Dopamine receptor (D4) polymorphism is related to comorbidity between marijuana abuse and depression.

Addictive behaviors - 1 Oct 2013

Bobadilla Leonardo, Vaske Jamie, Asberg Kia

Abstract excerpt

The rates of marijuana abuse are steadily increasing in the U.S. Data suggest that comorbid marijuana abuse and depression is associated with worse outcomes than either diagnosis. Genetic studies independently link the DRD4 gene polymorphism to substance use and to internalizing disorders, but no study has examined whether the DRD4 polymorphism is linked to comorbid marijuana use and depression in a population...
