When I am smoking electronic cigarettes, I am getting all of the nicotine that my body demands. Smoking electronic cigarettes does not involve any tobacco burning and there is no tar being inhaled into lungs.
I started using e-cigs last week and I have not enjoyed a real cigarette since. The day after I began my e-cigs, I decided to try a regular cig just for the heck of it. It was SO GROSS! I now consider myself to be a quitter!
I am using SmokeTip (best company EVER) and I recommend them to everyone I know who smokes!
