Where There’s Vapor, Is There Fire? We Need Evidence on E-Cigarettes

One thing that is known about electronic cigarettes: they’ve become a serious business in the United States.

Although e-cigarettes represent only a tiny percentage of the U.S. tobacco market, the industry is growing.

The number of people currently “vaping” has increased substantially over the last few years, with sales of nearly $2 billion in 2013.

Some analysts predict that this could grow to $10 billion by 2017 and eventually overtake sales of conventional cigarettes.  It’s worth noting that the industry is maturing without much in the way of oversight or regulation.

We also know how e-cigarettes work—mechanically speaking. Using a battery-powered heating element, they convert liquid nicotine (sometimes flavored with food additives) into a vapor that users then inhale or “vape.”

This unique system delivers nicotine without the cancer-causing and other harmful elements associated with burning tobacco.

Unfortunately, that’s where a lot of the certainty ends. Currently, evidence for the safety, harmfulness, utility, and addictiveness of e-cigarettes is lacking.

The questions that research needs to answer, however, are clear as day—particularly since business is booming.

Are E-Cigarettes Bad for You?

Some of the food additives that flavor e-cigarette vapor may be dangerous when inhaled; the long-term health effects of inhaling the vapor are unknown. And of course, e-cigarettes still deliver nicotine, the main addictive ingredient in cigarettes and other tobacco products.

Nicotine from e-cigarettes could have detrimental effects on cardiovascular health and may impair breathing among those with already compromised lung functioning.


The FDA Center for Tobacco Products is concerned enough that it is collecting reports of adverse events among e-cigarette users and funding research on the potential toxicity and addiction threat of e-cigarettes.

Can E-Cigarettes Help You Quit?

E-cigarettes may function like other FDA-approved nicotine replacement products (e.g., patches, gum), acting as a safe and effective means for helping cigarette smokers reduce their consumption or quit altogether. Uncontrolled clinical reports and patient anecdotes suggest that cigarette smokers have successfully used e-cigarettes to both ends.

However, the first large study testing this showed almost the opposite: Smokers who used e-cigarettes to quit were no more likely to succeed over the long term than smokers who used inactive placebo e-cigarettes.

Other clinical trials testing the efficacy of e-cigarettes for smoking cessation are ongoing, but existing data are far too sparse to recommend e-cigarettes as a first- or even second-line medication for smoking cessation.

What About Marketing?

There is considerable alarm over the increasing use of e-cigarettes among adolescents. Based on established relationships between exposure to cigarette advertising and adolescent smoking, exposure to increasingly pervasive e-cigarette advertising and accessibility of e-cigarettes in retail stores may be associated with this uptick.

Use of e-cigarettes could be a gateway to cigarettes or other tobacco products.

However, there is no evidence that exposure to advertising and promotion for e-cigarettes prompt use among anyone. And there’s no evidence for a gateway effect—a historically controversial topic, regardless of the substance or substances being abused.

Of course, the billions of tobacco industry dollars devoted to advertising and promoting cigarettes have contributed to increases in cigarette smoking among young people. An extensive body of research supports this. But relying on this for evidence of the dangers of e-cigarette advertising and accessibility is not sound science.

What’s Next?

The bottom line is that policy should never get ahead of science. Anecdotal reports, hearsay, and “hair-on-fire” concerns aren’t a sufficient foundation for building policy.

The FDA Center for Tobacco Products is well aware of this and is committed to funding research that seeks more definitive answers to the many unanswered questions about the safety, harm, and even potential clinical utility of e-cigarettes.

Soon there will likely be a ruling from the FDA on how to best regulate e-cigarettes. Local communities and organizations are enacting bans on use. E-cigarette manufacturers are mobilizing for war.

Expect a long fight with battle lines drawn over scientific ambiguity and lack of evidence—at least until the body of research matures.

I would like to see a study on how e-cigarettes effect dental health like gum disease http://www.progressivedental-ellenlimdds.com/

E-cigarette in any way is better in comparison to tobacco cigarette as it has lots of benefits like it saves money, its smoke has less effect on our health in comparison to tobacco cigarette, it is also environment friendly.

e-cigarettes certainly a great alternative to smoking, though I still doubtful about its health benefits. I mean nicotine is not good for your health and e-cigarettes makes you body to consume nicotine whenever you use it.

TVECA:

“What we don’t claim:

We make no claims that the electronic cigarette is safer than tobacco cigarettes or do we make any claims that the electronic cigarette is a stop smoking or cessation product.”

The TVECA (Tobacco Vapor Electronic Cigarette Association) is a nonprofit organization dedicated to creating a sensible and responsible electronic cigarette market by providing the media, legislative bodies and consumers with education, communication and research. We promote responsible and logical regulation. We feel that fear mongering with inaccurate information and/or data is not the way to promote this process.

“Currently, evidence for the safety, harmfulness, utility, and addictiveness of e-cigarettes is lacking.”

Cigarettes were the delivery system for the addictiveness of nicotine. E-cigs are just another system for delivering the same addictive drug.

I hope the no smoking bans for cigarettes are held in place for the E kind.

Is anybody working on developing a prototype that does the same thing for medical marijuana – in theory the delivery mechanism would work in the same way

This is the same BS remark that everyone in the news media retreats to. Why don’t they all do some research and they will find that dozens of tests have already been done on e-cigs. Ever heard of Google just do a search. I smoked for over 20 years and switched to e-cigs over a year ago and never looked back and I never felt better.

If we’re having this much trouble making good policy here in the U.S., what are other countries (ie. France, South Korea, China) doing? Not making e-cigs a medical device, I hope…

smoker turned e-smoker

I used to be a smoker. But now I use e-cigarettes. No disgusting smell and they come in different flavors. They help with my headaches and keep me stress-free.

So while everyone is battling over policy and regulation and uncontrolled trials, what should I be considering in the here and now? How many times a day is okay? A week?

Can anyone tell me anything??
