It has structural properties similar to the drugs mescaline, isoproscaline, and escaline.
In PiHKAL, Alexander Shulgin reports that a dose of 30–60 mg produces effects lasting 8–12 hours.
[1] Proscaline is in a class of compounds commonly known as phenethylamines, and is the 4-propoxy homolog of mescaline.
Proscaline is not directly scheduled under the Controlled Substances Act.
However, due to its structural similarities with mescaline, a Schedule I drug, it could potentially be subject to the same control measures and penalties for possession and manufacture under the Federal Analogue Act.
