RE: Does Snus use have a harm reduction effect in Sweden?

Eletter to Tobacco Control in response to an eletter published in the same journal about whether snus (Swedish moist oral snuff) was responsible for a decline in smoking prevalence among men in Sweden.

Assessment of Swedish snus for tobacco harm reduction: technical appendix

This technical appendix details the methods used in an assessment of the potential of snus for tobacco harm reduction using simulation modelling.

Should the health community promote smokeless tobacco (snus) as a harm reduction measure?

Background to the debate: The tobacco control community is divided on whether or not to inform the public that using oral, smokeless tobacco (Swedish snus) is less hazardous to health than smoking tobacco. Proponents of 'harm reduction' point to the Swedish experience. Snus seems to be widely used as an alternative to cigarettes in Sweden, say these proponents, contributing to the low overall prevalence of smoking and smoking-related disease. Harm reduction proponents thus argue that the health community should actively inform inveterate cigarette smokers of the benefits of switching to snus. However, critics of harm reduction say that snus has its own risks, that no form of tobacco should ever be promoted, and that Sweden’s experience is likely to be specific to that culture and not transferable to other settings. Critics also remain deeply suspicious that the tobacco industry will use snus marketing as a 'gateway' to promote cigarettes. In the interests of promoting debate, the authors (who are collaborators on a research project on the future of tobacco control) have agreed to outline the strongest arguments for and against promoting Swedish snus as a form of harm reduction.

Physical Activity and Snus: Is There a Link?

The study aimed at assessing the link between physical activity (PA), sports activity and snus use among young men in Switzerland. Data from the Cohort Study on Substance Use Risk Factors (C-SURF) were used to measure PA with the International Physical Activity Questionnaire and sports activity with a single item. Multivariate logistic regression analysis was conducted to measure the association between snus use, PA and sports activity. Similar models were run for smoking and snuff use. Snus use increased in a dose-response association with PA (high level: OR = 1.72; 95% CI 1.16-2.55) and with individuals exercising once a week or more often (OR = 1.65; 95% CI 1.26-2.16; p < 0.001) or almost every day (OR = 2.27; 95% CI 1.72-3.01; p < 0.001) in separate models. Entered simultaneously, only sports and exercise maintained a basically unchanged significant dose-response relationship, whereas PA became non-significant. A non-significant dose-response relation was found for cigarette smoking and snuff use, indicating that the association with sport is specific to snus and not to tobacco use in general or smokeless tobacco in particular. This study showed that the association between snus use and sports is not specific to Nordic countries.

The prospects for tobacco harm reduction

Tobacco harm reduction (THR) policies aim to reduce the prevalence of tobacco-related harm by encouraging smokers who are unable or unwilling to quit to adopt less harmful ways of obtaining nicotine, such as pharmaceutical nicotine and oral tobacco snuff. Proponents of THR argue that the effects of tobacco control policies have reduced smoking as much as they reasonably can and that we can best reduce tobacco-related harm by encouraging smokers to use these methods, which substantially reduce the health risks of smoking. Critics argue that THR policies will undermine the two traditional tobacco control goals of preventing the uptake of smoking by young people and encouraging smokers to quit. I assess the main arguments and evidence advanced for and against THR.

Determination of nicotine and nicotine metabolites in urine by hydrophilic interaction chromatography-tandem mass spectrometry: Potential use of smokeless tobacco products by ice hockey players.

