The purpose of this study is to investigate natural reward processing in cannabis users. Natural reward processing refers to how a person responds to enjoyable or stimulating non-drug experiences. Two groups will participate in the study: 1) people who use cannabis, and 2) people who do not use cannabis. The study will use personalized scripted imagery which involves developing and listening to a detailed story about a personal experience. Scripted imagery has been used to investigate responses to stress and drug experiences and will be used in this study to investigate responses to naturally rewarding experiences.
This study will evaluate the effect of counseling plus Approach Bias Modification on cannabis use and craving in people with cannabis use disorder. The study consists of a screening visit, four treatment visits and two follow-up visits. Participants will have 3 sessions of counseling, 4 sessions of Approach Bias Modification, and 3 cue reactivity sessions.
