Chief Superintendent Jeff Moore, Head of Neighbourhood and Partnerships, said: “Focused action has been taking place across Staffordshire with officers using stop and search powers to target those who they believe are connected in the use and supply.
“The Community Drug and Alcohol Service, commissioned by the Stoke-on-Trent City Council is also helping users to become more aware of the treatment facilities available and experts from Manchester Metropolitan University are helping to test and identify the substance so we can understand more about it.
“I would also like to thank the community for information they have passed to us so far and anyone that wants to report activity about the supply of drugs in their local area is asked to call 101.
“Alternatively, call Crimestoppers anonymously on 0800 555111.”
Cllr Ann James, Leader for Stoke-on-Trent City Council, said: “A huge amount of activity is underway across the council and our partners to support those who are impacted by use of the drug known locally as Monkey Dust.
“Ranging from outreach support to enforcement to improving pathways for treatment access, we are working together strategically and operationally to deliver support in the right way to those that need it.
“This is a new and complex issue and it’s really good to see all the pieces of the jigsaw, including today’s enforcement action, start to come together to have a major impact on stopping use of this drug in the city. Anyone who wants help locally should contact 01782 283113 for support.”
