Psychoactive substances act (United Kingdom 2016)

The Psychoactive Substances Act 2016 (PSA) is a controversial law in the United Kingdom intended to restrict the production, sale and supply of psychoactive substances. The bill was passed given Royal Assent on 28 January 2016, and came into force on 26 May 2016 across the entire United Kingdom. Legal scholars and human rights activists have criticized the legal PSA on legal and moral grounds and researchers have argued that the classification specified in the PSA is not evidence based and therefore scientifically invalid.
