Cyclopropylmescaline

CPM, or 4-cyclopropylmethoxy-3,5-dimethoxy-phenethylamine, is a lesser-known psychedelic drug. CPM was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the dosage range is listed as 60–80 mg, and the duration listed as 12–18 hours. CPM produces powerful closed-eye imagery, visuals, and fantasies. It also causes enhancement of music. Very little data exists about the pharmacological properties, metabolism, and toxicity of CPM.
