Drug deaths link to 'purer' heroin

Police in Glasgow have linked the deaths of three addicts in less than 12 hours with supplies of unusually pure heroin. Officers believe seven addicts have died in this way in the last week.

A similar spate of deaths occurred in Bristol in January, when up to eight people died of drug overdoses after heroin up to 80 per cent pure, rather than the usual 40 per cent, was found to be circulating.
