Cigarette Smokers

This is a parallel design cohort consumer use study to measure the puffing topography of two HTP devices, with two variants of HTP consumables ("sticks"), collectively referred to as the study investigational products (Study IP), among a sample of 240 primary users of combustible cigarettes in the United Kingdom (UK). Participants will be using the products for five days at home. Participants demographic characteristics (including age and biological sex), and tobacco- and nicotine-containing products (TNPs) use history will be collected using self-reported questionnaires. Participants will be asked to complete daily surveys using a survey link. Surveys will collect data on the number of CC smoked and number of sticks consumed the previous day in addition to any other tobacco or nicotine product used. In addition, at the end of the study, participants will complete a survey regarding overall product liking and purchase intent.
