Pandemic provides lessons in fighting opioid epidemic

NEW LONDON, CT - MARCH 23: A heroin user prepares to inject himself on March 23, 2016 in New London, CT. Communities nationwide are struggling with the unprecedented heroin and opioid pain pill epidemic. On March 15, the U.S. Centers for Disease Control (CDC), announced guidelines for doctors to reduce the amount of opioid painkillers prescribed nationwide, in an effort to curb the epidemic. The CDC estimates that most new heroin addicts first became hooked on prescription pain medication before graduating to heroin, which is stronger and cheaper. (Photo by John Moore/Getty Images)
