Liam Payne had 'pink cocaine' in system, autopsy shows

Dr. Peter Chin-Hong joins LiveNOW's Austin Westfall to explain what "pink cocaine" is after an autopsy revealed that the recreational drug was in Liam Payne's system at the time of his death.

A drug is reportedly being connected to former One Direction singer Liam Payne and music mogul Sean "Diddy" Combs. 

Payne, who died after falling from a hotel balcony on Oct. 16 in Buenos Aires, Argentina, had a partial autopsy performed on his body and toxicology test results determined he had several substances in his body, including pink cocaine, according to a new report from ABC News.

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.
