I did the unthinkable for a vaper, and it was mainly my stupidity. I went back to cigs just to see how much different vaping really, really is, and wow. So I smoked the exact same way I vaped, and I noticed it took me 4 to 5 cigarettes to have the equivalent of 4 puffs off of my provari. So, vaping does deliver nicotine in a much safer way, and I feel it is more effective than cigarettes. Plus, I cannot get the awful taste out of my mouth. Does anyone else notice this? I tried smoking my old favorites, the Marlboro Reds, and I vape 18 mg 80PG/20VG?
