E-cigarettes should be regulated

They pose many risks for tobacco control and health, and any possible benefits are few and uncertain

As reported in this issue of the MJA,1 Australia, with the world’s lowest rates of smoking among adults2 and adolescents,3 is seeing nascent, modest growth in e-cigarette use, despite having some of the strongest restrictions on their marketing and sales. Manufacturers, now including all major tobacco corporations, have spent large sums publicising their brands, using tactics that have promoted cigarettes so successfully, but boosted by the added reach of the internet. They are ahead of the regulatory curve, adopting imagery, messages and tactics prohibited in cigarette promotions, such as the sponsorship of youth events.4 They have spiced their products with a bewildering array of flavourings that in many countries would be illegal in cigarettes, and have garnered vocal support from those who see any restriction on the use of e-cigarettes by governments as a threat to individual freedom. Some aspects of these developments are, however, surprising.

"E-cigarettes have at least two distinct roles. The first is as products that may assist in smoking cessation, [...] Second, they are a means for the tobacco industry to circumvent restrictions on promoting both their image and their tobacco products."
These are two roles that may apply to public health officials, but less so to the public. What about the role of e-cigs for those who use them? One of their roles is certainly enjoyment and stress relief without the danger and guilt of tobacco cigarettes.
It would be nice to have access to pleasurable stress relievers like fine wine and quality food. To come home from a job that is secure, in a position that affords respect, to a comfortable home you can afford, would be great. However this is not the case for a large percentage of everyday people for whom life is an endless struggle to keep your head above water.
For the rest of us it's a beer and a cigarette in your back yard, while trying not to think about the fact that you won't have enough to pay the bills this week, your boss is a tyrant and your work is back breakingly dull. Your kid is autistic but you don't have the money for a private school with extra support. You try not to worry about what will become of him and all the things that could go wrong, and you light another cigarette because there are so few moments of pleasure in your life. In this moment at least, there is some relief.
What if your 14 year old gets caught smoking at school? Not only do you fear they will end up as addicted as you are but on top of that is the crushing guilt that you caused it by setting a bad example. Then an overwhelming feeling of powerlessness in the face of the inevitability of it all.
The stresses on low income people are many. For working class people their jobs are unsatisfying and low paid. The pleasures available to them are few and of low quality, and yet the need for them is greater due to the pressure of more complex stressors. The fear of possible health problems at some point in the future pale against the fears of today, and every day.
This is my world and I don’t feel the people who wrote this article understand me at all. They don’t speak for me, and in the case of e-cigarettes they certainly don’t appear to have my best interests in mind. As the quote above suggests, what they seem most concerned with is a war with tobacco companies and a preoccupation with making my few pleasures a medical matter.
What public health could do to help me, the public, is to give accurate information about the potential risks and benefits of e-cigarettes, especially compared to tobacco cigarettes. To allow myself, and my teenage kids, the option of a safer alternative. Despite my lack of academic credentials, I am actually capable of assessing risk and making informed choices. They may not be the choices you would make for me, but you don’t have to live my life.

In the sometimes peculiar world of e-cigarette discourse, it often seems that those who recommend caution regarding their use and de-regulation are required to provide volumes of evidence that disprove their value and safety. Proponents, on the other hand, are required only to make unsubstantiated claims for the efficacy of e-cigarettes in smoking-cessation and harm reduction. As pointed out in this editorial for example, Public Health England’s widely-reported claims regarding e-cigarettes are based on extremely limited 'evidence'.

A key catchphrase of e-cigarette proponents is that people smoke for the nicotine but die from the smoke. But as noted above, there is growing evidence that suggests nicotine promotes tumours, is genotoxic, and linked to a range of cancers [1].

Ongoing uncertainty regarding the effectiveness of e-cigarettes, and their potential harm, coupled with the tobacco industry’s growing acquisition of new addictive products, provides a powerful argument against de-regulation in Australia pending further analysis.

The primary ingredient of concern to those who wish to see e-cigarettes banned is the propylene glycol vapor, which has been studied for over 70 years.

I recently came across a document titled, “Reregistration Eligibility Decision For Propylene Glycol and Dipropylene Glycol“, which was created by the United State Environmental Protection Agency (EPA).

This quote caught my eye:

Propylene glycol and dipropylene glycol were first registered in 1950 and 1959, respectively, by the FDA for use in hospitals as air disinfectants. (page 4, paragraph 1).

I had shared the summary of research that had been done in 1942 by Dr. Robertson regarding the antibacterial properties of vaporized propylene glycol, but I had never heard that the FDA wound up approving it for the purpose of an air disinfectant in hospitals.

Indoor Non-Food: Propylene glycol is used on the following use sites: air treatment (eating establishments, hospital, commercial, institutional, household, bathroom, transportational facilities); medical premises and equipment, commercial, institutional and industrial premises and equipment; (page 6, paragraph 2)

Method and Rates of Application


Air Sanitizer

Read the directions included with the automatic dispenser for proper installation of unit and refill. Remove cap from aerosol can and place in a sequential aerosol dispenser which automatically releases a metered amount every 15 minutes. One unit should treat 6000 ft of closed air space… For regular, non-metered applications, spray room until a light fog forms. To sanitize the air, spray 6 to 8 seconds in an average size room (10'x10'). (page 6, paragraph 6)

My point here is we were all born in a hospital that uses basically ecig juice to disinfect the atmosphere and everywhere else we've been since birth! Why the attacks.

On Second hand smoke;

The Chemistry of Secondary Smoke About 94% of secondary smoke is composed of water vapor and ordinary air with a slight excess of carbon dioxide. Another 3 % is carbon monoxide. The last 3 % contains the rest of the 4,000 or so chemicals supposedly to be found in smoke… but found, obviously, in very small quantities if at all.This is because most of the assumed chemicals have never actually been found in secondhand smoke. (1989 Report of the Surgeon General p. 80). Most of these chemicals can only be found in quantities measured in nanograms, picograms and femtograms. Many cannot even be detected in these amounts: their presence is simply theorized rather than measured.
