 Please do not compare 'e-cigs' to vaporizing a tobacco plant; because vaporizing is nowhere near as 'safe' as e-cigs. Tobacco is tobacco, end of story. The only thing dangerous about 'e-cigs' is some moron vaping too high of a concentration of nicotine. 
There are absolutely no harmful chemicals in liquid nicotine (provided you get it from a reputable source and not some joe making it in his back yard). 
With e-cigs, the ONLY things you are taking in to your body are:
nicotine - which is technically a poison if used at too high a concentration and is a diuretic but won't kill you if you're not a moron. There are zero cancer causing chemicals in liquid nicotine.
propylene glycol - which is used to cut higher concentrations of liquid nicotine, and provides the 'throat hit' as well as a small amount of water vapor; and is found in millions of products from food to beauty products, and everything in between.. and is harmless.
Vegetable glycerin - which is used to cut higher concentrations of liquid nicotine and generally mixed with propylene glycol in order to reduce 'throat hit' and produce more water vapor.
A few other ingredients that are found in various flavorings - there are guidelines that explain which flavoring liquids are safe, generally anything that doesn't contain artificial flavoring and food coloring/dye. These flavorings are harmless as well.
I posted a list above of chemicals found in natural tobacco, before it's burned and smoked. There are a lot more that come from the smoke, but the list above is what's found in the plant itself. Not to mention other chemicals used in the growing/harvesting process.
