Electronic cigarettes? replaceable cartridges with shots of nicotine but without the tar, tobacco or carbon monoxide.. users inhale a fine heated mist of nicotine..things are popular because they get around the ciggie ban in restaurants and public places, and you don't have to go outside to ' light up '.. couple that with the new ' energy drink' craze like Red Bull and its competitors; comes a nicotine ' energy drink'?? You get your nicotine fix by downing a can of fluid with the right ' mix'.. geeezuz!!! why not just slap a patch on and absorb the nicotine all day/every day with no need to ' taper off' or quit? people is krayzee!!!!
