Impact of alcohol and drug use on smoking and cessation in socioeconomically disadvantaged young adults

Smoking cessation among tuberculosis patients during the coronavirus disease-2019 pandemic

Smoking has been recognized as a significant risk factor for COVID-19 and mortality. The World Health Organization (WHO) has recommended smoking cessation to reduce the impact of COVID-19. This study aimed to evaluate the smoking cessation rate of patients starting tuberculosis (TB) treatment at six months using motivational interviewing based on the WHO "five steps to quit" model. In addition, we assessed the knowledge about smoking and the barriers to smoking cessation. We conducted a retrospective cohort study. Outpatients aged >18 years, smokers, and those who are starting TB treatment in two outpatient TB clinics were invited to participate. Patients received information about the importance of smoking cessation, especially in TB patients, and standardized advice based on guidelines. This information was repeated during phone calls during the second and fourth months of treatment. During the study period, 111 patients were included. The primary outcome was the smoking cessation rate at the end of the sixth month of treatment, which was 26.8% (19/71). The barriers to smoking cessation described by the patients were anxiety/depression (47.4%), seeing someone smoking (38.5%), drug use (19.2%), and alcohol abuse (2.6%). The assessment of knowledge about smoking showed that patients had some information gaps. In conclusion, TB smokers who tried to quit smoking during the COVID-19 pandemic faced many challenges. Despite this, we demonstrated a reasonable smoking cessation rate with a nurse-conducted motivational interview.

Smoking, vaping and drinking: A qualitative analysis of Aotearoa New Zealand young adults who tried e-cigarettes to stop smoking tobacco

BACKGROUND AND AIM

Social practices such as smoking-drinking co-use often go 'hand-in-hand', linked by the coordination of materials, skills and meanings. However, the experience of using e-cigarettes while drinking among people who smoke (and drink) remains underexplored. We used social practice theory to show how smoking, vaping and drinking intersect and to explain how vaping created two new social practices among people who tried e-cigarettes to stop smoking: 'vaping-drinking' co-use and 'smoking-vaping-drinking' poly-use.

METHODS

We conducted five in-depth interviews over 18-24 weeks during 2018-19, with each of nine Aotearoa New Zealand young adults aged 20-29 years. Participants smoked daily, did not regularly use e-cigarettes at entry and wished to try vaping to stop smoking. We analysed participants' reports of smoking or vaping while drinking using thematic analysis.

RESULTS

Individual participants reported both co-use and poly-use occasions throughout the study. Vaping-drinking co-use arose from practice 'replacement' processes, where vaping fully substituted smoking. Smoking-vaping-drinking poly-use arose from 'adjacency' processes where vaping complemented smoking. Participants used both processes flexibly over time, which required new skills in material, temporal, pleasure and social coordination to try to recreate valued meanings of comfort, security and communality associated with well-established smoking-drinking practices. Unsuccessful coordination attempts maintained smoking-drinking co-use.

CONCLUSION

Among Aotearoa New Zealand young adult smokers who want to use vaping to stop smoking, drinking occasions may help to maintain existing smoking-drinking practices and facilitate the development of vaping-drinking co-use and smoking-vaping-drinking poly-use practices, potentially prolonging individuals' exposure to smoking.

[What is the contribution of smoking to the increased risk of suicide in young smokers? A systematic review]

OBJECTIVES

The correlation between smoking and suicide is well documented in the general population: there is an increased risk of suicide among tobacco smokers. However, the association between smoking and suicidal behaviors (ideations, plans, attempts) in youth is poorly elucidated. This is a systematic review of the literature examined data on the relationship between active and passive smoking and suicidal ideation (SI), suicide planning (SP), and suicide attempts (SA) among youth in the general population.

METHOD

Medline searches were performed for the period 1980-2020. Cross-sectional, case-control, prospective population-based studies of young people (age less than 18 years) were included in this review; studies of specific populations (patients with an identified pathology of any kind) were excluded.

RESULTS

This review included 43 studies: 23 studies on the association between active smoking and SI, SI and/or PS, TS; three studies on the association between passive smoking and suicidal behavior, three studies on the association between smoking and suicidal behavior in young people in psychiatric hospital settings, and five studies comparing the suicidal behavior of girls and boys. Analysis of the data collected lead to the conclusion that active or passive smoking is associated with suicidal behavior in young people. Smoking appears to contribute to psychopathological disorders, including depression, the use of other psychoactive substances, or psychosocial suffering which are often associated with an increased risk of suicide in young people. The correlations between smoking and the presence of mental disorders have been highlighted; tobacco use may contribute to the development of depression, anxiety and stress. Further studies are needed to verify the existence of a causal link between smoking and suicide.

CONCLUSION

Smoking is associated with the risk of suicidal behavior in young people; it should be included among the criteria for assessing suicidal risk in youth. Smoking cessation, which improves psychological well-being, should be further integrated into the prevention of suicidal behavior.

