It's less a cigarette and more an electronic nicotine delivery system, seemingly an updated version of this thing. It doesn't produce any smoke, but does hit you with nicotine. It costs $100, and five replacement cartridges run $10. Each cartridge is allegedly the equivalent of two packs of cigarettes, so if you've ever wanted to OD on nicotine, I'd say this thing is your best bet. Neat idea, but I'll just stick to my Sherlock Holmes pipe. Because nothing says "I'm all class" like puffing on a pipe and ogling the ladies through a monocle.
