Electronic cigarettes are OK. But when you need to tell the world that your tobacco habit is tops, you need an electronic cigar.
By NJoy, the NROBO is a disposable cigar that's good for 1,500 puffs. It's automatically activated when you take a puff, vaporising an internal nicotine/water solution. The air resistance is just right, though the flavour is somewhere around 1/1000th of a normal cigar. (Then again, the odourless smoke is something that most people around you will appreciate.) You can pick up an NROBO soon for about $US40 if you're interested in fellating a robot without all the cleanup.
