The e-cigarette industry got some good news this week: A
survey of almost 6,000 smokers in Britain trying to quit found that
those who used electronic cigarettes were more likely to stop using
smoking tobacco than those who used over-the-counter quitting aids or
had no help at all.

While surely welcome news for fans of vaping, these survey results are not the kind of evidence that proves e-cigarettes are effective quitting aids and would let the industry market them as such. For that, regulators want to see rigorous, randomized control trials that compare e-cigs with placebo treatments. E-cigarettes are also an evolving technology, with varying formulas and designs that may have different effects on users. And the research doesn’t address whether smokers relapse more when using e-cigs than other quitting methods.
Scientists also haven’t established what risks e-cigarettes might pose to long-term users. It’s impossible to know how these products will affect people over decades, because the products are less than 10 years old.
Other risks associated with e-cig use: They occasionally explode, and children or pets may accidentally consume the poisonous liquid if it’s left unsecured.

While vaping is widely believed to be safer than inhaling tobacco smoke, it’s “not safer than just breathing clean air,” as Dr. Richard Hurt, former director of the Mayo Clinic’s Nicotine Dependence Center, said in a recent interview.
Other research in the U.S. suggests that smokers’ perception that e-cigarettes are less harmful is declining.
Still, many people report anecdotally that e-cigs help them trade a habit known to be deadly for one presumed to be less dangerous, even when other approaches failed. To the extent that e-cigs help people quit inhaling tobacco, the study says, “e-cigarettes may substantially improve public health because of their widespread appeal and the huge health gains associated with stopping smoking.”
