Yes it is interesting and most probably helpful to think about what the roots are to your addiction, i.e. what caused it from the beginning. However, once you have an addiction, the biochemistry in the brain has changed and suddenly the addiction is a separate problem in its own that we need to focus on, regardless the roots that made it grow from the beginning. For instance, some people start to use drugs because they are depressed, so the root of their addiction is their depression. But they can cure their depression and still be left with their addiction, so just getting rid of the roots of the problem don't always help.
