Abstract
BACKGROUND Measuring self-reported experience of health and functioning is important for understanding the changes in the health status of individuals switching from cigarettes to less harmful tobacco and/or nicotine products (TNP) or reduced-risk products (RRP) and for supporting tobacco harm reduction strategies. METHODS This paper presents insights from three research activities from the preparatory phase of the development of a new self-report health and functioning measure. A scoping literature review was conducted to identify the positive and negative impact of TNP use on health and functioning. Focus groups (n = 29) on risk perception and individual interviews (n = 40) on perceived dependence in people who use TNPs were reanalyzed in the context of health and functioning, and expert opinion was gathered from five key opinion leaders and five technical consultants. RESULTS Triangulating the findings of the review of 97 articles, qualitative input from people who use TNPs, and expert feedback helped generate a preliminary conceptual framework including health and functioning and conceptually-related domains impacted by TNP use. Domains related to the future health and functioning measurement model include physical health signs and symptoms, general physical appearance, functioning (physical, sexual, cognitive, emotional, and social), and general health perceptions. CONCLUSIONS This preliminary conceptual framework can inform future research on development and validation of new measures for assessment of overall health and functioning impact of TNPs from the consumers' perspective.

Abstract
BACKGROUND Alternative tobacco and nicotine products such as electronic cigarettes (EC), smokeless tobacco, and nicotine replacement therapy (NRT) are currently being assessed as options in tobacco harm reduction due to their potential role in smoking reduction and smoking cessation. OBJECTIVE To provide the current evidence on the effectiveness and safety of various alternative tobacco and nicotine products for smoking reduction and cessation. METHODS A systematic review using databases from MEDLINE (PubMed), EMBASE, and The Cochrane Library was conducted up to December 2020 to identify eligible experimental and observational studies assessing the use of alternative tobacco and nicotine products on smoking reduction and smoking cessation and the safety of these products. The Cochrane Risk of Bias 2 (RoB 2) and ROBINS-I tools were used to assess the risk of bias of the included studies. Results were described through a narrative synthesis of the evidence. RESULTS From 1955 retrieved references, 44 studies (31 randomized controlled trials/RCTs and 13 prospective cohort studies) met the inclusion criteria and were included in the review. Twenty-nine studies were assessing EC, one study evaluated heat-not-burn (HNB) product, five studies were focused on snus, and nine studies assessed NRT in the form of nicotine patch, gum, etc. The overall results suggested that alternative tobacco and nicotine products in the form of EC, snus, and NRT can moderately reduce daily cigarette consumption and has potential to assist smoking cessation attempts, with fewer adverse events. CONCLUSION The findings suggested that alternative tobacco and nicotine products have a potential role in assisting smoking reduction and cessation, highlighting their role in the tobacco harm reduction approach. Further studies should focus on investigating long-term outcomes, safety, and effectiveness of alternative tobacco and nicotine products to better inform smoking reduction/cessation policy.

Addiction 2017; 112:340-348. [PMID: 27741374 PMCID: PMC5248595 DOI: 10.1111/add.13638] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2015] [Revised: 03/07/2016] [Accepted: 10/05/2016] [Indexed: 01/11/2023]
Abstract
AIMS To examine how the relative size of six groups of male ever snus users (current and former users of snus who were current, former or never cigarette smokers) varied over time in Norway, and how these groups differ with regard to important measures of tobacco behaviour. DESIGN Repeated cross-sectional nationally representative surveys of tobacco use. The association between survey year and the six categories of ever snus use was examined using cross-tabulation and multinomial logistic regression. Differences in tobacco behaviour across snus use categories were examined using logistic and ordinary least squares (OLS) regression. SETTING Norway, 2003-15. PARTICIPANTS A total of 2067 males aged 15-79 years. MEASUREMENTS The categories of ever snus use represented all six combinations of cigarette smoking (current, former or never) among current and former users of snus. The variables measuring tobacco behaviour were: order of product uptake (snus or cigarettes first), mean cigarette consumption, reduction from daily to occasional smoking, intention to quit cigarettes, future smoking identity and use of snus in latest quit attempt. FINDINGS During the period 2003-15, the relative share of current snus users who had never smoked, and current snus users who were former smokers, increased. The share of dual users, and smokers who were former snus users, decreased. Among men who reported life-time experience with both products, a large majority had initiated their tobacco use with cigarettes. The average number of cigarettes smoked weekly was lower among dual users compared with current smokers who were former snus users or had never used snus. CONCLUSIONS During the period 2003-15 in Norway, which has a mature snus market, even though smoking has declined and the relative size of the category of never-smokers among male users of snus has increased, the majority of snus users are still former or current smokers.

