2,5-Dimethoxy-4-methylamphetamine (DOM), also known as STP (standing for "Serenity, Tranquility, and Peace" and/or other phrases), is a psychedelic drug of the phenethylamine, amphetamine, and DOx families. [3] [4] [1] [5] [6] It is generally taken orally. [4] [1] [5]

Contents

DOM was first synthesized by Alexander Shulgin, and later described in his book PiHKAL: A Chemical Love Story (1991). [1] It is classified as a Schedule I controlled substance in the United States, and is similarly controlled in other parts of the world. [1] Internationally, it is a Schedule I drug under the Convention on Psychotropic Substances. [7]

Effects

Effects of this drug include substantial perceptual changes such as blurred vision, multiple images, vibration of objects, visual alterations, distorted shapes, enhancement of details, slowed passage of time, increased sexual drive and pleasure, and increased contrasts. It may cause mystical experiences and changes in consciousness. It may also cause pupillary dilation and a rise in systolic blood pressure. [8]

The effects of DOM were assessed in clinical studies in the late 1960s and early 1970s. [6] [9] [10] [11]

Side effects

Very little is known about the toxicity of DOM.

DOM acts as a selective 5-HT2A, 5-HT2B, and 5-HT2C receptor full agonist. [15] [14] [16] In one study, its affinities (Ki) were 12 nM for the serotonin 5-HT2A Its psychedelic effects are mediated by its agonistic properties at the 5-HT2A receptor. Due to its selectivity, DOM is often used in scientific research when studying the 5-HT2 receptor subfamily. DOM is a chiral molecule, and R-(−)-DOM is the more active enantiomer, functioning as a potent agonist of the serotonin 5-HT family of receptors, mainly of the 5-HT2 subtype. [23]

The drug is inactive as a human trace amine-associated receptor 1 (TAAR1) agonist but is an agonist of the rhesus monkey TAAR1. [18] DOM is inactive as a monoamine reuptake inhibitor and releasing agent. [17] It is a very weak monoamine oxidase inhibitor (MAOI), specifically of monoamine oxidase A (MAO-A), whereas it was inactive at monoamine oxidase B (MAO-B). [21] [22]

Effects

In contrast to amphetamines like (–)-cathinone but similarly to mescaline, DOM has shown no stimulant-like or reinforcing effects in rhesus monkeys. [24] [25] [26] [27] Conversely however, DOC has shown reinforcing effects, including conditioned place preference (CPP) and self-administration, in rodents similarly to methamphetamine. [28] This is analogous to other findings in which various 2C and NBOMe drugs have been found to produce dopaminergic elevations and reinforcing effects in rodents. [29] [30] [31] [32] [33] [34] [35]

Pharmacokinetics

According to Alexander Shulgin, the effects of DOM typically last 14 to 20 hours, though other clinical trials indicate a duration of 7 to 8 hours. [8]

Chemistry

DOM, also known as 2,5-dimethoxy-4-methylamphetamine or as 2,5-dimethoxy-4-methyl-α-methylphenethylamine, is a substituted phenethylamine and amphetamine and is a member of the DOx group of drugs. [3] [4] [5] [6] It is structurally related to the naturally occurring phenethylamine psychedelic mescaline (3,4,5-trimethoxyphenethylamine). [6] [36] Analogues of DOM include other DOx drugs such as DOET, DOB, DOI, DOC, and TMA, among others. [6] The α-desmethyl or phenethylamine analogue of DOM is 2C-D. [3] [4] Ariadne is the α-ethyl or phenylisobutylamine analogue of DOM. [37] [4]

Chemical structures of some DOM variants

The 2,6-dimethoxy positional isomer of DOM, known as Ψ-DOM, is also mentioned in PiHKAL as being active, as is the α-ethyl homologue Ariadne. Analogues where the methoxy groups at the 2,5- positions of the aromatic ring have been altered have also been synthesised and tested as part of an effort to identify the binding mode of DOM at the serotonin 5-HT2A receptor. Both the 2- and 5- O-desmethyl derivatives 2-DM-DOM and 5-DM-DOM, and the 2- and 5- ethyl analogues 2-Et-DOM and 5-Et-DOM, have been tested, but in all cases were significantly less potent than the corresponding methoxy compound, showing the importance of the oxygen lone pairs in 5-HT2A binding. [38] [39]

