PHILADELPHIA, July 22 (UPI) -- Prescription painkillers may be an important gateway to the use of injected illegal drugs such as heroin, U.S. researchers suggest.
Principal investigator Dr. Stephen Lankenau, an associate professor at Drexel University's School of Public Health, says young injection drug users' initiation into the misuse of opioid drugs were linked to a family history of drug misuse and having received prescriptions for opioid drugs in the past.
