Cue-induced Craving for Marijuana in Cannabis Dependent Adults

Abstract

Recent interest in the development of medications for treatment of cannabis-use disorders indicates the need for laboratory models to evaluate potential compounds prior to undertaking clinical trials. To investigate whether a cue-reactivity paradigm could induce marijuana craving in cannabis dependent adults, 16 (eight female) cannabis dependent and 16 (eight female) cannabis-naïve participants were exposed to neutral and marijuana-related cues, and subsequent changes in mood, self-reported craving, and physiologic function were assessed. Significant group X cue interactions were found on all three VAS craving indices as well as on the Compulsivity scale of the Marijuana Craving Questionnaire-Brief Form (MCQ-BF). Cannabis dependent individuals responded to marijuana-related cues with significantly increased reports of marijuana craving compared to neutral cue exposure, although there were no cue-induced changes in any of the physiological measures. There were no significant gender differences on any of the measures. These results indicate that marijuana craving can be induced and assessed in cannabis dependent, healthy adults within a laboratory setting, and support the need for further research of the cue reactivity paradigm in the development of medications to treat cannabis-use disorders.
