A two-time Blue Dragon Award winner and once considered the undisputed face of Korean cinema, Yoo Ah-in, whose real name is Eom Hong-sik, saw his celebrated career collapse after authorities uncovered a secret pattern of drug use that spanned years. Between September 2020 and March 2022, the South Korean actor visited numerous private cosmetic clinics in Seoul, where medical staff administered approximately 9. 6 liters of propofol, along with midazolam, ketamine, and remimazolam, across about 181 separate clinic visits. Despite official warnings from doctors about the serious health risks of excessive anesthesia, the actor continued seeking these powerful substances for treatment of severe depression and chronic sleep disorders.
To maintain his growing dependency outside clinical settings, Yoo exploited gaps in South Korea’s prescription tracking system. From May 2021 until August 2023, he systematically obtained around 1,100 illegal sleeping pills, specifically Stilnox and Xanax, through 44 separate transactions. He circumvented federal regulations by fraudulently using the personal identity details of third parties, including family members and close acquaintances. The situation escalated during a trip to Los Angeles in January 2023, accompanied by a close companion identified as Choi.
While in the United States, Yoo used marijuana with his inner circle. Tensions rose when a visiting blogger and YouTube user witnessed the drug use firsthand. Prosecutors later alleged that Yoo pressured the witness to also smoke marijuana, effectively making the witness complicit to ensure silence. Investigators further claimed that the actor and Choi intimidated the witness and coerced him to leave Korea immediately while demanding he withdraw any potential statements to law enforcement.
The unraveling began when the Ministry of Food and Drug Safety conducted an automated audit of prescription databases. The government system flagged an abnormally high volume of medical anesthetics linked to Yoo, far exceeding standard clinical limits, and quietly reported the findings to the Seoul Metropolitan Police Agency. On February 5, 2023, law enforcement intercepted Yoo at Incheon International Airport immediately after his flight from Los Angeles landed. Authorities imposed an immediate travel ban and collected physical samples for forensic analysis.
Subsequent tests by the National Forensic Service returned positive results for controlled substances including propofol, marijuana, ketamine, and cocaine. Within days of his airport detention, police raided several dermatology and cosmetic clinics in Seoul’s affluent Gangnam and Gucheon districts to seize medical records and arrest assisting doctors. The rapid public revelation of his years-long secret drug use triggered a massive legal battle and marked the sudden collapse of a decorated film career. The immediate media shock following his airport detention sent catastrophic ripple effects through South Korea’s entertainment and commercial sectors.
Major global platforms like Netflix immediately cut ties, excluding the award-winning actor from the second season of “Hellbound” and replacing him with actor Kim Sung-cheol. Completed film projects faced indefinite paralysis, disrupting studio release schedules entirely. These works included the big-budget sports drama “The Match” starring Lee Byung-hun, the disaster sci-fi series “Goodbye Earth,” and the fantasy film “High-5. ”
Instead of canceling projects outright, production companies were forced to carefully edit the actor’s scenes, apply visual treatments to conceal his presence, or postpone distribution indefinitely.
Beyond production sites, major fashion houses, beauty lines, and retail conglomerates terminated lucrative sponsorship contracts, and billion-won lawsuits were filed to recover financial damages from breach of morality clauses. As formal indictments advanced in late 2023, the legal battle moved to the Seoul Central District Court, where prosecutors presented a comprehensive charge sheet carrying a potential sentence of up to four years in prison. Prosecutors vigorously pursued charges including chronic drug use, purchasing drugs through third parties, smoking marijuana abroad, evidence tampering, and witness intimidation. During the high-stakes trial proceedings, clear legal contradictions emerged regarding the actor’s actual criminal responsibility.
While the defense readily acknowledged his chronic medical dependency on propofol and essentially admitted to marijuana use, they strongly challenged the remaining felony charges. Defense attorneys argued that the actor suffered from severe depression, panic disorders, and chronic insomnia, making him susceptible to excessive anesthesia, while strongly denying allegations of inducing others to destroy evidence or forcing companions to smoke marijuana in California. The legal drama escalated into public uproar when unexpected sexual assault allegations surfaced on national news channels midway through the trial. Investigators from Seoul’s Yongsan Police Station opened an inquiry into claims that the actor sexually assaulted a 30-year-old male victim inside an apartment in central Seoul.
The shocking news dominated entertainment headlines immediately, creating a sharp wave of public anger. However, after thorough forensic reviews, multiple witness interrogations, and analysis of surveillance footage, police officially dropped all charges due to a complete lack of supporting evidence. Drug tests conducted during the assault investigation also came back negative, leading authorities to close the case without referring it to prosecutors. The judicial proceedings simultaneously cast a harsh light on systemic corruption within South Korea’s private medical sector, revealing how licensed doctors enabled access to illicit drugs.
