2C-T-2 belongs to the 2C family and is a phenethylamine known for its psychedelic and entactogenic properties. This compound was initially synthesized by Alexander Shulgin in 1981 and earned its place among the “magical half-dozen” due to its significant role in the realm of psychedelic phenethylamines. 2C-T-2 shares similarities in both structure and pharmacodynamics with another compound, 2C-T-7, commonly referred to as “Blue Mystic.”

2C-T-2’s hallucinogenic and entheogenic effects are believed to be primarily attributed to its actions as an agonist on serotonin receptors, specifically the 5-HT2A, 5-HT2B, and 5-HT2C receptors. This mechanism of action is shared with other hallucinogenic compounds, including tryptamines and phenethylamines, albeit to varying degrees. Additionally, 2C-T-2 has been found to act as a partial agonist on adrenergic receptors.


The use of 2C-T-2, as well as other compounds in the 2C chemical series, carries a potential risk of neurotoxicity, affecting neurons containing serotonin and dopamine. This risk is further exacerbated when 2C series drugs are combined with substances such as alcohol, MDMA, and methamphetamine, particularly in serotonergic-containing cells.
Severe intoxication resulting from 2C series drug use may manifest as intense hallucinations, heightened agitation, aggressive behaviour, violence, dysphoria, elevated blood pressure, rapid heart rate (tachycardia), seizures, and increased body temperature (hyperthermia).

Drug prohibition laws

2C-T-2 is classified as a controlled substance in Argentina, along with 2C-B and 2C-I.
As of October 31, 2016, 2C-T-2 is a controlled substance listed under Schedule III in Canada.
2C-T-2 is designated as a controlled substance in China, effective as of October 2015.
The Netherlands holds the distinction of being the first country to prohibit and categorize 2C-T-2 as a hard drug through legislation. In April 1999, 2C-T-2 was included in List I of controlled substances under the Opium Law.
2C-T-2 is categorized as Schedule I in Sweden. It was initially labelled as a “health hazard” under the Act on the Prohibition of Certain Goods Dangerous to Health, commencing on April 1, 1999, per SFS 1999:58. This classification rendered it illegal to sell or possess.
Additionally, the Riksdag added 2C-T-2 to the Narcotic Drugs Punishments Act, classifying it under Swedish Schedule I, which pertains to substances, plant materials, and fungi that typically lack medical applications. This came into effect on March 16, 2004, as published by the Medical Products Agency (MPA) in regulation LVFS 2004:3, listing it as 2C-T-2, 2,5-dimethoxy-4-ethylthiophenethylamine.
United Kingdom
2C-T-2, along with all other compounds featured in PiHKAL, is illegal in the United Kingdom.
United States
In the United States, 2C-T-2 is explicitly classified as a Schedule I substance under SEC. 1152 of S.3187: Food and Drug Administration Safety and Innovation Act of 2012.
Australia designates 2C-T-2 as a Schedule 9 prohibited substance under the Poisons Standard, dated October 2015. A Schedule 9 substance is one prone to abuse or misuse, and its manufacture, possession, sale, or use is typically prohibited by law. Exceptions may apply for medical or scientific research, as well as for analytical, teaching, or training purposes, with approval from Commonwealth and State or Territory Health Authorities.
