Tusi (drug)

Tusi (tuci, tucibi, pink cocaine), is a recreational drug most commonly found in pink-dyed powder form that contains a mixture of different psychoactive substances. The concoction is also referred to as “pink cocaine”, as it typically circulates on the illicit market in pink powder form. Tusi is believed to have originated in Latin America around 2018. Drug-checking studies in Latin America report tusi to be a typical concoction of ketamine, MDMA, methamphetamine, cocaine, caffeine, opioids, and other new psychoactive substances (NPS). Existing literatures suggest tuci to have no standard proportions of the constituent drugs.

The name "tusi" phonetically translates to "2C", while they may be pronounced in a similar way, tuci is not the same psychoactive substance as 2C-B (or, more broadly, the 2C family). Tuci, according to the UN Office on Drugs and Crime, contained no 2C-B in most instances as of 2022.
