THCV

Definition: THCV (tetrahydrocannabivarin) is a cannabinoid closely related to THC, with a shorter side chain on its molecule. It’s usually present in small amounts, though some strains, often traced to African landraces, contain more. THCV is marketed for appetite control and energy, but nearly all evidence comes from animal and lab studies.

How Is THCV Different From THC?

THCV and THC look similar, but they act differently at the CB1 receptor. Research reviewed by Ethan Russo suggests that at low doses THCV blocks CB1, while at higher doses it may activate it. That means it may feel very different depending on the amount, and it’s not simply a weaker THC.

Does THCV Suppress Appetite?

That’s where the “diet weed” nickname comes from. In obese mice, THCV reduced weight, body fat, and leptin levels while increasing energy use. Those results are interesting, but human trials are small and limited. There’s no solid proof THCV helps people lose weight, so be wary of products making that promise.

Does THCV Get You High?

At low doses, THCV is generally considered mildly or non-intoxicating. At higher doses, effects may become noticeable. Many THCV products also contain THC, so check lab results before you try one.

Where Is THCV Found?

Like other cannabinoids, THCV forms in the trichomes, starting as the acid THCVA and converting when heated. You’ll find it in specialty flower, gummies, and tinctures. Strain names alone won’t tell you much, since amounts vary widely.
