Scientific American hasn't always been that 'kind' to ecigarettes. Early articles featuring Stan Glantz were not that good:
Financial Times and Scientific American weigh in - vaping.com
"Speaking of anti-vaping enthusiasts, the SA article now brings in the one expert quoted in the article, and it is Stanton Glantz, “a self-described e-cigarette pessimist” whose data and interpretations of data are widely viewed, even by his supporters, as exaggerated anti-vaping campaigns.
The SA article concludes with a question about whether “e-cigs are genuinely safe”, meaning: are they safer than swimming in the ocean, flying in a plane, or using a food processor. If they're not safer than all those everyday things and more, then smokers should just keep on smoking and dying, according to the
Scientific American."
