Transcranial Magnetic Stimulation to Help Heavy Cannabis Users See if They Use Less

Official title: Imaging the Effects of Intermittent Thetaburst Stimulation on Cannabis Self-Administration in Heavy Cannabis Users

Run by Duke University · NCT05401929 · Data updated 2026-11-12

This study tests whether a non-invasive brain stimulation method called iTBS can help heavy cannabis users reduce their use by changing brain responses to cannabis cues.

Is this trial a fit for you?

Likely a good fit

Adults ages 18-65 who currently use cannabis and can safely undergo brain stimulation procedures at a Duke/NIDA site.

Probably not a fit

Individuals with contraindications to brain stimulation or those who do not respond to this approach may not experience benefit.

What this trial studies

This interventional study uses left dorsolateral prefrontal cortex targeted iTBS to reduce neural reactivity to cannabis cues and lower cannabis use in adults aged 18-65 who currently use cannabis. It builds on prior data suggesting that enhancing cognitive control areas may dampen cue-driven craving and attention to drug cues. The protocol employs accelerated iTBS sessions to modulate brain circuits involved in salience and reward processing. The trial is conducted at Duke University Medical Center with NIDA collaboration, focusing on neuromodulation as a brain-based treatment option for cannabis use disorder. Participants must be cannabis users, meet safety criteria, and be able to complete all procedures.

Why it matters

Potential benefit: If successful, participants may experience reduced cannabis use and improved ability to manage cue-induced cravings.

How similar studies have gone: Prior studies and pilot data in brain stimulation for drug cues suggest potential benefits, but this exact approach in cannabis use is investigational.
