I’m no expert but I’ve read on it a lot. In one larger study, 85% of alcoholics carried the genetic marker for alcoholism (15% didn’t). So, basically if you carry the genes, you are more likely to develop alcoholism. Doesn’t mean you will though. Just more likely.
To me this is a separate issue than taking ownership. I was born with a propensity for high blood pressure. That doesn’t make it my fault, but it does make it my responsibility to control.
It’s like carrying boiling water. You don’t have to get burned, it do it often enough and you probably will.
