Serious CBD Oil Side Effects Nobody Told You About

CBD Oil Side Effects

CBD oil — that magnificent, powerful phrase/product/cure that we have heard so much about. Everywhere you turn, there are praise and glory about its impact. However, rarely does one hear anything about the CBD oil side effects, even though they are extremely important.

The “bad boy” THC is to be partially blamed for this. The public has been focused on its effects for so long, even trying to ban cannabis entirely due to this psychoactive ingredient. That said, when CBD was discovered, people were inclined to believe cannabidiol is what makes cannabis such a powerful healer.

However, nothing is perfect, and neither is CBD. Contained in hemp oil or not, with or without some THC content, CBD oil comes with its fair share of downsides.

First, let’s take a quick look at what CBD is, and then you’ll find out everything there is to know about the negative side effects of CBD oil.

The Basics of CBD

What Is CBD?

CBD (cannabidiol) is just one of many cannabinoids in the cannabis plant. CBD structure remains absolutely the same whether we’re talking about CBD from hemp (Cannabis Sativa) or the ‘’regular cannabis” (Cannabis Indica).

There are over 100 cannabinoids within cannabis. These natural substances can bind to our own endocannabinoid system. This is why CBD is so efficient in the first place — our body recognizes it as a familiar substance. 

Luckily for us, CBD research suggests new incredible health benefits every day.

What Is CBD Oil?

To better understand the CBD oil benefits and its effects, let’s explain what the oil actually represents.

There are two types of CBD oil:

  • Pure CBD oil
  • Full-spectrum CBD oil

The first one is guaranteed to have nothing else but CBD and carrier oil (olive, avocado, hemp seed oil, coconut oil, etc.). The latter comprises CBD, THC, and all the other cannabinoids you can find in a cannabis plant. Terpenes come into the picture as well.

CBD oil can be taken in various ways — as the oil itself and as a CBD oil-infused product (CBD gummies, creams, lotions, patches, pills, and so on).

Less and More Common CBD Side Effects

Similarly to any medicine, CBD oil comes with a (long) list of warnings. And just like it is the case with any other drugs, the side effects may or may not exhibit themselves. Regardless of the reason, the fact remains that some people will endure the adverse effects. 

One of the biggest reasons for this is that we are all different and that our bodies react individually to a stimulant. In addition to this, there are some things we can influence to avoid the side effects of CBD and get the maximum of its good sides. 

Here are the most common disadvantages of CBD usage!


Whereas it is usually THC that is praised for a cannabis treatment for insomnia, CBD can make you drowsy as well. This is usually the case if you take a higher CBD dose than recommended. 

On the other hand, if you wish to avoid these CBD negative side effects, just take a smaller dose.


CBD is not cut out for a sensitive stomach or palate.

If you take CBD in the form of oil drops, you could feel sick. This is especially true if you take it on an empty stomach. The general rule of thumb applies here as well — take your medicine half an hour or an hour after a meal. Drink plenty of water afterward. 

Due to its application, the CBD cream side effects will include some other states, such as tiredness but hardly ever nausea.

Appetite Boost or Loss

Depending on what you’re trying to achieve, this could be great for you. CBD oil products are very much praised for increasing appetite, particularly in cancer patients. 

Moreover, CBD oil for anxiety and reduced anxiety levels usually encourage people to eat more. The appetite-boosting quality is mainly connected with full-spectrum CBD oil. 

Tingling and Numbness

CBD oil side effects include tingling on the lips or all over your body, especially if you’ve applied CBD oil topically. On the one hand, this is nothing to worry about and the sensation should disappear soon enough (within minutes). Many find it enjoyable, too, and it’s definitely one of the reasons people opt to try out CBD-infused lubes.

On the other hand, extreme or prolonged tingling sensation or numbness could be a sign you’ve exposed yourself to a higher dose of THC, so make sure you only buy CBD oil, flowers, etc. from reliable suppliers.

