Tusi (tussi, tuci, tucibi), also known as pink cocaine, is a recreational drug that contains a mixture of different psychoactive substances, and is most commonly found in pink-dyed powder form.[1][2][3] The concoction is also referred to as “pink cocaine”, as it typically circulates on the illicit market in pink powder form.[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 (NPS).[2] Existing literatures suggest tusi to have no standard proportions of the constituent drugs.[1][2]

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.[2]