Abstract
BACKGROUND Promoting and supporting smoking reduction in smokers with no immediate intention of stopping smoking is controversial given existing fears that this will deter cessation and that reduction itself may not improve health outcomes. DISCUSSION Evidence shows that smokers who reduce the number of daily cigarettes smoked are more likely to attempt and actually achieve smoking cessation. Further, clinical trials have shown that nicotine replacement therapy benefits both reduction and cessation. Worldwide data suggests that 'non-medical' nicotine is more attractive to people who smoke, with electronic cigarettes now being widely used. Nevertheless, only one small trial has examined the use of electronic cigarettes to promote reduction, with direct evidence remaining inconclusive. It has been suggested that long-term reduced smoking may directly benefit health, although the benefits are small compared with cessation. SUMMARY The combined data imply that smoking reduction is a promising intervention, particularly when supported by clean nicotine; however, the benefits are only observed when it leads to permanent cessation.

Abstract
OBJECTIVE Effective strategies are needed to encourage smoking cessation for smokers without an intention to quit. We systematically reviewed the literature to investigate whether smoking reduction therapy can increase the long-term cessation rates of smokers without an intention to quit. METHODS PubMed, Embase, and CENTRAL (Cochrane Central Register of Controlled Trials) were searched for randomized controlled trials (RCTs) on the effect of smoking reduction therapy on long-term smoking cessation in smokers without an intention to quit. The primary outcome was the cessation rate at the longest follow-up period. A random effects model was used to calculate pooled relative risks (RRs) and 95% confidence intervals (CIs). RESULTS Fourteen trials with a total of 7981 smokers were included. The pooled analysis suggested that reduction support plus medication significantly increased the long-term cessation of smokers without an intention to quit compared to reduction support plus placebo (RR, 1.97; 95% CI, 1.44-2.7; I(2), 52%) or no intervention (RR, 1.93; 95% CI, 1.41-2.64; I(2), 46%). In a subgroup of smokers who received varenicline or nicotine replacement therapy (NRT), the differences were also statistically significant. This suggests the safety of using NRT. The percentage of smokers with serious adverse events who discontinued because of these events in the non-NRT group was slightly significantly different than in the control group. Insufficient evidence is available to test the efficacy of reduction behavioural support in promoting long-term cessation among this population. CONCLUSIONS The present meta-analysis indicated the efficacy of NRT- and varenicline-assisted reduction to achieve complete cessation among smokers without an intention to quit. Further evidence is needed to assess the efficacy and safety of reduction behavioural support and bupropion.

Abstract
The study examined caregivers' interest in using potentially reduced exposure tobacco products for smoking cessation, reduction, and to help them not smoke in places such as around their child, as all three methods would potentially lead to reduced secondhand smoke exposure for their children. A sample of 136 caregivers completed carbon monoxide testing to assess smoking status and a brief survey. Few caregivers had ever used potentially reduced exposure tobacco products (<1%), but a majority were interested in trying them as means of smoking reduction (54%), to quit/stay quit from smoking (51%), and to help them not smoke around their child or in the home (55%). Caregivers less motivated to quit smoking and with no home smoking ban were more interested in using potentially reduced exposure tobacco products to help them quit/stay quit from smoking (p < .05).

