Thiomescaline

TM, or thio mescaline, is a series of lesser-known psychedelic drugs similar in structure to mescaline. They were first synthesized by Alexander Shulgin and written up in his book PiHKAL (Phenethylamines i Have Known And Loved). Very little data exists on the pharmacological properties, metabolism, and toxicity of Thiomescaline.^{[citation needed]}
