Reduced Exposure Study Using THS 2.2 Menthol With 5 Days in a Confinement Setting Followed by 86 Days in an Ambulatory Setting

The main goal of the study is to evaluate if the ad libitum use of the THS 2.2 Menthol (mTHS) for 5 days in confinement, and after 86 days in an ambulatory setting, by apparently adult healthy smokers results in a reduction in the levels of biomarkers of exposure (BoExp) to selected harmful and potentially harmful constituents (HPHCs) compared to smokers continuing smoking their own preferred brand of menthol conventional cigarette (mCC) and smoking abstinence (SA). Smokers who remained abstinent from SA were used as a benchmark to provide context to the exposure reduction.
