I've been trying to avoid the Dr's health report simply because its was too long and I am too lazy...
I'm glad you pointed me to this direction again, and finally I've run through it (if not READING!)
Anyway, I've extracted the following which relates to this topic..
"Repeated exposure to inhalations of theatrical smoke, including PG, was studied by
10,11 Varughese and colleagues in 101 employees at 19 sites. They did not report propylene glycol effects separately. They found wheezing and chest tightness correlated with higher cumulative exposure to smoke over the previous 2 years. Glycol fogs in particular were associated with acute cough and dry throat. Those with greater proximity to fog source showed significantly decreased lung function."
"The mist contained propylene glycol, ethyl alcohol; nicotine and acetaldehyde were minor peaks. "
"propylene glycol vapor is bactericidal, and virucidal against airborne
aerosol particles, and is associated with reduced respiratory infections in 30 children
continually exposed to propylene glycol vapor"
And finally, the MOST important
"5. Safety of Ruyan® e-cigarette smoke for bystanders.
Method. Analysis of published data on nicotine absorption, and informal comments of
bystanders, and observation of e-cigarette smoking indoors.
Results. Cigarette smoke is a mixture of sidestream smoke and exhaled mainstream
smoke. In constrast, the e-cigarette generates no sidestream smoke from its (artificially
lit) tip. Any exhaled PG mist visibly dissipates to vapor within seconds. Non-smoking bystanders do not find the mist unpleasant. The 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.
Comments. Inhaled nicotine in cigarette smoke is over 98% absorbed
exhaled mist of the e-cigarette is composed of propylene glycol, and probably contains almost no nicotine; and no CO. (see Figure 3.5) Lacking any active ingredient or any
gaseous products of combustion, the PG mist or smoke is not harmful to bystanders. The smoke or mist is not tobacco smoke, and not from combustion no flame is lit and is not defined as environmental tobacco smoke. E-cigarette smoking would be permitted under New Zealands Smoke-free Environments Act 1990.
YIPPPEEEE!!!!!
