No, but I'd be homeless (and I have been, albeit for a short time) right now and probably on something illegal if I didn't live where I do. Whether you call it an addiction or not I can't function (read: move) without opiates daily, and I get monthly injections as well. I have 12 different daily medications atm. Do you think I choose to live like this?
Before I got sick I was a respected special ed. teacher. Now I'm nothing. Life isn't as black and white as you seem to think it is. If I didn't have a caring wife and son there's no reason to think I would have any semblance of a life. Many are not lucky enough to have someone.
