Recommendations are made for improving fidelity reporting in tobacco treatment trials.
E-cigarettes versus nicotine replacement treatment as harm reduction interventions for smokers who find quitting difficult: Randomised controlled trial
Published: 30/06/2021, Addiction
Conclusions: In smokers unable to quit using conventional methods, e-cigarettes were more effective than nicotine replacement therapy in facilitating validated long-term smoking reduction and smoking cessation, when limited other support was provided. Findings: validated smoking reduction (including cessation) was achieved by 26.5% vs 6.0% of participants in the EC and NRT study arms, respectively, relative risk (RR)=4.4.
Regulatory approaches and implementation of minimally addictive combusted products
Published: 30/06/2021, Nicotine and Tobacco Research
Introduction: A joint meeting was held by the World Health Organization (WHO) and the Convention Secretariat of the WHO Framework Convention on Tobacco Control to examine the potential effects of a regulatory policy to reduce nicotine in cigarettes to minimally addictive levels. This paper reviews the feasibility of and approaches to implementing a nicotine product standard. For the countries that choose to implement it, such a policy could potentially dramatically reduce the burden of tobacco use.
Flavour chemicals, synthetic coolants and pulegone in popular mint-flavoured and menthol-flavoured e-cigarettes
Published: 30/06/2021, Tobacco Control
Conclusions: Switching from flavoured JUUL to Puff e-cigarettes may expose users to increased harm due to the higher levels of WS-23 and pulegone in Puff products. Cancer risk may be reduced in e-cigarettes by using pure menthol rather than mint oils to produce minty-flavoured e-cigarette products.

Review: This review aims to summarize the progress made in research on the effects of tobacco on the nervous system both of the perinatal period and adults and both in animals and humans in 2015-2020.
The current state of tobacco cessation treatment
Published: 01/07/2021, Cleveland Clinic Journal of Medicine
Review: Key points: i) An individualized treatment for tobacco cessation is necessary and should be based on severity of nicotine dependence, probability of developing withdrawal symptoms, comorbidities, local resources, and patient preferences. ii) Comprehensive smoking cessation treatment provides counseling, assesses the patient’s readiness to quit, offers treatment options, and arranges follow-up. iii) Evidence is lacking to support the use of smart phone “apps” for smoking cessation as monotherapy. iv) E-cigarettes are not used in tobacco cessation treatment as they can also cause nicotine addiction and other concerns.
Smoking from a Younger Age Is the Dominant Factor in the Incidence of Chronic Obstructive Pulmonary Disease: Case-Control Study
Published: 4/06/2021, International Journal of Environmental Research and Public Health
Conclusion: There are three factors of smoking behavior that influence COPD: smoking habit, initial smoking age and smoking duration. Of all factors, forming a smoking habit at the age of <15 years old has the biggest risk (OR = 12).
The Influence of Friends on Teen Vaping: A Mixed-Methods Approach
Published: 24/06/2021, International Journal of Environmental Research and Public Health
Conclusions: Among survey respondents, friends were the most common source of vapers' first ENDS product (60%). Most survey respondents tried their first ENDS product while "hanging out with friends" (54%). Among follow-up research participants, the theme of socializing was also prominent. ENDS advertising and marketing through social media had a strong association with friend networks; in fact, the odds of friends as source of the first vaping experience were 2 times higher for those who had seen ENDS ads on social media compared with other types of media. The influence of friends is particularly evident among non-Hispanic Whites, Hispanics/Latinos, those living in urban areas, those living in high-income households, those with higher self-esteem, and those who experiment with vaping. These findings support the premise that peer influence is a primary social influencer and reinforcer for vaping. Being included in a popular activity appears to be a strong driving force.
Targeted smoking cessation for dual users of combustible and electronic cigarettes: a randomised controlled trial
Published: 01/07/2021, Lancet Public Health
Background: Although many smokers use electronic cigarettes (e-cigarettes) to quit smoking, most continue to smoke while vaping. This dual use might delay cessation and increase toxicant exposure. We aimed to test the efficacy of a self-help intervention designed to help dual users to quit smoking. Interpretation: A targeted self-help intervention with high potential for dissemination could be efficacious in promoting smoking cessation among dual users of combustible cigarettes and e-cigarettes.
