New psychoactive substance group

Source: United Nations Office on Drugs and Crime, The Challenge of New Psychoactive Substances (Vienna, March 2013). a Based on information from 42 countries. Respondents were asked to provide information on a yearly basis on observed seizure trends (“increasing”, “stable”, “decreasing”) for the above-mentioned NPS groups. When the number of respondents reporting “increasing” trends exceeded the number of respondents reporting “declining” or “stable” trends, an overall increase is shown in the table. Similarly, when the number of reported “declining” trends exceeded the “increasing” or “stable” trends an overall decline is shown. Where the largest number of respondents reported “stable” trends, an overall stable trend is shown. != Increasing, "= Decreasing, # = Stable, $ unknown.

The most closely monitored region with regard to the emergence of NPS so far has been Europe, notably the European Union. EMCDDA, in cooperation with Europol, created the European early warning system for NPS. Whenever a NPS is detected in a country, information on its manufacture, trafficking and use is sent by the State to Europol and EMCDDA. The early warning system comprises the 27 European Union countries, as well as Norway and the two European Union candidate countries, Croatia and Turkey. Through the early warning system, a total of 236 substances were identified over the period 2005-2012, equivalent to more than 90 per cent of all substances found

2005

Among Internet searches for the chemical groups of the main NPS, the strongest interest by far has been in synthetic cannabinoids, i.e. the main psychoactive substances contained in Spice. This has clearly increased over the period 2008-2012. Interest in piperazines started to emerge at the global level as of 2008 and peaked in 2009 before declining in subsequent years. Interest in phenethylamines remained relatively constant. Interest in tryptamines, in contrast, appears to have lost momentum in recent years. Interest in synthetic cathinones increased in 2010, and again in 2012, to the extent that it was higher than for the other NPS groups in that year, except the synthetic cannabinoids.
