About the trial

What the trial wants to find out

The purpose of this sham-controlled pilot randomized controlled trial (RCT) is to evaluate the feasibility, safety, and preliminary efficacy of a one-month intervention consisting of 20 home-based active or sham RS-tDCS sessions paired with audio track guided mindfulness meditation practice in otherwise healthy adults seeking to reduce cannabis use in the context of cannabis use disorder (CUD).

The 2 groups in the trial

  • Active tDCSTreatment being tested

    Participants will complete 20 remotely supervised (RS) daily sessions, each 20 minutes, of active dorsolateral prefrontal cortex (DLPFC) tDCS combined with mindfulness meditation.

    Treatment: Active Transcranial Direct Current Stimulation (tDCS) and Mindfulness meditation

  • Sham tDCSExisting treatment, for comparison

    Participants will complete 20 RS sham sessions, each 20 minutes, of active DLPFC tDCS combined with mindfulness meditation.

    Treatment: Sham Transcranial Direct Current Stimulation (tDCS) and Mindfulness meditation
