interesting extract from the pdf
Dr. Laugesen’s tests also provided these conclusions, emphasizing the safety of electronic cigarettes over
tobacco products:
• “On a daily dose basis, TSNAs in the 16 mg nicotine e-cartridge are 1,200 times less than in the tobacco
of 20 manufactured cigarettes, and 3,000 times less than the daily dose in a can of Swedish moist snuff.
erefore, the Ruyan® e-cigarette cartridge does not contain carcinogenic levels of TSNAs, in that no
product containing these trace levels has been shown to cause cancer.”
• “e Ruyan E-cigarette cartridge liquid does not behave like a tobacco extract. e absence of a
monoamine oxidase (MAO) inhibitor effect means the e-cigarette has no detectable addictive potential
beyond that of nicotine.”
• “e e-cigarette shows no increase in expired CO. e absence of any such effect from the e-cigarette
shows that combustion does not occur—as confirmed by the lack of flame or smoke. As nicotine has a
low vapor pressure, the piezoelectric ceramic element in the e-cigarette is needed to cause vaporization
of the nicotine-propylene glycol solution. Cigarette smoke is produced by combustion at temperatures
of up to 1,000 degrees Centigrade, which is highly destructive, breaking up tobacco into free radicals
and many small harmful gas molecules such as carbon monoxide, butadiene, and benzene. us, mist
from the e-cigarette is created by vaporizing a liquid, whereas smoke is created by incinerating plant.”
•
rough an analysis of published data on nicotine absorption, informal comments of bystanders, and
the observation of e-cigarette smoking indoors, it was found that the e-cigarette generates no
sidestream smoke from its (artificially lit) tip, as opposed to cigarette smoke, which is a mixture of
sidestream smoke and exhaled mainstream smoke. In e-cigarettes, any exhaled PG mist visibly
dissipates to vapor within seconds. Non-smoking bystanders do not find the mist unpleasant. e mist
is odorless, and those close by quickly realize it does not have the odor of smoke or the irritating
quality of tobacco cigarette smoke.”
In contrast to the inhaled nicotine in cigarette smoke, the e-cigarette’s exhaled PG mist most likely contains
little to no nicotine and absolutely no carbon monoxide. It is therefore not harmful to bystanders because it
does not have a lit flame or produce combustion of tobacco smoke.
