Abstract
The purpose of this pilot study was to evaluate potential gender differences in cocaine craving among non–treatment seekers with cocaine dependence. We examined 10 female and 11 male individuals matched by demographic characteristics and severity of drug use; we used a multidimensional questionnaire that assesses various aspects of craving: (a) current intensity, (b) projected intensity, (c) resistance to use cocaine, (d) responsiveness to drug-related conditioned stimuli, and (e) imagined likelihood of use if in a setting with access to drugs. Other instruments utilized were the Hamilton Rating Scale for Depression and Addiction Severity Index. Female subjects had higher total craving scores (p <. 05), with post hoc tests showing more present desire to use cocaine and responsivity to drug-conditioned stimuli, along with lower scores on the desire not to use cocaine. In exploratory analyses, we found greater depressive symptomatology (p =. 02) and severity of family/social problems (p =. 02) in females than their males counterparts. These results suggest that gender may influence different aspects of cocaine craving. As estrogen is purported to modulate craving-related dopaminergic systems, further studies will be needed to confirm these observed gender differences and to investigate their possible mechanisms, particularly estrogendopamine interactions and their effect on craving and mood.
