In Part 1, the purpose of this study is to elucidate the single-dose pharmacokinetic profiles of 1 spray and 2 consecutive sprays of oromucosal nicotine spray (ONS) in comparison with those of nicotine gum and cigarette smoking in healthy Japanese smokers. In Part 2, the purpose is to evaluate the multiple-dose nicotine pharmacokinetics of ONS administered repeated-dose administration in healthy Japanese smokers.
