And even if vaping involved deeper inhalation than smoking, how would that demonstrate that vaping is more dangerous than smoking, especially since the vaper is inhaling far fewer carcinogenic chemicals - and at far lower levels - than the smoker?

What the study did show was subclinical evidence of impaired lung function, meaning that the observed (measurable) lung function was unchanged, but that there was evidence of physiologic effects consistent with some bronchial inflammation. What is not known is whether this acute bronchial inflammation has any significance in the long-term. The presence of bronchial inflammation may be a result of propylene glycol having a respiratory irritant effect. But this does not necessarily mean that long-term exposure would lead to any adverse effect on lung function. More research is necessary to clarify that point.

This story is particularly alarming, because it shows that for some anti-smoking groups, it really is no longer about health. It is solely about ideology. And apparently, the European Respiratory Society will cling to its precautionary ideology while smokers go to their graves.

The unfortunate part of the story is that California taxpayers funded this proposal to the tune of a quarter of a million dollars. What a waste of money. They could have saved the money because the researchers had already drawn their conclusions. Why waste the money on actually conducting research when the conclusions of that research have already been drawn, and disseminated!

Thus, before even conducting the study, these researchers have concluded that adult smokers and their family members are severely affected if they undergo surgery and return to a THS-polluted environment, because their healing process will be significantly delayed. Also, the researchers have concluded that individuals who are repeatedly exposed to thirdhand smoke have impaired healing. This includes elderly parents in households with smokers as well as housekeepers in hotels.
