Cannabinoid and hemp products are known for having few if any negative side effects. However, cannabinoids may have negative interactions with prescription drugs. If you are taking prescription drugs, you should check with your physician to make sure cannabinoids are safe for you to take.
Other very minor side effects could include dry mouth, a slight drop in blood pressure, drowsiness, and lightheadedness. The majority of people will not experience these side effects, but, if they do, they are normally very subtle.
