“Do all prescription pain reducer users become heroin addicts?”
If they get addicted to opiate pain killers, then yes. Even one has never done heroin, if you become addicted to opiates, you are then addicted to any and all opiates you can get your hands on.
You avoided my question. Why?
I was prescribed painkillers for a back injury many years ago, and before it healed I experienced all the signs of physical addiction - increasing tolerance and withdrawl symptoms when I stopped taking it. I currently have a presciption for generic Vicodin for occasional flare-ups of IBS. I keep a couple in my desk drawer at work, and the rest are in the medicine cabinet at home. There's maybe 10 gone from a refill of 60 I got around the first of November.
