POLICE are warning drug users in Wrexham and surrounding areas of a possible contaminated batch of (NPS) mamba.

The synthetic cannabis is believed to be in circulation following reports of serious medical episodes amongst users, officers have said.

Superintendent Nick Evans explained: “This batch may be highly dangerous and we advise in the strongest terms that anyone in possession of this substance should not take it and instead dispose of it safely.

“We advise all dependent drug users to get support from local drug services and urge anyone feeling unwell having taken this substance to seek urgent medical assistance.”
