safer for doctors to practice medicine. kieran, here's the real problem. you met dr. green in my story help he says it's difficult to tell if someone's an addict. say a patient comes into his clinic. the only thing he can ask them is how much pain are you in and he expects them to tell you the truth. i'll share a quick story for you. he prescribed pain medication for a 79-year-old bm who lived in a nursing home and she had a broken leg so he figured she must be in pain so she started dealing the drugs from the nursing home. you just never know. >> a lot of the kids we talked to in our story, their parents, grandparents other people had these market narcotic prescriptions. some kid never went through a gateway drug or marijuana. he tried three vicodin tablets at a party and he was hooked. >> sadly, this woman in the nursing home was selling to kids
