Contextualization and personality wrt addiction are major factors though. I had morphine for for extreme pains as I had my appendix blow out and my whole abdomen was a cesspool for a few weeks in hospital. I never had withdrawal nor addiction symptoms as the experience was confined to hospital. I am lucky to have a personality type that can easily externalize addiction. Basically for me it is like flipping a switch, or confining the feelings to certain contexts. Even so, I can easily see how people do get addicted beyond their control, so I would never say it is 'easy' to 'just stop'.
