Summary

This study tests whether suvorexant, a drug approved for insomnia, can reduce cravings and brain responses linked to smoking in daily smokers. Researchers will also study how it affects thinking and reward processing in non-smokers. The goal is to understand if blocking a brain chemical called orexin can help prevent relapse in nicotine addiction.
