'Highly toxic' drug on sale
ParaMethoxyMethylAmphetamine, or PMMA, has been found in tablets that look like ecstasy, as well as in some so-called legal highs.
The discovery was made after a series of raids. PMMA has been found in pink tablets with a Rolex Crown logo and white tablets with a four-leaf clover logo, as well as in some products claiming to be legal highs.
Detective Inspector Tommy Crombie, of the Scottish Crime and Drug Enforcement Agency, said: "Users may believe they have taken a weak ecstasy tablet when they have actually taken a tablet containing this highly toxic substance."
