Perhaps I don't know the right terminology. Ketamine, which the source article is mostly focused on, is significantly addictive. The author calls it a psychedelic, although I see other sources use that term more narrowly. LSD and MDMA, sure, are non-addictive, although LSD is active at such small doses that I'd have other concerns about making it widely available.
