A young woman strolls toward you at the mall, puffing on a cigarette. In most states, it's been years since such a thing was allowed and you do a double take. But something seems a little… off. When she exhales, you see something that looks like smoke, but it doesn't smell. And the lit tip of the cigarette emits a blue glow. Turns out that she's demonstrating an e-cigarette—an electronic device that vaporizes nicotine and has been touted by manufacturers as a safer alternative to cigarettes and other tobacco products.

E-cigarettes, also called e-cigs or personal vaporizers, were developed in China in 2003 and have been available to consumers since 2004. They're designed to mimic the size and appearance of a traditional cigarette, although cigar- and pipe-shaped models are also available. In an e-cig, a heating element atomizes liquid nicotine in a cartridge, delivering a smokeless, scent-free dose of the drug without many of the carcinogens found in tobacco products. E-liquids are available in different concentrations, just as cigarettes are available in light and ultralight formulas.

Automatic e-cigs work when the user inhales; manual versions require the push of a button on the "filter" portion of the device. Most models operate using lithium-ion batteries, and many users opt for rechargeable models that power up via wall outlets, USB ports, or a car's 12v charger. The LED light at the tip of the e-cig usually comes with different color options and signals that the unit is activated, as well as adding to the realism of the experience.

The e-cigarette emits a thick vapor that is closely similar to that of actual cigarette smoke. However, unlike the case of tobacco smoke, tar is absent, together with a fraction of more than 4000 chemicals that are contained in a standard tobacco cigarette. The e-cigarette vapor is created using a heating element, or an atomizer. This heating element heats a small liquid amount in a way that is similar to a fog machine, hence creating a vapor with the same consistence and flavor as tobacco smoke. An electronic cigarette does not emit any actual smoke, meaning that there is no need for ignition from a lighter or match. Hence, there is no fire hazards risk or second-hand smoke.Do you know the development of ecigs in other countries,like the US?

E-Cigarette Battery

The e-cigarette battery is automatically turned on during inhalation, and when the smoker completes the drag it automatically shuts off, hence maximizing battery life. The battery makes up most of the cigarette, and can be recharged using the USB port of electronic devices or with a wall charger. Such a battery will typically last anywhere between 4 and 6 hours, depending on the user’s smoking habits. It is common practice for a user to have two e-cig batteries, one left to charge while the other is being used. When the smoker sucks the e-cig, its tip lights up just as would be expected on a normal tobacco cigarette.

E Liquid

The electronic cigarette e-liquid, smoke juice or e-juice contains the desired nicotine level plus flavoring. Propylene Glycol is the third primary agent, used to create the smoke effect upon heating. As this e-cigarette liquid is heated, the nicotine is introduced into the smoker’s body in a similar way to a normal tobacco cigarette. This company is a trusted electronic cigarette company that produces a wide range of flavors to suit the customers’ needs.

Cartomizers

The e-juice, smoke juice or e-liquid is contained inside the e-cigarette cartilage, which has an appearance similar to that of a normal cigarette filter. Traditionally, e-cigs utilize a separate atomizer and cartilage that forces the user to maintain the separate atomizer and replace it regularly. However, nowadays there are disposable atomizers built right into cartilage of the e-cig, known as cartomizers. Old and unwanted atomizers are discarded together with spent cartomizers. This ensures the smoker’s e-cigarette experience will not be compromised by grimy or old atomizers.
