My sister got my dad an e-cig for xmas. The deal is she hates smoke, and had a baby on the way (born Feb 27th, Aaron "Danger" Susler!), so the ultimatum was if you smoke, you won't get to see the kid. So far he's still smoking... Also, he's been off work for 5 months & whines about not having any solid income. Fucking hypocrite.
Anyways, the thing works if you are willing to try it, and can save tons of money if you want to keep using it. The "smoke" is just a water mist, and you get it w/o really trying. Just don't try too much too soon. My dad smokes fairly heavy, and got a bad buzz after 3 puffs.
Healthy or not, you at least won't be dumping all that tar into your lungs, or anyone else's.I must be cut from a different mold. I've smoked crack before, and had no inkling to have it again. Same with weed (unless someone just happened to give me some).
