Heroin overdose deaths across the country are spiking as a deadly new variant of the drug mixed with a powerful painkiller is spreading from New Hampshire to Washington State. The lethal combination of heroin and fentanyl, an opiate used to soothe the pain of cancer patients, is blamed for about 100 deaths from coast to coast. It is variously labelled as ‘bud ice,’ ‘income tax’ and ‘theraflu,’ authorities say. The hardest hit states in the epidemic are Maryland, with more than three dozen deaths since September, and Pennsylvania, with almost two dozen this month alone, according to reports.
