Why would we want to suppress the provision of this information to the public? And what justification is there for a government-mandated suppression of the truth?

First, the advocates want e-cigarettes to be taxed, and it would be easier to tax these products if they are defined as tobacco products. It's hard to turn down a revenue stream when you see one, and "anti-smoking" advocates are apparently no different. They see a nicotine-containing product that some people are using for pleasure, and they immediately want to tax it, regardless of the fact that taxing e-cigarettes will increase cigarette use and kill people by removing the economic incentive for smokers to switch from real cigarettes to e-cigarettes.

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.

Yesterday, I explained that the of electronic cigarettes by Stan Glantz and colleagues published this week in the journal Circulation is because it draws conclusions about the efficacy of e-cigarettes for smoking cessation from studies that were not designed to measure such effects in the first place. These studies did not examine smoking cessation rates among a cohort of smokers who were identified at baseline as using e-cigarettes with the intention of quitting smoking. Moreover, smokers who use e-cigarettes are likely more heavily addicted to nicotine and may be more resistant to quitting, thus making inferences about cessation effectiveness from these studies inappropriate.

To be valid, the study needs to examine e-cigarette smokers who have not tried these products before and are trying them for the first time in an attempt to quit smoking. Otherwise, the study cannot truly claim to draw conclusions about how helpful e-cigarettes are for smoking cessation among cancer patients.
