There have been a lot of people who got hooked on Oxy after being prescribed it for actual injuries.
The problem is once your prescription runs out the only alternative is HEROINE. A buddy's wife was prescribed it after getting injured in a car accident. It took her YEARS to get off it. Ruined their marriage and her life. She never had an addiction problem prior to that. She was a housewife/realtor. She was not even a big drinker.
IMHO, a lot of people do not start out intending to be drug addicts
For some (I imagine) it just gets a deep hold on them. I’m amazed, frankly, that some are able to break off from the hard stuff.
I never had any desire, thank God. Never tried it in any form.
However, I was in the hospital (unfortunately) decades and decades ago. I felt what the painkillers did to me - it was like a wild rollercoaster ride. I would have preferred the injury had not occurred obviously.
