The problem is multi-faceted, but often the doctor shopper was hooked by a trusted medical professional who sold out for the money, or didn’t follow the trends and problems that in retrospect seems pretty obvious. Kudos to the good docs who avoided this whole mess.
My dentist and I were speaking about this one day—he had torn an ACL or had some other knee issue, and his doc wrote some obscene amount of pills for pain. Can’t recall dosage but he got something like 25 pills in the prescription. He was stunned…and that was one script, one time long after I as a layman understood there was a problem. In the end, I we likely dealt with the tip of the iceberg worst offenders, and the finger being pointed at pharma gave offending physicians a finger to point away from themselves.