Thirdhand Smoke Knowledge, Attitudes, and Behavior: Development of Reliable and Valid Self-report Measures
Published: 24/06/2021, Nicotine and Tobacco Control
Conclusion: The proposed knowledge, attitude and behaviour scales about thirdhand smoke provide new opportunities for tobacco control advocates and scholars to identify gaps in knowledge, misperceptions, and obstacles to behavior change in order to guide the design of novel tobacco control policies and interventions.
Mechanisms of parent-child transmission of tobacco and alcohol use with polygenic risk scores: Evidence for a genetic nurture effect
Published: May, Developmental Psychology
Results: Parental smoking initiation polygenic risk-score (PRS) predicted offspring cigarettes per day at age 24 (and alcohol use at age 17 independent of shared genetics. There was also a suggestive independent association between the parent PRS and offspring smoking at age 17 (β = .096; 95% CI [.02, .17]). Mediation analyses provided some evidence for environmental effects of parental smoking, alcohol use, and family socioeconomic status. These findings, and more broadly the molecular genetic method used, have implications on the identification of environmental effects on developmental outcomes such as substance use.
The Role of Pharmacogenetics in Smoking
Published: 24/06/2021, Clinical Pharmacology and Therapeutics
Review: In this brief review we highlight the role of pharmacogenes in smoking behaviours such as smoking status, consumption, nicotine dependence, spontaneous quitting, and altered abstinence to pharmacotherapies; We provide examples from initial candidate gene associations and subsequent genome-wide association studies.
The association of in utero tobacco smoke exposure, quantified by serum cotinine, and Autism Spectrum Disorder
Published: 24/06/2021, Autism Research
Conclusion: In one of the few studies of Environmental Tobacco Smoke (ETS) and the first with measured cotinine, our results indicate no overall relationship between in utero exposure to tobacco smoke from maternal ETS exposure or active smoking, and development of Autism Spectrum Disorder.
Protecting vulnerable groups from tobacco-related harm during and following the COVID-19 pandemic
Published: 23/06/2021,Health Promotion and Chronic Disease Prevention Canada
In this commentary, we discuss how the pandemic has been acting to further increase the harm from tobacco endured by these groups by applying the syndemic framework. […] These include the worsening of psychological distress, a potential increase in smoking behaviour, greater exposure to second-hand smoke and less access to smoking cessation services. Then, we offer mitigation strategies to protect disadvantaged groups from tobacco-related harm during and following the COVID-19 pandemic. These strategies include affordable smoking cessation services, a proactive approach for smoking treatment using information technology, opportunistic screening and treatment of tobacco dependence among individuals presenting for COVID-19 vaccination, policy interventions for universal coverage of cessation pharmacotherapy, comprehensive smoke-free policies and regulation of tobacco retail density
Assessing the responses of smokers to requests to stop smoking on hospital grounds
Published: 23/06/2021, Health Promotion Journal Australia
Conclusions: Only four instances of aggression were experienced, representing 2% of all interactions. Each of these were limited to verbal aggression. By following de-escalation-based protocols, staff can approach smokers in a low-risk manner and support smoke-free policy implementation and compliance. SO WHAT?: These protocols could be implemented by other health services or organisations that are seeking to optimise the involvement of staff in supporting smoke-free policies.
Reinforcement enhancement by nicotine: A novel abuse-liability assessment of e-cigarettes in young adults
Published: 24/06/2021, Experimental and Clinical Psychopharmacology
Results: Although nicotine was associated with greater subjective evaluation of the enjoyment of the videogame, it was unrelated to the enjoyment of the e-cigarette device. No evidence was found that nicotine elevated either anhedonia or withdrawal symptoms in the timeframe of the study. The results provide initial evidence that nicotine enhancement, via electronic cigarettes, occurs in non-frequent users of nicotine products and may be a reason they can develop nicotine dependence in the absence of withdrawal and direct effects of nicotine.

E-cigarette manufacturers’ compliance with clinical trial reporting expectations: a case series of registered trials by Juul Labs
Published: 14/06/2021, Tobacco Control
Discussion: Our findings raise substantial concerns regarding these trials. Clinicians, public health professionals, and the public cannot make informed choices about the benefits or hazards of e-cigarettes if the results of clinical trials are not completely and transparently reported. Clarification and potential enforcement of reporting laws may be required.
