A Bucks County woman named Jean, who’s been using heroin on and off for the last several years and who did not want to give her last name because of concerns about her privacy, said she saw a psychiatrist for anxiety five years ago who prescribed her Klonopin on her second visit. She didn’t tell her doctor she was using opioids at the time, she said, but it was immediately clear how powerful the two drugs were when used in combination.
