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.

3. The regulations require pre-approval or substantial equivalence determinations of almost all existing electronic cigarette products.
