Nicotine Pharmacokinetics Following Use of the P4M3 Gen 2.0 E-Cigarette Compared to Smoking Cigarettes

This is a single-center, randomized, controlled, open-label, cross-over study with healthy adult smokers. The study will investigate the nicotine pharmacokinetic (PK) profiles of two e-liquid variants used with the P4M3 Gen 2.0 e-cigarette, compared to smoking combustible cigarettes. In addition, pharmacodynamic (PD) effects (subjective effects and related behavioral assessments), will be evaluated to provide further insights on product evaluation, craving, liking, puffing topography. The study will be conducted with three periods and six sequences in a cross-over design. This study is exploratory and there is no pre-specified hypothesis to be tested.
