This article originally published at the-libertarian.co.uk. As I mentioned in a recent article, the Multidisciplinary Association for Psychedelic Studies (MAPS) is funding MDMA PTSD research as its top priority. However, the organization also seeks to allow the medical use of certain other Schedule I drugs. These include the well-known psychedelic drug LSD, so called as an abbreviation for its German name, Lysergsäure-diathylamid (in English, lysergic acid diethylamide). This substance was largely popularized by former Harvard University psychology professor Timothy Leary, and the resulting hysteria and prohibition has stifled its legitimate medical use for years.
