The new drug phenomenon over the past decade has been driven by the commodification of a wide range of psychoactive substances not controlled under drug laws, sold openly as 'legal highs', 'bath salts', or 'research chemicals' by entrepreneurs and criminal groups, especially via the Internet. In Europe, the rate of appearance of new psychoactive substances (NPS) averaged one new substance every 5–6 days, with 81 detected in 2013, 74 in 2012, 49 in 2011, and 41 in 2010. The number of Internet shops selling these substances rose from 170 in 2010 to 693 in 2012 and 651 in 2013. Many substances were originally synthesized years ago, some as failed pharmaceuticals, and their re-discovery has fueled the market.
