Savd me from a 1.5 pack a day habit since November 2, 2011. Cheaper, and I used flavored juice. Anyone else use these? Many upsides...less cost, no cig stink on clothes/hair/breath/car, can breathe better (I'm at 6mg nicotine, about half of an ultralight cig) no freezing my hands off at 6000 feet while snowboarding (or on my deck in February), feel better, get sick less often, can grab a discreet hit in theater/plane/long doc office wait without going outside or jit-fitting, no lighter needed, on and on... Downside...batteries going dead and having to explain that no, this is not a sneak-a-toke and no, you may not have a hit because no, this is not a sneak-a-toke!!!