Consumption of nicotine in the form of smokeless tobacco (snus, snuff, chewing tobacco) or nicotine-containing medication (gum, patch) may benefit sport practice. Indeed, use of snus seems to be a growing trend and investigating nicotine consumption amongst professional athletes is of major interest to sport authorities. Thus, a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the detection and quantification of nicotine and its principal metabolites cotinine, trans-3-hydroxycotinine, nicotine-N'-oxide and cotinine-N-oxide in urine was developed. Sample preparation was performed by liquid-liquid extraction followed by hydrophilic interaction chromatography-tandem mass spectrometry (HILIC-MS/MS) operated in electrospray positive ionization (ESI) mode with selective reaction monitoring (SRM) data acquisition. The method was validated and calibration curves were linear over the selected concentration ranges of 10-10,000 ng/mL for nicotine, cotinine, trans-3-hydroxycotinine and 10-5000 ng/mL for nicotine-N'-oxide and cotinine-N-oxide, with calculated coefficients of determination (R(2)) greater than 0.95. The total extraction efficiency (%) was concentration dependent and ranged between 70.4 and 100.4%. The lower limit of quantification (LLOQ) for all analytes was 10 ng/mL. Repeatability and intermediate precision were ?9.4 and ?9.9%, respectively. In order to measure the prevalence of nicotine exposure during the 2009 Ice Hockey World Championships, 72 samples were collected and analyzed after the minimum of 3 months storage period and complete removal of identification means as required by the 2009 International Standards for Laboratories (ISL). Nicotine and/or metabolites were detected in every urine sample, while concentration measurements indicated an exposure within the last 3 days for eight specimens out of ten. Concentrations of nicotine, cotinine, trans-3-hydroxycotinine, nicotine-N'-oxide and cotinine-N-oxide were found to range between 11 and 19,750, 13 and 10,475, 10 and 8217, 11 and 3396, and 13 and 1640 ng/mL, respectively. When proposing conservative concentration limits for nicotine consumption prior and/or during the games (50 ng/mL for nicotine, cotinine and trans-3-hydroxycotinine and 25 ng/mL for nicotine-N'-oxide and cotinine-N-oxide), about half of the hockey players were qualified as consumers. These findings significantly support the likelihood of extensive smokeless nicotine consumption. However, since such conclusions can only be hypothesized, the potential use of smokeless tobacco as a doping agent in ice hockey requires further investigation.

Prevalence and factors associated with use of smokeless tobacco in young Swiss men.

BACKGROUND: Smokeless tobacco is of increasing interest to public health researchers and policy makers. This study aims to measure prevalence of smokeless tobacco use (nasal dry snuff, snus and chewing tobacco) among young Swiss men, and to describe its correlates. METHODS: We invited 13 245 young men to participate in this survey on socio-economic and substance use data. Response rate was 45.2%. We included 5720 participants. Descriptive statistics and multivariable-adjusted logistic regression were performed. RESULTS: Mean age of participants was 19.5 years. Self-reported use once a month or more often was 8% for nasal dry snuff, 3% for snus and negligible for chewing tobacco. In multivariable-adjusted logistic regression, the odds for nasal dry snuff use increased in non daily smokers [odds ratio (OR) 2.41, 95% confidence interval (CI) 1.90-3.05], compared with non smokers, participants reporting risky weekly drinking volume (OR 3.93, 95% CI 1.86-8.32), compared with abstinents, and binge drinking once a month or more often (OR 7.41, 95% CI 4.11-13.38), compared with never binge drinking. Nasal dry snuff use was positively associated with higher BMI, average or above family income and German language, compared with French, and negatively associated with academic higher education, compared with non higher education, and occasional cannabis use, compared with no cannabis use. Correlates of snus were similar to those of nasal dry snuff. CONCLUSION: One in 12 young Swiss men use nasal dry snuff and 3% use snus. Consumption of smokeless tobacco is associated with a cluster of other risky behaviours, especially binge drinking.

Prévalence et facteurs associés à la consommation de tabac non fumé chez les jeunes hommes suisses

