In recent years, electronic cigarettes have become increasingly popular among smokers who want to find a tobacco alternative that doesn’t contain tar, carbon monoxide and the other harmful chemicals in cigarettes. However, if you are new to electronic cigarettes, you may understandably have some concerns about whether switching to e-cigarettes would simply be a matter of exchanging one harmful product for another. In fact, with the exception of nicotine, you probably already consume the ingredients in electronic cigarette e-liquids on a daily basis. To alleviate the concerns of customers, many companies are now publishing the ingredients that they include in their e-liquids. You may find it helpful to purchase from one of these companies if you are concerned about the harmful chemicals an e-liquid might contain. These are the most common ingredients that you are likely to find in a USA-made e-liquid.
eCig Ingredient 1: Propylene Glycol
Propylene Glycol is the same liquid used in smoke machines; at relatively low temperatures, it turns quickly to vapor. It is a clear liquid that has almost no smell or taste, and you can commonly find it as an additive in food products to emulsify ingredients and prevent drying. Propylene glycol is also an excellent carrier of flavors, allowing electronic cigarette e-liquids to taste like tobacco, menthol and a variety of other flavors. The United States Food and Drug Administration considers propylene glycol “generally recognized as safe,” meaning that it is not known to have any harmful effects.
eCig Ingredient 2: Vegetable Glycerin
Vegetable glycerin is a clear, thick liquid that has a slightly sweet flavor on its own. Like propylene glycol, it is used in food products for moisture retention and emulsification. It is also used as a thickener. Because some people may be allergic or sensitive to propylene glycol, vegetable glycerin is used as an alternative base in some e-liquids. Although vegetable glycerin doesn’t carry flavors as well as propylene glycol, it is much thicker and creates thicker vapor as a result. Because some electronic cigarette users find thicker vapor to be more satisfying, many e-liquid companies use a ratio of approximately 80 percent propylene glycol and 20 percent vegetable glycerin in their e-liquids to create products with a good combination of flavor and thick vapor. The Halo G6 and Volcano Inferno use e-liquids composed of both propylene glycol and vegetable glycerin.
eCig Ingredient 3: Nicotine
Nicotine is the primary addictive substance found in tobacco, and its presence in e-liquid allows a smoker to switch to electronic cigarettes without experiencing withdrawal symptoms. Although nicotine is extracted from tobacco plants, the nicotine used in e-liquid is pharmaceutical-grade and extremely pure. Out of all the ingredients in e-liquid, nicotine is the one with the most potential to cause harm. However, the risks of using nicotine in this fashion should be similar to the risks associated with nicotine replacement products such as gum and patches.
eCig Ingredient 4: Natural and Artificial Flavorings
E-liquid manufacturers use food-grade flavorings to create approximations of tobacco. When combined with nicotine, an e-liquid containing a combination of spicy, nutty and rich flavors can closely resemble the flavor of a real cigarette. E-liquids may also contain menthol, which is usually extracted from essential peppermint oil. Some companies also sell e-liquids that are not designed to resemble the flavor of tobacco. These e-liquids are available in spice, beverage, fruit and dessert flavors, adding to the potential appeal for a smoker looking for a change.
