Systemic absorption of nicotine following acute secondhand exposure to electronic cigarette aerosol in a realistic social setting.

Evidence suggests exposure of nicotine-containing e-cigarette aerosol to nonusers leads to systemic absorption of nicotine. However, no studies have examined acute secondhand exposures that occur in public settings. Here, we measured the serum, saliva and urine of nonusers pre- and post-exposure to nicotine via e-cigarette aerosol.

Cigar Use Symposium: Epidemiology, Toxicant Exposure, Health and Policy Implications.

Objective: Domestic cigar use has increased over the past 2 decades perhaps partially in response to cigarette restrictions and partially because cigars are used as vehicles for the delivery of marijuana. Although there is ample epidemiologic data to verify use and use patterns, there are relatively few studies that have looked at other aspects of current cigar use, advertising, toxicant exposure, and health effects.

Methods: Gaps in knowledge prompted a research symposium entitled .

Measuring PM2.5, Ultrafine Particles, Nicotine Air and Wipe Samples Following the Use of Electronic Cigarettes.

Background: Few studies have examined the extent of inhalation or dermal contact among bystanders following short-term, secondhand e-cigarette exposure.

Objective: Measure PM2.5 (particles < 2.

Nicotine Content and Physical Properties of Large Cigars and Cigarillos in the United States.

Introduction: Cigars are combusted tobacco products consisting of filler, binder, and wrapper, which are derived from tobacco. Despite the abundance of literature on the composition of traditional combusted cigarettes, research is limited on the physical and chemical properties of cigars. Therefore, research on cigar properties may be useful to better understand their health impact.
