New psychoactive substances (including "legal highs"). (Published 3 September 2015)
The number of deaths involving NPS are low compared with the number of deaths involving heroin/morphine, other opiates, or cocaine. However, over the past few years there has been an rise in NPS deaths, with 82 deaths registered in 2014 (up from 63 deaths in 2013). Analysis of the trends based on the year the death occurred, reveal a different pattern than that seen for registration year. Analysis of year of occurrence suggests that there were sharp increases in NPS deaths between 2010 and 2011 and again between 2011 and 2012, but then the number of deaths fell in 2013. Although figures for deaths occurring in 2014 are very incomplete, initial indications suggest that the upward trend in NPS deaths has now stabilised.
