The reason e-cigs were developed is necessary to understanding what electronic cigarettes are. For decades smokers could indulge their habit in any setting without interference. The tolerance for cigarette smoking has undergone a drastic change in recent years.

Increasingly, tobacco users find themselves ostracized in public areas and relegated to feeding their habit outside public buildings and only in certain designated smoke filled rooms in airports. The condemnation of tobacco has spread to bars, restaurants, theaters and everywhere else people gather as the dangers of second hand smoke have become public knowledge.

The e-cigarette was introduced to the marketplace in 2003 as an alternative for smokers. This personal vaporizer delivers flavor and fulfills the need to nicotine yet does not cause a negative affect on those around you. Shaped like a tobacco cigarette or a ball point pen initially, models are now available to also resemble cigars and even pipes.

E-cigs are reusable although some come with disposable components. The best selling products are the automatic style where vapor is delivered on demand when the user applies draws on the mouthpiece.

A sensor in the mouthpiece of an automatic e-cig detects air flow when the user inhales and activates a heating element in the battery section. The nicotine solution in the mouthpiece is vaporized by the heat from the battery section which has a LED light at the tip. Originally, the LED lights were always red or orange to resemble a burning cigarette but the lights can now be any color the user chooses.

On the manual models the user must press a button to activate the heating element and release a vapor. Manual and automatic style use the same electronic circuits and rechargeable batteries in their delivery systems.

The tip of the mouthpiece may be round like a cigarette or shaped like the plastic mouthpiece of some cigars. Absorbable material in a small cup located in the mouthpiece is saturated by the user with an e-liquid that is a flavored product that contains nicotine. The common name for the mouthpiece is “cartridge” and it may be refillable with the e-liquid or may be a disposable cartridge that is simply replaced when the solution has been used. The heating element is the “atomizer” and located in the battery section of the e-cig. Heat is used to vaporize the e-solution allowing the user to inhale the vapor.

Electronic cigarettes are nothing more than a delivery system for nicotine. A wide variety of flavors of e-liquid are available from suppliers and users can choose from one of several levels of nicotine concentration. The dosage of nicotine resembles various strengths of tobacco products such as regular, light or extra-light. If you have wondered “what are electronic cigarettes” the answer is they are an excellent alternative to tobacco that provides nicotine without affecting your health or the safety of those around you.
