Here's a link to some good info.

I actually remember reading something about some stats that were gathered in China during the avian flu breakout over there. The one thing they found is that those that frequently used e-cigarettes seemed to be diagnosed with this new flu much LESS often as those that did not vape. I think someone concluded it was likely due to the PG concentration in the lungs (and possibly the air) and it's "powerful bactericide and virucide" attributes. I've looked for that article/post since but can't seem to find it, so take everything I just typed as hearsay.
Not doubting you on the effects of smoking one iota but hand sanitizer is part of their problem as well. There have been numerous studies that point to overuse of sanitizer products stripping away good bacteria and making people more susceptible to a host of illnesses. I'll stick to good old fashioned soap and hot water.![]()
I couldn't agree more!
I'm also of the opinion that it's important to give my immune system a little training every now and then. Which of course reminds me of a George Carlin rant!
