June 2017 – UNODC World Drug Report 2017: Opioid market in a constant state of change

VIENNA, Austria – June 2017: The opioid market is becoming more diversified. This market comprises a combination of internationally controlled substances, particularly heroin, and prescription medicines that are either diverted from the legal market or produced as counterfeit medicines on a large scale. Some of these substances have remarkable pain-relieving properties and are widely used in human therapy; yet some are also liable to abuse and may produce dependence. The pills and powders containing synthetic opioids sold on the illicit market pose a threat to public health due to the variable quantity and potency of their active components, which in extreme cases, such as carfentanil, may be 10,000 times more potent than morphine. Such products can prove particularly dangerous when sold as street heroin or as counterfeit prescription drugs without the user’s knowledge. The emergence of highly toxic substances, as has been the case in the opioid market (e.g. the “fentanyl overdose crisis”), shows the need for increased regulation and monitoring.
