Abstract

Objectives: Electronic cigarette (ECIG)-generated aerosol contains particulate matter with a diameter less than 2.5 microns (PM_2.5 ). Particles of this size may be injurious to the health of those who inhale them. Few studies have assessed the relationship between ECIG aerosol PM_2.5 and ECIG liquid ingredients or ECIG device power. Methods: Two studies were conducted in which participants generated aerosols with ECIGs. In one, ECIG liquids contained various vegetable glycerin/propylene glycol ratios; in the other, ECIG devices varied by electrical power output. Results: Results indicate that, in general, PM_2.5 increases as the ratio of vegetable glycerin to propylene glycol increases, or as device power increases. Conclusions: Regulating ECIG PM_2.5 emissions to protect non-users requires an understanding of all the factors that influence these emissions.
