Electronic cigarette vapor appears chemically incapable of causing cancer as cigarette smoke has done. E-cigarette vapor contains toxicants concentrations averaging less than one percent of the concentrations in tobacco cigarette smoke.
Governments looking to recoup future excise losses on declining tobacco sales could be tempted to tax e-cigarettes. This would make electronic cigarettes less price-competitive and would have the unwanted side effect of protecting tobacco sales.
These randomized controlled trials followed participants for six and 12 months, and found no serious adverse events attributable to electronic cigarettes.
Lung function was not signifcantly decreased in 15 smokers using e-cigarettes, or in 15 never-smokers inhaling the vapor of e-cigarettes or inhaling smoke; lung function was, however, significantly decreased seven percent by active tobacco smoking.
Arterial stiffness is not increased from vaping
Red and white blood cells are not increased in the peripheral blood in the first hour after an e-cigarette either actively or passively inhaled.
Nicotine administered by electronic cigarette can relieve chronic idiopathic neutrophilia.
Nicotine in e-cigarettes reduces the urge to smoke and improves mood, working memory, and prospective memory
QUESTION 1. DO E-CIGARETTES LEAD CHILDREN INTO SMOKING?
