MET Stats & Data

MET was first documented in scientific literature in 1981, appearing in Michael Valentine Smith's book "Psychedelic Chemistry." The compound subsequently received a brief entry in Alexander Shulgin's 1997 publication "TiHKAL" (Tryptamines I Have Known and Loved), though it did not receive extensive characterization in that work. The substance emerged on the European drug market as a novel designer drug in 2014, marking its first appearance in recreational contexts. By mid-2016, MET had become available through online research chemical vendors, where it continues to be distributed for recreational and entheogenic purposes.

The toxicity and long-term health effects of recreational MET use do not seem to have been studied in any scientific context and the exact toxic dose is unknown. This is because MET is a research chemical with very little history of human usage. Anecdotal evidence from people within the community who have tried MET suggest that there are no negative health effects attributed to simply trying the substance by itself at low to moderate doses and using it very sparingly (but nothing can be completely guaranteed). Independent research should always be done to ensure that a combination of two or more substances is safe before consumption. It is strongly recommended that one use harm reduction practices when using this substance.

Effects aggregated from 9 experience reports (9 single-substance Erowid)

Each bar is the share of reports mentioning the effect; its whisker, and the band on the rows below, is the 95% interval: where the share could plausibly be with other reports of the same kind.

Too few reports for bars: these effects come from 9 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

From 15 of 21 recorded dose entries: those that state a weight (mg, g or µg), in routes with at least five of them. Values above Q3 + 3×IQR, far above what people typically take, are left out; they can include real heavy doses and overdoses, not only mistakes.
