Respiratory symptoms among e-cigarette users without an established smoking history in the VERITAS cohort.

Prior research on e-cigarettes' health impacts is inconclusive due to confounding by previous tobacco smoking. Studies of e-cigarette use among people without an established smoking history are informative for this question. A cross-sectional survey was administered across six geopolitical world regions to adults aged 18+ without a history of established cigarette smoking or regular use of other nicotine/tobacco products.

Assessment and repeatability of aerobic capacity using the Chester Step Test among current, former, and never smokers.

Cigarette smoking contributes to reduced cardiorespiratory performance, which may improve upon cessation. Consequently, former smokers' cardiorespiratory fitness should not be significantly different from that of never-smokers. This study aims to compare V̇O values among current, former, and never smokers and assess the repeatability of measurements using the Chester Step Test (CST).