CBD Oil Side Effects on Eyes

Besides causing eye redness as one of the most common side effects, people with glaucoma should avoid using CBD products. Based on the American Academy of Ophthalmology report from 2019, CBD oil can worsen the symptoms of glaucoma.

Namely, the researchers found out that CBD can raise the eye’s pressure by 18% four hours after applying CBD drops. 

On the other hand, drops containing only THC can decrease the eye’s pressure by 30% within eight hours.

Since more research is needed on the subject, it’s not advisable to use CBD products to treat glaucoma.

Dry Mouth

Dry mouth is one of the second most common CBD oil side effects. Basically, it is the feeling as if someone filled your mouth with cotton balls. It usually occurs if you’re using oil drops. 

The scientific experiment behind it suggests that CBD inhibits the endocannabinoid receptors in our brain, which are responsible for saliva production.

Luckily, dry mouth is only temporary and easily solved — just take a big glass of water after consuming CBD oil.

Smoking CBD Oil Causes Sore Throat 

Smoking or vaping CBD oil can result in a sore throat and raspy voice. As you know, smoking blunts or CBD pre-rolls makes your mouth and throat dry because you inhale toxic chemicals together with the tar from the hot and dry air. 

The severity of the throat irritation will depend on the type of cannabis you vaped or smoked and your tolerance to smoke. 

On top of that, smoking CBD oil burns your throat, so if you want to avoid these problematic side effects, you should:

  • Stay hydrated
  • Avoid spicy foods
  • Gargle with warm salty water
  • Reduce the frequency of smoking/vaping

Other alternative methods that can help you with a sore throat include:

  • Avoiding energy drinks and caffeine
  • Licking lemon or honey
  • Drinking herb tea with fruits
  • Buying a vaporizer that will get rid of the stale, dry air in your home
  • Smoking outside of your home

CBD Vape Oil Side Effects

Vaping CBD oil can cause the following side effects:

  • Feeling drowsy 
  • Decreased appetite 
  • Diarrhea
  • Rash  
  • Fatigue, discomfort, lack of energy  
  • Insomnia

To avoid these side effects, make sure you’re vaping CBD correctly. First of all, avoid additives like diacetyl and vitamin E acetate. Next, buy your CBD from reliable brands, and lastly, determine the correct dosage.


Diarrhea is one of the side effects of CBD oil in humans as well as their pets. Here are the two main reasons why you could be experiencing this symptom:

  • As with any other medication, your body needs some time to adjust to it.
  • Since CBD oil alters your appetite, you may have changed your regular eating habits. Your gut gets revolted against the smaller or bigger food intake.

After one or two weeks, the symptoms should stop. Your body will adjust to CBD and the new eating pattern. If you are already suffering from diabetes or a similar appetite/weight loss condition, be very careful about maintaining your goal weight.

CBD Oil for Sleep Side Effects

On the one hand, CBD oil will help you fall asleep faster. On the other hand, you may experience very realistic dreams during the first couple of nights. Even nightmares.

What happens is that CBD allows you to enter a deep sleep stage called N3, delta sleep, or slow-wave sleep. Luckily, you should be free of bad dreams after two days or as much as it takes your brain to adjust to the new substance.

CBD Oil Side Effects on Kidneys

There are some opposite opinions on this one. According to one study, cannabis is beneficial for patients with advanced chronic kidney disease (CKD). It helps them regulate the pain and exhibits no side issues. 

Another research found that cannabis has an adverse effect, especially if it’s consumed via smoking. Patients were advised against medical marijuana, and CBD oil possibly could have the same effect. 

What are the side effects of CBD for healthy people? Apparently, none. Those who did not suffer from kidney disease did not show any reduction in kidney functions while using cannabis.


Dizziness due to CBD oil typically occurs if one takes a higher dose than they should. The easiest way for this to happen is during vaping. It takes some skill to master it because it isn’t the same as smoking a joint. 

Usually, people smoke concentrates rich in CBD, THC, and terpenes, so the “high” hits them rather unexpectedly.

