4-AcO-MET, also known as 4-acetoxy-N-methyl-N-ethyltryptamine or metacetin, is a psychedelic drug of the tryptamine family. It is the acetate ester of 4-HO-MET, and a homologue of 4-AcO-DMT. It is a novel compound with very little history of human use.{{cite web|title=New psychoactive substances reported to the EMCDDA and Europol for the first time in 2009 under the terms of Council Decision 2005/387/JHA|url=https://www.emcdda.europa.eu/attachements.cfm/att_101538_EN_Annex%202.pdf|website=www.emcdda.europa.eu|access-date=6 May 2022}} It is sometimes sold as a research chemical by online retailers.

Pharmacology

Due to its similarity to the psilocin prodrug 4-AcO-DMT, which is deacetylated to form psilocin in vivo,{{cite journal | vauthors = Nichols DE | date = February 1999 |title= Improvements to the Synthesis of Psilocybin and a Facile Method for Preparing the O-Acetyl Prodrug of Psilocin |url=http://www.thieme-connect.de/DOI/DOI?10.1055/s-1999-3490 |journal=Synthesis |volume=1999 |issue=6 |pages=935–938 |doi=10.1055/s-1999-3490| s2cid = 32044725 |url-access=subscription }}{{cite journal | vauthors = Pham DN, Chadeayne AR, Golen JA, Manke DR | title = Psilacetin derivatives: fumarate salts of the meth-yl-ethyl, meth-yl-allyl and diallyl variants of the psilocin prodrug | journal = Acta Crystallographica Section E | volume = 77 | issue = Pt 2 | pages = 101–106 | date = February 2021 | pmid = 33614134 | pmc = 7869532 | doi = 10.1107/S2056989021000116 | bibcode = 2021AcCrE..77..101P }} it is expected that 4-AcO-MET is also quickly hydrolyzed into 4-HO-MET by serum esterases, but human studies concerning the metabolic fate of this drug are lacking.

=Legal status=

==Switzerland==

In Switzerland, 4-Acetoxy-MET is a controlled substance under Verzeichnis E.{{cite web|title=Fedlex|url=https://www.fedlex.admin.ch/eli/cc/2011/363/de|access-date=2021-08-15|website=www.fedlex.admin.ch}}

==United Kingdom==

In the United Kingdom, 4-AcO-MET is a Class A drug in the United Kingdom because it is an ester of the drug 4-HO-MET, which is a Class A drug under the tryptamine catch-all clause.{{cite web|date=2021-08-15|title=Misuse of Drugs Act 1971|url=https://www.legislation.gov.uk/ukpga/1971/38/schedule/2/part/I|url-status=live|archive-url = https://web.archive.org/web/20121111193914/http://www.legislation.gov.uk/ukpga/1971/38/schedule/2/part/I |archive-date = 2012-11-11 }}

==United States==

In the United States, 4-Acetoxy-MET is not scheduled. It may be considered an analogue of psilocin, a Schedule I drug under the Controlled Substances Act. As such, the sale for human consumption or the use for illicit non-medical purposes could be considered a crime under the Federal Analogue Act.{{cite web |title=21 U.S. Code § 841 - Prohibited acts A |url=https://www.law.cornell.edu/uscode/text/21/841 |access-date=2016-08-02 |website=LII / Legal Information Institute |mode=cs2}}
