Essentially, these regulations freeze the current market of electronic cigarettes, or at least of those electronic cigarettes which were most like the products already on the market in 2007.

Not only does this column provide bad medical advice, but the advice itself is based on misinformation. For example, the article claims that e-cigarettes have been shown to be a gateway to smoking: "Most dangerous of all is the appeal to children. Vapor is less irritating than smoke, and comes in flavors such as bubble gum, cola and chocolate. Some children who would not try regular cigarettes will be tempted by e-cigarettes. As soon as they start, they will become addicted to nicotine and suffer from the health effects and expense of that addiction. Others who start with e-cigarettes will go on to use real cigarettes, and face the deadly diseases they cause."

The study concluded that: "e-cigarettes generate smaller changes in lung function but similar nicotinergic impact to tobacco cigarettes."

Sadly, the truth is that the one lying to and deceiving the public is the American Lung Association. Most electronic cigarette companies are honestly and correctly informing their customers that these products are safer than cigarettes and that they may be helpful to some people in getting them off tobacco cigarettes. These are demonstrably truthful statements.
