E-cigarettes were invented in 2003 by Chinese pharmacist Hon Lik. They hit the US around 2006. Since then, countless variations on Lik's design have cropped up, but all essentially operate by using an electrical coil and wick system to vaporize a mixture of vegetable glycerin, propylene glycol, flavorings, and usually—but not always—nico2tine (aka “juice”) that come in any style from cotton candy to traditional tobacco.