Abstract
BACKGROUND In Norway, low-nitrosamine smokeless tobacco (snus) is allowed to compete with cigarettes for market share. We aimed to study how the availability of snus influenced overall tobacco consumption, smoking initiation and smoking cessation. We discuss whether the Norwegian experience with snus can have any transfer value for e-cigarettes. METHODS We analysed consumption data from registered and unregistered supply sources of tobacco. We calculated quit-smoking ratios across snus use status in nine datasets comprising a total of 19,269 ever-smokers. Trends in snus use and smoking were derived from time-series of annual; cross-sectional; nationally representative surveys for the period 1985-2013. RESULTS The market share for snus increased from 4% in 1985 to 28% in 2012, but overall tobacco consumption decreased by 20.3% over this same period. Snus was the most common method for smoking cessation. Compared with smokers with no experience of using snus, the quit ratio for smoking was significantly higher for daily snus users in seven of the nine datasets analysed. Among young male adults, the prevalence of smoking (daily + occasional) was reduced from 50% in 1985 to 21% in 2013. Over the same period, use of snus increased from 9% to 33%. This negative correlation (r = -0.900, p < 0.001) was also observed among young females (r = -0.811, p < 0.001), but the trend shift in tobacco preferences occurred some years later. CONCLUSIONS The experience with snus in Norway might indicate what will happen when alternative nicotine products--are allowed to compete with cigarettes in the nicotine market.

Abstract
OBJECTIVES To explore how advertising affects demand for cigarettes and potential substitutes, including snus, dissolvable tobacco, and medicinal nicotine. METHODS A Web-based experiment randomized 1062 smokers to see advertisements for alternative nicotine products or soft drinks, then complete a series of purchase tasks, which were used to estimate demand elasticity, peak consumption, and cross-price elasticity (CPE) for tobacco products. RESULTS Lower demand elasticity and greater peak consumption were seen for cigarettes compared to all alternative products (p < .05). CPE did not differ across the alternative products (p ≤ .03). Seeing relevant advertisements was not significantly related to demand. CONCLUSIONS These findings suggest significantly lower demand for alternative nicotine sources among smokers than previously revealed.

Abstract
INTRODUCTION Low-nitrosamine smokeless tobacco (SLT) may have efficacy for smoking reduction and cessation, but its public health impact depends on how smokers use it. METHODS This pilot study explored brief, instructional low-nitrosamine SLT use among smokers unmotivated to quit. Participants (N = 57) were randomized to either a free 2-week supply of Camel Snus group or a no-supply group. Of those randomized to use Camel Snus, half were told to use it to cope with smoking restrictions (Snus to Cope), and the remaining half were advised to use it to reduce smoking (Snus to Reduce). Participants were assessed before, during, and immediately after the intervention. RESULTS Many Snus to Cope and Snus to Reduce participants reported daily use of Camel Snus, although the amount of use was low. Snus to Cope (18.4%) and Snus to Reduce (37.6%) participants reported a decline in number of cigarettes used per day, which was not reported by the control participants (p < .001). Intention to quit smoking and intention to quit all tobacco use (ps < .001) increased to a greater extent among Snus to Cope and Snus to Reduce participants than among control participants. CONCLUSIONS This study replicates previous work that shows that low-nitrosamine SLT use can lead to reduced smoking and increased intention to quit, and it adds direct evidence to suggest that the function of low-nitrosamine SLT use-either to cope with smoking restrictions or to reduce smoking-can have a differential impact on smoking behavior. Overall, the results highlight the importance of messaging and, more specifically, marketing of low-nitrosamine SLT to smokers.

Abstract
Smokers of any age can reap substantial health benefits by quitting. In fact, no other single public health effort is likely to achieve a benefit comparable to large-scale smoking cessation. Surveys document that most smokers would like to quit, and many have made repeated efforts to do so. However, conventional smoking cessation approaches require nicotine addicted smokers to abstain from tobacco and nicotine entirely. Many smokers are unable – or at least unwilling – to achieve this goal, and so they continue smoking in the face of impending adverse health consequences. In effect, the status quo in smoking cessation presents smokers with just two unpleasant alternatives: quit or suffer the harmful effects of continuing smoking. But, there is a third choice for smokers: tobacco harm reduction. It involves the use of alternative sources of nicotine, including modern smokeless tobacco products like snus and the electronic cigarette (E-cig), or even pharmaceutical nicotine products, as a replacement for smoking. E-cigs might be the most promising product for tobacco harm reduction to date, because, besides delivering nicotine vapour without the combustion products that are responsible for nearly all of smoking’s damaging effect, they also replace some of the rituals associated with smoking behaviour. Thus it is likely that smokers who switch to E-cigs will achieve large health gains. The focus of this article is on the health effects of using an E-cig, with consideration given to the acceptability, safety and effectiveness of this product as a long-term substitute for smoking.

