New study uncovers false claims on e-cigarettes

A new research has cast doubt on the safety of e-cigarettes and their use as a smoking cessation aid.


In a major scientific review of research on e-cigarettes, University of California, San Francisco scientists found that industry claims about the devices are unsupported by the evidence to date, including claims that e-cigarettes help smokers quit.

The devices, which are rapidly gaining a foothold in popular culture particularly among youth, are marketed as a healthier alternative to tobacco smoking, as an effective tool to stop smoking, and as a way to circumvent smoke-free laws by allowing users to “smoke anywhere.”

Researchers said the ads often stress that e-cigarettes produce only “harmless water vapour.” But in their analysis of the marketing, health and behavioural effects of the products, which are unregulated, the scientists found that e-cigarette use is associated with significantly lower odds of quitting cigarettes.


They also found that while the data is still limited, e-cigarette emissions “are not merely ‘harmless water vapour,’ as is frequently claimed, and can be a source of indoor air pollution. The long-term biological effects of use are still unknown, the research authors said. The authors analysed 84 research studies on e-cigarettes and other related scientific materials.

They concluded that e-cigarettes should be prohibited wherever tobacco cigarettes are prohibited and should be subject to the same marketing restrictions as conventional cigarettes. E-cigarettes deliver a nicotine-containing aerosol popularly called “vapour” to users by heating a solution commonly consisting of glycerin, nicotine and flavouring agents. E-liquids are flavoured, including tobacco, menthol, coffee, candy, fruit and alcohol flavourings.

Despite many unanswered questions about e-cigarette safety, the impact on public health, and whether the products are effective at reducing tobacco smoking, e-cigarettes have swiftly penetrated the marketplace in the US and abroad in both awareness and use, researchers said.

The study was published in the journal Circulation.
