Pink cocaine, also known as 'tusi,' is gaining notoriety as a dangerous party drug in the U.S. and U.K., particularly in nightlife scenes such as New York and South Florida. Despite its name, it typically does not contain cocaine but is a mix of substances like ketamine, MDMA, methamphetamine, and sometimes opioids like fentanyl, making its effects highly unpredictable and risky. Authorities first noted its presence in New York City in early 2023, with its use linked to tragic incidents, including the death of former One Direction member Liam Payne. The drug's appeal lies in its vibrant color and marketing as a designer drug, but its inconsistent composition means users are often unaware of what they are consuming. Drug dealers exploit this allure by selling it at high prices, despite its dangerous and unpredictable nature. The spread and varied composition of pink cocaine highlight the challenges in combating new drug trends and ensuring public safety.
