Chemistry:2C-T-9

From HandWiki

2C-T-9, also known as 4-tert-butylthio-2,5-dimethoxyphenethylamine, is a psychedelic drug of the phenethylamine and 2C families.[1][2][3] It is taken orally.[1][2]

Use and effects

According to Alexander Shulgin in his book PiHKAL (Phenethylamines I Have Known and Loved), the dose range of 2C-T-9 is 60 to 100 mg and its duration is 12 to 18 hours.[1][2][4] Its effects included impairment such that one would not feel comfortable to drive, more effects "to the body than to the head", "body energy", sleeping difficulties, and hangover.[1] The drug did not produce psychedelic visuals.[1] One of the reports of 2C-T-9 was rated as a '+++' on the Shulgin Rating Scale.[1]

Interactions

Pharmacology

Pharmacodynamics

2C-T-9 has been found to act as a serotonin 5-HT2A receptor agonist with modest potency (EC50 = 150 nM).[5] The drug failed to produce the head-twitch response, a behavioral proxy of psychedelic effects, in rodents at the assessed dose of 3 mg/kg, which was said to parallel its known low potency in humans.[5]

History

2C-T-9 was first described in the scientific literature by Alexander Shulgin and colleagues in 1991.[3][1] This included in a journal article[3] and in his book PiHKAL (Phenethylamines I Have Known and Loved).[1]

Society and culture

Canada

2C-T-9 is a controlled substance in Canada under phenethylamine blanket-ban language.[6]
