The public conversation around electronic cigarettes (e-cigarettes) is heating up, as these tobacco substitutes, thought by many to be the miracle cure for smoking cessation, are the subject of studies, legislation, and policy-making. Proponents of electronic cigarettes are adamant that they provide a safe alternative to traditional tobacco products, while opponents indicate concern that they could pose other health risks, particularly to children, who might view them as an acceptable and legal way to participate in cigarette culture.

Specifically, electronic cigarettes are made in the same shape as regular cigarettes. They are battery powered to heat liquid held internally, which produces a flavored nicotine mist when users inhale, similar to a nebulizer or a humidifier. The liquid is based in propylene glycol or glycerin, and it has no offensive odor. Users experience the same physical feelings as equivalent amounts of nicotine are delivered, making them a popular alternative to such products as nicotine patches, lozenges, and gum.

Although they need an initial outlay that can be quite pricey, the majority of vapor cigarettes are reusable, with parts that can be replaced and refilled. The liquid is held in a cartridge, which is also the component placed in the mouth. This is attached to an atomizer that contains the heating element. In order to keep liquid from moving through the cartridge into the user?s mouth, the internal design includes an absorbent sponge inside the cartridge. On the other end, a filament and wicking metal mesh draw the liquid towards the atomizer for vaporization. It is this filament that often stops working first on reusable models, and must be replaced, as material builds up or the component burns out altogether.

Disposable cartomizers are also available that integrate the cartridge and the atomizer, and they are typically sold at a lower price, but must be purchased more often.
All electronic cigarettes have a power supply, often in the form of a battery for those designed to be portable. Typical products use a lithium-ion battery that can be recharged through a USB connection. Chargers are sold in an array comparable to cell phone charger options, with selections for AC outlets, cars, or USB-ready devices. Many electronic cigarette companies offer portable charging cases that are intended to resemble cigarette packaging. They contain large batteries that, when activated, charge the smaller individual batteries.

Depending on the form, e cigarettes might have a power switch that must be turned on before the heating element will start. Alternatively, some are automatic and are triggered when the user inhales through an e airflow sensor. Many styles prevent overheating with a programmed cutoff after a certain amount of time.

The liquid needed for vapor production is sold both in bottle form for manual refilling, as well as pre-filled cartridges meant for single use. Referred to by manufacturers as nicotine solution, e-liquid, and e-juice, the concoction contains the base, water, and flavorings, as well as varying amounts of nicotine, labeled for purchase according to user preference. A wide variety of flavors are produced to appeal to every palate, from those intended to imitate traditional cigarettes, both regular and menthol, to an assortment of fruits and sweets, such as strawberry, chocolate, and vanilla.

As electronic cigarettes gain popularity, the technology is expected to advance. Longer battery life and lower cost are at the top of user requests.

Smokeless cigarettes is a much safer alternative to deadly tobacco. Know all that you need on vapor cigarette.
