How Does E-cigarette Work?
E-cigarette performs similarly to traditional smoking. It looks, feels and tastes like a cigarette or cigar, and delivers all the pleasures of smoking, without all the problems. The secret to what makes E-cigarette better than traditional smoking is what is inside this revolutionary new product.

The non-flammable E-cigarette is driven by modern microelectronic technology, a small rechargeable battery and a unique, safe replaceable cartridge containing water, propylene glycol, nicotine, a scent that emulates a tobacco flavor and a membrane to suspend the ingredients.

When using E-cigarette, the act of inhaling or smoking it produces the tactile and craving satisfactions traditional smokers seek, and triggers a vaporizing process that releases a simulated smoke that is actually a vapor mist that harmlessly evaporates into the air within a few seconds.

How do the ingredients compare to those in common smoking products?
The number of ingredients in E-cigarette and the outcome of those ingredients when used are vastly different and infinitely safer than those found in traditional cigarettes and cigars.

E-cigarette contains only water, propylene glycol, nicotine, a scent that emulates a tobacco flavor and a membrane to suspend the ingredients. None of these ingredients are considered cancer-causing agents. The Food and Drug Administration deems propylene glycol safe. Nicotine itself is not believed to have toxicological effects, offers some therapeutic uses and can be found in pepper, tomato, eggplant and potato.

Cigarettes and cigars, meanwhile, commonly contain tobacco, hundreds of additives, nicotine, glue and paper, which when ignited, according to the Centers for Disease Control, harm nearly every organ of the body, and cause cancer, and cardiovascular and respiratory disease.

What is propylene glycol?
Propylene glycol is a commonly used organic compound that is recognized as generally safe by the Food and Drug Administration. It is used in food coloring, and flavoring, as an additive to keep food, medicines and cosmetics moist, and in machines that simulate smoke. In E-cigarette, propylene glycol functions to provide the vapor mist that looks like smoke and to suspend flavor.

What is nicotine and how does it affect the body?
Nicotine is an alkaloid found in certain plants, predominantly tobacco, and in lower quantities tomato, potato, eggplant and green pepper. When absorbed in small amounts, whether from cigarettes, cigars or E-cigarette, nicotine can cause stimulation, a feeling of relaxation, calmness, and alertness. The effects of nicotine can last from minutes to hours.

The carcinogenic properties of nicotine in a standalone form (i.e., separated from smoking or chewing tobacco) have not been evaluated by the International Agency for Research on Cancer, however current available literature indicates that nicotine in standalone form does not promote the development of cancer in healthy tissue and has no mutagenic properties.
