Does abuse during childhood correlate/lead to substance abuse or addiction?

I’m doing a psych research project on this subject and I’m in need of some help. With addiction I was thinking of possibly covering sex addiction or addiction to work as a topic.(Victims occupy themselves with things to avoid the real problem?) Personal opinions, stories, or experiences with this subject would even be helpful. Do they take drugs b/c many drugs provide dopamine, making the victim happy? Or just a coincidence? Anything you can provide is useful. Thanks!