Introduction Le tabac non fumé (smokeless tobacco) comprend les formes de tabac qui ne sont pas consommées par combustion. Les deux principaux types de consommation sont le snus, par application sur la muqueuse orale, et le tabac à sniffer. Le premier se consomme surtout en Suède et les pays scandinaves ; la consommation du second a récemment fait son apparition en Suisse malgré son interdiction. Méthodes Nous avons utilisé la base de données de la Cohort on substance use risk factors (C-surf), une cohorte de jeunes hommes suisses se présentant à 3 centres de recrutement de l'Armée Suisse (Lausanne, Windisch et Mels). Un total de 13 245 jeunes hommes ont été invités à participer à cette enquête sur la consommation de substances. Le taux de réponses a été de 45.2%. Nous avons inclu 5720 participants pour cette analyse et utilisé une approche statistique par régression logistique pour identifier les déterminants de consommation de tabac non fumé. Résultats L'âge moyen des participants était de 19.5 ans. 8% des participants ont déclaré consommer régulièrement du tabac à sniffer et 3% consommer du snus au moins une fois par mois. La consommation de tabac à sniffer était associée à la consommation non quotidienne de cigarettes [odds ratio (OR) 2.41, 95% confidence interval (Cl) 1.90-3.05], ainsi qu'à celle d'alcool à risque (OR 3.93, 95% Cl 1.86-8.32) etépisodique (OR 7.41, 95% Cl 4.11-13.38). Un BMI élevé, un revenu familial au-dessus de la moyenne et un faible niveau de formation étaient également associés à la consommation de tabac à sniffer, alors que la consommation occasionnelle de cannabis l'était négativement. Les facteurs associés à la consommation de snus étaient similaires à ceux du tabac à sniffer. Conclusions Un jeune homme suisse sur 12 consomme du tabac à sniffer et 3% consomment du snus. La consommation de tabac non fumé est associée à d'autres comportements à risque, en particulier la consommation d'alcool à risque. Les résultats de la régression logistique multivariée montrent une association de la consommation de tabac non fumé à la consommation d'alcool à risque. Le rôle du tabac non fumé dans l'induction de la dépendance à la nicotine et dans l'initiation à d'autres comportements à risque, ainsi que ses effets sur la santé devront être analysés sur la base d'études longitudinales.

Consommation de tabac chez les jeunes hommes suisses: quelles influences de l'armée?

Le tabac à priser, appelé "snuff" ou encore "chnouff", est la plus ancienne forme de tabac connue en Europe (1). Il aurait été importé en Europe en 1493 par un moine Franciscain voyageant avec Christophe Colomb au retour des Caraïbes (2). Le tabac à priser consiste en une fine poudre de tabac communément brune actuellement vendue dans de petites boîtes de métal rondes. Dans la suite du manuscrit nous utiliserons le terme snuff pour désigner le tabac à priser. Il fait partie d'un groupe de produits appelé "tabac sans fumée" (en anglais "smokeless tobacco") comprenant également la snus (« moist snuff » en anglais, tabac non- fermenté destiné à une absorption par la muqueuse orale à ne pas confondre avec la snuff), et le tabac à mâcher (feuilles de tabac broyées ou compacts mastiquées puis recrachées). La plupart des articles scientifiques publiés sur le tabac sans fumée concernent la snus car elle est largement consommée dans les pays nordiques (en Suède et en Norvège plus particulièrement) et dans certains milieux sportifs.

"Com fumo ou sem fumo" : não é a questão! : dependência da nicotina, que tratamento?

A dependência da nicotina tem efeitos muito perigosos para a saúde, especialmente se a sua via de entrada é a respiratória feita através do fumo do tabaco. A cessação do acto de fumar e a desintoxicação da nicotina são objectivos da Organização Mundial da Saúde (OMS) e da União Europeia. Há produtos derivados do tabaco que são usados de forma diferente de fumar, como por exemplo, a inspiração, mascar, e sugar. Efeitos nocivos destas formas de consumo são também evidentes, contudo em menor extensão do que os causados pelo fumo. Os países Nórdicos têm uma longa e antiga tradição do uso de uma pasta húmida de tabaco que é colocada debaixo do lábio superior aqui designada por “snus”. Apenas 12% dos homens entre os 16 e os 84 anos de idade são fumadores diários na Suécia, enquanto que a percentagem de mulheres é 21%. Decorre um debate nos países Nórdicos, desde o início dos anos 90 do século passado, sobre os possíveis benefícios ganhos com a substituição do acto de fumar pelo “snussar”, isto é, o uso do “snus” e a introdução de derivados do tabaco sem fumo como uma via para a cessação de fumar. Deixar de fumar e a desabituação da nicotina requerem estratégias definidas por várias organizações e entidades oficiais. Acções recomendadas incluem a farmacoterapia e as intervenções no comportamento, contudo, os resultados atingidos estão longe dos desejados e novas abordagens estão a ser investigadas.