To avoid side effects of vaping CBD, be moderate and careful about how you get your CBD vape oil. Dizziness could also be caused by low blood pressure.

Parkinson’s Disease

Various studies have reported a link between cannabinoids and Parkinson’s, yet, we still don’t have enough evidence that shows it can be used as a potential treatment. 

Parkinson’s patients are advised against using it if it interacts with some other medications because it can cause mood changes, diarrhea, and tiredness.

Keep in mind that if you use a too high dosage, it could even worsen the symptoms of the disease. 

Grapefruit and CBD Oil Side Effects

Grapefruit and similar fruits contain certain substances that interact with CYP450 enzymes. In short, it prevents them from doing their job of dealing with the drugs we take. 

If the enzymes are unable to do their part of breaking down the drugs in our bodies, the drug will end up in our liver, from where it will go into our bloodstream unprocessed. This means that you could end up with more drugs in your system than you are entitled to.

What about CBD tincture side effects? CBD behaves similarly, plus it interferes with more enzymes (CYP3A4 and CYP2D6) and increases the drug level even more. 

Even after you quit using CBD oil, your body won’t be able to use the drug normally until a few days have passed.

In this respect, the side effects will also show if a person is taking antidepressants, antihistamines, benzodiazepines, and statins.

To prevent the triggers in this case, be wary of the grapefruit warning on medications. Otherwise, CBD will turn the low dose of your medicine into a high dose.

CBD Oil Side Effects on Liver

This topic is pretty much intriguing, as it made some headlines.

Most articles that are against CBD oil usage rely on a mice study. Having been exposed to high CBD doses, they developed hepatotoxicity. 

However, what is usually omitted from catchy headlines is the fact that CBD was given in high doses. For example, the doses equaled what would be three and ten times bigger doses than the recommended one for Epidiolex. 

Essentially, Epidiolex is pure CBD oil. It does come with a label warning about CBD hemp oil side effects, saying it should be used with caution if one is taking liver meds. Still, taking a dosage three times bigger is worrying no matter which medicine we are talking about.

To sum up, side effects are possible, but they will occur only with extremely high doses if your liver is healthy.

Headaches and Migraines

When buying CBD oil of some kind, these CBD oil side effects may be listed on the label. In reality, the chances of CBD provoking headaches are very low.

According to one study, CBD does not cause headaches or migraines. On the contrary, it is recommended as a cure

The cause of headaches may have more to do with any substances or solvents added to the oil. Given that not all CBD brands are reliable, sometimes a simple change of CBD brand will end the pain.

Reverse Tolerance

With CBD, you never know. Your body may develop tolerance to CBD effects after some time. This usually happens if your CBD oil contains THC. 

In contrast, CBD is also known to cause reverse tolerance. This means you will need a smaller dose after using CBD for a long time. 

To be safe, monitor your doses and reactions.

Low Blood Pressure

The reason for lowering blood pressure could be that CBD may act as a blood thinner. If you’re already on blood-thinning meds, the side effects of CBD oil can become very dangerous. 

For example, even though CBD helps post-surgical pain and recovery, you shouldn’t be taking it one week before the operation.

CBD dilates blood vessels and is an excellent aid in preventing thrombosis or the formation of blood clots. But if you’re already using blood thinners, always consult with your doctor before you start experimenting with CBD.

CBD Oil Side Effects on Heart Palpitations

CBD could potentially help people with arrhythmia due to its anti-inflammatory properties, and many studies confirm this statement.

What’s more, CBD doesn’t have serious side effects when it comes to heart palpitations. However, its interaction with other arrhythmia medications can be potentially dangerous. 

For example, CBD can interact with warfarin, nitrates, certain statins, beta-blockers, and calcium channel blockers. Therefore, it’s essential to consult with your doctor before trying anything on your own.

What Are the Side Effects of CBD Oil If You Are Allergic?

A cannabis allergy is a real thing. It manifests similarly to any other pollen allergy — runny nose, sneezing, rash, or itchy skin. 

