go to alt-smoke downtown in columbus, they have the bad-ass legit e-cigs with powerful batteries, and adjustable voltages i think is the right way to say it. anyway, i have friends who quit cold turkey for these and haven't smoked in at least 6 months. and these are people who were 2 packs a day smokers... I'm going down soon to get my kit to get set up. you can get started with a middle of the road product for 50-100 bucks. and they are really good, not the cheap low dosage stuff, you can really get buzzed if you arent careful on these, you can also adjust the nicotine concentration as you go. try it out!!! alt-smoke in columbus is the place to go
