What is THCv?

THCv is THC's energetic cousin, with a shorter carbon chain that changes its effects dramatically. At low doses, THCv acts as a CB1 antagonist—it blocks the receptor rather than activating it. This is why it's associated with appetite suppression and clear-headed energy. At higher doses, THCv becomes a CB1 agonist like THC, producing psychoactive effects, but the high is described as shorter, clearer, and more stimulating. THCv is naturally found in African sativa landraces like Durban Poison but is rare in most commercial strains.

How It Works

THCv's effects depend on dose. At low doses, it's a CB1 antagonist—it blocks the receptor, explaining appetite suppression and lack of intoxication. At higher doses, it becomes a CB1 agonist like THC. It also interacts with CB2 receptors and may affect 5-HT1A serotonin receptors.
