First seen Jan 04, 2026 · Last updated Jun 21, 2026 · Updated 27 times

Summary

This small, early-phase study tested whether a single dose of sedatives like ketamine, midazolam, or dexmedetomidine could reduce cigarette cravings and smoking in 20 daily smokers. Participants received one of these drugs or a placebo (saline) and reported their cravings, withdrawal symptoms, and how many cigarettes they smoked. The goal was to understand how these drugs affect smoking behavior, not to find a treatment yet.
