Study finds acute active and passive e-cigarette vapor exposure does not influence complete blood count (CBC) indices in smokers and never smokers, respectively. In contrast, acute active and passive tobacco cigarette smoking increase the secondary proteins of acute inflammatory loadwhite blood cell, lymphocyte and granulocyte counts for at least one hour.

[h=2]Abstract[/h]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 conditionsession, an active tobacco cigarette smoking conditionsession, and an active e-cigarette smoking conditionsession. Never-smokers underwent a control conditionsession, a passive tobacco cigarette smoking conditionsession, and a passive e-cigarette smoking conditionsession. The results demonstrated that CBC indices remained unchanged during the control conditionsession and the active and passive e-cigarette smoking conditionsessions (P>0.05). Active and passive tobacco cigarette smoking increased white blood cell, lymphocyte, and granulocyte counts for at least one hour in smokers and never smokers (P<0.05). It is concluded that, for acute active and passive smoking using the e-cigarettes tested in the current study, acute active and passive smoking does not influence CBC indices in smokers and never smokers, respectively. In contrast, acute active and passive tobacco cigarette smoking increase the secondary proteins of acute inflammatory loadwhite blood cell, lymphocyte and granulocyte counts for at least one hour. More research is needed to evaluate chemical safety issues and other areas of consumer product safety of e-cigarettes, because the nicotine content in the liquids used may vary considerably.
