A new police crackdown on the use and supply of drugs in Chesterfield has led to 11 arrests so far.
Operation Pheonix was launched to tackle the distribution of all drugs in the town, but particularly MCAT.
Insp John Roddis said: “The use of MCAT is becoming more and more popular across the county. The users of the drug are being linked to and involved in violent crime and acquisitive crime which includes car crime and burglaries.”
Steve Holme, drugs manager for the force, said: “The users of MCAT can develop erratic behaviour causing them to become anxious and paranoid.
“It is important to remind people buying drugs that it is a fact of the drug markets that what you think you are buying isn’t always what you get.”
