CBG (Cannabigerol)
A non-intoxicating minor cannabinoid promoted for anxiety and inflammation. One small controlled human trial suggests an acute anti-anxiety effect; almost everything else is preclinical or self-reported.
Evidence last reviewed: August 2026
What the science says
- Acute anxiety and stress Limited evidence
A double-blind, placebo-controlled crossover field trial in 34 healthy adults found that a single 20 mg dose of CBG reduced self-reported anxiety and, in one measure, stress, without impairing cognition. This is a single small acute study and has not been replicated.
- Self-reported benefits in users Limited evidence
A survey of 127 people using CBG-predominant cannabis preparations reported perceived improvements in anxiety, chronic pain and sleep, with mild adverse effects such as dry mouth. Survey data cannot separate a drug effect from expectation.
- Anti-inflammatory and other uses Limited evidence
Claims about inflammation, gut disease and antibacterial activity rest on cell and rodent studies. A small randomized trial of a CBD/CBG beverage powder for exercise-induced muscle soreness was a pilot safety study, not a demonstration of efficacy.
