Don't minimize the effect of nicotine on the body. It is not benign. It is addictive. It won't cause cancer but it does cause harm. It is a pesticide - a poison. It changes the brain much in the way that heroin does. It causes liver dysfunction, affects the cardiovascular system, affects the kidneys, and much much more. The ecig- containing less chemicals than tobacco - still contains at least 3-4 carcinogens. The chemical that causes the vapor to form is harmful to the human lung. We have had a few patients with lung disease admitted to the hospital from using the ecig. Studies have not been conducted to prove the safety of the ecig, it is not proven nor does it have a track record for smoking cessation, and there are no industry standards or safety measures. You don't know where those liquids are made or what is in them.
