful, or we may want to tweak your dosage. I’d encourage you to give our team a call at 608-663-2640 or swing by one of our store locations to have a one-one with one of our Wellness Consultants so we can chat with you further.

  29. Priscilla on

    I have recently started taking cbd gummies and notice after about 5 minutes i get chest discomfort for about 10 minutes then it goes away and my body feels really relaxed is this normal

    • Rynn Jacobson on

      Hi Priscilla,

      Great question! Brief episodes of tightness in the chest and dizziness after taking CBD is not uncommon. If this becomes excessively uncomfortable or begins to last longer than a few minutes, we’d suggest that you lower your dose or call into our team to talk through what’s going on.

  30. Naya on

    I had cbd two weeks ago and developed severe dry throat, difficulty swallowing and breathing.
    I stopped taking it then and the symptoms have not gone away.

    • Rynn Jacobson on

      Hi Naya,

      Thanks for taking the time to leave us this feedback. Dry mouth is not an uncommon side effect of CBD oil, but difficulty swallowing and breathing would indicate that you may have an allergy. However, because the symptoms are lingering, we’d suggest seeing your doctor, as an allergic reaction to any substance would not last for longer than a few hours to a few days at most. If there’s anything we can do to help, or if your doctor would want to call us to chat through any questions regarding CBD oil, know that we’re happy to do so.

  31. John on

    I have issues with Gerd. Started taking CBD oil and immediately had issues with indigestion. Due to medications I take already take I wanted to find something that you can take long-term with no side effects to control the Indigestion due to Gerd. I found that Beano can be taken with no long-term effects. I now eat two Beano pills before putting the CBD oil under my tongue in the morning. I’ve had absolutely no issues with indigestion since. I started taking CBD oil due to pain in my hands from arthritis and it is helping but something I never anticipated was how we are now into spring and with pollen I usually have a lot of migraine headaches. I’ve had no migraines since I started this CBD oil. Still in experimental mode so don’t know if this will last all spring but for those of us who get migraines, if we can get rid of them before they start that alone is worth it. Beano can be purchased at any supermarket or drugstore.

  32. Bluejay on

    Love, love Cbd. Only problem is I became allergic to it. Developed rashes on feet and legs. As soon as I stopped Cbd oil it went away. But now I have ordered one without mint flavor and hope it works as well as last one did.

    • Rynn Jacobson on

      Hi Bluejay,

      We’re so sorry to hear you developed an allergy! It’s possible switching to a different type of CBD oil, such as an isolate, could be helpful. If that new one you purchased has the same result, give us a call and we can chat with you about other options. We’re here to help!

  33. Sharon on

    I’ve been taking CBD Oil for about 2 months and it isn’t turning out well. I’ve had all of the side effects mentioned in this article except I’ve had severe insomnia. Weird dreams when I do sleep, but insomnia mostly. Which makes it difficult to function the next day. Along with my torn up stomach, sweating, stomach cramp diarrhea. This is not good. I went back down to one drop under my tongue with no relief from these side effects. I hate the ideas of giving up on CBD Oil. I had such high Hope’s of getting away from big pharma drugs. 🙁

    • Rynn Jacobson on

      Hi Sharon,

      We would encourage you to stop taking your CBD right away. It may be that you’re allergic to one of the other ingredients in CBD, so we could try switching you to a different type (such as an isolate). But it’s possible that it’s just not right for your body. That’s okay, we’re all different! We’d be happy to talk with you about other CBD options, as well as other supplement options too. Give us a call or stop by one of our stores and we can have a one-one chat with you about it. Let’s get you away from those pharma drugs!

  34. Amy Paige on

    Some companies are selling fake CBD, make sure you don’t fall for their trap. Upset stomach, diarrhea, and gastrointestinal distress are not typically caused by cannabinoid oil itself, but rather by ingredients used to deliver CBD oil into the body or flaws during production. Without those factors, CBD may even help treat stomach issues.

    • Rynn Jacobson on

      Hi Amy,
      You’re absolutely right. With the boom in CBD interest, there are a lot of CBD companies that are selling extremely poor quality products. Before we bring any new product line into our store, we thoroughly test them for quality, purity, and integrity. So important to choose premium quality!

