The aim of this study was to assess the effectiveness of a new nicotine lozenge ( Nicopass 1.5 mg) in reducing smoking urge after an overnight abstinence. Twenty-four moderate smokers participated in a randomized, double-blind, placebo-controlled, 2-period crossover trial. The results showed that 1.5 mg-nicotine lozenge is superior to placebo in reducing smoking urge (p = 0.0001). In addition, nicotine lozenge, but not placebo, significantly improved vigilance and psychomotor performances (p < 0.05) and displayed a cardiac chronotropic effect. Thus, the 1.5-mg nicotine lozenge appears as an effective aid to alleviate acute tobacco withdrawal symptoms in moderate smokers.
