The deaths of two men may be linked to the tablets Ecstasy tablets six times stronger than normal have been sold in the west of Scotland, according to police.
Detectives issued the warning after the deaths of two men in Ayrshire, which they believe are linked to the drug.
Strathclyde Police have made contact with health and social workers, as well as alcohol and drug action teams.
No direct connection has been established between the dead men and police are looking into how widely the tablets have been distributed.
The deaths are believed to have occurred several miles apart, in Prestwick and in the village of Patna.
Det Insp Craig McArthur, of Strathclyde Police, who is leading the investigation, said: “Our inquiries have revealed that they are extra strong.
“If that is the case then somebody could be popping a tablet and it could have the effect of taking six tablets.
“So in effect it is a lot, lot, stronger.”
