Zealand research presented in Dublin at the 15th Annual
Conference, Society for Research on Nicotine and Tobacco, (SRNT) conference,
Safety: Ruyan e-cigarette benchtop tests. Poster 5-11.
The poster itself is found in the
following two powerpoint files: http://www.healthnz.co.nz/DublinEcigPoster1.ppt
The mist of the e-cigarette has been
rigorously tested. Of over 50 priority-listed cigarette smoke toxicants
tested, none was detectable in the mist of the RuyanŽ e-cigarette, except
for a trace of mercury close to the limit of detection. Some toxicants
remain to be tested before the results are submitted for publication. On the basis of findings to date,
inhaling mist from the e-cigarette is rated several orders of magnitude
(100 to 1000 times) less dangerous than smoking tobacco cigarettes. The
nicotine dose per puff is comparable to that of a medicinal nicotine
inhaler. E-cigarette nicotine is apparently not absorbed from the lung, but
from the upper airways.
Comment: Given that continued smoking of cigarettes carries a cumulative 1
in 2 death risk, the findings, argue for
1) less stringent regulation for very
low-risk non-medicinal nicotine cigarette substitute products
2) the sale of
this brand as a non-medicinal
cigarette substitute, as its emissions have been tested.
Status: June 2009: to be submitted for publication in a peer-reviewed
final tests completed, submitted to journal.
