'''2C-I''', also known as '''2,5-dimethoxy-4-iodophenethylamine''', is a [[substituted phenethylamine|phenethylamine]] of the [[2C (psychedelics)|2C family]] with [[psychedelic drug|psychedelic]] effects.<ref>{{cite journal | vauthors = Bosak A, LoVecchio F, Levine M | title = Recurrent seizures and serotonin syndrome following "2C-I" ingestion | journal = Journal of Medical Toxicology | volume = 9 | issue = 2 | pages = 196–198 | date = June 2013 | pmid = 23378129 | pmc = 3657032 | doi = 10.1007/s13181-013-0287-x }}</ref> It was first [[chemical synthesis|synthesized]] by [[Alexander Shulgin]], and is described in Shulgin's book ''[[PiHKAL]]'' (1991).

The substance is consumed as a [[recreational drug]], and is circulated in the drug market in a powder form. 2C-I is sometimes confused with other related chemical substances such as [[25I-NBOMe|25I-NBOMe (2C-I-NBOMe)]], nicknamed "Smiles" and "N-bomb" in the media.<ref>{{cite web |title=25I-NBOMe (2C-I-NBOMe): Fatalities / Deaths |url=http://www.erowid.org/chemicals/2ci_nbome/2ci_nbome_death.shtml}}</ref><ref name="weiss">Weiss, Piper (September 20, 2012).
