Does CBD Have Side Effects?


Whether you believe CBD is a miracle drug or modern-day snake oil, or you’re one of the majority of people who is somewhere in the middle, keeping close to the facts and science and watching them evolve, there’s a question that must always come up, does CBD have side effects? 

There essentially isn’t a drug in the world, medicinal or otherwise, that doesn’t come with a batch of possible effects, and science and anecdotal evidence suggest CBD is indeed the same. 

So, what are the possible side effects of CBD?


CBD Quality

Before getting into the general side effects that may occur as a result of taking CBD, we must first take a second to examine an issue with this less than well-regulated industry. 

Not all CBD products are created equal, and there are, unfortunately, a few bad eggs who are more concerned with their profit margins than the quality of the products they offer to customers. 

As a result, some CBD products do not contain the CBD content they claim to, and can often contain ingredients that aren’t even mentioned on the label. 

As a result, to avoid side effects that it’s impossible to predict, ensure that you are getting your CBD products from a trusted source


The Possible Side Effects of CBD

There are a few side effects that have come up as a result of studies into use of the cannabidiol, but the main one to be aware of is that CBD can interact with existing medications you may be using. 

With reports ranging from the effects of other drugs being lessened or increased as a result of combining them with CBD to thinning of the blood in some rare cases, this is something it’s important to be aware of. 

If you are using any other medication and are considering trying CBD, be sure to speak to your doctor first to make sure you avoid any unpleasant and potentially harmful interactions that may occur. 

For those using CBD alone, the side effects are less severe, with a few people stating they suffered from diarrhoea as a result of CBD use. 

In other cases, fatigue and changes in appetite or weight have been reported, which may be due to interactions between CBD and the endocannabinoid system, which controls various bodily functions including appetite and mood. 

Other less frequently reported side effects include dry mouth and light headaches, these are usually (but not exclusively) said to be experienced by those who vape CBD. 

It is important to keep in mind that if you start experiencing any side effects that you think may be occurring as a result of CBD usage, you should stop using CBD immediately and speak to your doctor. 

It’s possible that these issues are not related, or that a switch in product or CBD content could relieve them, but it’s always better to be safe than sorry, and we do not suggest a trial and error approach. 


How Common are the Side Effects?

It is impossible to know for sure how common CBD side effects are, simply because many people who use CBD choose not to talk about it publicly, due to the stigma that is still attached. 

However, it does seem that side effects are not consistent, in that no side effect seems to be particularly common, and there are certainly numerous people who use CBD with no side effects at all. 

Obviously, as the science continues, and discussion of CBD becomes more comfortable for people (which is something that is undoubtedly happening) we will continue to update this article and bring new information wherever it is necessary, or we feel it could be useful. 

Until then, we repeat the advice from above, if you are experiencing side effects from CBD, or if you are using any other medication, speak to your doctor before either starting or continuing to use CBD products, and as always, if you have any concerns or questions, shoot us a message and we will be more than happy to discuss it with you.
