VIENNA, Austria – June 2018: The NPS market continues to be dynamic as new substances emerge but a slower rate than in previous years. Some substances have established themselves on the drug market whilst others have disappeared after a short while. In 2016, 72 NPS were reported for the first time, a much smaller number than in 2015 (137 NPS). About 70 of the 130 NPS reported at the start of UNODC global monitoring in 2009 have since been reported every year to date. 60 NPS have not been reported since 2013 and may have disappeared from the market, although this is difficult to determine given the complexity of NPS identification in many parts of the world.
