Electronic cigarettes require more suction than conventional brands
Date:7/28/2010

s are used, requiring stronger puffs over time to sustain density," Talbot said. "Manufacturers often claim that e-cigarettes cartridges are equivalent to a certain number of conventional cigarettes. However, this information seems misleading."

Talbot's lab found that while the first ten puffs of an e-cigarette are similar to a conventional cigarette, later puffs were highly variable in aerosol density and do not duplicate smoking of conventional brands. The researchers found that even though one e-cigarette cartridge may smoke for 200 puffs, cartridges do not smoke uniformly for those 200 puffs and therefore do not duplicate nicotine delivery of individual conventional cigarettes.

"Our results show that e-cigarettes smoke very differently than conventional brands," Talbot said. "In preliminary trials, we observed that some brands of e-cigarettes were difficult to smoke possibly because they have relatively small air intake holes. Moreover, the interior of e-cigarettes is dense compared to the relatively porous tobacco-containing cigarettes."

Talbot, who is also the director of the UCR Stem Cell Center, was joined in the research by Anna Trtchounian, the first author of the paper, and Monique Williams of UC Riverside.

The study was supported by the University of California Tobacco-Related Disease Research Program; the University of California Academic Senate; and the Hispanic Serving Institutions-California Cost Reduction and Access Act Science, Technology, Engineering, and Mathematics Pathway Project.

"This paper is the first detailed study showing that greater inhalation pressure is required to smoke e-cigarettes as compared to conventional cigarettes," said Kamlesh Asotra, a research administrator at the University of California Tobacco-Related Disease Research Program. "An important implication is that users must exert greater inhalation pressure and, therefore, it may pred
