CB-13 is a cannabinoid drug, which acts as a potent agonist at both the CB1 and CB2 receptors, but has poor blood-brain barrier penetration, and so produces only peripheral effects at low doses, with symptoms of central effects such as catalepsy only appearing at much higher dose ranges. CB-13 displays antihyperalgesic activity in a rat model of neuropathic pain with no CNS side effects.
