Electronic cigarettes, also known as e-cigarettes, are designed as a substitute for cigarette smoking.
Some believe e-cigarettes help smokers quit. Operated by a battery, they work by turning nicotine into a vapor that is inhaled. Most e-cigarettes look like ordinary cigarettes, cigars, or pipes. Others are designed to look like pens or computer memory sticks. Their use has been increasing as new products have entered the market. The US Food and Drug Administration, which currently regulates nicotine products, has announced that it will expand its regulations to include e-cigarettes.
