Thiomescaline (TM) is a pair of lesser-known psychedelic drugs with the molecular formula C11H17NO2S. 3-TM and 4-TM are analogs of mescaline in which an oxygen atom has been replaced with a sulfur atom. They were first synthesized by Alexander Shulgin and described in his book PiHKAL.[http://www.erowid.org/library/books_online/pihkal/pihkal155.shtml 3-TM entry in PiHKAL][http://www.erowid.org/library/books_online/pihkal/pihkal156.shtml 4-TM entry in PiHKAL] Very little data exists on the pharmacological properties, metabolism, and toxicity of thiomescaline.{{Citation needed|date=April 2011}}
