No trauma here either. My parents were far from perfect but they loved me, mostly gave me what I needed to the best of their abilities, no abuse, and yet I still turned to drugs and alcohol at 15 and much later became an alcohol addict. Addiction seems to be a biochemical condition, and while childhood issues certainly can lead us to drink to excess so that addiction has the opportunity to bloom, I'm not sure there's any solid evidence that addiction itself is related to how we were raised.
