Potential Side Effects Of CBD Oil Usage

CBD oil has been in the news a lot lately, and there is no denying that many people find it helpful for alleviating their chronic symptoms. It is even being used to treat epilepsy in dogs! Of course, as is the case with any drug or dietary supplement, there are some potential side effects of CBD oil. For the most part, they appear to be pretty mild. Even so, scientists do not yet know what the long-term effects of CBD use will be. 

That being said, here are a few of the known potential side effects, as well as a little extra info on possible drug interactions and product purity issues. 

Neuro-psychiatric Side Effects Of CBD Oil 

The side effects of CBD oil are both physiological and neuro-psychiatric in nature. Since cannabidiol (CBD for short) acts on endocannabinoid receptors in the brain, it has the ability to change your mood. Much anecdotal evidence suggests that changes are for the better. However, that might not always be the case.

Here and there, those who have used cannabidiol have reported increases in anxiety and decreases in overall mood. Still, there is no real data to prove or disprove that CBD oil was responsible or that, even in high doses, it poses such a risk.

Physiological Side Effects Of CBD Oil

Usually, CBD users report physiological side effects, but even these are somewhat infrequent. According to numerous studies, people often report fatigue, nausea, vomiting, diarrhea, and other signs of gastrointestinal upset. Others have occasionally reported weight and appetite changes.

However, please note that these studies were done on Epidiolex in particular, a drug that is now being used to treat epilepsy. This drug might have other side effects that are unique to it and not to CBD oil overall.

Possible Drug Interactions

All drugs and dietary supplements have the potential to negatively interact with other drugs and supplements. (Hence why speaking with your doctor prior to starting an oil is so important!) And cannabidiol does have a few possible drug interactions.

Its most serious interactions are with Norco (acetaminophen), morphine, and tramadol. It does have more moderate interactions with sleep medications, muscle relaxants, antidepressants, and anti-anxiety meds.

Product Purity

Here at Happy Tea, we are upfront about what we put in our products. But that isn’t how all manufacturers operate. While Happy Tea products are safe, it’s still a good idea to check with your doctor before trying a new supplement.

That being said, know that the United States Food and Drug Administration (FDA) does not regulate the production of cannabidiol products. (However, it has considered doing so.) That leaves some companies room to put out impure products. The 2018 Farm Bill lifted heavy regulations on hemp, which is no longer considered a controlled substance.

While this is certainly a good thing in many ways, it has left many feeling uncertain about product purity. Many cannabidiol products are probably safe to use, but it can’t hurt to check in with and get some recommendations from your doctor.


Overall, cannabidiol has very minimal potential for serious side effects, and the most reported one seems to be feeling more tired. If you’re struggling with chronic health issues, cannabidiol might be able to help. It’s non-psychoactive and, with minimal side effects, is relatively harmless for most people.