Smokers’ awareness of filter ventilation, and how they believe it affects them: findings from the ITC Four Country Survey
Published: 15/06/2021, Tobacco Control
Interpretation: Awareness of filter ventilation is currently low, despite decades of public ‘education efforts around the misleading nature of ‘light’ and ‘mild” descriptors. Few smokers realise that their cigarettes almost certainly are vented. Smokers who believed their cigarettes have filter ventilation were more likely to believe they were both smoother and less harmful. Awareness of the technology appears to be insufficient to prevent smokers being deceived by it. Filter ventilation is inherently misleading to smokers and it is time to ban it.
Second-hand smoke surveillance and COVID-19: a missed opportunity
Published: 11/06/2021, Tobacco Control
Excerpt: Second-hand tobacco smoke (SHS) exposure is a known causal risk factor for CVD and chronic lung disease,5 and may also be a risk factor for COVID-19 severity. […] None of the researchers who responded to our queries had data to assess SHS exposure as a risk factor for COVID-19 severity or outcomes. […] In response to our queries, several authors acknowledged the missed opportunity to obtain data that might inform future public health interventions for COVID-19.
Intensified advertising of heated tobacco products in Japan: an apparent shift in marketing strategy
Excerpt: In 2019, 27% and 8% of men and women, respectively, were current smokers; among whom, 20% of both men and women used HTPs exclusively, and 7% and 5% of men and women, respectively, used both HTPs and conventional cigarettes.2 The sales share of HTPs in 2019 was 24% of tobacco products.3 To understand how the tobacco industry has increased market share of HTPs so shortly in Japan, we examined the recent trend of tobacco advertising in newspapers and magazines.

Conclusion: Most studies found that smoke-free legislation in hospitality venues is associated with a decrease in smoking behavior among young people. Their results indicate the need for comprehensive smoke-free legislation without exemptions.
Smoked cigarette butts: Unignorable source for environmental microplastic fibers
Published: 09/06/2021, The Science of the Total Enviornment
…Discarded cigarette butts may be carried into rivers and lakes, and finally into the ocean. The plastic fibers will continuously release microplastic fibers into the environment. About 300,000 tons of potential microplastic fibers may enter the aquatic environment from this source per annum. Additionally, toxic substances, such as nicotine, carcinogenic tar, and polycyclic aromatic hydrocarbons, have strong toxic effect, which will cause serious damage to aquatic organisms…
Clinical burden, risk factor impact and outcomes following myocardial infarction and stroke: A 25-year individual patient level linkage study
Published: 17/06/2021, Lancet – Regional Health
Interpretation: Looking as Scottish data, over the last 25 years, substantial reductions in myocardial infarction and ischemic stroke incidence are attributable to major shifts in risk factor levels. Changes in risk factors between 1990 and 2014 (Systolic blood pressure, smoking and cholesterol decreased, but body-mass index increased), accounted for a 74% (57-91%) reduction in myocardial infarction and 68% (55-83%) reduction in ischemic stroke. Following myocardial infarction, the risk of death decreased (30% to 20%), but non-fatal events increased (20% to 24%) whereas the risk of both death (47% to 34%) and non-fatal events (22% to 17%) decreased following stroke.
Efficacy of Combining Varenicline and Naltrexone for Smoking Cessation and Drinking Reduction: A Randomized Clinical Trial
Published: 16/06/2021, The American Journal of Psychiatry
Conclusions: These findings suggest that smoking cessation and drinking reduction can be concomitantly targeted with pharmacotherapy and that while varenicline alone may be sufficient as a smoking cessation aid in heavy-drinking smokers, the combination of varenicline and naltrexone may confer benefits with regard to drinking outcomes, particularly during the 12-week period of active medication treatment.
Understanding pathways to e-cigarette use across sexual identity: A multi-group structural equation model
Published: March/2021, Addictive Behaviours
Findings: These findings suggest that students who report sexual violence may experience suicidality and victimization may lead to smoking behaviors and e-cigarette use. Students’ mental health and substance use behaviors should continue to be targeted in schools, particularly among sexual minority youths.

