When a Seoul court sentenced K-pop superstar T.O.P to 10 months in prison, suspended for 2 years, for marijuana use last week, the catchy hook by the rapper and his Big Bang bandmate G-Dragon likely popped up in the minds of many fans.
The 29-year-old may not have actually been "high" when he wrote the lyrics for the popular tune, but the public has been casting a suspicious eye on the duo nonetheless, especially given G-Dragon's previous run-in with authorities over alleged marijuana use.
The Big Bang leader in 2011 admitted to marijuana use at a Japanese club in 2011, although he claimed he was unaware of the substance he was inhaling at the time.
Drug use and the controversy that ensues have been an abiding presence in the entertainment business, like the bad hangover that follows a bachelor party.
It dates all the way back to the "Godfather of Korean rock" Shin Jung-hyeon in the 1970s, when he was arrested for marijuana use.
Shortly thereafter, singing legend Cho Yong-pil was also slapped with a fine for smoking pot. Bombarded with criticism and ridicule, the superstar singer announced his retirement -- although he returned less than a year later.
Another Korean pop icon, Lee Seung-chul, was embroiled in a drug scandal in 1989.
The singer said he decided to quit drugs for good after he was humiliated by being strip-searched at a jail cell.
Even global pop-sensation Psy -- who set the world on fire with "Gangnam Style" in 2012 -- was caught smoking marijuana in 2001, a few months after his debut.
For the most part, the public shows knee-jerk reaction to celebrities' drug use and the stars lie low thereafter. Drug use here remains a taboo and can deal a severe blow to celebrities' careers.
Singer Hyun Jin-young, who was found guilty of methamphetamine use in 1993, mounted several attempts to return to the entertainment scene, but without much success.
