Evidence of an epidemic — fueled by cheap and easy access to powerful drugs, including painkillers prescribed by doctors — is evident throughout the Lehigh Valley. Fifty-nine people died of accidental overdoses involving heroin or other opiates in Northampton County in 2014 and 2015, a recent Morning Call review of coroner's records found. In Lehigh County, 40 people died over the same period. Another 76 died from overdoses that were tied to multiple drugs, though county Coroner Scott Grim would not provide details of the substances involved.
