CBG is the biosynthetic precursor of THC and CBD but produces no appreciable intoxication or euphoria. It acts as a weak partial agonist at CB1/CB2 receptors with low affinity, but is a potent α2-adrenergic agonist and 5-HT1A antagonist, which may underlie its alert-yet-calm profile. Human clinical trial data (20 mg oral) demonstrated significant anxiety reduction without cognitive impairment. Safety concerns exist due to α2-adrenergic activation potentially causing sedation, dry mouth, and reduced blood pressure/heart rate. Metabolized primarily by CYP2J2, CYP2C9, CYP2C19, and CYP3A4 enzymes.
