5-MeO-DMT (5-methoxy-N,N-dimethyltryptamine) is a powerful psychedelic tryptamine. It is found in a wide variety of plant and psychoactive toad species and, like its close relatives DMT and bufotenin (5-HO-DMT), it has been used as an entheogen by South American shamans for thousands of years.
5-MeO-DMT was first synthesized in 1936, and in 1959 it was isolated as one of the psychoactive ingredients of Anadenanthera peregrina seeds used in preparing Yopo snuff. It was once believed to be a major component of the psychoactive effects of the snuff. It occurs in many organisms that contain bufotenin (5-OH-DMT), and is the O-methyl analogue of that compound. It is metabolized mainly by CYP2D6.
Traditionally 5-MeO-DMT has been used in psychedelic snuff made from virola bark resin, and may be a trace constituent of ayahuasca when plants such as Diplopterys cabrerana are used as an admixture. 5-MeO-DMT is also found in the venom of the Colorado River toad (Bufo alvarius), although there is no direct evidence this was used as a hallucinogen until recent times.
Religious use 
5-MeO-DMT is a sacrament of the Church of the Tree of Life. From approximately 1971 to the late 1980s 5-MeO-DMT was discreetly available to members of the Church of the Tree of Life from Inner Center and after 1986 was also available to some other religious groups from Inner Center. Between 1970 and 1990 smoking of 5-MeO-DMT on parsley was probably one of the two most common forms of ingestion in the United States. A member of the Church of the Tree of Life estimates there were fewer than 6000 active members in 1979.
5-MeO-DMT is a methoxy analogue of DMT. Its pharmacological action is mainly through serotonin (5-HT) receptors. Specifically, this molecule shows high affinity for the 5-HT2 and 5-HT1A subtypes. Additional mechanisms of action such as inhibition of monoamine reuptake may be involved also.
Use and effects 
When used as a drug in its purified form, 5-MeO-DMT is smoked, insufflated, or injected and is active at a dose of as little as 2 mg. 5-MeO-DMT is also active orally, when taken with a MAOI, but according to numerous reports, the combination with MAOI is extremely unpleasant and has a strong body load. Additional mechanisms of action such as inhibition of MAOI may be involved also; According to the researcher Jonathan Ott, 5-MeO-DMT is active orally with doses over 30 mg without aid of an MAOI.
The onset of effects occurs within seconds after smoking/injecting, or minutes after insufflating, and the experience is sometimes described as similar to a near-death experience. Peak effects last for approximately 5–10 minutes when smoked. When insufflated, the peak effects are considerably less intense, but last for 15–25 minutes on average.
Although similar in many respects to its close relatives DMT and bufotenin (5-OH-DMT), the effects are typically not as visual. Some users report experiencing no visual effects from it even at very high doses.
Some report the effects to be unpleasant causing nausea and the feeling of being "sat on by an elephant".

US Federal Law 
On August 21, 2009, the Drug Enforcement Administration issued a Notice of Proposed Rulemaking to initiate placing 5-MeO-DMT into Schedule I of the Controlled Substances Act (the most restrictive category). Comment DEA-2009-0008-0007.1 requested a 180 day extension of the period for public comment and requests for hearings, objected to the proposed rule on multiple grounds including Constitutional issues, identified the submitter as a person who would be "adversely affected and aggrieved by the proposed ruling" and requested an exemption for religious use if DEA did place 5-MeO-DMT in Schedule I "as an attempt to define and clarify some legal issues."
On September 29 and 30, 2009, the DEA posted the Supporting & Related Materials for the NPRM while retaining the September 21, 2009 Due date for comments.
On October 28, 2009 DEA reopened the period for public comment because it had not posted two Supporting & Related Materials documents online during the original period for public comment. Documents and comments were split between Docket ID: DEA-2009-0008 and Docket ID: DEA-2009-0013 in a manner which creates difficulty and in viewing all documents and determining where and how to submit comments online. The two Supporting & Related Materials documents were not posted to Docket ID: DEA-2009-0013 until November 3, 2009 but the 30 day period for public comment was not changed from November 27, 2009.
5-MeO-DMT has been added to Schedule I, effective January 19, 2011. This means it is illegal to manufacture, buy, possess, or distribute (sell, trade or give) without a DEA license.
