Hair tests to detect addiction
The government plans to have a full-scale hair drug-testing service in the fourth quarter after launching a pilot scheme yesterday. Commissioner for Narcotics Sally Wong said tests can detect commonly abused drugs such as cannabis, cocaine, Ecstasy, Ice, ketamine and also cough syrup. Results are normally available in three days. Wong said while urinalysis was convenient and fast, hair drug-testing could detect drug abuse that has been going on from a few weeks to up to a few months.
