Chemical Class

Cyclopropylmescaline (CPM) is a psychedelic phenethylamine in the scaline family, related to mescaline. Alexander Shulgin produced it and described it in scientific literature by 1994. PiHKAL reports a duration of 12–18 hours and describes prominent eyes-closed imagery in an account involving 70 mg1. Chemically, CPM replaces mescaline’s methoxy methyl group with a cyclopropylmethyl group1.
