The effects of drugs
New psychoactive substances (NPS) (often incorrectly called ‘legal highs’)
What are NPS?
NPS, such as mephedrone (meow meow) and spice, used to be available to buy legally in “head shops” (shops that sell drug paraphernalia) or online.
Since the Psychoactive Substances Act came into effect on May 26 2016 it has been illegal to supply any NPS in the UK for human consumption. This includes selling them or giving them away for free.
Alcohol, medicines, nicotine, caffeine and poppers (alkyl nitrites) are exempt from the act.
