Ban the Snus Ban



The European Union last year confirmed its irrational ban on smokeless tobacco, denying smokers safer products that are widely used in Sweden.  In October, shortly before the European Parliament extended the ban by supporting the revised EU Tobacco Directive, Europe’s leading tobacco research and policy experts expressed their support for tobacco harm reduction in a letter to the United Kingdom’s Parliamentary members and to UK Secretary of State for Health Jeremy Hunt (originally published here).  Their argument, brilliantly stated, should resonate with U.S. policymakers and public health practitioners.

Dear Mr Hunt,
Re: Tobacco Products Directive and snus
We are writing to you as independent public health specialists to react to your letter to UK MEPs on the Tobacco Products Directive. We were disappointed that you declared support for banning snus outside Sweden, and believe the justification given is inadequate.  The position statement[1] argues that we would take a ‘backward step for public health by relaxing a ban on an existing category of tobacco’.  This reasoning is weak unless you plan an imminent ban on cigarettes.  In reality, it simply assists the most harmful form of tobacco, cigarettes, by banning a much safer alternative and causes ill-health by denying this option to smokers.  We disagree with the policy of banning snus and regard it as unscientific, unethical and far more likely than not to contribute to additional death and disease from smoking. This letter briefly explains why there is no justification for the ban, and why many leading experts have called for it to be lifted, for example in a letter from 15 experts to Commissioner Dalli in 2011[2].  Sadly, these well-informed and carefully argued views from public health experts were ignored when the Commission published its proposal for the revised directive in December 2012. In the case of snus, the Department of Health has not followed the logic of its own approach to ‘harm reduction’. The consequence is an unjustified and harmful ban based on a policy-making error made 25 years ago.  We hope this letter is sufficient reason for you to reconsider the issue of the snus ban with an open mind and fresh pair of eyes.

An unjustified ban on snus – misunderstood gateway effects.  Snus has been banned in the EU, other than in Sweden, since 1992.  The original reason for the ban was a fear that it could become a ‘gateway’ to smoking for young people. This risk was only ever hypothetical but the subsequent reality of snus use in both Norway and Sweden shows that it is, beyond doubt, a gateway out of smoking.  Snus is used as an alternative to smoking and as a means to quit. Further, snus is not increasing but rather decreasing onset of smoking in young people.   It is primarily because of snus use that Sweden and Norway have the lowest rates of smoking in Europe, by far.  It is sometimes claimed that snus should be banned because is not 100% safe. However, this misunderstands its impact: the overall effect of snus has been protective and highly beneficial to public health where it is on sale freely.  The original justification for the ban has been overturned by evidence from the real world, and there is now no justification to treat snus differently to any other smokeless tobacco. As with e-cigarettes, there are good reasons to carefully encourage its use as an alternative to smoking for people who cannot or do not wish to quit using nicotine or tobacco. 
Health potential of snus in the rest of Europe.  There has been a remarkable success for public health in Sweden and Norway that deserves more recognition.  According to the most recent Eurobarometer survey[3], adult smoking prevalence in Sweden is just 13%, far lower than the EU average of 28%. Nothing we consume can be 100% safe or pure, but the risks associated with snus use are of the order of 95-99% lower than for smoking[4]. This has resulted in substantially reduced burdens of tobacco-related disease (cancer, cardiovascular disease, emphysema). For example, the rate of lung cancer mortality in Sweden is half that of its neighbour Denmark[5]. Sweden also has significantly lower levels of oral cancer mortality. It is not enough to argue, as the Commission does, that snus is ‘toxic and addictive’: it is a very much less toxic and also less addictive than cigarettes but its effective nicotine delivery still makes it a viable alternative to smoking. This is the well-established idea of ‘tobacco harm reduction’ working for health here in Europe. More data are appended at the end of this letter.
An unethical ban.  When people use snus instead of smoking they are significantly reducing their own health risks, at their own expense, on their own initiative, and with no harm to anyone else.  On what basis can a government justify using the force of European law to prevent them doing this? The consequence, visible everywhere in the European Union outside Sweden, is more smoking and more death and disease than there would otherwise be. Even if a single user somewhere in Britain wished to use it, why should a European Union directive prevent them? Why should the UK wish to prevent someone using it in another country, such as Denmark? We can find no precedent for governments banning much safer alternatives to risky products. This highly irregular policy raises major ethical concerns and implicates the European Union and UK government in causing additional unnecessary harm.

