Is nicoten vapour dangerous? it says extremely toxic if in contact with skin. so what is it doing to our insides? i am reffering to ecigerrets.

Electronic cigarette: There are ecigarettes whose liquid does not contain nicotine. There are still studies going on and the best unbiased overview is at http://en.Wikipedia.Org/wiki/electronic_cigarette.

We Don't Know: You asked a great question. E-cigs are relatively new and their long ; short term effects have not been studied to the point of fully knowing what they may do to us. I do believe that that may prove to be a useful tool for someone trying to stop tobacco use all together if used very short term because other additives in tobacco cause some cancers ; problems. Still i would not use them.

Nicotine is bad: The smoke from smoking any tobacco product contains many dangerous elements that may cause cancer, chronic obstructive lung disease, bad breath, teeth staining, dries the skin on your face etc. Why take chances? Stop smoking.
