Evidence from family, twin and adoption studies indicates that genetic variation contributes to individual differences in risk for addiction to alcohol, tobacco and illicit drugs, and may contribute to comorbidity of addictions with other psychiatric disorders. Molecular genetic studies with animals and humans are helping to identify specific genes involved in drug-seeking behavior, which may improve understanding of the etiology of addictions and lead to new pharmacological treatments.
