Abstract:
This study uses data from the National Longitudinal Study of Adolescent Health to examine whether a polymorphism in the serotonin transporter gene (SHTTLPR) moderates the effects of marijuana use on property offending. The results reveal that 5HTTLPR interacts with marijuana use to predict significantly higher levels of property offending for African American females. The interaction coefficient is not statistically significant for Caucasian males, African American males, or Caucasian females. These findings suggest that marijuana use is associated only with higher levels of property offending among African American females who carry one or more copies of the 5HTTLPR short allele.
