2C-I is a psychedelic drug and phenethylamine of the 2C family. It was developed and popularized by Alexander Shulgin. It was described in Shulgin’s book "PiHKAL (Phenethylamines i Have Known And Loved)". The drug is used recreationally and as an entheogen but no medical or industrial uses have been reported yet. It is mostly commonly encountered in the form of its hydrochloride salt, a fluffy, sparkling white powder, and has also been pressed into tablet form.

Recreational use

In the early 2000s, 2C-I was sold in Dutch smart shops, after 2C-B - which was previously sold - was banned. In April 2003, 2C-I was also banned in the Netherlands, along with 3 other 2C-x phenethylamines previously sold in Dutch smartshops for short periods of time. During the same period, 2C-I also became available in powder form from several online vendors of research chemicals in the United States, Asia, and Western-Europe. In 2002 and 2003, tablets of 2C-I were being sold in nightclubs and at raves in Denmark and in the United Kingdom as a club drug. 2C-I is often referred to as SlippyBitz.Fact|date=October 2007.


2C-I is generally taken orally, although it can also be insufflated, or administered rectally as well (though 2C-I often causes considerable pain upon insufflation). There have also been a few reports of intramuscular and intravenous injections. An oral recreational dose of 2C-I is commonly between 10mg and 25mg, although doses as low as 2mg have been reported to be active. The onset of effects usually occurs within an hour, and the effects of the drug typically last somewhere in the range of 5 to 12 hours. The effects of the drug are often described as quite similar to those of its chemical relative 2C-B, combining psychedelic or hallucinogenic effects typical of drugs such as LSD with the empathogenic or entactogenic effects of drugs such as MDMA (ecstasy). Some users report that the effects are more mental and less sensory than those of 2C-B. The feelings have been known to resemble that of childhood blissFact|date=January 2008. Users of 2C-I do, however, tend to report a physical stimulant effect, often quite strong and cleanFact|date=January 2008. Although unpleasant physical side effects such as muscle tension, nausea, and vomiting have been reported, their incidence in the use of 2C-I appears to be less common than in the use of some of the other closely related phenethylamines such as 2C-T-2 and 2C-T-7.

Side effects

Virtually no research has been conducted on the toxicity of 2C-I. No deaths have been attributed to the drug and several large doses (100+ milligrams) have been survived. There have been no reports of physical dependence or addiction. Comparisons with similar compounds suggest that use of 2C-I is unlikely to result in physical dependence.


2C-I is an illegal, controlled substance in several European nations, including Denmark, Germany, Greece, Ireland, the Netherlands, Poland, Spain and the United Kingdom.In December 2003, the European Council issued a binding order compelling all EU member states to ban 2C-I within three months. 2C-I is unscheduled and unregulated in the United States, however its close similarity in structure and effects to 2C-B could potentially subject possession and sale of 2C-I to prosecution under the Federal Analog Act, if it is intended for human consumption. This seems to be the tactic the federal government is taking in the wake of the DEA's Operation Web Tryp.