The allergy may be provoked by airborne allergens, handling the plant (people working in the industry are especially at risk), or even by eating some delicious edibles. Truth be told, CBD gummies’ side effects usually come as the consequence of overdosing on them, which is even more worrying if you are allergic to CBD.

While you could have a mild allergy to cannabis, it could make other allergies stronger, particularly food allergies.

If you are taking CBD oil for the first time, beware of these CBD oil side effects — dry cough, itchy eyes, sore throat, dry skin, blisters, hives, or watery eyes. Should you experience any of these, you may be having an allergic reaction to CBD oil.

CBD Oil Interactions with Other Drugs

Admittedly, the list is quite lengthy. We already mentioned some precautions when we discussed blood thinners and liver meds. Here is what to pay special attention to if you’re using CBD with other drugs. 

It will interact with the following, so we strongly advise you against using CBD with:

  • Clobazam (Onfi), and
  • Valproate.

CBD may interact with:

  • Zonisamide
  • Topiramate (Topamax)
  • Sedative medications (CNS depressants), such as Nembutal, Luminal, Seconal, Duragesic, Sublimaze, morphine, Diprivan, Pentothal, and others.
  • Rufinamide (Banzel).

Side effects of CBD hemp oil can also manifest if you use:

  • Medications that increase/decrease the breakdown of other drugs by the liver:

Tagamet, Luvox, Prilosec, Ticlid, Topamax, Tegretol, Dilantin, Mycobutin, etc.

  • Medications that decrease the breakdown of other drugs in the liver, such as:

Cordarone, Fortovase, Invirase, E-Mycin, Erythrocin, Cardizem, etc.

  • Medications changed by the liver

Endometrin, Prometrium, Adalat CC, Procardia XL, Sandimmune, Xanax, Norvasc, Biaxin, Sandimmune, erythromycin, Mevacor, Nizoral, Sporanox, Allegra, Halcion, Calan, Isoptin, and many others.

  • Eslicarbazepine (Aptiom).

Does CBD Oil Have Side Effects in Pregnancy?

Short answer — nobody knows. The American College of Obstetricians and Gynecologists (ACOG) advises pregnant women against using cannabis in all its forms, CBD oil included. 

So far, research on CBD oil dangers during pregnancy hasn’t been conducted. The existing studies all relied on cases when mothers-to-be were regular cannabis consumers. 

They showed that smoking weed or eating cannabis during pregnancy is dangerous for the baby and may even cause stillbirth. 

However, there is no evidence whatsoever that the use of CBD oil could cause the same consequences.  

More Dangers of Using CBD Oil

This section has nothing to do with how your body processes CBD but rather with the side effects of CBD. To be more precise, it deals with whether or not you got what you paid for. 

Namely, CBD oil regulations are far from picture-perfect. Unless you are buying from a reliable source, you may experience some hardships.

Here are a couple of reasons which may repel you from consuming cannabidiol.

  • FDA — CBD oil is not FDA regulated. It isn’t even listed as an FDA-approved dietary supplement. Why? Most probably, because cannabis is still listed as a Schedule 1 drug. Hence, it’s a bit challenging to do the paperwork for something similar to heroin (which belongs to Schedule 1 too).
  • Harmful substances — Another substance can sometimes be blamed for the negative side effects of CBD oil, given that there are lots of CBD oil-infused products on the market. Even if CBD oil is of perfect quality, it can be mixed with not-so-good ingredients.  

In addition, less reputable companies may treat the land and plants with poisonous pesticides to have a higher yield. That’s why we always look at third party lab tests.

  • Insufficient amount of CBD — Some CBD oils can have less CBD than it says on the label (and more carrier oil). Even worse, if you change the product but keep the dosage, you could overdose and experience all the negative side effects of CBD.
  • Traces of THC — Some pure CBD oils can contain THC (even though they don’t have to). This is especially dangerous if pure CBD oil is recommended for a child because THC can severely affect the young brain.

