(9,810 posts)We're working right now on figuring out how to standardize the data and get enough funding to do more samples. Basically, we did the experiment because our lab has several vapers and several... People who objected to them. (Science geeks' equivalent of a bar bet.)
Background nicotine in the local air is between 5 and 24 parts per million, with a statistical mean of 8.7 ppm.
The exhalation of a single puff by a regular user is between 6 and 28 ppm, with a statistical mean of 9.1 ppm.
Nicotine levels in a closed 8' cube where two vapers were going at their devices hard (every other breath for 5 minutes) were between 12 and 33 ppm, with a statistical mean of 14.5 ppm (which is still within the background levels). In comparison, the same room, with two burning cigarettes, was 390-570 ppm.
Statistically, it's a wash, given what we've looked at so far. (9 different users who all live at a mile above sea level, who each did ten exhalation captures.) it's a small data set.
