Also known as STP, 2,5-DIMETHOXY-4-METHYLAMPHETAMINE

A potent, long-lived psychedelic whose R-isomer carries most of the activity while the S-isomer seems to contribute the heavier physical effects. It became infamous when distributed as 'STP' during 1967 in San Francisco, where its unknown identity made overdose emergencies especially difficult to manage.
