Summary:

      Cannabis use disorders remain a significant public health problem. The pharmacological
      facilitation of behavioral treatment represents a promising strategy for addressing
      disordered cannabis use. Cannabis use disorders are recognized to be associated with various
      vulnerabilities that complicate the course of treatment and that may be amenable to glutamate
      modulators. The purpose of this single blind open-label trial is to test the feasibility of
      administering glutamate modulators in conjunction with motivational enhancement therapy (MET)
      and mindfulness based relapse prevention (MBRP) for cannabis use disorders.
