E-Cigs Help Smokers Stop

[airboy]

I've read a lot of the medical literature on what contributes to smoking.

Cigarettes are both physically and psychologically addictive.  Physical addition is caused by the nicotine.  It is a very difficult addition for many (but not all) to break.

Still, there are far more ex-smokers in the USA than current smokers.  But it takes most people multiple attempts to quit.
