:::: Extra personal information: vapers use 100 percent of their lungs to inhale that chemical stuff reaching their small blood vessels in their lungs, people that smoke sigarettes and tobacco do not use 100 percent of their lungs so the smoke does not reach the smaller blood vessels in their lungs, thats why a scan shows vapers having popcorn lungs, small blood vessels all destroyed which is not the case with regular smokers, vaping is like the hookah you really need to use your lungs to inhale which is like I said not the case with regular smokers
