Electronic cigarettes or e-cigarettes are often characterized as smokeless nicotine delivery systems allowing users to conveniently “light up” in places where the use of traditional smoking products may be prohibited. Because e-cigarettes and e-cigars vaporize a solution of liquid nicotine rather than burning tobacco they are sometimes called safer cigarettes. E-cigarettes are available in several popular styles. Pen style devices can look like a writing instrument and be attractively decorated. Tubular or tube style smokeless devices look more like actual cigarettes or cigars. In some countries where nicotine itself is regulated, health authorities may govern the use and sale of e-cigarettes.

While styles of electronic cigarettes may differ, all smokeless e-devices share a common broad design and similar component parts. A battery and a small circuit board are triggered manually or by inhalation. A heating element usually called an atomizer turns tiny amounts of nicotine solution into vapor. A disposable mouthpiece or cartridge contains a reservoir, an inner cup for a liquid nicotine solution and serves as a suction device for the smoker. A colored LED indicates when an e-cigarette has been activated. E-cigarette batteries are rechargeable, often via a USB connection. Liquid nicotine solutions can be flavored to mimic the taste of a particular tobacco blend or may contain menthol.

A wide array of electronic cigarettes and cigars are now available. Here are several popular models.

The E-Cigar

E-cigars replicate the general shape and feel of a traditional small cigar. Like most cigars, an e-cigar is thicker than a cigarette. Manufacturer Shenzhen Kanger Technology Co., LTD offers several models of the e-cigar, as do other makers. E-pipes are also available.

Pen Style E-Cigarettes

Pen style e-cigarettes don’t attempt to look like the real tobacco product and come in a wider array of lengths and designs; some beautifully decorated like the cigarette holders of the pre-filter era. The Classic from maker Janty, and the Janty Kissbox Classic offer an elegant approach to the pen style unit.

Tube Style or E-Mini Cigarettes

Tube style electronic cigarettes have the general look and feel of your favorite brand. The most popular of the tube style units may be the Mini-E Cigarettes from First Union Technologies. With cartridges available flavored like Marlboro or Camel a tube style e-cigarette is the best choice for a traditional smoker attempting to cut back on tobacco use.
