Abstract excerpt

RATIONALE: Vulnerability to drug abuse disorders is determined not only by environmental but also by genetic factors. A body of evidence suggests that endogenous opioid peptide systems may influence rewarding effects of addictive substances, and thus, their individual expression levels may contribute to drug abuse liability. OBJECTIVES: The aim of our study was to assess whether basal genotype-dependent brain...
