In May 2025, Sik-K was sentenced by the Seoul Western District Court to ten months in prison, with a two year suspension, for charges related to drug use. The court also ordered probation and 40 hours of drug relapse prevention education. According to prosecutors, the charges included the use of
ketamine and
ecstasy in October 2023, and the smoking and possession of
marijuana in January 2024. In April 2026, prosecutors appealed the first-trial sentence and again requested a prison sentence of three years and six months. His legal representatives asked the court to dismiss the appeal, citing his voluntary confession and stating that he had remained off drugs for two years. Following the first-trial sentence, Sik-K's scheduled appearance at
Waterbomb Seoul 2025 drew media attention because prosecutors had appealed the ruling and the case was remained ongoing. Waterbomb later stated that it planned to proceed with the appearance, while also saying that the decision could be reviewed depending on the appeal result and changes in public response. In April 2026, Sik-K appeared by video during
HAON's final-stage performance on
Show Me the Money 12, which aired on the same day as his first appeal hearing. == Awards and nominations ==
