5-MeS-DMT, also known as 5-methylthio-N,N-dimethyltryptamine or as 5-methylthio-DMT, is a lesser-known psychedelic drug of the tryptamine family. [1] It is the 5-methylthio derivative of dimethyltryptamine (DMT) and is an analogue of 5-MeO-DMT. [1]
In his book TiHKAL (Tryptamines I Have Known and Loved), Alexander Shulgin lists the dose as 15 to 30 mg smoked and its duration as less than 1 hour. [1] In individual reports, the duration was 10 to 30 minutes. [1] The effects included feeling stoned and no visuals, among others. [1] It was also described as coming on very fast and being quite intense. [1] The drug is described as being about half as potent as 5-MeO-DMT. [1]
5-MeS-DMT was less potent than 5-MeO-DMT and psilocin (4-HO-DMT) but more potent than 4-MeO-DMT or 4-MeS-DMT in rodent behavioral studies. [2] [3] [4]
It was first described in the scientific literature by Richard Glennon and colleagues by 1982. [2] [3] [4] However, 5-MeS-DMT was synthesized and tested by Shulgin as early as 1979. [5]
