Zapping the brain to break the cannabis habit
NCT ID NCT05401929
First seen Jun 27, 2026 · Last updated Jul 14, 2026 · Updated 2 times
Summary
This study tests whether a non-invasive brain stimulation technique called TMS can reduce attention to cannabis cues and help heavy users cut down. Fifty near-daily cannabis users will receive either real or placebo TMS over five days, then be followed for four weeks. The goal is to see if TMS lowers brain responses to cannabis triggers and reduces actual use.
