This was a small, randomized, double-blind, placebo-controlled 13-week pilot trial of two nonpsychoactive cannabis-related compounds (cannabidiol, CBD, and tetrahydrocannabivarin, THCV) in 62 people with type 2 diabetes who were not using insulin. Participants were assigned to CBD, THCV, two CBD/THCV combination doses, or placebo. Compared with placebo, THCV lowered fasting…

This study tested the cannabinoid THCV in two kinds of obese mice and in insulin-resistant liver and muscle cells. THCV did not change food intake or body weight, but it briefly raised energy use and improved how the animals handled glucose. In obese mice, THCV improved glucose tolerance and insulin…

Journal of Cannabis Research Summary & key facts 2020 80 citations

THCV is a cannabis compound that does not cause the “high” linked to THC. In animal studies it lowered appetite, increased feelings of fullness, and raised energy use, and some small studies in people with type 2 diabetes found lower fasting blood sugar versus placebo. Researchers say these findings make…

AIMS neuroscience Summary & key facts 2025 5 citations

This article reviews evidence that tetrahydrocannabivarin (THCV), a non-psychoactive compound from Cannabis sativa, may help with obesity and type 2 diabetes. In lab and animal studies THCV reduced appetite, improved insulin sensitivity and glucose uptake, lowered fat buildup, and boosted energy function in fat and liver cells. Early human trials…
