Summary

This investigation will preliminarily determine if a course of high-frequency rTMS applied to the left dorsolateral prefrontal cortex, will reduce behavioral craving, and fMRI cue-reactivity in treatment-seeking cannabis use disordered participants.

Conditions

  • Cannabis Use Disorder

Interventions

DEVICE

Active rTMS

rTMS will be delivered via a MagPro double blinded rTMS Research System (MagVenture, Denmark) with a Cool-B65 Butterfly Coil (a combined active and sham coil). We will use a standard resting motor threshold (rMT) determination to determine the TMS dose. Study-treatment will be delivered at 120% rMT. Each active rTMS study-treatment will consist of a total of 4000 pulses of 10Hz stimulation (5s-on,10s-off). Study-treatments will be delivered at the EEG coordinate for F3 (which approximates the left DLPFC), and will be found using the Beam-F3 method.

DEVICE

Sham rTMS

Sham sessions will be delivered using an electronic sham system consisting of a coil that mimics the appearance and sound of rTMS, combined with a TENS device which produces a small electric shock mimicking the feeling of active rTMS. This type of sham has been demonstrated to be indistinguishable from active rTMS.
