Tetrahydrocannabivarin is Not Tetrahydrocannabinol.

Abstract

Tetrahydrocannabivarin (THCV) is a phytocannabinoid that is becoming popular across the North American cannabis market. THCV has been reported to reduce blood sugar and act as an appetite suppressant in several independent pre-clinical studies, which has earned it the popular nickname of "diet weed," despite few human studies of these effects. Additionally, THCV is usually and incorrectly categorized as an intoxicating analogue of tetrahydrocannabinol (THC), which causes confusion among both consumers and regulators. In this article, we examine what is known pre-clinically and clinically about THCV, as well as highlight mechanisms of action, in order to clarify the scientific differences between THCV and THC. THCV, although structurally similar to THC, has distinct pharmacological activity and physiological effects at the doses currently reported in the literature. We highlight areas of opportunity for further THCV research in order to determine the full and appropriate potential for unique health, wellness, and therapeutic applications of this compound.
