Brief Summary:
This investigation seeks to better define the genetic basis for vulnerability to substance abuse.

Condition or disease Intervention/treatment
Substance Abuse Procedure: Blood draw

Detailed Description:

Dopamine (DA), a neurotransmitter helping to mediate reward and reinforcement, has been putatively linked to the development of substance abuse, alcohol abuse, and alcoholism. Identification of specific vulnerability-association alleles for receptors, other molecules within the reward mediating system, and other genes that may predispose individuals to the development of such disorders is the goal of the study.

This investigation will help elucidate the genetic underpinnings of substance abuse, potentially leading to the improved methods to diagnose those at risk and to help develop better therapeutic interventions.
