Can you tell me are adult children of an alcoholic more prone to become alcoholics then the general public?

Yes: And for many reasons. Being raised in an alcoholic household can increase stress and anxiety, and promote use of alcohol as a coping strategy in children as they grow older. In addition, there are genetic influences even if the person is not raised in their home of origin. It does not mean that an adult child of an alcoholic is destined to have alcoholism, but does increase the risks, esp. In men.
