2C-T-7 is a psychedelic phenethylamine of the 2C family. In his book PiHKAL: A Chemical Love Story, Alexander Shulgin lists the dosage range as 10 to 30 mg. 2C-T-7 is generally taken orally, and produces psychedelic and entactogenic effects that last 8 to 15 hours. Up until Operation Web Tryp and three deaths, two of which involved the use of other drugs in addition to 2C-T-7, and one which involved an excessive insufflated dose, 2C-T-7 was sold commercially in Dutch and Japanese smartshops and online. It is known on the streets as Blue Mystic or 7th Heaven. There has been little real research done on this chemical other than Shulgin's comments in PiHKAL and a few small animal studies mostly aimed at detecting metabolites.

The mechanism that produces the psychedelic and entactogenic effects of 2C-T-7 is most likely to result from action as a 5-HT_2A serotonin receptor agonist in the brain, a mechanism of action shared by all of the hallucinogenic tryptamines and phenethylamines.

As the 2,5-desmethoxy derivative of 2C-T-7 has been shown to be a moderate monoamine oxidase A inhibitor, 2C-T-7 may likewise have MAO-A inhibitory effects. If 2C-T-7 does have MAO-A inhibitory effects, then this could indicate that 2C-T-7 is more likely to induce serotonin syndrome, especially at high dosages, than other serotonergic hallucinogens, which may contribute to the toxic effects of ephedrine and MDMA which have been shown to increase following MAO inhibition.
