    Me is thinking there is nothing definitive with the figures for ecig vapor.

    The margin error of 2.49 g/m3 from 3.32 g/m3m3. Miniscule at best, small to nothing at worst. They need to do better than that.

    What I am not understanding is why the margin of error for the tobacco smoke is 6.91???

    Anybody??
    Because I trust no-one Who tells me FACTS with no proof

    Characterization of chemicals released to the environment by electronic cigarettes use (ClearStream-AIR project): is passive vaping a reality?3

    Nicotine
    Among all, the most interesting aspects we observed was that nicotine was not detected in air during the e-smoking session, although liquids used for experiments contained it. On the other hand, 34 μg/m3 of nicotine were found during the smoking session. It should be made clear that, according to the information on packs, the amount of nicotine inhaled by smokers was about 11.4mg, while the amount of nicotine inhaled by vapers was about 17.6 mg. However the amount of nicotine reported on packs is the inhaled amount. This information does not give details about the real amount of nicotine inside the cigarettes and released in the air during combustion and from side stream smoke.
    Based on the observed results, we can conclude that cigarette smoking produces nicotine contam- ination in the air at least 35 times higher than e- smoking. This means that we need at least 35 vapers to produce nicotine level in air similar to the level produced by a single smoker.
    Moreover if we had balanced the tests, asking cigarette smokers to consume the amount of cigarettes necessary to match the amount of nicotine used by vapers, the latter should have smoked about 29 cigarettes, producing an expected nicotine concen- tration of about 52 μg/m3.
    It’s extremely difficult to discuss about the rea- sons for these results. We could suppose that there is a different absorption kinetics for nicotine. Or maybe the amount in play is extremely low, when compared to the nicotine amount released during traditional smoking. However beyond all these hy- potheses, which have not been verified, there is one fact: 5 vapers using e-cigarettes for 5h in a small room without renewal of indoor air do not produce detectable levels of nicotine in the air.

    Either google translate or the arabic language is very polite.

    I put in "I have no F***ing idea" and that's what I got.
    When you do it the other way though you get "I have no idea ridiculous"

    Either way I still have no idea.

    Why do I smell a rat and not Nicotine?? Maybe the funding spread?
