On the subject of addicts being able to quit...
I realize that everyone is different, but people do make the choice to quit using things they're physically addicted to; this is proven because people *have* made those choices. From cigarettes (which I gave up) to heroin and everything in between. Some people may find it much more difficult than others, I don't dispute that. Some may never be able to bring themselves to choose to quit, but they still possess the choice. Can they choose to quit? Yes. Will they? That is a different question.
I do not take the position that people who choose not to quit are weak or bad people or simply lack willpower or whatever. I do not disparage them or make light of the difficulty of the choice. But I also do not simply shrug and say "Well, some people can't quit." Yes, they can. They choose not to, for a variety of reasons, and for some of them, it may seem very much as if they cannot make that choice to quit. But while they still draw breath and are conscious, they can.
There are people who have died from the effects of withdrawal. The recent death of that pop singer might have been one such case. That does not mean she did not have the ability to make the choice to quit; it does mean that quitting may have killed her, which is a very different thing.
Anything that is physically possible for me to do, I can choose to do. That doesn't mean I *will* choose to do it, but I do have the option. I cannot become an astronaut or a professional baseball player. But I can lose weight, I can get in shape, I can quit smoking (did that years ago), I can stop drinking alcohol (did that when I was diagnosed with diabetes), and if I were a user of illicit drugs, I could choose to quit using them. That choice might mean getting help from outside if I could not manage to do it on my own; but the choice would be mine to make - or to not make.
People who are addicted to illicit drugs are victims in many ways. Many of them have very tragic backgrounds and life histories that make me have great sympathy for them and their circumstances. I cannot say that were I in their shoes, I would not have ended up just like them. But they choose to continue to abuse drugs; or to quit if they want to take that step. Hard? Yes. Possible? Also yes.
What I have learned about is something that makes more sense to me; something I believe is termed a 'live choice'. That is, a choice that a person both can make and might make. In other words, an addict can choose to quit using drugs; but many will not do so in practice. If you bring it up to them, they reject it as an option. It's not that they cannot quit, it's that they will not make that choice under any circumstances. The choice is not a 'live choice' to them because it seems not possible in their world, in their circumstances. It still does not mean that they have no choice.