In addition to that, THC can make you positive on a drug test as it lingers in your system for a long time. Not all drug tests can discover THC, though.

  • Type of use — Interaction with other medications and similar side effects depends on how exactly you are taking your recommended dose. CBD lotions or creams shouldn’t provide you with high doses of CBD, for instance. 

As for edibles, the adverse effects are less intense than vaping or smoking.

CBD Oil Side Effects Summary

Like every other drug, even the “magical” CBD oil can leave you with adverse side effects. Therefore you must always consult your doctor before taking any form of CBD oil. 

To avoid any potential side effects, make sure you:

  • Always consult your doctor before taking any form of CBD oil.
  • Buy the oil only from reputable suppliers. The same applies if you decide to make your own CBD oil. Always use the best ingredients.
  • Stick to the recommended dose. The majority of issues are connected with overdosing. 
  • Bear in mind how you take CBD oil — via CBD pills, oil, tincture, cream, edibles, or patches
  • Monitor your body and the results you get.  

We hope we managed to explain all there is about CBD and its side effects and that you can enjoy its advantages without any dangers to your health.


Is taking CBD every day bad for you?

Generally, CBD is considered safe. However, cannabidiol is not water. Every body is different and little research has been completed in order for CBD to be declared safe for everyday usage without any breaks.

CBD is not addictive because it doesn’t produce intoxicating effects. Some research even shows it can be used to treat addiction to cocaine and methamphetamine, and nicotine and cannabis

CBD is most known for helping with:

  • Anxiety
  • Insomnia
  • Reducing epilepsy seizures
  • Reducing pain and inflammation

However, when it comes to dosage, consult with your doctor, especially if you’re taking other medications.

Can you have a bad reaction to CBD oil?

Yes, experiencing a bad reaction to CBD is possible. Although most people can tolerate CBD, using it can cause some side effects. The most common are the following:

  • Sleepiness
  • Nausea
  • Appetite boost or loss
  • Dry mouth and sore throat
  • Diarrhea
  • Dizziness
  • Low blood pressure

CBD can also cause tolerance and reverse tolerance. In other words, your body can develop a tolerance to the substance (if there’s THC in the oil). At the same time, if your body develops reverse tolerance, you’ll need smaller doses of CBD.

What drugs should not be taken with CBD?

CBD can interact with other drugs, which can cause various side effects. You should be cautious when mixing CBD with:

  • Clobazam (Onfi) 
  • Valproate.
  • Zonisamide
  • Topiramate (Topamax)
  • Sedative medications (Nembutal, Luminal, Seconal, Duragesic, Sublimaze, morphine, Diprivan, Pentothal)
  • Rufinamide (Banzel)
  • Medications that increase/decrease the breakdown of other drugs by the liver 
  • Medications that decrease the breakdown of other drugs in the liver 
  • Medications changed by the liver

The mentioned drugs can cause severe CBD oil side effects when mixed together.

    1. Hi Janet,
      The general rule of thumb would be to take 10 to 15mg of CBD daily. Monitor how you feel and slowly increase the dosage if needed. Be extra careful about the CBD concentration in the oil you have purchased. If you suffer from any condition, you should consult with your physician before introducing any dosage to your treatment.

  1. so i smoke cbd all the time and when i fully charge my device and hit it multiple times my entire face goes numb starting with my eyes ears mouth then neck. it scares me everytime and i try drinking lots of water to counter the cbd. but most of the time it just has to run its toll. but it scares the absolute shit out of me, any tips?

    1. Hi Thomas! Thank you for contacting us. Here are some instructions by our dr. Djordjevic. First of all, you should check the dosage of CBD that you are using. Next, you should contact the CBD oil manufacturer. Also, check if they have third-party lab results. Reputable companies should have them publicly listed on their sites. Numbness is usually associated with THC, but I guess the product you are using is supposed to be THC-free? Companies also use different artificial additives so as to achieve the right taste and homogeneity. While some CBD vape oils have a couple of natural ingredients, others are loaded with artificial additives.