Tailored text message and web intervention for smoking cessation in U.S. socioeconomically-disadvantaged young adults: A randomized controlled trial

The prevalence of cigarette smoking in young adults is higher among those with socioeconomic disadvantage than those without. Low treatment-seeking among young adult smokers is compounded by few efficacious smoking cessation interventions for this group, particularly socioeconomically-disadvantaged young adults (SDYA) who smoke cigarettes. The goal of this study was to test a tailored smoking-cessation intervention for SDYA. 343 SDYA aged 18-30 living in the U.S. (85% female) who smoke cigarettes with access to a smartphone and interest in quitting smoking in the next six months were recruited online in Spring 2020 and randomized to referral to online quit resources (usual care control; n = 171) or a 12-week tailored text message smoking-cessation program with a companion web-based intervention (n = 172). Intent to treat analyses examined associations between study condition, self-reported 30-day point prevalence abstinence (PPA), and confidence to quit smoking at 12 weeks, controlling for potential confounders. Intervention group participants had greater self-reported 30-day PPA at 12-weeks than controls (adjusted relative risk 3.93, 95% CI 2.14-7.24). Among those who continued smoking, the intervention increased confidence to quit (0.81 points, 95% confidence interval 0.08-1.53). Weekly engagement in the intervention predicted greater cessation. A tailored text message intervention for SDYA increased smoking abstinence and confidence to quit at the end-of-treatment. Findings may have been influenced by recruitment at the start of the COVID pandemic but suggest that text messaging is an acceptable and efficacious cessation strategy for SDYA smokers. Future studies should examine the impact on longer-term smoking-cessation and importance of intervention tailoring for SDYA.

Efficacy of smartphone applications for smoking cessation in heavy-drinking adults: Secondary analysis of the iCanQuit randomized trial

INTRODUCTION

Efficacious smoking cessation treatments are needed for heavy-drinking adults who often have difficulty quitting smoking. In a secondary analysis of a parent randomized controlled trial, we explored the efficacy of an Acceptance and Commitment Therapy (ACT)-based smartphone application (iCanQuit) versus a US Clinical Practice Guidelines (USCPG)-based smartphone application (QuitGuide) for smoking cessation among heavy-drinking participants (4 + drinks/day for women; 5 + drinks/day for men).

METHODS

Participants were randomized to receive iCanQuit (n = 188) or QuitGuide (n = 160) for 12-months. Smoking cessation outcomes were measured at 3, 6 and 12-months. The primary outcome was self-reported complete-case 30-day point prevalence abstinence (PPA) at 12-months. Secondary outcomes were 7-day PPA at all timepoints; prolonged abstinence; and cessation of all nicotine-containing products at 12-months. Multiple imputation and missing-as-smoking analyses were also conducted. Exploratory outcomes were cessation of both smoking and heavy drinking and change in alcohol use (drinks/day) at 12-months. Treatment engagement and satisfaction and change in ACT-based processes were compared between arms.

RESULTS

Retention rate was 85% at 12-months and did not differ by arm. At 12-months, iCanQuit participants had nearly double the odds of smoking cessation compared to QuitGuide (complete-case 30-day PPA = 24% vs. 15%; OR = 1.87 95% CI: 1.03, 3.42). Findings were similar for the multiple imputation and missing-as-smoking outcomes at 12-months. Combined cessation of smoking and heavy drinking, and alcohol use at 12-months did not differ by arm. iCanQuit was significantly more engaging and satisfying than QuitGuide. Increased acceptance of thoughts about smoking mediated the effect of treatment on cessation of heavy drinking at 12-months.

CONCLUSIONS

The iCanQuit smartphone application was more efficacious and engaging for smoking cessation among heavy-drinking adults than a USCPG-based smartphone application.

Comparative efficacy and safety of pharmacological interventions for smoking cessation in healthy adults: A network meta-analysis

Smoking is the leading cause of morbidity and mortality in different non-communicable diseases, and cessation leads to immense health benefits. The present network meta-analysis has been conducted to evaluate and compare the effects of available pharmacological interventions for smoking cessation in adults. A standard meta-analysis protocol was developed and after performing a comprehensive literature search on MEDLINE/PubMed, Cochrane databases, and International Clinical Trials Registry Platform, reviewers extracted data from 97 randomized controlled trials. PRISMA guidelines were followed in data extraction, analysis and reporting of findings. Random effects Bayesian network meta-analysis was done to pool the effects across the interventions. Network graph was built, and for closed triangles in the network graph, node splitting analysis was performed. The primary outcome measure was self-reported biochemically verified smoking abstinence at six months. The number of participants achieving continuous abstinence was reported. Data for the number of participants reporting at least one adverse event was also extracted, if available. Combination of nicotine receptor agonist and nicotine replacement therapy had a significant odd of 4.4 (95%CrI:2.2-8.7), bupropion and nicotine receptor agonist 4.0 (95%CrI:2.1-7.7), bupropion and nicotine replacement therapy 3.8 (95%CrI:2.3-6.2), combination nicotine replacement therapy has an odd of 2.6 (95%CrI:1.8-3.8), and nicotine receptor agonist had a significant odd of 2.7 (95%CrI:2.3-3.2) when compared to placebo (moderate quality of evidence) for continuous abstinence at 6 months. When compared with behavioural therapy, the odds ratio of interventions was not statistically significant. Combination of nicotine receptor agonist and nicotine replacement therapy has the highest probability of being the best treatment for abstinence from smoking.
