Sixty deaths linked to fentanyl drug in UK



Sixty people have died in the UK since December after it is believed they took the dangerous painkilling drug fentanyl, the National Crime Agency says.Best known as the drug that killed pop star Prince, fentanyl is 50 times more potent than heroin and up to 100 times more powerful than morphine.While it has been used in hospitals for decades as pain relief medication, an illegal version of the drug has caused so many deaths in the US in recent years that it has been described as a "weapon of mass destruction".But it is also becoming a widespread problem on the streets of Britain, claiming the lives of drug users unaware of its potency.
