Singer G-Dragon (Kwon Ji-yong) tested negative in a detailed hair drug examination. While the police have yet to secure conclusive evidence of drug use, they plan to continue investigating for other potential proof.

According to legal sources on November 20, G-Dragon, who was under investigation for drug-related charges under the Narcotics Control Act, received a negative result from a precise hair examination conducted by the National Forensic Service. However, the results of the nail examination are still pending.

During the suspect questioning on November 6, the police conducted a preliminary drug test on Kwon Ji-yong, which resulted in a negative reaction. Subsequently, additional hair and nail samples were collected and sent to the National Forensic Service for detailed analysis.

Hair samples can reveal drug use up to a year prior, depending on the length of the hair, while nail samples can provide information on drug use up to six months prior.

G-Dragon voluntarily appeared for questioning at the Nonhyeon Police Station, where the drug crime investigation office is located. His confident and relaxed demeanor during the investigation drew significant attention online.

In response to questions about the police's potentially excessive investigation, G-Dragon said, "I don't think it's excessive. It's not like the police and I have a grudge, and I believe they were just doing their job based on someone's statement. I came here to prove my innocence regarding drug crimes. I don't think it's excessive, but I wish they would push more positively. I hope they don't push further on unconfirmed matters."

In a subsequent exclusive interview with Yonhap News TV, G-Dragon once again denied drug allegations and addressed reports about his "full-body hair removal," stating, "It's completely different from the truth. I haven't bleached or dyed my hair for over a year and a half since my last album activities."

G-Dragon was previously investigated for marijuana smoking charges in 2011 but received a suspended indictment at that time.

A representative from the National Police Agency's National Investigation Headquarters (NIH) emphasized during a recent regular press briefing, "It's somewhat premature to conclude that the investigation is excessive just because the preliminary drug test was negative. Although it's challenging to conduct the investigation as this pre-charge investigative stage (internal investigation) became public, we will continue to investigate according to lawful procedures until we secure clear evidence."
