Abstract excerpt

Genetic factors play a role in the vulnerability to cocaine dependence. The reinforcing properties of cocaine are related to the dopaminergic system, and, in particular, the dopamine receptors have been linked to the reward mechanisms. The present study examines the role of the variants TaqI A of the dopamine D2 receptor gene and BalI of the dopamine D3 receptor gene in a Brazilian sample consisting of 730...
