E-cigarettes, also known as electronic cigarettes and vaporizer cigarettes are devices that emit doses of vaporized nicotine that are inhaled. The device is battery-operated and can also emit non-nicotine vaporized solutions. Manufacturers say they are an alternative for tobacco smokers who want to avoid inhaling smoke. Tobacco smoke contains over 4, 000 different chemicals, many of which are hazardous for human health.Manufacturers and a significant number of users say the e-cigarette provides a similar sensation to inhaling tobacco smoke, however, there is no combustion (no smoke).

E-cigarettes are long-shaped tubes, many look like the product the user used to smoke, such as a cigarette, cigar or pipe. Some look like ballpoint pens (biros). The majority are reusable with replaceable and refillable cartridges. A small percentage of products are throw-away ones - disposable e-cigarettes.
