E-cigarettes are nonflammable. Since there is no flame or heat when you use these cigarettes, there is no risk of injuring yourself, others, or property. This means no burns on the couch, your clothes, the carpet, or in the car, and no harm to someone who accidentally bumps into you. It also means that you don't have to carry a lighter or a match book with you. Because there are no ashes, there is no need for ashtrays, and you will not have to look for a place to extinguish the butt and to dispose of it. When you are finished, simply put the cigarette in your pocket or purse.
