O-823 is a drug which is a cannabinoid derivative that is used in scientific research. It is described as a mixed agonist/antagonist at the cannabinoid receptor CB₁, meaning that it acts as an antagonist when co-administered alongside a more potent CB₁ agonist, but exhibits weak partial agonist effects when administered by itself. ^{[1] [2] [3]}