Trends in e-cigarette brands, devices and the nicotine profile of products used by youth in England, Canada and the USA: 2017–2019
Published: 10/06/2021, Tobacco Control
Background: The e-cigarette market has rapidly evolved, with a shift towards higher nicotine concentration and salt-based products, such as JUUL; however, the implications for youth vaping remain unclear. Results In 2019, the use of pod- or cartridge-style e-cigarettes was greater in Canada and the USA than England, with Smok and JUUL the leading brands in all countries. In 2019, youth vapers in England were less likely to report using e-cigarettes with ≥2% nicotine (12.8%) compared with Canada (40.5%; adjusted OR (AOR)=4.96) and the USA (37.0%; AOR=3.99) and less likely to report using nicotine salt-based products (12.3%) compared with Canada (27.1%; AOR=2.77) and the USA (21.9%; AOR=2.00). In 2019, self-reported use of products with higher nicotine concentration was associated with significantly greater frequency of vaping, urges to vape and perceived vaping addiction (p<0.05 for all).
Underutilisation of no-tobacco-sale orders against retailers that repeatedly sell to minors, 2015–2019, USA

Conclusions The FDA’s failure to fully leverage its powers to address retailers’ underage sales of tobacco products has weakened efforts to curb the youth e-cigarette epidemic
Support for cigarette filter waste policies among US adults
Results: Regardless of smoking status, 71% did not know plastic was a cigarette filter component and 20% believed filters were biodegradable. Overall, 23% believed filters reduce health harms and 60% believed filters make it easier to smoke; 90% believed cigarette butts are harmful to the environment. Individuals believing cigarette butts harmed the environment were more likely to support a litter fee. Individuals believing that filters are not biodegradable had higher odds of supporting a litter fee. Respondents believing that filters do not make cigarettes less harmful were more likely to support a litter fee and filter ban. Belief that filters make it easier to smoke was associated with decreased support for a filter ban.
Hypothetical flavour ban and intention to vape among vape shop customers: the role of flavour preference and e-cigarette dependence
Results: Those who preferred flavours showed significantly lower intention to purchase e-liquids and to continue vaping , given a hypothetical flavour ban. Those who vaped for smoking cessation indicated greater intention to purchase e-liquid (β=0.10, p=0.016) and to continue vaping, given a hypothetical flavour ban. E-cigarette dependence significantly mediated these effects.
Smokers’ use of e-cigarettes in situations where smoking is not permitted in England: quarterly trends 2011-2020 and associations with sociodemographic and smoking characteristics
Published: 05/06/2021, Nicotine and Tobacco Research
Conclusions: In England, use of e-cigarettes in situations where smoking is not permitted is common among dual cigarette and e-cigarette users, has increased non-linearly since 2011, and is particularly prevalent among those who are younger, disadvantaged, more addicted, have recently failed to quit, and are not attempting to cut down.
E-cigarette promotion is pervasive in the digital world: The “shared environment” of today’s youth
Published: 09/06/2021, Nicotine and Tobacco Research
[Editorial] … The protections that were designed to shield youth from exposure to tobacco via media (e.g., movies) and advertising (e.g., television, radio) are now becoming obsolete and therefore ineffective because youth today view YouTube or other video platforms instead. These platforms do not allow paid advertisement of tobacco products, but product placement in viewed content—while difficult to tell whether paid, who is paid and who is paying—still results in considerable exposure…
Increasing cannabis use is associated with poorer cigarette smoking cessation outcomes: Findings from the ITC Four Country Smoking and Vaping Surveys, 2016-2018
Published: 10/06/2021, Nicotine and Tobacco Research
Conclusions: Smokers who increase their frequency of cannabis use have poorer smoking cessation outcomes compared to non-cannabis using smokers. It will be important to monitor the impact of cannabis legalization on patterns of cannabis use, and whether this influences cigarette smoking cessation rates.
Cigarette Smoking and Risk Perceptions During the COVID-19 Pandemic Reported by Recently Hospitalized Participants in a Smoking Cessation Trial

Electronic Cigarette Use Is Not Associated with COVID-19 Diagnosis
Published: June 2021, Journal of Primary Care and Community Health
Results: Patients who used only e-cigarettes were not more likely to have a COVID-19 diagnosis (OR 0.93 [0.69-1.25], P = .628), whereas those who used only cigarettes had a decreased risk (OR 0.43 [0.35-0.53], P < .001). The OR for dual users fell between these 2 values (OR 0.67 [0.49-0.92], P = .013). Although e-cigarettes have the well-documented potential for harm, they do not appear to increase susceptibility to SARS-CoV-2 infection. This result suggests the hypothesis that any beneficial effects of conventional cigarette smoking on susceptibility are not mediated by nicotine.
