Four types of drugs, including cocaine and ketamine, were found in Yoo Ah-in's possession, causing shock.
On the 1st, TV CHOSUN's News 9 reported that cocaine was also detected in Yoo Ah-in's possession and that he is expected to be summoned by the police soon.
According to News 9, Yoo Ah-in was found to have taken a total of four types of drugs including marijuana, propofol, cocaine, and ketamine.
Cocaine is a highly addictive central nervous system stimulant extracted from the coca plant leaf and is classified as one of the three major narcotics along with heroin and methamphetamine. Even a single use can cause changes in the nervous system.
Ketamine, which is also used as a general anesthetic, was classified as a narcotic in 2006 due to concerns of misuse.

The police plan to investigate whether Yoo Ah-in habitually took the drug by securing his ketamine prescription records during the hospital search and seizure process. In addition, they added that they plan to call Yoo Ah-in in as a suspect next week to investigate the circumstances of his drug use.
Recently, there have been allegations that Yoo Ah-in habitually used propofol. On the 5th of last month, the police seized and searched Yoo Ah-in's body as he returned to Korea from a trip to the United States via Incheon International Airport.
They conducted a urine test and also collected hair samples to analyze at the National Forensic Service (NFS). Unexpectedly, they discovered not only propofol, but also marijuana and a third type of narcotic, causing shock.
Meanwhile, Yoo Ah-in had promised to work hard this year with multiple projects such as the Netflix movie "The Match," the Netflix series "The Fool of the End," and the movie "High Five."
