Your "if you're in pain, just suck it up" attitude shows zero compassion for those in pain. Oh, I'm not saying that there are those who have minor aches and pains who run to their local Dr Feelgood for an oxycontin prescription. But there are people who need these drugs because they are in real pain.

I suspect that there is a significant difference between your experience of combat and mine -- I would believe that you were never wounded. I was, twice. The second time was from a nasty antipersonnel device called a claymore mine (see https://en.wikipedia.org/wiki/M18_Claymore_mine if you're not familiar with it). It hurts. It hurts a lot. In the hospital, I spent days largely in a morphine-induced haze, and craving more when I came out of it. I didn't become addicted, I needed it for the pain. I am certain that if you had the same experience, you would not have made your comment.
