Acute impact of active and passive electronic cigarette smoking on serum cotinine and lung function.

Context: Electronic cigarettes (e-cigarettes) are becoming increasingly popular yet their effects on health remain unknown.

Objective: To conduct the first comprehensive and standardized assessment of the acute impact of active and passive e-cigarette smoking on serum cotinine and lung function, as compared to active and passive tobacco cigarette smoking.

Materials And Methods: Fifteen smokers (≥15 cigarettes/day; seven females; eight males) and 15 never-smokers (seven females; eight males) completed this repeated-measures controlled study.

Acute effects of electronic and tobacco cigarette smoking on complete blood count.

The World Health Organisation called for research assessing the safety of electronic cigarette (e-cigarette). We evaluated the acute effect of active and passive e-cigarette and tobacco cigarette smoking on complete blood count (CBC) markers in 15 smokers and 15 never-smokers, respectively. Smokers underwent a control session, an active tobacco cigarette smoking session, and an active e-cigarette smoking session.
