2C-T-2, or 2,5-dimethoxy-4-ethylthiophenethylamine is a psychedelic and entactogenic phenethylamine of the 2C family. It was first synthesized in 1981 by Alexander Shulgin.[1] The drug has structural and pharmacodynamic properties similar to the drug 2C-T-7 ('Blue Mystic').

In Alexander Shulgin's book PiHKAL, the dosage range is listed as 12 to 25 mg. According to Erowid a threshold dose would be 5 mg, a light dose would range from 8–15 mg, a common dose is 15–22 mg and a strong dose would be considered to be 20–40 mg.


Effects are similar to the related 2C-T-7, but 2C-T-2 is said to produce more of a body load and other reactions which can be unpleasant, reported effects being reddening of the face and warm flushes. It can also be very nauseating while coming up, some users report a period of restlessness during the come up and feeling cold. There have been no reported deaths from 2C-T-2, unlike 2C-T-7, and the psychedelic effects have been much milder. The onset usually starts after an hour of ingestion and rises for about two hours until the user hits the plateau. Insufflated doses reach a peak much faster and have been compared to the effect of ketamine on the body.

Hallucinations similar to those created by LSD and other serotonergic psychedelics are very prominent on typical 2C-T-2 doses. The trip is often described as being similar to LSD due to the serotonergic effects and hallucinations. Some users describe "beautiful" visuals, similar to 2C-T-7, which has coined its street name "Rosy". In some aspects the effect is similar to other phenethylamines like MDMA (users sometimes have euphoric rushes); however, unlike MDMA, 2C-T-2 is a strong psychedelic, and its effects can be unpredictable, even for "experienced" users.

2C-T-2 can be just as powerful as LSD and other hallucinogens. Due to the particular body load effect of this substance it is significantly different than most popular hallucinogens though its capability to produce a bad trip is still present. Effects can last up to 16 hours from dosing.


The mechanism of action that produces 2C-T-2’s hallucinogenic and entheogenic effects has not been specifically established, however it is most likely to result from action as a 5-HT2A serotonin receptor agonist in the brain, a mechanism of action shared by all of the hallucinogenic tryptamines and phenethylamines for which the mechanism of action is known.

2C-T-2 also known to act as a selective monoamine oxidase A inhibitor, like other phenethylamines substituted with an alkylthio group at the 4 position such as 2C-T-7 and 4-MTA.


There are no known reports of neurotoxicity, but very little scientific knowledge exists for 2C-T-2.

It may be expected that at higher doses it would display similar toxicity to that of other phenethylamines of the 2C-T family, due to the additional MAOI effects, which can lead to the potentially lethal serotonin syndrome when combined with stimulant drugs.

All confirmed fatalities involving 2C-T drugs involve high dosages taken by the nasal route, or dangerous combinations with stimulant and depressant drugs such as Alcohol, MDMA and Cocaine.

It is also dangerous for a person who takes certain kinds of anti-depressant medications such as serotonin reuptake inhibitors to ingest 2C-T-2 due to the risk of serotonin syndrome.

Drug prohibition laws


2C-T-2 is also a controlled substance in Argentina as well as 2C-B and 2C-I.[2]
