SHANGHAI - Some crystal methamphetamine seized in a huge drug bust in China used the popular cold medicine Contac, manufactured by beleaguered British drugmaker GlaxoSmithKline (GSK), state media reported Tuesday.
The raid in the southern province of Guangdong, announced by state media last week, netted three tonnes of "crystal meth" in Lufeng city, said to account for one-third of China's production of the drug.
Some makers extracted pseudoephedrine from Contac, even employing students to empty the powder from the capsules as part of the process, the Global Times newspaper reported.
Chinese authorities have already put GSK under scrutiny over an alleged bribery case, detaining four executives of the British company last year.
GSK did not confirm the media report, but said it was concerned about any illegal use of its medicines.