Tobaksbruk och tandvårdsvanor bland 15-70 åringar ur ett 20-års perspektiv (1983 - 2003)

Det tobakspreventiva arbetet är en av samhällets största utmaningar.Syftet med studien var att beskriva tobaksbruket och dess förändring över tid (1983-2003) iett slumpmässigt urval av individer 15-70 år i Jönköpings kommun. Den specifikamålsättningen var att analysera tobaksvanorna i relation till socioekonomiska förhållanden,personlighet, tandvård och tandvårdsvanor. Studien utgjordes av tre epidemiologiskatvärsnittsstudier utförda åren 1983, 1993 och 2003. En klinisk och röntgenologiskundersökning utfördes av mun och tänder. Individerna fick även besvara ett frågeformulär.Resultaten visade en statistiskt signifikant minskning av tobaksbruket från 31 %tobaksbrukare 1983 till 24 % såväl 1993 som 2003. Detta gällde samtliga åldersgrupper utomåldersgruppen 40-åringar. I första hand minskade andelen rökare. Samtidigt ökade snusarna isamtliga åldersgrupper 20-60 år innebärande ett i stort sett oförändrat tobaksbruk 1993 och2003. Det förelåg ingen statistisk signifikant skillnad vid de tre undersökningsåren mellantobaksbrukare och icke/brukare med avseende på inkomst-, utbildningsnivå, civilstånd, ochKASAM poäng. År 2003 förelåg en statistisk signifikant skillnad mellan brukare och ickebrukare med avseende på frekvens av tandvårdsbesök, där tobaksbrukarna i störreutsträckning än icke brukaren, inte besökte tandvården eller besökte tandvården oregelbundet.Icke brukarna borstade tänderna statistiskt signifikant oftare än tobaksbrukarna år 1993 ochicke brukarna använde tandstickor statistiskt signifikant oftare än tobaksbrukarna år 1983 och2003.

Swedish Match : En kvalitativ studie om butikskonceptet

Title: Swedish Match-En kvalitativ studie om butikskonceptet  Author: Adam Waernér/Erik Rehnberg  Supervisor: Jonas Jonasson  Key Words: Communication, Branding, Culture, PR, Advertisement  Purpose: The purpose of this research is to understand the background of the launch of Swedish Match´s stores. Because of the strict laws against marketing of tobacco products in Sweden, we believe that the stores are an interesting way of approaching a new branding and communication strategy in the tobacco industry.  Research questions: What´s the background to the launch of Swedish Match Stores? What´s the stores impact on Swedish Match image? How do Swedish Match Stores impact the cultural status of snus? In what ways do the cultural trends impact the snus market?  Theory: In this study we have applied theories concerning culture, communication, branding, PR and advertisement. Methodology: We have chosen to apply a qualitative method on this research. The method consists of three different methods: one focus group, one observation study which consists of two different observations both in the Gothenburg store and the store in Stockholm, the last method is an online interview with the public relations officer of Swedish Match in Sweden. Because of the chosen method´s we hope to bring three different perspectives to the  study: From the customers perspective, from our own perspective and finally from the company´s perspective.  Findings: Through this research we discovered that the stores do not only work as a communication strategy for Swedish Match. The store as a phenomenon also works in the aspect of branding, PR and also gives a higher cultural status to snus. Through our own observation and the focus group we came to the conclusion that the stores in terms of image of Swedish Match implements a cultural aspect of swedishness to the company, as well as a more modern and new take on snus. We also came to the conclusion that snus is a cultural phenomenon that is impacted of other contemporary trends, such as gastronomic trends and the increased popularity of small scale exclusivity.
