G-Dragon tested negative in a thorough drug test by the National Forensic Service (NFS), local media reported Monday.
G-Dragon, the 35-year-old singer whose real name is Kwon Ji-yong, tested negative in a thorough screening of his hair conducted by the NFS, and the Incheon Police Station was recently notified of the results, according to media reports.
Results of the tests on his fingernails and toenails have not come back yet.
Police suspected that G-Dragon had shaved his body while trying to obtain samples of his hair, though the singer’s attorney denied it.
Nail tests have a detection period of up to six months and screen for a wider variety of drugs.
Hair tests have a detection period of up to a year, depending on the length of the hair sample taken. However, for those who dye and bleach their hair frequently, like G-Dragon, hair tests can be less effective.
