Secondhand smoking is linked to side-stream smoke which simply doesn't exist with vaping and with high levels of toxicity in smoke which doesn't exist either in the vapor exhaled by vapers. Tobacco smoke is lingering in the air for minutes as vapor condense in seconds. Multiple studies on vaping have showed levels that are not even clinically significant in chemicals that could, at far higher doses, present any risks.

Those people searching years after years for reasons to limit vaping, not even doing a good scientific job (comparing vaping to smoking is flawed as it they have nearly no reason to have anything in common), are simply lost souls in an endless battle against tobacco now completely losing their way fighting the one thing that has replaced smoking with a safer alternative for millions of people all over the world.

Please stop using science in a hysterical moral or economic battle and begin to really study. Stop using the same tactics you reproach tobacco company of using. There certainly are improvements to do on eLiquids and vaping devices to make them even safer, even more attractive than they are to lure more and more smokers away from tobacco and make tobacco-related diseases a thing of the past.
