This study is testing a treatment called transcranial direct current stimulation (tDCS), which uses small electrical currents applied to the scalp to stimulate brain activity. Researchers want to see if this technique can help people who have both schizophrenia and cannabis use disorder reduce or stop their cannabis consumption. About 110 people will participate, and half will receive real stimulation while the other half receive a placebo stimulation that feels the same.
People with schizophrenia often struggle with cannabis use, which can make their condition worse. Current treatments don't always work well for this combination of problems, so researchers are exploring whether this brain stimulation technique might offer a new way to help.

You will attend stimulation sessions twice a day for 5 weekdays, with sessions lasting 20 minutes each. During each session, small sponge electrodes will be placed on your scalp and deliver mild electrical current. You'll receive either active brain stimulation or a placebo stimulation that feels similar; neither you nor the researchers will know which you're getting until the study ends. The study team will monitor your cannabis use and symptoms throughout the trial.
