What is DOB, DOM, DOC, DOI

DOB (4-bromo-2,5-dimethoxyamphetamine) or Bromine — DMA-psychedelic phenylethylamine class. Chemical formula (C11H16BrNO2).
DOM (2,5-dimethoxy-4-methylamphetamine) or STP — a chemical compound of the class of amphetamines, hallucinogen. DOM action is associated with agonism to serotonin receptors of type 5-HT2A.Chemical formula (C12H19NO2).
DOC (2,5-dimethoxy-4-chloroamphetamine) or Dr. chemical compound from the class of amphetamines, psychedelic effect which resembles the effect of LSD. Chemical formula (C11H16ClNO2).
DOI (2,5-dimethoxy-4-iodoamphetamine) is a chemical compound of the class of amphetamines. Psychedelic, an agonist of 5-HT2A receptors. Chemical formula (C11H18INO2).

All of these chemical compounds are synthetic amphetamines, namely 4-substituted 2,5-dimethoxyamphetamine. All of them were discovered by Alexander Shulgin and described in the book PiHKAL (Phenethylamines I Have Known and Loved). In this Quartet, a list of highly fenilatilamina in PiHKAL ends. In addition, there are connections such as DOET, DOPR, DOEF. However, such exotic can not be found in free circulation.

All of them are characterized by a long and exhausting action (from 14 to 30 hours), small dosages (0.5-10 mg) and "amphetamine" side effects (lack of sleep, tremors, jaw spasms, the appearance of obsessive ideas.).

DOB, DOM, DOC and DOI are not uncommon on the black market, as well, very often sold in the form of stamps (rectangular pieces of cardboard with a picture) under the guise of LSD or mescaline, and in the form of tablets under the guise of extasy, although in themselves are much cheaper. TO*-the group has a more noticeable bitter taste unlike LSD. Many users also note that compared with LSD they act more "rigidly."

The main damaging effect of this class of drugs associated with serotoninergicheskim action, ie changes neurotransmission of the brain. Usually wakes sleeping schizophrenia, depression or bipolar disorder. There is information that high doses of substances can provoke vasoconstriction of the limb vessels, which can lead to gangrene. Also, the use should be excluded for people with circulatory problems, heart disease, liver or kidney disease, glaucoma, epilepsy. There are reports of the development of cyanosis of the skin in healthy people when using doses of drugs from 3 mg.

From the history of Dimethoxyamphetamine:
1963 year-Alexander Shulgin invents DOM and puts the first experiments on itself.
1967 year some unknown enterprising chemist released DOM on the street, where he was called STP, which meant, as they said, Serenity, Tranquility, Peace (Serenity, Tranquility, Peace). Also DOM was deciphered as Super Terrific Psychedelic (the most Terrible Psychedelic), or Stop the Police (Stop the Police). Police called him Too Stupid to Puke (Too Dumb to Puke). In fact, the name was taken from the shortening of the name of the additive to motor oil, which has absolutely no chemical relation to this substance.
1967-DOB was first synthesized by Alexander Shulgin.
1971 - published a report on the synthesis of DOB and its unprecedented high activity. Several hundred deaths related to overdose of drugs have been recorded in the history of DOB, DOM, DOC and DOI.
All these substances are now listed in Schedule I of the Convention on psychotropic substances (English). Convention on Psychotropic Substances).
