we know that most vapors were 1 to 2 PAD smokers, and now use 2 to 3ml of 24mg liquid, or 3 to 4ml of 18mg liquid (with a tendency to use either more or less depending on increased or decreased strength). We know that there is no combustion involved, so how much nicotine is actually delivered?
We know it is more than none[iv] and less than 100%[v] since nicotine is detectable in the exhaled vapour. The levels of nicotine in exhaled vapour are low. In fact, nicotine was detected in vapor exhaled directly into a 10 litre test vessel but was not detected in an 8m3 room test. Indeed, the Clearstream study[vi] confirms that nicotine levels found in indoor air after vaping are extremely low:
“Nicotine concentration in the air from the traditional cigarettes was on average 0.034mg/m3, while for the electronic cigarette it was less than 0.001mg/m3”.
keep on the vapor its not as much as a concern as one may think
