The National Anti-Drug Agency (AADK) has replaced several staff members and initiated disciplinary proceedings following allegations that 47 clients at the Narcotics Addiction Rehabilitation Centre (Puspen) in Serdang, Kedah, tested positive for methamphetamine.

AADK director-general Ruslin Jusoh said the agency takes seriously the findings and report by the Enforcement Agency Integrity Commission (EAIC) on misconduct involving AADK personnel at the centre.
