Inherited vulnerability matters, but exposure, development, relationships and opportunity shape whether vulnerability becomes harm.
Alcohol Addiction: Why Genes Matter — And Why They Never Tell the Whole Story
Alcohol-use disorder has a substantial heritable component, but environment, exposure, age and social context remain central to whether and how problems develop.
