Randomized Controlled Trial
Cigarettes with different nicotine levels affect sensory perception and levels of biomarkers of exposure in adult smokers.
Few clinical studies involving cigarettes have provided a comprehensive picture of smoke exposure, test article characterization, and insights into sensory properties combined. The purpose of these pilot studies was to determine whether cigarettes with different levels of nicotine but similar tar levels would affect sensory experience or smoking behavior so as to significantly alter levels of selected biomarkers of exposure (BOE). ⋯ These studies demonstrate that abrupt increases or decreases in nicotine and the resulting sensory changes impact BOE through changes in intensity or frequency of smoking.

Waterpipe (also known as hookah) smoking is increasing around the world, including the United States, where waterpipe bars have sprung up rapidly around college campuses. Users are exposed to several toxicants, including carbon monoxide (CO). We evaluated change in exhaled CO and estimated carboxyhemoglobin levels among waterpipe bar patrons in Tampa, FL. ⋯ U.S. waterpipe bar patrons are exposed to considerable amounts of CO, which could put them at risk of acute illness and chronic heart and lung diseases. Environmental and policy controls are needed to curb this increasingly popular tobacco use method in the United States.
