The inherited or inborn risk for addiction based on family and twin studies is about 50 to 60% so this is for example based on studies showing that if you have a biological parent or grandparent addicted to alcohol you were at increased risk of getting addicted to alcohol than the general population even if raised outside of that Al alcohol using home right so these are really nicely carefully done studies so so high heritability is determined by twin concordance basically yeah and family studies right looking back in family trees looking at um kids who were adopted into non-alcohol using homes who developed alcohol use disorder at higher rates because they had a biological parent or grandparent so that those are those studies
