There might be some truth to the vaping and not getting sick as much thing....theres no doubt I get sick less since vaping. Perhaps it's not really vaping, but just the fact that I'm not smoking anymore. The sick part wasnt so bad, it was the 2 weeks after that which got me. After my cold went away, my chest congestion was aweful, couldnt breath and was constantly hacking flem...all that has completely gone