Incoherent tobacco legislation brings the EU into disrepute. The approach to snus policy and legislation rests on a 25-year-old error that officials have refused to accept or correct[6]. There is no credible explanation for why the safest known form of tobacco in the world, snus, is banned when the most dangerous, the manufactured cigarette, is widely available.  No one can explain why smokeless tobacco placed in the mouth and chewed is permitted, but if sucked it is banned. How can a ban be consistent with the principle of free movement of goods, especially when we know the impact of the product is overall beneficial to health where it is not banned? These obvious contradictions disfigure such important legislation. All branches of the legislature have professional and legal obligations to take advances in scientific understanding into account, and this is especially important given the lives at stake.  It is now time face these responsibilities, and to correct the 25 year error behind the ban on snus.
Fixing the snus provisions in the tobacco products directive. There are three main options, which we list in order of preference, with the most strongly justified first.
1.      Treat snus like any other smokeless tobacco. The definitions in the directive can be amended to remove the arbitrary discrimination between snus and other smokeless tobaccos. This would be the simplest and best approach.
2.      Treat snus like a novel tobacco product. Snus products could go through the same process for introduction of novel tobacco products, such as those that heat tobacco, under Article 17 of the proposed directive. Given snus has not been present for at least 20 years outside Sweden, it is reasonable to treat it as ‘novel’.
3.      Allow an exception to the general ban where snus has traditional use. This would allow members states to determine that snus meets a traditional product demand, and to permit it.  
We also advocate a regulatory framework for all smokeless tobacco that would place limits on the toxic contaminants that potentially cause harm. The WHO’s expert group on smokeless tobacco recommended exactly this[7], and the approach is supported by the UK Royal College of Physicians and many other experts. 
There is no scientific, ethical or legal basis to ban snus, and we hope you will reconsider and change your position to support one of the three options listed above. In reality, you would be supporting better health and challenging the dominance of cigarette smoking, which is the most harmful and addictive form of tobacco and nicotine use.

High School Seniors’ Tobacco Use: Another Year in Decline

Smoking by teens has declined to record-low levels, according to the latest University of Michigan annual Monitoring the Future Study, which examines youth tobacco, alcohol and drug use in 2013 (data tables here).  The figure at left, which shows the percentage of high school seniors using alcohol, marijuana, cigarettes and smokeless tobacco in the past 30 days over the period 1975-2013, is highly informative. 

Cigarette use continued a long-term decline, reaching 16.3%, the lowest prevalence since the survey’s introduction in 1975.  Cigarette use was lower than marijuana use (22.7%) for the fifth consecutive year.  Smokeless tobacco use among boys was 14.6%, and among girls 1.4%. 

The CDC issued a press release in September describing a scary but unsubstantiated gateway scenario, crystallized by CDC Director Tom Frieden: “Many teens who start with e-cigarettes may be condemned to struggling with a lifelong addiction to nicotine and conventional cigarettes.”

Frieden’s speculation was based on data from the National Youth Tobacco Survey in 2012, indicating that 0.054% of high school students in the U.S. used an e-cigarette at least once in the 30 days prior to the survey and had not smoked or used any other tobacco product.  Of the nearly 15 million high school students in the U.S., that’s about 8,000.  Meanwhile, about 1.8 million students smoked. 

Smoking prevalence among high school seniors has declined every year since 2007, about the time that e-cigarettes were introduced in the U.S.  With numbers like this, it is unlikely that e-cigarette use has contributed to teen smoking.

NYU to E-Cigarette Users: Cigarettes Are Healthier



I have noted in the past how prestigious organizations sometimes spew misinformation about the risks of smokeless tobacco; I have been especially critical of individuals representing the Mayo Clinic (here), the MD Anderson Cancer Center (here) and the Karolinska Institute in Sweden (here). 

Now, e-cigarettes are being institutionally maligned, as in a particularly egregious December 11 attack-by-press-release at New York University (here).  Under the dramatic headline, “NYU Researchers are Lifting the Veil on the Hidden Health Impact of Electronic Cigarettes,” a professor was quoted as saying, “Due to the frequency of puffing, depth of inhalation, and length of vaping, e-cig users may actually absorb higher concentrations of nicotine and other toxins than conventional tobacco smokers.”

This allegation is demonstrably false.  Numerous published studies comparing e-cigarette vapor and cigarette smoke reveal that the latter contains much higher concentrations of nicotine and toxic agents (this is one of many examples).  I am not aware of any legitimate study suggesting that vapor is more toxic than cigarette smoke.

The NYU press release obtained wide dissemination in the world’s media (example here).

E-cigarettes are used by millions of individuals throughout the world, the vast majority of them former smokers.  The apparently authoritative press release falsely informed them that vaping is more dangerous than smoking.  Based on this misinformation, it is likely that some vapers will abandon e-cigarettes and start smoking, which will constitute a public health tragedy.

It is remarkable that NYU’s press release revealed that Drs. Lin and Deepak Saxena were planning to “collect saliva and oral mucosa from College of Dentistry patients who are e-cig users to determine the relative abundance of oral bacteria and changes in DNA in these patients in order to compare them with the effects found among conventional cigarette smokers.”  There is no record that either researcher conducted prior research on the use of e-cigarettes or any other tobacco product.

Because NYU orchestrated the global dissemination of this false claim of vaping danger, I asked school officials to issue a press release retracting the statement. They did not respond.
