No To E-cigarettes
Using E-cigarettes Is Substituting
One Bad Habit For Another
According to the National Institute on Drug Abuse e-cigarettes (a cigarette-shaped device containing a nicotine-based liquid that is vaporized and inhaled, used to simulate the experience of smoking tobacco) are not a safe substitute for smoking a conventional cigarette. Like cigarettes, they also contain nicotine and other potentially harmful chemicals.
Studies are still being done, but as long as you are getting nicotine, your health is under threat. Instead of helping someone stop smoking, e-cigarettes may merely prolong the time someone smokes.