Prosecutors launched parallel investigations targeting cosmetic dermatologists and plastic surgeons who provided large quantities of propofol, ketamine, and midazolam without proper clinical justification. Courts found that many medical professionals deliberately falsified patient treatment records, failed to register official prescriptions in federal monitoring systems, and prioritized financial gain over professional ethics. Judges imposed significant financial penalties and suspended prison sentences on several treating physicians, including a 40 million won fine on one prominent doctor who repeatedly administered illegal doses. On September 3, 2024, the Seoul Central District Court issued its historic ruling, convicting the actor of habitual medical drug use and illegal proxy purchases.
The judges stated that the actor committed these crimes while completely disregarding federal drug regulations and showed serious recklessness regarding controlled substances. The court sentenced him to one year in prison, imposed a 2 million won fine, ordered additional financial forfeiture, and executed an immediate arrest and detention order. Substantively, the court acquitted the actor of evidence tampering and witness intimidation charges, citing insufficient conclusive evidence to prove beyond reasonable doubt that he intimidated the visiting YouTuber into smoking marijuana or deleted messages. The former star was led from the courtroom in handcuffs to serve his sentence, witnessing his prestigious career receive its final blow.
Following the initial conviction and immediate imprisonment, the legal path took a dramatic turn during appeal proceedings at the Seoul High Court in February 2025. After the actor spent more than five months in detention, the appellate panel overturned the immediate prison sentence. The appeals judge issued a one-year prison term suspended for two years, along with a 2 million won fine, allowing his immediate release. In mitigating the sentence, the court affirmed that his excessive use of medical drugs stemmed primarily from severe depression and chronic sleep disorders rather than recreational motives.
The panel noted his sincere remorse, his record free of prior criminal convictions, and the fact that he actively sought medical treatment to overcome his addiction during detention. Prosecutors quickly appealed the reduced sentence, demanding a four-year prison term. But on July 3, 2025, South Korea’s Supreme Court formally rejected the prosecution’s appeal and confirmed the suspended sentence as final. Following the confirmation of his sentence, major structural changes began behind closed doors concerning the actor’s professional representation and business management.
By mid-2026, Yoo officially ended his decade-long exclusive contract with United Artists Agency, marking a complete end to his long professional partnership. This separation immediately triggered intense media speculation within the entertainment industry about his next strategic moves. Unconfirmed industry reports claimed he entered high-stakes contract negotiations with prominent entertainment entities, including Galaxy Corporation, with media alleging billion-won signing deals. Despite management representatives quickly asserting that no binding agreements had been reached, the public leak suggested an organized framework working diligently to secure his long-term financial support and manage his professional rehabilitation.
Yoo made a calculated return to the public eye in July 2026 by attending a high-profile industry event, igniting widespread debate throughout South Korea. He arrived at the special premiere of the feature film “Hope” alongside director Jang Jae-hyun, the acclaimed filmmaker behind the successful movie “Exuma. ” This appearance marked his first official public outing in front of press cameras and industry executives since his release from detention, prompting immediate and intensive media coverage. The appearance coincided with strong film industry rumors suggesting that Jang Jae-hyun was considering the actor for the lead role in his upcoming project titled “Vampire.
” Despite production representatives urging public caution and insisting that casting decisions had not been finalized, industry analysts viewed his appearance at a major press event as a deliberate step to gauge market reaction and test public acceptance of his potential acting return. Despite the resolution of his legal status, the entire case remains highly controversial, revealing sharp cultural divisions over accountability, celebrity privilege, and rehabilitation in South Korea. Critics and civic groups express widespread public anger over the judicial outcome, arguing that the suspended sentence for more than 100 instances of illegal drug use highlights systematic double standards that favor wealthy, prominent figures who can afford elite legal defense teams. Many commentators point to the inherent contradiction in an industry that imposes strict lifetime bans on lesser-known artists while simultaneously facilitating rapid returns for profitable top-tier stars.
Conversely, supporters and legal advocates maintain that his punishment aligns with judicial precedents, emphasizing that his medical addiction required clinical rehabilitation rather than extended imprisonment. Ultimately, the fall of Yoo and his partial legal reprieve serves as a stark case study on the intersection of fame, mental health, systemic medical oversight, and public ethics. The scandal exposed structural gaps in federal drug tracking, led to severe financial losses for production studios, and resulted in legal penalties for the medical professionals who enabled it. While the courts have formally closed his criminal file with a final probationary period, the court of public opinion remains deeply divided.
With rumors continuing to circulate about new film roles and agency contracts in Seoul, the fundamental question of whether a fallen cultural icon can truly rebuild his career in South Korean society remains one of the most controversial topics in modern Asian entertainment history.
