Thanks for the response guys. wave, don't feel bad lol, my dog likes the smell too, where before when I smoked cigs she would sneeze and run away lol. I've been reading up on the NZ study and here are some quotes I found in their research, pretty interesting.
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 6, and so the
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 Zealand’s Smoke-free Environments Act 1990.32
Inhalational safety in children. In a series of experiments to control airborne infections,
over 105 children were subjected to bactericidal concentrations of propylene glycol in the
wards of a children’s convalescent home in experiments conducted over 3 years.
Method. Six wards of the Children’s Seashore House in Atlanta containing 105 bedfast
children aged 3 to 15 years were divided into 3 control and 3 undergoing vaporization for
3 week periods with 2 to 3 days between, before the control wards become vaporized, and
the vaporized wards became controls. This rotation continued for 7 months. The PG was
heated to vaporize it, but not above 80 degrees C, and vaporization continuously
maintained a concentration of 0.069 mg per liter. (0.07 ppm)
Results. No ill effects were reported. In the first year, 100 infections occurred in control
wards without PG, and 5 in wards with PG vaporization, with rates of 0.18 per week and
0.09 per week respectively. Most of the upper respiratory infections in control wards
were common colds, suggesting the PG is also virucidal.
So, based on what this report found there was virtually no nicotine in the exhaled vapor, still to be on the safe side, I will make him steer clear of my clouds. I thought it was interesting though that they actually found the vaporized PG to be virucidial, having a healthier effect on children's immune systems.
