Across the U.S., more than one in five (21 percent) adult tobacco users have stopped smoking for the first time because of vaporizing tobacco products. These results, released today by the Centers for Disease Control and Prevention (CDC), contradict the myth that vaporizers and e-cigarettes are a gateway to smoking for youth. The survey also found that the majority of those switching from smoking quit entirely.

“These results suggest that more than 25 million adults and children have kicked the habit because they use e-cigarettes or vapor products,” said Dr. LaQuandra Nesbitt, director of CDC’s Office on Smoking and Health. “But more work is needed to make these products less dangerous and prevent young people from starting to smoke in the first place.”

These results from the Behavioral Risk Factor Surveillance System — the nation’s largest e-cigarette surveillance survey — were based on a representative sample of 39,700 adults (aged 18 and over) in July 2017.

E-cigarettes are battery-powered devices that vaporize a flavored vapor, such as menthol, among other options. Some contain nicotine, the active ingredient in cigarettes. It can eventually lead to addiction. Some vaping devices also contain other chemicals, including flavoring, often added for marketing purposes.

Some studies have reported that e-cigarettes are less harmful than traditional cigarettes, despite their claim to be safer. A study released in 2015 found that the most popular flavored e-cigarette “wax,” when compared to tobacco cigarettes, was lower in tar and other toxic chemicals but higher in flavor. A 2018 study also found that e-cigarettes had fewer toxicants than regular cigarettes. Some studies have shown that e-cigarettes do not threaten cancer risk in long-term users. Other reports show the possible effect of e-cigarettes on lung health.
