How available is Mescaline?

Answer 1

Various studies were conducted on peyote/mescaline during the 20th Century. No useful medical application of the drug was found. Peyote/mescaline was banned in the U.S. in 1967 and placed on Schedule I in 1970. You can purchase Peyote seeds as well as other cacti containing mescaline online. It should be noted that what is sold as "mescaline" on the street is typically another psychedelic such as LSD.
