Interesting Invention - E-Cigarettes

The first patent for a "a smokeless non-tobacco cigarette" was made in 1963 by Herbert Gilbert.

(Gilbert described a device that replaced burning tobacco and paper with heated, moist, flavoured air, but his device involved no nicotine, it was more flavoured steam and didn't prove a commercial success. It wasn't until 2003 that the first nicotine based electronic cigarette was patented, by Mr Hon Lik, a Chinese pharmacologist. Manufactured to look like a traditional cigarette, the batter powered product contains liquid nicotine that is turned into a vapour which is then inhaled.

Just another way to part a fool from his / her money. I wonder if it could be turned into something useful like a drug delivery system.)
