Gender/Sex & CUD Remission

November 6, 2025 updated by: Medical University of South Carolina

Gender and Sex Hormone Influences on Cannabis Use Disorder Remission

Adults (ages 18+) who would like to reduce their cannabis use (N=224) will be enrolled in an 8-week treatment program. All participants will receive counseling (1 goals session with a therapist followed by 7 weekly computerized cognitive-behavioral therapy sessions). Detailed cannabis assessments (biological and self-report) will be conducted throughout treatment and at 1-, 2-, and 3-months post-treatment completion. Daily electronic diaries will be administered via text message to record detailed logs of cannabis use quantity and frequency. Salivary samples will be collected (and video observed) daily throughout treatment to analyze for progesterone.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Other: Cognitive Behavioral Therapy - Men
112 participants identifying as men will be enrolled in 8 weeks of behavioral treatment for cannabis use disorder (CUD). They will receive a motivational interviewing session with a therapist followed by 7 weekly online modules of CBT4CBT with continued monitoring and support from a therapist. Gender and hormonal factors will be examined as predictors of CUD remission and cannabis outcomes.
Behavioral: Cognitive Behavioral Therapy (CBT4CBT)
Participants will receive one therapist-led motivational interviewing/goal setting session followed by 7 sessions of computerized CBT4CBT.
Other: Cognitive Behavioral Therapy - Women
112 participants identifying as women will be enrolled in 8 weeks of behavioral treatment for CUD. They will receive a motivational interviewing session with a therapist followed by 7 weekly online modules of CBT4CBT with continued monitoring and support from a therapist. Gender and hormonal factors will be examined as predictors of CUD remission and cannabis outcomes.
Behavioral: Cognitive Behavioral Therapy (CBT4CBT)
Participants will receive one therapist-led motivational interviewing/goal setting session followed by 7 sessions of computerized CBT4CBT.

Plan for Individual participant data (IPD)

Plan to Share Individual Participant Data (IPD)?

YES

IPD Plan Description

Investigators support data sharing as essential for scientific advancement. It is expected that primary outcome papers will be completed and submitted to appropriate peer-reviewed scientific journals within 180 days of data lock. Requests for data from this project by individuals outside of the research team will be reviewed by the team following data lock. Data sharing will adhere to all provisions of the Health Insurance Portability and Accountability Act (HIPAA) and the rights and privacy of people who participate in research will be protected at all times. The requesting Investigator must specify the subset of variables needed or provide a detailed justification of why the complete dataset is absolutely necessary. Data made available to other investigators will be free of identifiers that would permit linkages to individual research participants and variables that could lead to deductive disclosure of the identity of individual subjects.
