[FONT=Default Sans Serif,Verdana,Arial,Helvetica,sans-serif]I've been in touch with:
Thomas Eissenberg, Ph.D.
Professor of Psychology
Institute for Drug and Alcohol Studies
Virginia Commonwealth University
Dr Eissenberg sent me a message today after his return from a conference in Ireland. As he is conducting research on blood nicotine levels with vaping I had asked him for some results. He doesn't have any himself yet but said Ruyan's team came up with this:
[/FONT][FONT=Default Sans Serif,Verdana,Arial,Helvetica,sans-serif]"... Bullen, Glover, Laugesen, Lin, McRobbie, and Thornley report that after 9 participants used the Ruyan device (16 mg cartridge) for 5 minutes, peak plasma nicotine concentration was 1.3 ng/ml (95% confidence interval = 0.0 to 2.6). In contrast, for those same participants, a cigarette produced a peak plasma nicotine concentration of 13.4 ng/ml (95% CI = 6.5-20)."
Then he went on to say:
"These data, if they are valid and can be replicated, provide little support to the manufacturers' claim that the devices can do what they are marketed to do: deliver a physiologically active nicotine dose to the lung.[/FONT]"
I am glad that we now have the first statistics on actual absorption of nicotine from vaping. This result is surprising to me though, it appears that 16mg nicotine eliquid gives a tenth of the nicotine to the bloodstream after five minutes vaping as a cigarette.
