Korean prosecutors on Wednesday formally charged four female celebrities, Park Si-yeon, Jang Mi-inae, Lee Seung-yeun and Hyun Young, with abusing propofol, a drug widely used as an anesthetic during surgery, reported Korean media.
Prosecutors said Park was the heaviest user of the four, receiving more than 180 injections of the drug at two cosmetic surgery clinics between 2011 and 2012, for surgical procedures that did not actually take place.
The authorities have also charged the doctors who illegally administered the propofol injections, and an artiste management agency representative who had obstructed their investigations.
Propofol is a fast-acting sedative which relaxes the user and gives the user a feeling of euphoria.
However, it has a number of side effects, and can affect the user’s respiratory and cardiac functions.
Propofol is the same drug that killed US superstar Michael Jackson, who died from an overdose in 2009.
