In a recent report, the International Narcotics Control Board said illegally operating internet pharmacies are acting as the supplier and dealer, for pharmaceuticals containing controlled substances, for which there is high demand by drug addicts.
Examples of these substances which are known to be increasingly abused and are sought after at illicit markets are hydrocodone and oxycodone, methadone, fentanyl, amphetamine and dexamfetamine, and methylphenidate.
The watchdog has called for a crackdown on the illegal trafficking, and urged governments to introduce more stringent legislation and to screen all routes of incoming and outgoing international mail.
