Advantage of electronic cigarettes is the fact that you are not really smoking anything. You do not have the kind of toxins and chemicals found in traditional cigarettes. In fact, cigarettes with tobacco burn about 490 different chemicals which you end up inhaling.
An electronic cigarette contains three essential components: A plastic cartridge that serves as a mouthpiece and a reservoir for liquid, an "atomizer" that vaporizes the liquid, and a rechargable battery (unless it's a disposable kind).
Electronic cigarettes have gained a lot of popularity since the early 2000s in hopes of replacing regular cigarette addiction for chronic smokers. Originally available in smoke shops and retail shops online, electronic cigarette is now a multi-billion dollar industry. With a massive market for e-cigs, companies now offer realistic flavors to promote their brands to the consumers.
Electronic cigarettes can be disposable kind or can be purchased as a kit. The advantages of disposable e-cig is simply the convenience of using it without having to worry about recharging the batter. Disposable e-cigs usually last about 500-700 puffs after first use. The advantage of buying a full kit allows you to save more money over time if you're a chronic e-cig smoker. Full kit usually includes an USB charger, wall charger, battery, nicotine cartridges, atomizer and a mouthpiece. Check the popular brands of electronic cigarettes to the right of the page.