Tobacco use among substance use disorder (SUD) treatment staff is associated with tobacco-related services received by clients
Published: 01/06/2021, Journal of Substance Use Disorder
Conclusion: Higher rates of tobacco use among staff are associated with higher rates of client tobacco use and fewer clients receiving cessation counseling. Efforts to reduce tobacco use among SUD clients should be supported by efforts to reduce tobacco use among staff. SUD treatment programs, and agencies that fund and regulate those programs, should aim to reduce the use of tobacco products among staff.

Sensitivity analysis indicated that our results were stable and robust.
Differences in quit attempts, successful quits, methods, and motivations in a longitudinal cohort of adult tobacco users by sexual orientation
Published: 01/06/2021, Nicotine and Tobacco Research
Results: Quit rates were similar for heterosexual and SM adults. Over half attempted to quit at least once over 48 months, but few remained abstinent (SM: 16.9%; heterosexual: 12.1%). Most used nicotine replacement therapy (SM: 31.9%; heterosexual: 26.1%) or tobacco product substitution (SM: 27.7%; heterosexual: 21.2%). Few used quitlines (SM: 4.3%; heterosexual: 1.3%) or internet-based programs (SM: 6.4%; heterosexual: 1.3%). Quit motivations included health concerns, family, and physical fitness. Participants reporting a successful quit were more likely to report a household member quit smoking than 24-hour quit attempters. Among participants reporting a successful quit, more SM than heterosexual participants reported that a coworker quit smoking (55.6% vs 33.1%, p = .009).
Impact of an inner-city smoke-free zone on outdoor smoking patterns: a before-after study
Results: Before implementation of the smoke-free zone [Netherland, Rotterdam, Erasmus University
hospital campus], 4,098 people smoked in the area every weekday during working hours. After implementation, the daily number of smokers was 2,241, a 45% reduction (p=0.007). There was an increase of 432 smokers per day near and just outside the borders of the zone. At baseline, 31% of the smokers were categorised as employee, 22% as student and 3% as patient. Following implementation of the smoke-free zone, the largest decreases in smokers were observed among employees (–67%, p-value 0.004) and patients (–70%, p-value 0.049). Before and after implementation, 21 and 20 smokers were visibly addressed and asked to smoke elsewhere.
Predictors of Enrollment of Older Smokers in Six Smoking Cessation Trials in the Lung Cancer Screening Setting: The Smoking Cessation at Lung Examination (SCALE) Collaboration
Published: 02/06/2021, Nicotine and Tobacco Research
Conclusion: Enrolling smokers in cessation interventions in the LCS setting is a major priority that requires multiple enrollment and intervention modalities. Barriers to enrollment provide insights that can be addressed and applied to future cessation interventions to improve implementation in LCS and other clinical settings with older smokers.
Effect of a hypothetical modified risk tobacco product claim on heated tobacco product use intention and perceptions in young adults
Published: 31/05/2021, Tobacco Control
Discussion: The hypothetical MRTP claim may lower young adults’ HTP harm perceptions compared with cigarettes but may not change HTP use intention overall or differentially for cigarette smokers. The larger effect on HTP use intention among e-cigarette users than non-users raises the question of whether MRTP claims may promote HTP use or HTP and e-cigarette dual use among young e-cigarette users.
Promoting corporate image or preventing underage use? Analysis of the advertising strategy and expenditures of the JUUL parent education for youth vaping prevention campaign
Results: Advertisements aired nationally and in over half of all US-designated market areas (n=130) across media platforms including newspapers, magazines, radio, and online in mobile web and internet displays. In 2018, JUUL Labs spent $30 million, predominantly for print advertising. The ‘What Parents Need to Know about JUUL’ ads primarily advertised JUUL’s smoking reduction ‘mission’ and promoted the product. By 2019, advertising increased to $36.2 million. JUUL’s message strategy transitioned to ‘Cracking Down on Underage Sales in Retail Stores’ and featured adult smoker testimonies, linking JUUL to smoking cessation.

Smoking and COVID-19 Infection and Related Mortality: A Prospective Cohort Analysis of UK Biobank Data
Published: 25/05/2021, Clinical Epidemiology
Conclusion: The association between smoking and COVID-19 infection and subsequent death is modified by age. Smokers and previous smokers aged under 69 were at higher risk of COVID-19 infection, suggesting the risk is associated with increased exposure to SARS-COV-2 virus. Once infected, older smokers were twice as likely to die from COVID-19 than never smokers, possibly mediated by increased risk of chronic conditions/illnesses.
