Hey all. I have to give an informative speech in a few weeks and I chose electronic cigarettes as my topic. Since it's informative only, I was thinking about just discussing it's history, how it works, and possible benefits/dangers. Do any of you know any interesting articles about ecigarettes I can use as sources for my speech? I am in the process of scouring google and ECF for sources but I tought that it may be also good to ask all the experts here.
