Proscaline, or 4-propoxy-3,5-DMPEA is a psychedelic and hallucinogenic drug, used by some as an entheogen. It has structural and pharmacodynamic properties similar to the drugs mescaline and escaline.


Proscaline is in a class of compounds commonly known as phenethylamines, and is the 4-propyloxy homologue of mescaline. The full name of the chemical is 4-propyloxy-3,5-dimethoxyphenethylamine.


Proscaline produces psychedelic effects that can last 12 hours.


The mechanism that produces proscaline’s hallucinogenic and entheogenic effects is unknown.


The toxicity of proscaline is not known.


Proscaline is unknown on the black market. Limited accounts of proscaline can be found in journal articles, and in the book PiHKAL.


Proscaline is unscheduled and unregulated in the United States, however its close similarity in structure and effects to mescaline could potentially subject possession and sale of proscaline to prosecution under the Federal Analog Act. This seems to be the tack the federal government is taking in the wake of the DEA's Operation Web Tryp. A series of Court Cases in the US involving the prosecution of several online vendors in ongoing as of 2004.
