Does CBD have any side effects?

CBD oil has become an incredibly popular and sought after product. The hemp-derived CBD industry is expected to crack $646 million (€580 mill.) by 2022. Products have popped up everywhere, from health stores to gas stations, and the appeal is clear. Who doesn't want a potential new way to sleep better or enhance their wellbeing? Who doesn't want to try a new path toward pain management? These reported benefits, and more, have drawn countless customers to pick up some products of their own. However, with all of these people putting it in their bodies, does CBD have any side effects?


Well, according to the World Health Organisation, CBD has a good safety profile. Along with that, they reported that it doesn't show any potential for dependence or abuse. This report also discussed the lack of serious side effects in the studies they observed. Side effects of CBD are uncommon. However, this doesn't mean that no side effects exist, or that they’re completely absent in these studies.


As with any substance that goes into your body, there's always a small chance it can come with side effects. The fact of the matter is, our bodies all work differently, especially when it comes to the endocannabinoid system. The effects of CBD, then, might be ever so slightly different for you than they are for the friend who recommended it to you. With that in mind, let's take a look at some of the possible side effects.


Cbd may make your mouth feel dry

A somewhat annoying side effect, CBD has a chance to make your mouth feel dry. Nothing too serious, just the odd feeling of not having as much saliva in your mouth as usual. CBD is a cannabinoid and therefore interacts with cannabinoid receptors in the body. Why is that relevant, you wonder? In short, according to a study performed in 2006, interplay with cannabinoid receptors leads to decreased saliva production, a.k.a. dry mouth. It does not always happen, but can in certain people. 


While not as prevalent as dry mouth, some CBD users should be prepared for the possibility of feeling tired. In a year-long study on CBD in epilepsy patients, researchers found that 13% of their patients experienced fatigue during the trial. That being said, the severity of this fatigue is not made clear, nor is whether these patients were taking antiepileptic medications during the study. Considering this, the majority of people shouldn't have anything to worry about, unless the aim is to induce sleep, in which case CBD is better paired with melatonin supplements to help and enhance restfulness.  


This is less of a side effect of CBD itself, and more of a side effect of one of the benefits. As far as the benefit, in a randomised, placebo-controlled study, CBD was shown to significantly decrease blood pressure. This is a desirable effect for many users of the substance, but it doesn't work out well for everyone. If your blood pressure is already fairly low, CBD might bring it down to the point where dizziness becomes an issue. If you let it get especially low, you might even experience fainting, but that would only be an issue in the most severe cases. If you're really worried, get your blood pressure checked before taking CBD to make sure it's not below standard.


Lastly, those taking other medications should consider how CBD will interact with them. We won't go into too much detail here, as we want to discuss this at length in a future piece. However, it's worth bringing up here as well. As we mentioned earlier, it's not clear whether symptoms experienced by those in the epilepsy study were affected by the conflation of CBD and their medications. As another general review into CBD's safety also mentioned, further trials need to be done to see how it interacts with other drugs. Your doctor will know better than anyone, though, so we recommend you wait for their judgement and discuss it with them if you are worried.


Although side effects are uncommon, its always good to start small and see how a new supplement affects you. Once you're aware of how it interacts with your system, of course, you can increase the dosage to your liking (within reason). Remember, your body will quickly process CBD oil, so you'll notice the effects quickly.

Lastly, if you feel you have any medical issues that taking CBD could impact, talk to your doctor and see whether it's right for you. It might seem excessive, but this is your health we're talking about. Even if the substance doesn't get you high, you still need to make sure you're taking it safely.
