Neuroimaging of Adolescent Cannabis Use Treatment
This study is looking at how brain activity related to learning might help predict how well teens respond to a treatment program for cannabis use. It involves teens aged 14-17 who have used cannabis. Participants will have a brain scan and then take part in 10 weekly online sessions using a method called Contingency Management (a behavioral therapy where you can earn prizes for staying cannabis-free). The study wants to see if brain activity measured at the beginning can tell us who will do well in the treatment. The main goals are to see how often cannabis is used after treatment and to measure scores on a test called the Cannabis Use Disorder Identification Test (CUDIT) at the start of the study. The current recruitment status is unclear.
- Study design
- This is an interventional study planning to enroll 80 participants. It is not specified if it is randomized or blinded.
- What's involved
- You would have a phone prescreening, two in-person visits (one for consent and eligibility, one for an fMRI brain scan), and then ten weekly virtual sessions over 13 weeks. You will also provide urine samples for drug testing at home.
- Compensation
- Not stated in the trial record.
- Follow-up
- Your cannabis use frequency will be measured 2-4 weeks after your last Contingency Management visit.

What this trial measures
- Cannabis use frequencyScreening and Post-Intervention Follow-Up Visit (2-4 weeks after last CM visit)
The investigators will measure cannabis use frequency via percent of days where cannabis was used over the past 30 days via the Timeline Followback Scale (Sobell and Sobell, 1992)
- Cannabis Use Disorder Identification Test (CUDIT) ScoreBaseline
The CUDIT (Adamson et al., 2010) is a measure of cannabis use disorder symptom level. This scale is an 8-item scale that asks about cannabis use disorder symptoms over the past year and is scored on a scale of 0 (no cannabis use in the past year) to 32 (daily cannabis use, physical and psychological dependence symptoms, severe cannabis misuse). The CUDIT will be measured once at the baseline screening visit.
