4-HO-DET, also known as 4-hydroxy-diethyl-tryptamine, CZ-74, is a hallucinogenic drug and psychedelic compound of moderate duration. 4-HO-DET is a substituted tryptamine, structurally related to psilocin, ethocybin, and 4-HO-DIPT.
4-HO-DET received the lab code CZ-74 in the late 1950s by the inventors of the substance, Albert Hofmann and Franz Troxler. The substance was used together with its phosphoryloxy-analog ethocybin in human clinical trials in the 1960s by the German researchers Hanscarl Leuner and G. Baer.
Sveriges riksdags health ministry Statens folkhälsoinstitut classified 4-HO-DET as "health hazard" under the act Lagen om förbud mot vissa hälsofarliga varor (translated Act on the Prohibition of Certain Goods Dangerous to Health) as of Nov 1, 2005, in their regulation SFS 2005:733 listed as 4-hydroxi-N,N-diethyltryptamin (4-HO-DET), making it illegal to sell or possess.
