2,5-Dimethoxy-4-methylamphetamine (DOM; known as STP, standing for "Serenity, Tranquility and Peace") is a psychedelic and a substituted amphetamine. It was first synthesized by Alexander Shulgin, and later reported in his book PiHKAL: A Chemical Love Story . DOM is classified as a Schedule I substance in the United States, and is similarly controlled in other parts of the world. Internationally, it is a Schedule I drug under the Convention on Psychotropic Substances. [2] It is generally taken orally.

Contents

History

STP was first synthesized and tested in 1963 by Alexander Shulgin, who was investigating the effect of 4-position substitutions on psychedelic amphetamines. [3]

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. This short-lived appearance of STP on the black market proved disastrous for several reasons. First, the tablets contained an excessively high dose of the chemical. 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. 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.

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. [4]

Pharmacology

DOM is a selective 5-HT2A, 5-HT2B, and 5-HT2C receptor partial agonist. 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. [5]

Analogues and derivatives

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 alpha-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 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. [6] [7]

Toxicity

Very little is known about the toxicity of DOM. 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. [4]

Canada

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

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.

Australia

DOM is schedule 9 under the Australia Poisons standard. [8] 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." [8]

United Kingdom

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

<span class="mw-page-title-main">2,5-Dimethoxy-4-iodoamphetamine</span> Chemical compound

2,5-Dimethoxy-4-iodoamphetamine (DOI) is a psychedelic drug and a substituted amphetamine. Unlike many other substituted amphetamines, however, it is not primarily a stimulant. DOI has a stereocenter and R-(−)-DOI is the more active stereoisomer. In neuroscience research, [125I]-R-(−)-DOI is used as a radioligand and indicator of the presence of 5-HT2A serotonin receptors. DOI's effects have been compared to LSD, although there are differences that experienced users can distinguish. Besides the longer duration, the trip tends to be more energetic than an LSD trip, with more body load and a different subjective visual experience. The after effects include residual stimulation and difficulty sleeping, which, depending on the dose, may persist for days. While rare, it is sometimes sold as a substitute for LSD, or even sold falsely as LSD, which may be dangerous because DOI does not have the same established safety profile as LSD.

2,5-Dimethoxy-4-butylamphetamine (DOBU) is a lesser-known psychedelic drug and a substituted amphetamine. DOBU was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), only low dosages of 2–3 mg were tested, with the duration simply listed as "very long". DOBU produces paresthesia and difficulty sleeping, but with few other effects. Compared to shorter chain homologues such as DOM, DOET and DOPR which are all potent hallucinogens, DOBU has an even stronger 5-HT2 binding affinity but fails to substitute for hallucinogens in animals or produce hallucinogenic effects in humans, suggesting it has low efficacy and is thus an antagonist or weak partial agonist at the 5-HT2A receptor.

<span class="mw-page-title-main">2,5-Dimethoxy-4-amylamphetamine</span> Chemical compound

Dimethoxy-4-amylamphetamine (DOAM) is a lesser-known psychedelic drug and a substituted amphetamine. DOAM was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the minimum dosage is listed as 10 mg, and the duration is unknown. DOAM produces a bare threshold and tenseness. As the 4-alkyl chain length is increased from shorter homologues such as DOM, DOET and DOPR which are all potent hallucinogens, the 5-HT2 binding affinity increases, rising to a maximum with the 4-(n-hexyl) derivative before falling again with even longer chains, but compounds with chain length longer than n-propyl, or with other bulky groups such as isopropyl, t-butyl or γ-phenylpropyl at the 4- position, fail to substitute for hallucinogens in animals or produce hallucinogenic effects in humans, suggesting these have low efficacy and are thus antagonists or partial agonists at the 5-HT2A receptor.

2,5-Dimethoxy-4-ethoxyamphetamine (MEM) is a psychedelic drug of the phenethylamine and amphetamine chemical classes. It was first synthesized by Alexander Shulgin. In his book PiHKAL, he lists the active dose range as 20–50 mg, and the duration as 10–14 hours. According to Shulgin, MEM produces color enhancement, visual phenomena, and pattern movement, among other effects.

Nichols as a non-neurotoxic MDMA analogue in 1991, and has subsequently been sold as a designer drug on the internet since the late 2000s (decade).

<span class="mw-page-title-main">2,5-Dimethoxy-4-fluoroamphetamine</span> Chemical compound

2,5-Dimethoxy-4-fluoroamphetamine (DOF) is a psychedelic drug of the phenethylamine and amphetamine classes. Alexander Shulgin briefly describes DOF in his book PiHKAL:

Animal studies that have compared DOF to the highly potent DOI and DOB imply that the human activity will be some four to six times less than these two heavier halide analogues.

DO<i>x</i> Class of chemical compounds

4-Substituted-2,5-dimethoxyamphetamines (DOx) is a chemical class of substituted amphetamine derivatives featuring methoxy groups at the 2- and 5- positions of the phenyl ring, and a substituent such as alkyl or halogen at the 4- position of the phenyl ring. Most compounds of this class are potent and long-lasting psychedelic drugs, and act as highly selective 5-HT2A, 5-HT2B, and 5-HT2C receptor partial agonists. A few bulkier derivatives such as DOAM have similarly high binding affinity for 5-HT2 receptors but instead act as antagonists, and so do not produce psychedelic effects though they retain amphetamine-like stimulant effects.
