Big difference in getting addicted as the result of pain medication following an unsucessful surgery and using coke/crystal to pack your nose to get high.

Not really.
Taking drugs to feel better vs. taking drugs to feel better.

But rarely do you find people who buy coke/crack/heroin to help their backpain....or any pain for that matter. Most who do drugs and get hooked originally did it for the fun of it, thinking it was no big deal -- that they could easily quit.
