Mescaline is used primarily as a recreational drug and is also used to supplement various types of meditation and psychedelic therapy. It is classified as a schedule I drug in the U.S., making it illegal in all forms; however, it remains legal in certain religious ceremonies registered by the Native American Church Schedule I drugs have a high potential for abuse, no currently accepted medical use in treatment in the United States, and a lack of accepted safety for use under medical supervision.
