What this trial studies

This is a sham-controlled, pilot randomized trial testing a one-month program of 20 home-based repeated-session transcranial direct current stimulation (RS-tDCS) paired with audio-guided mindfulness meditation. Eligible adults (ages 22–65) who meet DSM-5 criteria for cannabis use disorder and want to reduce use will be randomized to active or sham stimulation while completing guided mindfulness tracks. The trial focuses on feasibility, safety, and preliminary signals of reduced use or craving, with urine testing and clinical measures used for outcomes. Procedures include on-site screening and device training at NYU Langone followed by remote supervised sessions at home.

Who should consider this trial

Good fit: Adults 22–65 who meet DSM‑5 criteria for cannabis use disorder, test positive for cannabis, want to reduce or stop use, have minimal-to-moderate psychological distress, can use a mobile device, and speak English or Spanish.

Not a fit: People who use cannabis only as prescribed, have recent other substance use disorders or significant psychiatric disorders, or cannot operate mobile devices or attend required on-site visits are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, this could offer an accessible, non-drug at-home option to help reduce cravings and cannabis use.

How similar studies have performed: Prior tDCS research for substance use disorders has shown mixed early results, and combining remote tDCS with guided mindfulness is a relatively new approach that remains largely unproven.
