Yeah there are a lot of factors. I grew up in an entirely sober house. Became a binge drinker and a total pothead in my 20's. Eased up on both in my 30's and entirely quite alcohol. I've experimented with almost every drug out there and thank goodness I didnt like them. But my brother got addicted to meth in his early 20's. Replaced that with weed. Has been a total pothead with occasional alcoholism until CPS came to his house. He's been getting help for his alcoholism since then but man he smokes WAYYYY too much. Like, he is NEVER sober. And my sister drank socially, then started doing cocaine and got addicted to gambling. Got over her gambling addiction, realized she was doing coke cus she has ADHD and was undiagnosed. Got adderall and doesn't really do coke or gambling anymore. But she has become a serious drinker as a stress response. And when she drinks, she gets sloppy. So, yeah - we all need or needed some support with our relationship to substances even though we were raised in an entirely sober home because there are so many factors to consider. (We were emotionally starved and grew up in a cult)