  2. Hi, how. Long does cbd oil remain in the body causing problems with other medications, regards Graham

    1. Hi Graham, thank you for your question. According to scientific studies, the half-life of CBD when taken orally is about 1 to 2 days. If you’re already taking some medications or plan on using them, make sure you consult with your doctor. Moreover, check which CBD oil would benefit you the most: isolate, full or broad spectrum. Have a good day!

  3. How can I be sure my cbd oil is as pure as advertised and that the source is reputable? What is the significance of time and heat on hemp and cbd oil? I am concerned that the product being offered to me is grown and warehoused in bales for a long time in one rural part of the USA, processed into product, shipped thousands of miles, and then warehoused again in a hot climate before further processing and eventual shipment to customers and then end-users. This scenario is real and raises food-safety concerns to me. Are my concerns valid? What protects consumers? These products are flooding into a demanding consumer market. Again, what concerns are valid? What are the effects of time and heat on hemp cbd oil products, esp. the tincture products that are taken directly sublingually?

    1. Hello Monica! Thank you very much for the comment. It’s true, the market is brimming with hemp and CBD products and since they are still not FDA regulated, there are some manufacturers that do not respect the guidelines. For this reason, we would recommend ordering CBD or cannabis products from one of the companies we have recommended (just take a look at our product or brand reviews). Some companies even offer a 60-day return policy, and all of them agree on returning the product if it arrived in poor shape.

      Usually, the storage practices are top-notch, but a company can’t always vouch for the shipment as the postal services are in charge of that (e.g. CBD gummies can melt a bit due to high temperatures). Hence the return policies. Tracking your order could help minimize the delivery time.

      I believe it would be best for you to choose a company and contact their client support for any specific information on shipping and storage. We are positive you will be completely satisfied with their explanation.

  4. Hello, is CBD oil the same as Hemp Extract? I just took my first CBD gummie containing 10mg Hemp Extract. I took it at 7:30 pm, and slept straight thru til 12:30 pm the next day (17 straight hours). After I awoke up, my entire face feels tingly and I’m so groggy. Is this normal? I bought my gummies from a reputable manufacturer that others I know also buy from.

    1. Hello Traci! From what you are saying, it seems that these gummies are very strong for you. Maybe you should try taking just half of the gummy? It’s not 100% precise technique, but it’s either that or buying gummies with less CBD per gummy. The reaction you felt is normal in the sense that this is what happens when you take a large dose. We are all individuals, so the dose that works wonders for your friend obviously is too potent for you.
      As for CBD oil equalling hemp extract, yes, this is usually the case (there are some false advertisers out there, so one has to be careful). However, bear in mind the hemp extract or CBD can be full-spectrum, broad-spectrum, or isolate, which also makes a difference.
      We hope that you find the right dosage. Let us know how it worked out for you!

  5. So Ive been taking about 10 drops of pure hemp oil with my tea to a help me sleep. On Tuesday night I took 50 drops by mistake, at 7.30 with my tea. WHAM – 10.30pm I wake up with the feeling that my head was exploding from the inside, then my neck – in an hour I was vomiting ….Now 40 hours later I’m still getting the head and neck pains but not as bad….

    Any thoughts on how long this will last and why this happened ?

    1. Hello Clive! What you have described sounds like overdosing on CBD. As with any medicine, the side effects and tolerance differ from person to person. Seems like you have experienced them strongly. I hope you are feeling better now!

  6. I gave my 9-year-old daughter 2 drops of 300mg CBD oil under her tongue 3 times. One in the evening and two times the next day one in the morning and one in the evening. For six months she has been having feeling like someone is punching her over and over again. Her symptoms are now 1000 times worse. She had gotten worse and worse each day. We have gone to the ER and talked with her doctor. They can only recommend ibuprofen and Epsom salt baths. Our anxiety level is at an all-time high. I am basically venting and sharing my experience with others. Thanks for letting me vent. Any thoughts?

