For the  people I know who are dealing with opioid addicition, it's their physicians.  Two are middle-aged women dealing with chronic conditions (lupus, rheumatoid arthritis) and another is a young man with a back injury whose doctors over-prescribed pain killers. These people were set on the road to addiction by the people they entrusted with their health.  Addiction is not a moral failing, but an increasingly likely outcome of the merger of our "health care" system and the pharmaceutical industry.
