Deaths from new psychoactive substances (NPS) halve in 2017. (Published 6 August 2018).
There were 61 deaths from new psychoactive substances (NPS, or so-called "legal highs") in 2017, which equates to an age-standardised rate of 1.0 death per 1 million population. This is a statistically significant decrease from the 123 deaths in 2016 (2.1 per 1 million). The government introduced the Psychoactive Substances Act in 2016, which established a blanket ban on the importation, production or supply of most psychoactive substances not already covered by the law.
