This study, although limited to only three brands of electronic cigarettes, provides reassuring evidence that there do not, at present, appear to be major concerns about substantial health hazards associated with secondhand exposure to electronic cigarettes.

While the FDA has given its official stamp of approval to the "normal" cigarettes that are killing more than 400,000 Americans each year and has taken no action to reduce the hazards of smoking, we can all be grateful that the agency has stepped in to protect the public from cigarettes that smell or taste wrong.

In contrast to what ANR is stating, the study found no effect of e-cigarettes on lung function, as measured by spirometry. This is in contrast to tobacco smoking, which does have effects on lung function that can be measured using spirometric testing. While previous research indicates that active smoking and even secondhand smoke exposure can affect acute lung function as measured by spirometry, the study demonstrated that electronic cigarette use led to no impairment of lung function detectable via spirometric testing.