History

STP was first synthesized and tested in 1963 by Alexander Shulgin, who was investigating the effect of 4-position substitutions on psychedelic amphetamines. [1] [4]

In mid-1967, tablets containing 20 mg (later 10 mg) of STP were widely distributed in the Haight-Ashbury District of San Francisco under the name of STP, having been manufactured by underground chemists Owsley Stanley and Tim Scully. [1] This short-lived appearance of STP on the black market proved disastrous for several reasons. [1] First, the tablets contained an excessively high dose of the chemical. [1] This, combined with DOM's slow onset of action (which encouraged some users, familiar with drugs that have quicker onsets, such as LSD, to re-dose) and its remarkably long duration, caused many users to panic and sent some to the emergency room. [1] Second, treatment of such overdoses was complicated by the fact that no one at the time knew that the tablets called STP were, in fact, DOM, and there was no effective antidote. [1]

Society and culture

Australia

DOM is schedule 9 under the Australia Poisons standard. [40] A schedule 9 substance is a "Substances which may be abused or misused, the manufacture, possession, sale or use of which should be prohibited by law except when required for medical or scientific research, or for analytical, teaching or training purposes with approval of Commonwealth and/or State or Territory Health Authorities." [40]

Canada

Listed as a Schedule 1, as it is an analogue of amphetamine.

United Kingdom

DOM is a Class A drug in the United Kingdom under the Misuse of Drugs Act 1971.

United States

DOM is Schedule I in the United States. This means it is illegal to manufacture, buy, possess, or distribute (make, trade, own or give) without a DEA license.

Despite the reasonably constant recreational use of hallucinogens since at least the early 1970s [44], the reinforcing effects of hallucinogens have not been widely investigated in laboratory animals. Indeed, one of the earliest studies on the reinforcing effects of drugs using the intravenous self-administration procedure in rhesus monkeys found that no animal initiated self-injection of mescaline either spontaneously or after one month of programmed administration [45]. Likewise, the phenethylamine hallucinogen 2,5-dimethoxy-4-methylamphetamine (DOM) was not effective in maintaining self-administration in rhesus monkeys [46]. Nevertheless, the hallucinogen-like phenethylamine 3,4-methylenedioxymethamphetamine (MDMA) has been shown to act as a reinforcer in intravenous self-administration paradigms in baboons [47], rhesus monkeys [48 – 50], rats [51] and mice [52].

One of the earliest studies on the reinforcing effects of drugs using the intravenous self-administration procedure in rhesus monkeys found that no animal initiated self-injection of mescaline either spontaneously or after one month of programmed administration, [...] (Deneau et al., 1969). The lack of mescaline self-administration stood in contrast to positive findings of self-administration of morphine, codeine, cocaine, amphetamine, pentobarbital, ethanol, and caffeine. A subsequent study with rhesus monkeys using 2,5-dimethoxy-4-methylamphetamine (DOM; Yanagita, 1986) provided similar results as the mescaline study. These findings have withstood the test of time, as the primary literature is virtually devoid of any accounts of self-administration of [classical hallucinogens (CH)], suggesting that there are very limited conditions under which laboratory animals voluntarily consume CH.

Shulgin, who synthesized hundreds of novel hallucinogenic tryptamines and phenylethylamines in his home laboratory. He described the synthesis of these compounds and also their psychotomimetic effects experienced in self-experiments in detail in his books PIHKAL and TIHKAL (199, 200). He created several dimethoxy-substituted phenylethylamines, such as DOM, 2,5-dimethoxy-4-bromoamphetamine (DOB), 2,5-dimethoxy-4-iodoamphetamine (DOI), and 2,5-dimethoxy-4-ethylamphetamine (DOET), which all display strong hallucinogenic properties. These drugs usually have much longer durations of action (12–30 h) and are much more potent agonists at 5-HT2A-Rs (50- to 175-fold) compared to their related phenylethylamine derivative mescaline (duration of action: 4–8 h) (189, 199, 200).
