Yoo Ah In tests positive for cocaine and ketamine on top of propofol and marijuana

Yoo Ah In has now tested positive for cocaine and ketamine.

On March 1, TV Chosun reported Yoo Ah In's hair sample tested positive for cocaine and ketamine. The actor was previously investigated for the illegal use of propofol, and following a urine and hair test on February 5, he tested positive for both propofol and marijuana as well as an unknown substance.

The National Forensic Service then sent Yoo Ah In's hair sample to the Seoul Metropolitan Police Agency's drug investigation unit, where it reportedly tested positive for cocaine and ketamine. The police are currently investigating prescription records to find whether Yoo Ah In had been illegally using the drug habitually. He'll reportedly be called in for questioning as early as next week.
