psychoactive substances
The Psychoactive Substances Act 2016 prohibits (subject to exempted activities, such as those relating to healthcare) the producing, supplying, offering to supply, importing, or exporting of a “psychoactive substance”. A “psychoactive substance” is defined as any substance that is (a) likely to be consumed by individuals for its psychoactive effect and (b) not an exempted substance (chiefly controlled drugs, medicinal products, alcohol, tobacco, and caffeine). The effect of the Act is to prohibit so-called “legal highs”.
