What is pink cocaine?

Pink cocaine, also known as "tusi," has been connected to drug seizures and, in some cases, is being trafficked by the notorious Venezuelan migrant gang Tren de Argua, FOX 5 New York reported.

Multiple drug checking studies have found that the majority of tusi samples contain ketamine, often combined with methylenedioxymethamphetamine (MDMA), methamphetamine, cocaine, opioids, and/or new psychoactive substances, according to the National Library of Science

The bright-colored powder has been gaining popularity among the nightlife scene in New York City because of its low price and it is even being trafficked and sold in underground venues.

While the mystery powder is pink, narcotics experts tell FOX 5 New York that there is only a small amount (if any) of cocaine in it, and this makes it tough to determine what other drugs or chemicals are inside of it.
