Researchers are evaluating the effects of transcranial direct current stimulation tDCS on cannabis use disorder in people with schizophrenia. This study aims to see if 10 sessions of specific brain stimulation can reduce cannabis consumption, craving, addiction severity, and schizophrenia symptoms, while improving overall functioning. The study also explores possible changes in cognitive functions and brain connectivity related to these effects. Participants will receive either active tDCS or sham non-active stimulation using a Neurocan DC-Stimulator Plus device. Electrodes will be placed on the scalp to stimulate specific brain areas twice daily for 20 minutes each session over 5 consecutive weekdays. The control group will undergo a sham procedure that mimics the sensations of active stimulation without therapeutic effects. During the study, researchers will monitor cannabis use and craving scores at 3 and 6 months, hospitalizations, and brain connectivity changes through imaging studies. Participants will be assessed for schizophrenia symptoms and overall functioning. The study involves random assignment to treatment groups and double-blind masking to ensure unbiased results. Total involvement includes follow-up visits and evaluations over a 6-month period.
