NCT05292547
UW21-656
  • Ages 18-65
  • All Genders

Study Summary

This study is to explore if repetitive transcrinal magnetic stimulation (rTMS) with different stimulation schedules will be equally effective in reducing carving, frequency of cannabis use, and the severity of cannabis use disorder in participants suffering from cannabis use disorder (CUD).

The investigators assume the hypotheses as:

  1. Multiple rTMS sessions can reduce craving for cannabis, severity of CUD, frequency and amount of cannabis use.

  2. Different rTMS treatment schedules have differences in reducing the craving for cannabis and severity of CUD, and prolonging relapse of cannabis use.
