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 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 completely due to this psychoactive ingredient. Getting “high” used to be seen as the ultimate crime. At the same time, the medical benefits of cannabis were hard to deny. That said, when CBD was discovered, people were inclined to believe CBD effects are what makes cannabis such a powerful healer.
Let’s first take a quick look at what CBD is, and then you’ll find out everything there is to know about its detrimental effects.
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 80 cannabinoids within cannabis. These natural substances have the ability to bind to our own endocannabinoid system. This is the reason 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 CBD oil side effects, let’s first explain what the oil actually represents.
There are two types of 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 of CBD, THC, and all the other cannabinoids you can find in a cannabis plant. Terpenes come into the picture as well.
Side Effects of CBD Oil
Similar to any medicine, CBD oil comes with a (long) list of warnings. And just like it is the case with any other, the side effect may or may not exhibit themselves. Regardless of the reason, the fact remains that some people will endure the negative effects.
One of the biggest reasons for this is the fact 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 so as 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, 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. In addition, CBD oil for anxiety and reduced anxiety levels usually encourage people to eat more. The appetite-boosting quality is mostly connected with full-spectrum CBD oil.
One of the most common CBD oil side effects is dry mouth. 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.
The side effects of CBD oil in dogs and humans may appear in this form. Here are two reasons why you may 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 oil benefits and side effects and the new eating pattern. In case you are already suffering from diabetes or similar appetite/weight loss condition, be very careful about maintaining your goal weight.
On the one hand, this 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.
In another research, though, it was 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.
Dizziness due to CBD oil normally 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 unexpectedly.
Dizziness could be caused by low blood pressure too.
CBD oil is actually recommended for treating Parkinson’s. Evidence of abuse is scarce.
Usually, patients are advised against using CBD if it interacts with some other medications. Mood changes, diarrhea, and tiredness may occur in these cases.
More serious side effects such as worsening the disease symptoms occur with too high dosage.
Grapefruit and CBD pills side effects can be identical. Grapefruit and similar fruit contain certain substances that interact with CYP450 enzymes in particular. In short, it prevents them from doing their job of dealing with the drugs we take. This way, too much medicine goes straight to the liver and isn’t processed before entering the bloodstream. Eventually, you end up with more drug that you are entitled to.
CBD behaves in a similar way. What is worse, it interferes with more enzymes (CYP3A4 and CYP2D6) and increases the drug level even more. Quitting CBD oil usage doesn’t let your body use the drug normally until a few days have passed.
In this respect, side effects of CBD oil will show if a person is taking some 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 recently made the 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 if your liver is healthy, they will occur only with extremely high doses.
Headaches and Migraines
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. Not all CBD oil for pain brands are reliable, so sometimes, a simple change of CBD brand will end the pain.
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, you may be in for a surprise. 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, these side effects of CBD oil are very dangerous. For instance, 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 your doctor.
Allergy to CBD
What are the side effects of CBD oil? Some of them are allergy symptoms.
An allergy to cannabis 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 by eating some of the delicious edibles. What is more, you may have a mild allergy to cannabis, but it could make other allergies stronger, particularly food allergies.
If you are taking CBD oil for the first time, beware of these side effects of CBD oil in humans — 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 have 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.
It will interact with the following, so we strongly advise you against using CBD with:
- Clobazam (Onfi), and
CBD may interact with:
- Topiramate (Topamax)
- Sedative medications (CNS depressants), such as Nembutal, Luminal, Seconal, Duragesic, Sublimaze, morphine, Diprivan, Pentothal, and others.
- Rufinamide (Banzel).
- Medications that increase/decrease the breakdown of other medications by the liver:
Tagamet, Luvox, Prilosec, Ticlid, Topamax, Tegretol, Dilantin, Mycobutin, etc.
- Medications that decrease the breakdown of other medications 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?
So far, research on CBD oil dangers during pregnancy hasn’t been conducted. The existing studies all rely on cases when mothers-to-be were regular cannabis consumers. 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 side effects of CBD oil. 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 — believe it or not, CBD oil is not FDA regulated. It is isn’t even listed as an FDA-approved dietary supplement. How is this possible? Most probably, the main reason for mistrust would be that 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).
CBD oil reviews without an official FDA stamp of approval may not be reliable at all. Not being FDA “blessed” gives enough chance to manufacturers to advertise the products as they wish and alter CBD oil’s content without harsh penalties.
- Traces of THC — you could end up with more than you’ve bargained for. Some pure CBD oils may contain THC (even though they mustn’t). This is especially dangerous if a child is recommended pure CBD oil as THC is detrimental to young neural paths. In addition, that can make you positive on a drug test as THC lingers in your system for a long time. Not all drug tests can discover THC, though.
- Harmful substances — sometimes, you may think you’re dealing with the negative side effects of CBD oil, but another substance is to blame. There are lots of CBD oil-infused products out there. Even if CBD oil is of perfect quality, it can be mixed with not-so-good ingredients.
The latest example comes in the form of vaping respiratory disease. It has already taken seven lives. The jury is still out, but the CBD vape oil side effects could be attributed to a harmful substance added to vaping liquid.
In addition, less reputable companies may treat the land and plants with poisonous pesticides to have a higher yield.
- Insufficient amount of CBD — some CBD oils can have less CBD than it says on the label and more of carrier oil. Consequently, your condition requiring CBD won’t improve. Even worse, if you change the product but keep the dosage, you could overdose on CBD and experience all the negative side effects of CBD.
- Type of use — interaction with other medications and similar side effects depend a lot on how exactly you are taking your recommended dose. CBD lotions or creams shouldn’t provide you with high doses of CBD. As for CBD edibles, CBD gummies side effects are felt less compared to taking CBD via vaping, smoking, or sublingually.
So what can we say about CBD oil in the end? First of all, don’t get carried away by the worldwide frenzy.
- Always consult your doctor before taking any form of CBD oil.
- Buy the oil only from reputable suppliers. These should always state their products were tested by independent laboratories, and their findings should be available. The same applies if you decide to make your own CBD oil. Always use the best ingredients.
- To avoid CBD oil side effects, you are to 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.
Finally, monitor your body and the results you get. CBD oil benefits are just too good to be missed. Hopefully, you are fully eligible to enjoy its advantages without any dangers to your health.
