Source-derived summary

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. It is the 5-methylthio derivative of dimethyltryptamine (DMT) and is an analogue of 5-MeO-DMT.

Use and effects

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. In individual reports, the duration was 10 to 30 minutes. The effects included feeling stoned and no visuals, among others. It was also described as coming on very fast and being quite intense. The drug is said to be about half as potent as 5-MeO-DMT.

Interactions

Pharmacology

Pharmacodynamics

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. It is known produce generalization with 5-MeO-DMT in rodent drug discrimination tests, with only slightly lower potency in comparison.

Chemistry

Synthesis

The chemical synthesis of 5-MeS-DMT has been described.

Analogues

Analogues of 5-MeS-DMT include dimethyltryptamine (DMT), 5-MeO-DMT, 5,N,N-TMT (5-methyl-DMT; 5-Me-DMT), HBL20016 (5-MeS-6-F-DMT), and HBL20017 (4-F-5-MeS-DMT), among others.

History

It was first described in the scientific literature by Richard Glennon and colleagues by 1982.

Editorial summary

The public source identifies “5-MeS-DMT” as chemical compound. This brief keeps that definition visible, then builds a research path around 5-MeS-DMT, chemical and compound.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—1982—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with 5-MeS-DMT, chemical and compound providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “5-MeS-DMT”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Apr 4, 2026. The linked authority identifier is Q4639632. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1982.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
