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 form known as pink cocaine.[1][2][3] Tusi is believed to have originated in Latin America around 2018.[4] Drug-checking studies in Latin America report tusi to be a concoction of ketamine, MDMA, cocaine, methamphetamine, caffeine, opioids, and other new psychoactive substances.[2] Existing literature suggests there is no standard proportioning of the constituent drugs in tusi.[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]
Society and culture
[edit]In United States
[edit]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 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]
