title: Gender differences in cocaine craving among non-treatment-seeking individuals with cocaine dependence.
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 estrogen-dopamine interactions and their effect on craving and mood.
