Summary

This study looks at whether adding alcohol-related smells to virtual reality scenes makes people with alcohol use disorder feel stronger cravings. Sixty participants will experience different combinations of visual scenes (neutral or alcohol-related) and smells (none or alcohol). Researchers will measure self-reported cravings and heart rate changes to understand how multiple senses contribute to craving.
