THCV Oral Strips Produced Significant Weight Loss and Metabolic Improvements Over 90 Days

In a placebo-controlled trial of 44 subjects, THCV/CBD mucoadhesive strips taken daily for 90 days produced statistically significant weight loss, reduced abdominal girth, and improved cholesterol and blood pressure.

What This Study Found

THCV/CBD oral strips produced statistically significant weight loss, decreased abdominal girth, reduced systolic blood pressure, and lowered total and LDL cholesterol compared to placebo. The higher dose (16 mg THCV/20 mg CBD) was superior to the lower dose (8 mg THCV/10 mg CBD) for weight loss, and both differed significantly from placebo.

Key Numbers

44 subjects, 90 days. Low dose: 8 mg THCV/10 mg CBD. High dose: 16 mg THCV/20 mg CBD. Both doses: significant weight loss vs. placebo. High dose superior to low dose for weight loss. Significant decreases in abdominal girth, systolic BP, total and LDL cholesterol.

How They Did This

Placebo-controlled study of 44 subjects (31 females, 13 males, average age 51.75) evaluating two doses of THCV/CBD via mucoadhesive oral strips taken once daily for 90 days. Outcomes included weight, abdominal girth, blood pressure, and cholesterol.

Why This Research Matters

THCV is a CB1 neutral antagonist, and this is among the first human trials testing whether its proposed metabolic effects translate to actual weight loss and metabolic improvements in a controlled setting.

The Bigger Picture

The CB1 antagonist approach to weight loss was previously explored with rimonabant, which was withdrawn due to psychiatric side effects. THCV's neutral antagonism (rather than inverse agonism) may offer a safer profile, but much larger trials are needed to confirm both efficacy and safety.

What This Study Doesn't Tell Us

Very small sample size (44 total, even smaller per group). No details on randomization or blinding methodology. Combined THCV with CBD, so individual contributions are unclear. 90-day follow-up does not address long-term sustainability. Limited demographic diversity.

Questions This Raises

  • ?How much weight loss is attributable to THCV vs. CBD?
  • ?Would the effects persist beyond 90 days or reverse after stopping?

Frequently Asked Questions

What is THCV?

Tetrahydrocannabivarin (THCV) is a cannabinoid that acts as a neutral antagonist at CB1 receptors, which are involved in appetite and energy regulation. Unlike THC, it does not produce intoxication at these doses.

Can THCV help with weight loss?

This small trial suggests it may, with significant weight loss observed over 90 days. However, the study combined THCV with CBD and had only 44 participants, so larger trials are needed to confirm.
