This trial tests whether a treatment called repetitive transcranial magnetic stimulation (a non-surgical magnetic stimulation to the brain) can help people reduce or stop cannabis use. You may be eligible if you have cannabis use disorder and meet specific safety and symptom criteria.
This early-phase study uses brain scans to study cannabis use disorder and looks at whether a treatment approach is suitable for people who use cannabis every day. It may help researchers understand brain changes related to quitting and recovery.
This study uses brain imaging to understand how thinking works in people who use cannabis, comparing those with psychosis to people without psychosis. It may help researchers learn what brain patterns relate to thinking difficulties and how cannabis use fits in.
This study looks at what happens in the brain when teens with cannabis use disorder stop using cannabis for 6 weeks. It uses MRI scans to see changes in areas that control habits and decisions.