    1. Hi Kim! Your daughter needs to be properly examined and diagnosed. Using CBD to treat symptoms is OK but you need to know the diagnosis and what you’re treating. Regards, Dr. Nikola

    1. Hello Lola! I’m pretty sure you are aware that taking CBD oil is helpful, but also there are a lot of other things one has to complete during the weight loss process. Best of luck to you!

  7. I put THC with CBD both 35mg cream Every morning on my shoulders for pain. It has worked good. Now I am having stomach nausea. Would this be from taking
    Every day for the past two weeks. Before that I was taking it periodically.
    Supply from a register store.

    1. Dear Janet,
      There is a possibility that this cream could cause nausea. In order to be absorbed, it would have to be applied to wide skin areas and in thick layers consistently. In the case of absorption, other side effects would probably follow, such as dizziness, mild confusion, and low muscle tone. In general, these side effects are very rare and highly unlikely to happen, if only used on shoulders, once a day.
      It’s more probable that oral medications or supplements would cause such an event if you are using any.
      If the cream is the only thing you’re using at the moment, you should restrain from using it for a week. If the pain disappears, you can start over but use it responsibly.
      If you’ve stopped the cream and nausea still persists, please, contact your attending medical professional doctor for further advice.
      Keep safe!

    1. Dear Sandra,

      Generally, there are no interactions when combining CBD-based creams and statins, so you can safely apply it.
      Be sure that you are applying the cream in accordance with the instructions on the label.
      Also, bear in mind that statins by themselves can on rare occasions give a skin rash. In that case, a skin reaction would be localized on several body areas, not only on the part where you apply the cream.

      Take care!

  8. Use the oil for arthritis, when waking up in am had problem with seeing bright colors of yellow –and bue. Only last a few minutes but enough to scare me . This has happened two times six mo. Between episodes. Thank you .Della

  9. I have been taking a CBD THC tincture for about a month continuously and I have recently developed a cough in the morning and sometimes a night. No pain, just a cough. Can it be from this tincture?

    1. Hello Leslie,
      What you have described sounds like a mild allergic reaction to CBD, provided that all the other conditions are ruled out. For example, whether the tincture has some other ingredients besides CBD extract and the carrier oil, or perhaps you have exposed yourself to some new substances in your environment recently. I would advise stopping the intake for a week and monitoring the changes (if any).

  10. Hi I took the pen and the next day I started getting all these side effects like dizziness, nausea, vivid dreams, loss of appetite, diarrhea, headaches that turn into migraines, I had a migraine for three days and I’m not sure what to do

    1. Hi Melissa, everyone reacts to CBD (or some component of CBD vaping oil) differently. I would advise you to stop using it and see whether your symptoms subside.

  11. i got some cbd drops from a local dispensary i love it for panic attacks and intrusive thoughts but i seem to be getting an itchy throat from it. this has never happened in the past with other oils. would it be the lemon flavoring added to it? it’s an essential oil

    1. Yes, that could be the case. Citrus-based ingredients can act as astringents – substances that contract proteins by absorbing water from the tissue.
      Always study the list of ingredients closely to check for potential irritants.
      There are lots of CBD companies out there adding artificial and natural compounds to improve oil taste or texture. While they are proclaimed safe, that doesn’t mean they’re suitable for everyone.
      I’d recommend taking a look at our page. You can find lots of CBD oil options that only have CBD oil and carrier oil as their ingredients.

  12. I started using a cbd salve 500 mg full spectrum with less than 0.3%thc. I was using on my knee and my hip and ankle. I started having severe heart racing and sweating and anxiety. Is this possible with a salve??

    1. Dear Monica, it is very unlikely for a topical product such as this to cause the side effects you are experiencing. More precisely, when used appropriately, there is a low probability for THC absorption to occur. These side effects could be a consequence of other medications you might be taking, or perhaps a symptom of an underlying condition. On the other hand, if the salve is the only product that you are taking at the moment, you should consider taking a break for one week, in order to allow the body to wash out its metabolites. If during this break period your symptoms disappear, you should consider taking another product. However, if they persist, you should consult your physician for further instructions.

