The overarching goal of this proposal is to investigate if a course of excitatory DLPFC rTMS results in reduced cannabis cue-induced craving in treatment seeking individuals with CUD (Aim1). Additionally, the investigators seek to explore the mechanistic underpinnings of any observed effect, by collecting functional magnetic resonance imaging data during cannabis cue-administration before and after the treatment course (Aim 2). These aims will be addressed through a seven week, double-blind, randomized, sham-controlled study in which 72 treatment seeking cannabis use disordered participants (36/group) will be given 20 sessions of either Active or Sham excitatory rTMS applied to the DLPFC. TMS will be delivered in an accelerated fashion over two weeks (2 sessions each day, five days each week). TMS will be applied in conjunction with a validated two-session Motivational Enhancement Therapy (MET) behavioral intervention.
