If you’ve been thinking about cutting down or quitting, you may qualify for a confidential research study at Duke University that compensates for time and travel.
Researchers are investigating whether a non-medication intervention called repetitive Transcranial Magnetic Stimulation (rTMS) can help people reduce or stop marijuana use.
What is rTMS?
Repetitive transcranial magnetic stimulation (rTMS) uses magnetic coils to pulse magnetic waves on the brain. rTMS is a safe, non-invasive, FDA-cleared treatment for conditions like, Major Depressive Disorder (MDD), Obsessive-Compulsive Disorder (OCD), and Smoking Cessation. The use of rTMS is not FDA approved for the use of cannabis use disorder and is investigational in this study.
What will be involved?
• 11 Study visits over the course of 8 weeks
• Completing a daily survey about your current marijuana use
• 3 MRI brain scans
• 5 days of rTMS intervention spread across two weeks
• Surveys and questionnaires
Eligible participants may:
✓ Receive study-related intervention at no cost
✓ Receive counseling to support their goals
✓ Receive compensation for time and travel
You may qualify if you:
✓ Are 18–65 years old
