Hi there, Ive ordered my first ecig and discussed it with family and friends and a few more want to try...Yesterday my mum was totally put off as my bro said ecigs cause mouth cancer(he has never tried them nor does he REALLY know anything about them)....I want to know where i can find the best info...not opinions but facts on ecigs to show him and others any possible negatives to ecigs and info to disprove the mouth cancer thing...what studies have been done?and what ones havent? Is there a "worst that can happen" article? and who exactly tests ecigs? are they pro or anti ecigs? I would say i will come across alot of people who make outrageous negative claims on these based on the "too good to be true if your a smoker" idea. I am totally converted to the ecig way of life and can see its potential for me and others but i dont want to advertise it to others without having the proper backup info.
