The Role of Family History. Addiction is due 50 percent to genetic predisposition and 50 percent to poor coping skills. This has been confirmed by numerous studies. One study looked at 861 identical twin pairs and 653 fraternal (non-identical) twin pairs. When one identical twin was addicted to alcohol, the other twin had a high probability of being addicted. But when one non-identical twin was addicted to alcohol, the other twin did not necessarily have an addiction. Based on the differences between the identical and non-identical twins, the study showed 50-60 percent of addiction is due to genetic factors.(1) Those numbers have been confirmed by other studies.(2) The other 50 percent is due to poor coping skills, such as dealing with stress or uncomfortable emotions.
