So I'm going to open with e-cigs are the best thing to happen to me. Purchased a 510 December and tossed out my smoking-everywhere POS. Had the 510 till 4 days ago when i got my XHaler. With both the 510 and the Smoking-everywhere I would occasionally crave a real cig. After purchasing my XHaler i have smoked in bars at work and with my friends and not wanted to touch 1 cig, as a matter of fact the smell is beginning to disgust me.
