Light therapy may ease cocaine withdrawal and cut relapse

This study tests whether bright light therapy can help people going through cocaine withdrawal in a hospital. Cocaine withdrawal often disrupts sleep, mood, and daily rhythms, making it hard to stay drug-free. The therapy uses a special lamp to mimic daylight, which may improve sleep, mood, and reduce the urge to use cocaine again. Researchers will track 256 adults over one month to see if light therapy leads to more cocaine-free days and fewer relapses.
