"I smoked cigarettes for 50 years, two packs a day. The first day with an E Cigarette, i was able to stop the cigarette habit completely. After 23 months of vaping, i can breathe again, taste again, run again, sing again. I have lowered my nicotine from 36 mg in a cigarette to 3 mg in my ECigarette. And within the month i will be at 0 mg. my husband and friends comment on the lack of smell produced by the vapor and if they do notice it is a fruit flavored scent. Due to the lack of burning, there is not a second hand smoke issue. The smoke lingers in the air but the vapor dissapates quickly. Unless i blow it directly at you, it is not a health issue. Most countries now have done enough research that they are seeing vaping as good deterrent to smoking. Except our own which is listening to big tobacco and the pharmacutial companies who are losing millions of customer dollars. My concern if big tobacco takes over the ecig business what chemicals will they add to keep pepole addicted to their products like they did to the tobacco leaf." 4 stars by

E-Cigarettes and the Challenge of Public Health

Biggest Problem

Recently, I was sitting in a meeting with some people, and during a lull in the conversation, they asked me:

“Hey, you’re in public health. What is the biggest problem you face?”

I paused. That’s a tough question. The Western World is facing a number of issues ranging from social to political, and include areas such as increased inequality, an aging population, rising student debt and the issues associated with young people starting their careers already owing six figures to a bank or their government, among other things.

However, while others might pick the more “sexy” health issues of the day such obesity or cancer, I’m going to go off the board. I think the biggest problem public health faces is Time. I’ll explain what I mean through e-cigarettes.

What are they?

E-cigarettes use battery powered vaporizers that turn a liquid solution into an aerosol that can be inhaled, similar to smoking.

The solution can include a range of ingredients, but most importantly, do not (necessarily) include nicotine. Nicotine itself forms one of the addictive elements of conventional cigarettes, and so it has been proposed that these could be used as quitting aids by slowly reducing the dependence people have for nicotine. Plus, in addition to a chemical dependence, there’s also a behavioral element to smoking. My friends who have tried to quit, struggle with the behavioral cues associated with smoking: having a cigarette with coffee, or while driving to work, or after a long day to unwind.

Those environmental cues can be as effective at creating a desire for smoking as the chemical component. For those trying to quit, there are thus multiple issues that need to be addressed. This can be where e-cigarettes become useful.

Critical Delay

As a quitting aid, e-cigarettes can help step people down from the chemical addiction with lower and lower doses of nicotine,

ultimately culminating in no nicotine, as well as provide a way for them to get that feeling of smoking without “all the bad stuff.” Or at least, that’s the theory. However, since these devices are so new, there isn’t much, if any, research to substantiate this (yet).

EDIT: This review bit.ly/1BqAEgx and this study bit.ly/1xFvej7 as pointed out to me on Twitter, reported reductions in conventional cigarette use when e-cigarettes were used. This is a promising finding, and is something public health professionals can use to build programming, and advocate for e-cigarette use (especially if more studies can confirm this experimentally, as well as evaluate them for long term).

However, both highlight the crux of this piece, as these were both only published this year.

That delay between the introduction of e-cigarettes, and data suggesting that they can be useful for cessation, is an important issue within public health.

Flavor Factor

Now, the liquid that gets vaporized comes in a number of different types, but the one that is the most concerning are the flavored varieties.

While the nicotine component could, potentially, help people, the flavoring is a completely separate concern and serves no purpose other than to make the product tastier and more enticing. This is a particular concern, especially among our youth. Dr Leia Minaker and colleagues did a study out of the University of Waterloo and found 52% of Canadian students who identified as smokers in Grades 9 through 12 used flavored tobacco products. This was even higher among smokeless tobacco users (70%) (1*). So not only do we know kids are drawn to these products, we know they’re likely to be using the flavored versions of them if they do use them.

Flavors such as strawberry, “great grape” and juicy peach are all available for consumption

The Problem

Now herein lies the problem. We know there are concerns with e-cigarettes. We know there are health problems that are a direct result

of smoking, and we know that this is targeting children who will (most likely) become smokers as they grow up. However, we need evidence to make such claims. Tobacco companies follow the law – maybe not the spirit of it (that’s up for debate), but the, written down, carved in stone, law. So if you say you can only have a certain amount of nicotine in a product, they’ll put in less than that. They won’t open the floodgates to lawsuits and litigation.

Marketing

However, due to the lack of regulations on e-cigarettes, suddenly there is an open market available, and so they put energy

into marketing them, and selling them to the market that can legally buy them (including children). On top of this, kids will market them to each other. Cigarettes have always had an allure to them, both in terms of making you seem “grown up,” as well as a “rebel.” Those are things that youth crave as they navigate the tempestuous waters of elementary and high school.

Just because there isn’t evidence they can’t harm you, doesn’t mean they won’t.

Safe - or not?

Indeed, the FDA initially came out against them, banning them back in 2010, but, this was overturned soon afterwards,

ostensibly due to the lack of evidence saying they would cause harm. Why the fact that there was no evidence to the contrary wasn’t a concern, I don’t know. Research is slowly coming out now that is highlighting the risks of e-cigarettes. In fact, increasing the voltage from 3.2V to 4.8V results in a 4 to 200 fold increase in the amount of formaldehyde, acetaldehyde, and acetone – to levels comparable to that of a regular cigarette (2*).

It All Takes Time

However, this all takes time. Performing these studies, following up users of these products, and determining if they can be used

as a quitting aid, is all required to determine whether or not this is a substantiated claim. It’s not just the research that has to be performed – the law then has to be amended. The EU decided right off the bat to restrict sales to minors, well before research was available. Even then, it took a bill, proposed on the 19th of December 2012, until February 2014 to finally be approved. Thus, e-cigarettes point out a massive flaw in public health, which is ironically its biggest strength. The fact that we take time to collect data before making a decision is essential, but it means we’re waiting months and even years to collect the evidence, analyze the data, write and publish the reports that we can then present to policymakers to say “hey! Fix this!”

The Time Delay

And it doesn’t stop there. We’re then waiting for policymakers to propose the idea, have them vote on it, fight any backlash

from industry or the public (and there will be backlash from the $1.2 billion e-cigarette industry). On the flip side, it means that if there are benefits to use – maybe for those trying to quit – we can’t claim that either. We’re stuck in a holding pattern until the data comes back with an answer.

Currently, while there might be some good reasons to have e-cigarettes available, there’s no evidence to support that claim. There is, however, a growing body of research is showing that there are drawbacks to them. In the meantime, people are freely using them and suffering adverse health effects associated with their use.

That time delay, between a product being introduced and public health being able to tackle it, is one of the biggest problems that public health faces.