    1. Dear Tom,
      After inspecting the ingredients of several Delta 8 THC gummies, there are no indications that any of them could cause these issues. Therefore, it is likely that this is your body’s reaction to the THC itself, or perhaps to this particular cannabis extract.
      THC-based products can alter digestion, especially when your body is not used to taking them on a regular basis. This means that constipation can occur. The best way to mitigate that is to increase the daily consumption of water.
      Also, pay attention if there are any changes in your diet patterns when you start using cannabis products because an altered diet can also cause constipation.
      If you are using THC for a while now, without any reactions, and having only an issue with this particular brand of gummies, this side effect could be caused by the delta-8 THC extract contained within this product. In this case, we suggest that you perhaps consider switching to another brand.

  13. Hi
    i had a very dry nose
    i dabbed some cbd oil and it was ok
    after that i put a few drops in my nose. and it’s extremely itchy very numb as ifeel like something is cutting it up
    i’ve washed it out with saline
    but is the cbd oil that’s made it worse?

    1. Dear H S,
      There are a number of substances that can irritate the nasal mucosa, including preservatives, antioxidants, and other adjuvant substances. This includes the chemicals used in the process of CBD extraction.
      Therefore, it is unclear what exactly caused your nose’s reaction.
      Nevertheless, it is clear that you experienced an undesired effect. So, please refrain from using it the same way again.
      Furthermore, we would not advise you to apply any CBD-oil product directly in your nose, except when such use is clearly stipulated on the product label.

  14. I took 25 mg of CBD oil under my tongue for my first dose today. About 45 minutes later I started having a bad headache that is still lingering now even four hours later. Could this be a side effect from possibly taking too much to start! I have been ingesting on a almost daily basis now for the last few years full spectrum Cannabis edibles to help me sleep.

    1. Hi Marcie,
      Thank you for your comment. Headache is one of the potential side effects of overdosing with CBD, though what happened could have been attributed to a number of factors. Was 25mg much higher than your usual daily dose of CBD? If the dosage was identical, a possible explanation could be that CBD was metabolized faster this way, and your body wasn’t used to it.

  15. Since taking CBD oil for over a year now I’ve started having sleep apnea. I know CBD oil is a muscle relaxer and as such helps with pain. Sleep apnea happens when you sleep and the muscle in the back of your throat relax and collapse causing you to stop breathing waking you up. Could the CBD oil be causing this. Starting today I’m going to stop using the CBD oil and see. Please let me know what you think?

    1. Hi Roger,
      Thank you very much for your comment. If taking CBD oil was the only change you introduced to your sleeping routine, it is possible that cannabidiol is causing you problems with sleep apnea. However, I cannot vouch for the claim that it happens because CBD relaxes the muscles. The scientific research on the topic of CBD and sleep apnea is insufficient, whereas there have been recommendations both against and for using cannabinoids (and THC in the form of dronabinol) for treating sleep apnea. Therefore, we shall have to remind ourselves once more that CBD can have individual effects on different bodies and that it is always advised that we follow our body’s feedback closely. Have you noticed any changes since you stopped taking CBD oil?

  16. About 3 months ago I switched from Delta 8 to Delta 10 and vape every night to help sleep. After switching from Delta 8 to Delta 10 I developed sever and uncontrollable diarrhea almost daily. It appears I have lost control of my colon when the diarrhea strikes. At other times on the same day, I will have normal bowel movements.

    I have never experienced diarrhea with Delta 8. Delta 10 seems to be much more potent than the 8.

  17. Good Morning,
    I’m considering taking pure CBD oil capsules for ED. i’ve looked at the meds and interactions listed here and don’t think there’s any issues. I have a prosthetic aortal heart valve and will ask my cardiologist his opinion about CBD as well.

    Thanks for posting this information.
