CBD oil is considered therapeutic and low-risk for most users.
However, CBD oil may result in the following adverse effects:
Inhibited liver function: The liver regulates the way different drugs are metabolized within the body; this process is known as hepatic drug metabolism. Higher-than-average doses of CBD oil can slow the hepatic drug metabolism process. As a result, users may not be able to process other drugs as quickly. This is particularly concerning for CBD oil users who also take prescription medications.
Dry mouth: As is the case with many other hemp- and marijuana-based products, CBD oil often leads to a condition known as dry mouth (or cottonmouth). This is likely due to cannabinoids altering receptors in the lower jaw that trigger salivation. In most cases, mild discomfort and stronger-than-average thirst are the only issues associated with dry mouth.
Decreased blood pressure: CBD oil may incite a small drop in blood pressure immediately after it is consumed; this may also cause the user to feel lightheaded. These effects typically wear off within hours, although people who take prescription medication should check with their doctor to ensure the oil won’t counteract the effects of other drugs.
Diarrhea: Diarrhea is a common side effect for people who take relatively large doses of CBD oil, and is linked to the substance interacting with the digestive system. Lowering oil doses often minimizes this effect.
Changes in appetite: CBD oil may make users feel hungrier than usual, which is a common effect of most cannabinoids.
***Lastly, as we’ve discussed, CBD oil tends to make users feel excessively tired or drowsy. This may be the desired effect. However, it’s important to note that operating a vehicle or heavy machinery after taking CBD oil — especially higher doses — can increase one’s risk of being involved in an accident.***
