Another point I should make about the electronic cigarette (I'm not trying to 'advertise,' but I'm just saying I love my v2. I really do) is that you have to look at it almost as if you're smoking hookah, not a cigarette. You can get tobacco flavored cartridges, but it's basically a tobacco flavored sheesha(or 'hookah tobacco'). I smoked Marlboro Reds when I smoked, but now I usually smoke the menthol cartridge.
I'd like to add, that after a month of not smoking, which happened pretty much instantly after getting the ecig, I smoked a cigarette. My boyfriend and I bought a pack for our birthdays, which are close together. I thought it would be a terrible idea, but because of how awful it tasted, it only cemented for me how much I love my electronic cigarette. I don't feel like I'm about to double over and die after smoking my ecig for a while. But getting halfway through a real cigarette? Oh my god, it was awful. But then again, I REALLY needed to quit smoking. I was to the point where I couldn't only just not breathe when I woke up, but throughout the day every day I was hacking stuff up and gasping for air. It was really terrible, and now I can breathe again. :) It's nice being able to feel cold air go into your lungs, and not feel like death is right around the corner.