  35. Echo on

    I used beeZbee’s sour disel tincture, hoping it would help my joint pain, but it would only touch the muscles (although, it did work amazingly for muscle pain, that’s not my highest concern). I switched to the Gelato today, as it has “Pain relief” as one of it’s effects, but I’m pretty sure it’s what given my my first tension headache ever. I took it and my head started hurting about 15 minutes after. Took it again (to relieve my headache) and it got much worse after 15 mins again.
    Can different terpenes give different side effects? Because I’ve never experienced this with other CBD products.

    • @rynn on

      Hi there,

      Thank you so much for the great question!

      When it comes to both hemp and even marijuana “profile/strain” differences, (which include both cannabinoid and terpene differences) most folks respond differently to the changing blends.
      For example, here in Wisconsin we can only deal with CBD/ Hemp-based products. There are still huge differences when it comes to the profile of each product. Some have higher CBD vs. other cannabinoids, while others have lower CBD content with higher other cannabinoids within the profile. Same thing goes for terpene amounts and variations.

      I say this because response always depends on the body. Some people get slightly different reactions (good or bad) if a profile is high in a particular compound their body simply does/doesn’t work well with. This comes to play in both hemp and marijuana products.

      I would say your body must be sensitive to a particular terpene or cannabinoid that is much higher in Gelato vs beeZbee’s.
      It is extremely hard to say for certain, but play with dosing and profile differences per product.

    I started taking CBD oil on a Thursday evening, was in the bathroom most of Friday. Stomach ache all day Saturday and more bathroom issues, by Sunday morning I was bloated, nauseated and more frequent bathroom trips. I did not take Sunday evening dose. But it is not Wednesday and I still have bloating, nausea, stomach aches and more bathroom trips than normal. How long before these symptoms subside. I do have a slower digestive tract. I have increased my fluid intake and added gatorade to hopefully flush this out of me.

    • Rynn Jacobson on

      Happy Monday, I hope your week is off to a smiling and sunny start.

      I’m sorry to hear about your unbalance within your digestive tract! We help clients digest issues like this almost every day. It is a bit unusual that CBD, even after just a few doses, would do this to the digestive tract.
      You might be sensitive to the carrier oil within the product itself. Usually, this is MCT oil (healthy fats for coconut oil) or hemp seed oil (also healthy fats from the hemp plant itself).

      If this is the case, you are on the right track for resetting the gut. Lots of water, minerals, and sleep!
      If you need an extra hand with detoxing, we have a few awesome recommendations as well!

      Also, there are many different profiles of CBD for your support — hopefully, one of which won’t affect you so intensely! Let us know if you have any other questions on your goals and we can recommend a far better fit for your success. Click the LiveChat button on our site in the bottom right hand corner and one of our Wellness Consultants can help you out in no time.

  37. Samantha on

    I have Narcolepsy, and decided to try a CBD/THC oil. I have never had any good experiences with THC in the past, due to the psychoactive affect it always had on me. Therefore I’ve always avoided it due to it causing everything from mild paranoia to horrifying hallucinations.
    However, in an effort to try to find a more natural solution to taking strong and addictive sleep medication, I recently began taking an average 18:1 ratio (18 parts CBD, 1 part THC). Or a beverage with a 4mg CBD, 2mg THC. INever more than 4mg at the most of THC at any time. It was working well for me! I recently cut out the THC for a short period while looking for a new job, and switched solely to CBD oil only. After a few days of that, I began experiencing severe stomach pain, it first felt like severe menstrual cramps and then morphed into feeling like I was punched in the gut, then proceeded to experience everything from cramping to bloating, gas, diarrhea, sharp and burning intestinal pain etc.
    I switched brands, which helped for a few days, but the pain has returned. I’m miserable and horribly uncomfortable in the mornings and then again in the early afternoon, lasting the rest of the day.
    I’m confused as to whether this is a result of the CBD oil itself, or is from stopping it? Either way, I haven’t had much nausea, only severe stomach and lower back pain.
    Do I stop it completely or continue to take it? I cannot seem find any balance with either option?

    • Ross Maly on

      Hi Samantha, thanks for reaching out! That sounds pretty intense & I’m sorry you’re experiencing this. At this point I’d suggest refraining from any CBD/THC mixtures for at least 1 week to give your system a bit of a reset. There are many other supportive supplements when dealing with narcolepsy such as omega 3 fatty acids, a high quality multivitamin & especially vitamin D! If you’d like to try the CBD/THC again make sure you’re getting it from a high quality/trustable brand. Here is the one we’ve seen lots of great results with over the years – click here

      Please reach out if you have further questions! We want to do our best to support you and your health. Best wishes.
