There are NO "health benefits" to using electronic cigarettes!!!!
E-cigs are simply vaporized nicotine. People believe that they've "quit" smoking, and the only fact is that they aren't inhaling combustible plant matter and chemicals. So, they aren't "smoking," per se, but they are feeding their oral fixation by putting the tube in their mouth and inhaling vaporized nicotine.
E-cigs are NOT the solution to tobacco addiction.
