Tusi (also written as tussi,tuci, or tucibi) is a recreational drug that contains a mixture of different psychoactive substances, most commonly found in a pink-dyed powder known as pink cocaine. [1] [2] [3] It is believed to have originated in Latin America around 2018. [4] Ketamine and MDMA are the most common ingredients, although cocaine, methamphetamine, oxycodone, caffeine, cathinones, and other designer drugs are found as well. [2] There is no standard proportions of the constituent drugs. [1] [2]
Though the name "tusi" is phonetically similar to "2C", tusi is not the same psychoactive substance as 2C-B or more broadly, the 2C family. Tusi, according to the UN Office on Drugs and Crime, contained no 2C-B in most instances as of 2022. [2] It may have been named this way because the drug has effects crudely similar to the psychedelic 2C-B.[ citation needed ]
Authorities in New York City report that lab-tested samples have very little or no cocaine. They say there are record numbers of overdoses and there is no way to know exactly what is in pink cocaine. [5] Because the drug usually contains a mix of uppers and downers, it is sometimes called a speedball. [6]
Authorities[ which? ] are trying to educate potential users who may not know how different ketamine is from cocaine. Cocaine is a stimulant and ketamine is a sedative-hallucinogenic anesthetic. [7] It does not mix well with alcohol. [8]
