Speaking to one of my doctors many moons ago, there were apparently studies that showed that many alcoholics (of which I am a former - kept in check by my wife) were driven to alcoholism because we get a rush from alcohol in ways most people don't. Most people get the lack of inhibitions and then get tired, etc. given that it's a depressant.
However, people with a genetic history of psychedelic usage either through personal use or from parents/grandparents have a genetic disposition to getting a rush from the use of alcohol similar to using those drugs. We experience it almost like a stimulant.
My grandmother used psychedelics heavily in her youth and both my father and I have struggled with alcoholism.
Take what I say with a grain of salt - I haven't bothered doing research into it - just relaying what I once heard speaking with one of my former doctors. If true, it tracks from my personal experience.
That said, it's possible that it's why you and I are the way we are, yes. I also worry my kids will carry the same demons on their shoulders at some point but I've accepted that I can't stop that if it happens. I can only do what my parents did, and ensure that they know where and with whom they are safe so that if they go to battle with this demon, they can fight and win like I did.
I still drink, but my family keeps me safe.
