title: Effect of cannabinoids on the activity of monoamine oxidase in normal human platelets.
abstract: Platelet MAO activity was affected by preincubation with cannabinoid derivatives in vitro. The psycho-active derivative delta 1-THC inhibited MAO activity in platelets to an extent varying according to its concentration while CBD and (+) delta 6-THC had no inhibitory effect. (-) delta 6-THC, which is minor psychomimetic component, had less inhibitory effect on MAO activity than delta 1-THC. However, (-) DMH delta 6-THC revealed no attenuation effect on MAO inspite of its well-known psychomimetic activity.
