Summary

The purpose of this study is to explore sex differences in cognitive functioning and responses to marijuana-related items, and to determine whether stress impacts these measures.

Hypothesis 1: Attentional bias will be greater for marijuana cues in male marijuana-dependent subjects relative to female marijuana-dependent or non-dependent male controls.

Hypothesis 2: Marijuana-dependent females will exhibit greater stress-induced changes in attentional bias and cognitive functioning than marijuana-dependent males.

Conditions

  • Marijuana Dependence

Interventions

OTHER

Cognitive stressor

The Paced Auditory Serial Addition Task (PASAT-C), has been modified for use as a computerized laboratory-based stressor. Single digits are presented, and the patient must add each new digit to the one immediately prior to it and click on the appropriate answer. Failure to do so in the allotted time results in a noxious error sound.
