*Smokers using [[Special:MyLanguage/Abbreviations|EC]]s over 4 weeks maintained cotinine levels and experienced significant reductions in carbon monoxide, [[Special:MyLanguage/Abbreviations|NNAL]], and two out of eight measured [[Special:MyLanguage/Abbreviations|VOC]] metabolites. Those who switched exclusively to ECs for at least half of the study period significantly reduced two additional VOCs.
