I have been using ecigs since 4/1/2013. No more analogs for me. I really enjoy my ecig. However, the thought recently occurred to me...........if smokeless tobacco causes mouth, throat, and other cancers, then wouldn't ecigs, too? I have been doing tons of research but can't find any hard facts. All I know is that people that chew tobacco don't cough or wheeze like cigarette smokers, but they end up getting cancer nonetheless. I no longer cough or wheeze now that I vape, but in the end will I end up getting cancer from this Ecig?