Abstract
Selected toxicant concentrations and other chemical measures have been determined for 43 U.S. smokeless tobacco products sold in 2006 and 2007. Products evaluated included moist snuff, dry snuff, loose leaf, plug, dissolvable and snus tobacco brands. Reference products available for scientific research purposes and eleven Swedish products were also evaluated and compared to the commercial products studied. Chemical endpoints determined included benzo[a]pyrene (B[a]P), N'-nitrosonornicotine (NNN), N'-nitrosoanatabine (NAT), N'-nitrosoanabasine (NAB), 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), N-Nitrosodimethylamine (NDMA), nitrite, cadmium, lead, arsenic, nickel, chromium, chloride, water, pH and nicotine. Different toxicant profiles were observed for the products studied, with snus tobacco brands generally containing relatively low concentrations of B[a]P and tobacco specific nitrosamines (TSNAs) compared to other moist snuffs. Smokeless tobacco reference product toxicant profiles were similar to corresponding commercial products, with the exception of the TSNA content of the dry snuff reference material. TSNA concentrations observed for all commercial products were lower than historically reported values, likely reflecting changes in product shelf life, tobacco curing practices and, possibly, product blend formulations during the last 20-30 years. The survey results summarized provide a temporal point of comparison with future data anticipated from FDA "harmful and potentially harmful constituents in tobacco products" reporting.

INTRODUCTION We examine the prevalence of dual use of snus and cigarettes among Norwegian men by categorizing dual use into four categories according to the frequency of use of each product, considering the order of uptake of both products, and examining reasons for additional snus use. We compare dual users and exclusive cigarette smokers with respect to their smoking intensity, plans for quitting smoking, and future smoking identity. METHODS We used a data pool of six cross-sectional, national representative surveys conducted annually in the period 2005-2010 containing a total of 3,524 males aged 16-74. RESULTS 6.8% of men had some kind of current concomitant use of snus and cigarettes--but only 1% reported a daily consumption of both products. The most typical pattern of dual use was a combination where daily use of one product was paired with occasional use of the other. Dual users consumed significantly fewer cigarettes per week (56.6; n = 226; SD, 53.82) than smokers who had either quit snus (79.6; n = 108; SD, 61.47) or single smokers with no history of snus use (80.2; n = 621; SD, 55.86). Only 24% with a history of dual use reported snus to be their first tobacco product, but the proportion who had initiated tobacco use with snus increased significantly with younger age. Among dual users with daily intake of snus, a majority of 53.6% reported that the purpose of their snus use was to quit smoking. A higher proportion of dual users (74.4%; 95% CI, 68.8-80.0; n = 235) than exclusive smokers (61.3%; 95% CI, 57.6-65.0; n = 658) reported that they most definitely or probably would be totally smoke-free 5 years into the future. CONCLUSIONS In the mature snus market of Norway, the magnitude of dual use of cigarettes and snus is relatively small. Dual users consume fewer cigarettes, and a higher proportion portray themselves as smoke-free in the future than do exclusive cigarette smokers.

Abstract
Background This study aimed to explore issues that might impact on the acceptability and feasibility of offering smokers nicotine containing products either to quit nicotine use altogether by using as a short term means of quitting cigarettes or as a longer term substitute. Method Two small pilot studies, one in the UK (n = 34) involving face to face contact and direct provision of the product, the other in Australia (n = 31) conducted remotely with products sent in the mail. Results Nicotine lozenges were the most popular products, but significant minorities liked a smokeless product more. Use stimulated interest in quitting, and although many failed to use all the products provided, most were interested in future use, more often to help quit than as a planned long-term substitute. Conclusions These studies indicate an untapped interest in the use of substitutes to reduce the harmfulness of smoking. Studies of this sort do not inhibit interest in quitting nicotine altogether, and may facilitate it. The greater the range of products on offer, the more smokers are likely to try a product to quit.

