A blanket ban on the supply of legal highs from today has been welcomed by Derbyshire police chiefs.
The changes in the law mean it’s now an offence to sell or even give psychoactive substances to anyone for free, even to friends.
Superintendent Kem Mehmet said: “We welcome this act as it provides us with some clarity, and gives us the powers to tackle the supply of psychoactive substances.
"The psychoactive substances act will provide a blanket ban on the production, supply and importation of new psychoactive substances. This legislation will fundamentally change the way we tackle such substances.
"Members of the public have become frustrated by our lack of ability to close down shops that openly sell these products, which are the cause of a lot of anti-social and irrational behaviour and violence.
“We will now visit all shops that previously sold these substances to ensure that they are aware of the change in the law and to seize any stock that they have left.
“We would ask members of the public to tell us about any shops or people who continue to sell them after the new law comes into force.
“We will also be actively using the powers given to us to search people and seize substances.
“Our message to users remains the same – you never know what you are taking."
