hat is 2C-T-7?

2C-T-7 is a synthetic drug that produces hallucinogenic effects. Its chemical name is 2,5-dimethoxy-4- (n)-propylthiophenethylamine. 

2C-T-7 belongs to a class of chemical compounds known as phenethylamines. Many other phenethylamines also produce hallucinogenic effects, and several phenethylamines, including 2C-T-7, are Schedule I  Controlled Substances.


What does 2C-T-7 look like?

2C-T-7 typically is available as a powder, which may be packaged in small glass or plastic vials or in small, resealable plastic bags. 2C-T-7 powder often is placed into capsules. The powder occasionally is pressed into tablets, many of which are embossed with logos.

How is 2C-T-7 used?

2C-T-7 typically is consumed orally or is snorted; however, less common methods of administration include smoking the drug or inserting it into the rectum. 2C-T-7 generally is consumed orally in 10- to 30-milligram dosages, producing hallucinogenic effects that typically develop within 3 hours and last from 8 to 15 hours. 2-CT-7 powder usually is snorted at lower dosages, producing hallucinogenic effects that develop within 30 minutes and last from  4 to 8 hours.

Who abuses 2C-T-7?   

2C-T-7 typically is abused by teenagers and young adults. The drug often is used at raves, nightclubs, private parties, and other venues in which the use of club drugs, particularly MDMA (3,4-methylenedioxymethamphetamine, also known as ecstasy), is well-established. 


What are the risks?

2C-T-7 produces negative physical and psychological effects in users. Physical effects include visual and auditory disturbances and distortions, increased blood pressure, blurred vision, dehydration, dilated pupils, headaches, irregular heartbeat, jaw clenching, nausea, and vomiting. Psychological effects associated with the use of 2C-T-7 include emotional distress, hallucinations, inability to sleep, irritability, loss of memory, nervousness, restlessness, and tension. Additionally, 2C-T-7 can cause impaired judgment, leading abusers to engage in dangerous activities. 

Compounding these risks is the uncertainty of the 2C-T-7 dosage in a particular tablet, capsule, or quantity of powder--high dosages can cause overdoses and death. At least three deaths have been associated with 2C-T-7 abuse.

Is 2C-T-7 illegal?

Yes, 2C-T-7 is illegal. In March 2004 the Drug Enforcement Administration designated 2C-T-7 as a Schedule I substance under the Controlled Substances Act. Schedule I drugs, which include heroin and MDMA, have a high potential for abuse, serve no legitimate medical use in treatment in the United States, and have a lack of accepted medical safety for use under medical supervision.
