As many of us who have been e-Smoking and doing research on the subject, are aware of the studies of Propylene Glycol that was done in the 40s. There have many discussions on this subject, and some have surmised from this study that PG can keep you from getting sick.
Since I started vaping, I have gotten sick, but only once.
I tend to chain vape, mostly with no-nicotine or low nic, yet I got sick. But I can tell you that I continued to e-Smoke all during my illness, and either I had a very weak cold, or perhaps the PG kept the virus in check. I am not a doctor so I cannot say one way or the other.
I was just reading this article about all the fake flu cures and remedies that are floating around on the Internet, One of which is to use an e-Cig, citing the 1940s study.
I thought it be pertinent to recommend not to rely on any of these false or unproven claims.
As I have read, the best recommendations to avoid getting sick is mostly common sense. Wash you hands often and avoid touching your face, eyes, mouth and nose.
Of course you can vape'em if you got'em. But only for your enjoyment, and not for a cure.
Here is a link to the article I mentioned.
