Further research is needed to determine the most effective models of NHS treatment for smoking cessation and the efficacy of those models with subgroups. Factors such as gender, age, socio-economic status and ethnicity appear to influence outcomes, but a current lack of diversity-specific analysis of results makes it impossible to ascertain the differential impact of intervention types on particular subpopulations.

Over the past decade, the strategy of 'denormalising' tobacco use has become one of the cornerstones of the global tobacco control movement. Although tobacco denormalisation policies primarily affect people on the lowest rungs of the social ladder, few qualitative studies have explicitly set out to explore how smokers have experienced and responded to these legislative and social changes in attitudes towards tobacco use. Drawing on a qualitative study of interviews with 25 current and ex-smokers living in Vancouver, Canada, this paper examines the ways they interpret and respond to the new socio-political environment in which they must manage the increasingly problematised practice of tobacco smoking. Overall, while not opposed to smoking restrictions per se, study participants felt that recent legislation, particularly efforts to prohibit smoking in a variety of outdoor settings, was overly restrictive and that all public space had increasingly been 'claimed' by non-smokers. Also apparent from participants' accounts was the high degree of stigma attached to smoking. However, although the 'denormalisation' environment had encouraged several participants to quit smoking, the majority continued to smoke, raising ethical and practical questions about the value of denormalisation strategies as a way of reducing smokingrelated mortality and morbidity.

Abstract:Aims: To examine existing evidence on the effectiveness of interventions that are designed to prevent the illegal sale of tobacco to young people. The review considers specific sub-questions related to the factors that might influence effectiveness, any differential effects for different sub-populations of youth, and barriers and facilitators to implementation. Methods: A review of studies on the impact of interventions on young people under the age of 18 was conducted. It included interventions that were designed to prevent the illegal sale of tobacco to children and young people.

Objectives:To analyze existing evidence on the impact of two types of location restrictions on smoking: workplace bans and bans in hospitality settings, and to assess the extent to which they differentially affect subpopulations.Methods: A review of international studies on location restrictions on smoking published between 1990-2007.Results: Although workplace smoking bans reduce exposure to second-hand smoke (SHS) at work, their effects on overall cigarette consumption and smoking prevalence may be uneven across the population. Bans in hospitality settings reduce SHS exposure among workers, but have potentially uneven effects based on the interactions between gender, socio-economic status (SES) and ethnicity. The unintended consequences of smoking bans are also more likely to be experienced by low SES groups.Conclusions: Although location restrictions on smoking reduce SHS exposure and may serve to positively impact smoking behaviours, there is preliminary evidence that they may have a reduced impact on subpopulations such as low-income groups, although further research is needed.

Background: While comprehensive tobacco policies have reduced the prevalence of smoking in Canada, some groups remain vulnerable to tobacco use and display high rates of smoking. This article reviews three types of tobacco policies -tax and price, smoking location restrictions and sales restrictions -and examines the consequences for Aboriginal people, youth and low-income people. Methods:A better practices review model was used to assess the strength of studies published between 1990 and 2004 that examined the effects of these tobacco policies on the three vulnerable populations of interest. A total of 72 studies were assessed and 42 judged medium or high strength. A gender-based and diversity analysis was applied to assess the differential impacts on females and males and/or diverse characteristics within these populations. Intended and unintended consequences were examined.Findings: Few studies assessed the potential or differential effects of tobacco policies on the three selected populations. In these, it was difficult to disentangle the effects of each policy in a comprehensive tobacco control environment, and there is need for improved indicators and greater attention to sex and gender analysis. Conclusions:Research is required to measure the intended and unintended impacts of tobacco policies on populations vulnerable to tobacco use. There are problems in assessing these studies that could be resolved with more precise indicator development. An equity-based framework for assessing the effects of tobacco policies is needed that is conceptually linked to health determinants and inequities. The article concludes with a set of recommendations for research, evaluation, policy and ethics arising from this review.

This study investigated the connections between stressors, substance use, and experience of violence among women (N = 125) who accessed help from domestic violence shelters in British Columbia, Canada between October 2001 and June 2003. Changes in substance use and stressors following a shelter stay were explored, using both qualitative and quantitative methods. Women generally decreased their use of alcohol and stimulants, and this change was found to be integrally connected to social and structural supports made available to them. Future research that augments current stress models of addiction by considering social and structural factors that come into play in women's substance use and domestic violence is suggested. The study's limitations are noted.

General practitioners are often exhorted to routinely counsel patients who smoke about quitting in light of current evidence-based medicine (EBM) guidelines suggesting that such brief interventions provide an easy and effective way of increasing quit rates. Drawing on semi-structured interviews conducted with 25 smokers and 10 general practitioners (GPs) in British Columbia, Canada, this article explores smokers' and GPs' perspectives on smoking cessation interventions in primary care settings. Study findings indicate that both patients and GPs believe smoking is best broached when it is patient-initiated or raised in the context of smokingrelated health issues, and there was a broader consensus that the role of doctors is to provide education and information rather than coercing smokers to quit. However, smokers wanted further recognition of the difficulties of quitting smoking and many questioned the competence of GPs to deal with addiction-related issues. Similar barriers to smoking cessation were raised by smokers and GPs -primarily inadequate time and resources. Based on these findings, we argue that the assumption that primary care consultations provide an important venue for encouraging smokers to quit deserves reconsideration based on the complexity of this issue, the circumstances in which most GPs practice, and the danger of alienating smokers. Questions are raised about whether current EBM guidelines are an adequate tool for guiding individual clinical interactions between GPs and smokers.
