I can&#x27;t really comment on your anecdotal experiment because well it wasn&#x27;t exactly done under controlled conditions and while i appreciate the level of accuracy you assign to your index finger i&#x27;m not quite sure how accurate it is really :)<p>And yes we already live in the world with 1000&#x27;s of environmental risk factors that may cause or increase the likelihood of contracting cancer, the first of which is probably the fact that if we survive trough our early 20&#x27;s we are expected to live another 60-70 years instead of 30 or so 2000 years ago.<p>But if you really think that regardless of flavor or composition vaping is some how smoking with no consequences you are only fooling yourself.<p>Vaping should be looked as a tool that can enable you to quit smoking more easily not as a leisure activity or a life style choice.<p>After all nicotine it self is indirectly linked to cancer since it seems to mess with the natural mechanisms that prevent cancer in cells.<p>As far as overall health goes I would suggest to stick to the low powered ecig pens and not dragging around one of those car battery powered human smoke machine monsters that I&#x27;ve seen quite a few folks walking about with lately (which are probably the reason that ecigs are being banned everywhere now, a vape-pen produces like no visible vapor; whilst those big power bricks can be used to conceal military maneuvers), as they operate at a fraction of the power and also limit the consumption of eliquid, them being also much more unpleasant to use than the higher end stuff should also have some effect on the frequency of use.
