Yeah, yeah, yeah...
Everything you do including plain straightforward breathing carries a finite risk.
Life is a sexually transmitted condition that is invariably fatal.
Live with it.

It seems to be a little know fact, but one does not need to inhale the vapor of vaporizers to have the nicotine work. It's not the lungs that absorb the nicotine, it's the palate and olfactory area. The vapor particles are to big for the lungs to absorb it. So the inhalation is purely a preferred habit of most ex-smokers. The vapor would actually work better if one sloshed it around like vine, or vaped like a cigar.
Anyway, that fact would mute this whole article...

Study funded by... Big Tobacco? Shock, horror!

Life is the leading cause of death.

Any toxic substance injected into the body, by any means, is potentially harmful. Nicotine is a deadly poison, so it can do no good, however little you ingest, so why do it? If the suppliers were all charged with manslaughter, it would stop, but there is far too much profit, and tax to be gained for that!

Next, do salt inhalers. ...because I'm developing an addiction !

It only makes sense that inhaling any particulate matter or any type of smoke into your lungs is going to cause some kind of illness. You can say there is a risk to everything in life. But some serious risks like smoking/vaping are totally avoidable, so it's smart to avoid them and dumb to carry on as if there's no risk.

What you don’t mention are these important facts. The 44 septum samples were taken from 15 subjects, of which are smoking traditional cigarettes as well as vaping; and 12 were previous smokers. Therefore the sample base was tiny, and the damage could easily have been done by previous / present cigarette usage. The study almost certainly has some link back to big tobacco.

Rustgecko-- very well said. Public gullibility is NoT improving...

Decades of epidemiologic research bear out Rodu's findings. While no tobacco product is completely safe, smokeless products have been shown to be 98 percent safer than cigarettes. In the United Kingdom, the Royal College of Physicians reported in 2002 that smokeless tobacco is up to 1,000 times less hazardous than smoking, and in 2007, further urged world governments to seriously consider instituting tobacco harm reduction strategies as a means to save lives.
