Common questions

How does the UK's 2016 Act differ from older drug laws?+

Instead of listing specific banned drugs, the 2016 Act uses a catch-all approach. It prohibits any substance with psychoactive effects on the central nervous system, whether or not it appears on traditional drug schedules. This means new designer drugs are automatically illegal the moment they're created, rather than waiting for legislation to add them by name.

What activities does the law actually prohibit?+

The Act covers production, supply, distribution, import, and export. Any of these acts involving a psychoactive substance (except alcohol, tobacco, caffeine, food, and medicines) is prohibited. The breadth means even importing or supplying a novel compound for human consumption becomes a criminal offense.

Did the Act successfully reduce novel psychoactive substance markets?+

The Act had measurable impact. Head shops in the UK selling NPS fell from around 250 to approximately 12 within two years, suggesting the legislation disrupted retail distribution networks for these substances.
