The headlines were startling: “E-cigarette Use Among Middle and High School Students Skyrockets, CDC Data Show,” from the Washington Post. And this from U.S. News & World Report: “Democratic Senators Pounce on E-Cigarettes After CDC Study Shows Teen Use Spike.”
E-cigarettes, for those who don’t know, are battery-powered devices that look like cigarettes, but don’t burn tobacco. Rather, they deliver nicotine, flavor, and other chemicals in the form of a vapor. The recent media storm was prompted by a report by the US Centers for Disease Control and Prevention that found the percentage of high school students who said they had used one jumped from 4.7 percent in 2011 to 10 percent in 2012. Use also doubled among middle school students, according to the CDC. The report raised anew concerns about the long-term effects of these tobacco products. On Tuesday, 40 state attorneys general sent a letter to the US Food and Drug Administration (FDA), urging the agency to regulate electronic cigarettes in the same way it regulates tobacco products.
Meanwhile, around the same time as the CDC report, a small study of smokers published in the journal Lancet added to growing research suggesting that electronic cigarettes are as effective as nicotine patches in helping people quit smoking.
What to make of the conflicting reports? According to Michael Siegel, a School of Public Health professor of community health sciences, the negative effects of electronic cigarettes have been wildly overblown, clouding the important benefits of e-cigarettes as devices to help people quit smoking.
With only about 6 percent of cigarette smokers successful in quitting the habit, and the tobacco industry free to continue its marketing despite tobacco’s known health effects, Siegel is concerned that the government’s focus on the potential harms from e-cigarettes will detract from their benefits to those who want to stop smoking.
Bostonia recently discussed the controversy with Siegel.
Siegel: Well, first, it’s important to point out that this alarming conclusion is premature. There is no evidence that electronic cigarettes are serving as a gateway to a lifelong addiction to nicotine and conventional cigarettes.
There is something that Dr. Frieden didn’t mention. The overwhelming majority of the youths who reported experimenting with e-cigarettes were already smokers. So the fact that these smokers are experimenting with e-cigarettes is not really a problem. The concern would be if nonsmokers were using electronic cigarettes, and then moving on to regular cigarettes. But the prevalence of nonsmokers experimenting with e-cigarettes in the CDC study was only 0.5 percent. Moreover, the study did not document any examples of youth starting to smoke as a result of first trying electronic cigarettes.
While there is every reason to be concerned about the potential for electronic cigarettes to become popular among youth, there is no reason to be alarmed at this point. It is essential that we continue to carefully monitor this. It is also important that the Food and Drug Administration promulgate regulations that will help prevent the use of electronic cigarettes by youth.
We do know that the predominant reason so many people are using e-cigarettes is that they want to quit smoking in order to improve their health. While we don’t have a lot of quantitative studies about the effectiveness of e-cigarettes in smoking cessation, a clinical trial published recently found that e-cigarettes are just as effective as the nicotine patch for smoking cessation. Unfortunately, the e-cigarettes tested were a first-generation product that did not deliver nicotine very well. It is possible that more advanced products could actually surpass the nicotine patch in their effectiveness.
It is certainly reasonable to carefully scrutinize any consumer product like this. However, what I have a problem with is the fact that the FDA has given its seal of approval to the irredeemably toxic regular tobacco cigarettes—while they are doing everything they can to discourage people from switching to the much safer fake ones. That makes no sense from a public health perspective.
There are actually some benefits to having the major tobacco companies become players in the e-cigarette field. For one thing, they have better access to large retail outlets, and it is possible that their entrance into the market may greatly expand the access smokers have to these products.
In terms of marketing practices, it is essential that the FDA allow companies to tell the truth about the intended use of these products—that they are intended to be used for smoking cessation. That would avoid the need for companies to resort to some sort of glamorized marketing campaign that glorifies smoking behavior.
It is very true that nicotine is not the main component of the tobacco smoke that is responsible for most of the adverse health effects. Because electronic cigarettes deliver nicotine without most of the tens of thousands of other chemicals—and without the more than 60 known carcinogens—it is clear that electronic cigarettes are much safer than tobacco cigarettes.
The scientific research conducted so far suggests that electronic cigarettes are much safer than regular cigarettes, and that in particular, they carry a greatly reduced risk of lung cancer, other cancers, and chronic obstructive lung disease. Evidence presented just recently suggests that they also likely present a lower risk of heart disease.
We need more research to understand whether there may be long-term adverse effects. But what we can say for sure is that they are much safer than the real cigarettes.
I have been following the issue of electronic cigarettes since they entered the US market several years ago. My interest was piqued by the response that these products received from public health and antismoking groups.
Rather than embracing these products as a potential way to get thousands of smokers to quit smoking, antismoking groups have attacked these products and discouraged smokers from quitting by using them. This is so contrary to the principles of public health that it caught my attention—and I continue to be puzzled by this inane public-health response.
The only hypothesis I have come up with is that the ideology in the antismoking movement is so strong that the very thought of condoning a behavior that looks like cigarette smoking is just something that these groups are not capable of doing—even though it is likely saving the lives of thousands of ex-smokers.