Rodu B. The scientific foundation for tobacco harm reduction, 2006-2011. Harm Reduct J 2011; 8:19. [PMID: 21801389 PMCID: PMC3161854 DOI: 10.1186/1477-7517-8-19] [Citation(s) in RCA: 44] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2011] [Accepted: 07/29/2011] [Indexed: 02/07/2023] Open
Abstract
Over the past five years there has been exponential expansion of interest in tobacco harm reduction (THR), with a concomitant increase in the number of published studies. The purpose of this manuscript is to review and analyze influential contributions to the scientific and medical literature relating to THR, and to discuss issues that continue to stimulate debate. Numerous epidemiologic studies and subsequent meta-analyses confirm that smokeless tobacco (ST) use is associated with minimal risks for cancer and for myocardial infarction; a small increased risk for stroke cannot be excluded. Studies from Sweden document that ST use is not associated with benign gastrointestinal disorders and chronic inflammatory diseases. Although any form of nicotine should be avoided during pregnancy, the highest risks for the developing baby are associated with smoking. It is documented that ST use has been a key factor in the declining rates of smoking and of smoking-related diseases in Sweden and Norway. For other countries, the potential population health benefits of ST are far greater than the potential risks. In follow-up studies, dual users of cigarettes and ST are less likely than exclusive smokers to achieve complete tobacco abstinence, but they are also less likely to be smoking. The health risks from dual use are probably lower than those from exclusive smoking. E-cigarette users are not exposed to the many toxicants, carcinogens and abundant free radicals formed when tobacco is burned. Although laboratory studies have detected trace concentrations of some contaminants, it is a small problem amenable to improvements in quality control and manufacturing that are likely with FDA regulation as tobacco products. There is limited evidence from clinical trials that e-cigarettes deliver only small doses of nicotine compared with conventional cigarettes. However, e-cigarette use emulates successfully the cigarette handling rituals and cues of cigarette smoking, which produces suppression of craving and withdrawal that is not entirely attributable to nicotine delivery. THR has been described as having "the potential to lead to one of the greatest public health breakthroughs in human history by fundamentally changing the forecast of a billion cigarette-caused deaths this century."

[PMID: 21219609 PMCID: PMC3032705 DOI: 10.1186/1477-7517-8-1] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2010] [Accepted: 01/10/2011] [Indexed: 01/18/2023] Open
Abstract
BACKGROUND It has been suggested that cigarette smokers will switch to alternative oral nicotine delivery products to reduce their health risks if informed of the relative risk difference. However, it is important to assess how smokers are likely to use cigarette alternatives before making predictions about their potential to promote individual or population harm reduction. OBJECTIVES This study examines smokers' interest in using a smokeless tobacco or a nicotine replacement product as a substitute for their cigarettes. METHODS The study included 67 adult cigarette smokers, not currently interested in quitting, who were given an opportunity to sample four alternative oral nicotine products: 1) Camel Snus, 2) Marlboro Snus, 3) Stonewall dissolvable tobacco tablets, and 4) Commit nicotine lozenges. At visit 1, subjects were presented information about the relative benefits/risks of oral nicotine delivery compared to cigarettes. At visit 2, subjects were given a supply of each of the four products to sample at home for a week. At visit 3, subjects received a one-week supply of their preferred product to see if using such products reduced or eliminated cigarette use. RESULTS After multiple product sampling, participants preferred the Commit lozenges over the three smokeless tobacco products (p = 0.011). Following the one week single-product trial experience, GEE models controlling for gender, age, level of education, baseline cigarettes use, and alternative product chosen, indicated a significant decline in cigarettes smoked per day across one week of single-product sampling (p < 0.01, from 11.8 to 8.7 cigarettes per day), but no change in alternative product use (approximately 4.5 units per day). Biomarkers of exposure showed no change in cotinine, but a 19% reduction in exhaled CO (p < 0.001). CONCLUSIONS Findings from this study show that smokers, who are currently unwilling to make a quit attempt, may be willing to use alternative products in the short term as a temporary substitute for smoking. However, this use is more likely to be for partial substitution (i.e. they will continue to smoke, albeit at a lower rate) rather than complete substitution. Of the various substitutes offered, smokers were more willing to use a nicotine replacement product over a tobacco-based product.
