Tusi or tusibí is a psychoactive substance of variable composition that has been mistakenly associated with 2C-B and called 'pink cocaine' in police and media reports. Its use has spread from Colombia to Latin America, Europe, and Spain, especially in recreational settings. Although overall prevalence is low, studies from 2020 to 2024 show notable consumption in specific populations, with annual prevalence of 15–20% among recreational substance users. Analysis of 470 samples reveals tusi mainly contains ketamine (93.2%) and MDMA (92.1%), with residual presence of 2C-B (3.6%) and cocaine (0.2%). Consumption is mostly intranasal and often combined with other substances like alcohol or MDMA, increasing risks.
