Ok, I stumbled upon this patent assigned to Philip Morris Inc. quite a few years back. I haven't gone through much of it, but it seems something very, very similar to our electronic cigarettes. 


Ok, my question is, why would Philip Morris have a patent on this? You all know, if they were able to "sell" this it would in fact contain Nicotine (to keep people hooked). How would this be any different than the ecigs out today?
United States Patent: 5666977
There are pictures available if you click on Images at the top to see the actual patent documents.
Edit: After reading a little bit more, it seems as though they planned to use "actual" liquid tobacco, full of all their wonderful chemicals in the product and vaporize it with a heater to product it into an aerosol. How would our form of vaping liquid be more hazardous than that??
