100mg of THC 50mg of THCV Tetrahydrocannabivarin (THCV) is a, non-psychoactive or mildly psychoactive cannabinoid found in the cannabis plant, primarily in certain Sativa strains. While structurally similar to Delta-9 THC, THCV differs in its molecular chain and its effects on the body, often acting as a CB1 receptor antagonist (blocking the receptor) rather than an agonist (activating it) at lower doses. It is frequently referred to as "diet weed" or "weederall" due to its reported appetite-suppressing and energizing properties.
