Who can take part

  • Participants must be able to provide informed consent and function at an intellectual level sufficient to allow accurate completion of all assessment instruments
  • Participants must be between the ages of 18 and 60
  • Participants must meet DSM-5 criteria for at least moderate Cannabis Use Disorder, with use of at least 20 out of the last 28 days
  • Participants must express a desire to reduce cannabis use or quit
  • Participants must have a positive UDS for cannabis during their enrollment visit (confirming they are regular users)
  • The investigative team must believe each participant is a good study-candidate

Who cannot take part

About the trial

What the trial wants to find out

In this trial we will work with a group of participants who are having problems related to marijuana use (they have Cannabis Use Disorder) and who want to reduce the amount of marijuana they use or quit using marijuana completely. We are testing to see if a treatment called repetitive transcranial magnetic stimulation (rTMS) can help them achieve that goal when combined with a brief three-session counseling therapy. Participants will receive rTMS to one of two different parts of the brain (the dorsolateral prefrontal cortex--the DLPFC or the ventromedial prefrontal cortex--the vmPFC) to see if applying rTMS to one brain area is more helpful than the other brain area.

The 2 groups in the trial

  • Dorsolateral Prefrontal Cortex (DLPFC)Treatment being tested

    36 sessions of high frequency (10Hz) rTMS

    Treatment: Repetitive Transcranial Magnetic Stimulation (rTMS)

  • Ventromedial Prefrontal Cortex (vmPFC)Treatment being tested

    36 sessions of low frequency (1Hz) rTMS

    Treatment: Repetitive Transcranial Magnetic Stimulation (rTMS)
