This study examined a supervised moderate-intensity aerobic exercise programme's effectiveness in regulating the Tobacco Withdrawal Symptoms (TWS) during temporary abstinence. This was a single group, pre and post-quasi intervention study. Thirty daily smokers participated in an 8-week supervised moderate-intensity aerobic exercise programme. We assessed the TWS, smoking urge, mood and stress-pleasure related hormonal variables after the aerobic exercise intervention. The measurements were conducted after overnight abstinence at baseline, post-intervention (at week-8) and post-detraining (at week-10). TWS components, smoking urge and mood were found to improve. For hormonal variables, cortisol and beta-endorphin except adrenaline showed insignificant changes at post-intervention and de-training. The findings suggest moderate-intensity exercise might help in reducing withdrawal symptoms and its adverse effects. Thus, exercise is an effective adjunct treatment in a smoking cessation programme.

Background: Almost 30% of Chilean women report cigarette smoking with important repercussions on their health.

Objective: Design and test a mobile phone intervention for smoking cessation in young women.

Study design: A mobile application (app) was created using the best available evidence and consumer input. Its effectiveness was assessed through a randomized clinical trial.

Study participants: Women 18 to 44 years old from middle-class neighborhoods in Santiago, Chile. Inclusion criteria were intention to quit cigarette smoking in the following month and having a smartphone cell phone. Women with positive screening for risky alcohol consumption were excluded.

Intervention: App with content to support cigarette smoking cessation over 6 months. The control arm included an app that delivered general messages to promote permanence in the study. Telephone follow-up was performed at 6 weeks, and at 3 and 6 months after randomization.

Main outcome measure: No smoking in the past 7 days at 6 weeks from enrolment. Intention-to-treat analysis was carried out using SPSS 17.0 with a significance level set at .05.

Results: 309 women entered the study. Mean number of cigarettes smoked in a day was 8.8. 58.6% of the participants (n = 181) completed the follow-up for the primary outcome. With intention-to-treat analysis, 9.7% of participants in the intervention group reported not having smoked any cigarettes in the last 7 days vs 3.2% in the control group (RR 2.98 CI 95% 1.11-8.0, P = .022). Additionally, 12.3% vs 1.9% of the participants in the intervention group and control group reported continuous abstinence at 6 weeks, respectively (RR 6.29 95% CI 1.9-20.8, P < .001). Continuous abstinence was also significant at 6 months (P-value of .036).

Conclusions: The "Appagalo" app is an effective tool to support smoking cessation in young women. It is a simple mHealth alternative for smoking cessation that can contribute to improving women's health in the Americas and worldwide.

E-cigarettes (electronic cigarettes) have been the most used tobacco product among US youth since 2014, reaching a plateau during the COVID-19 pandemic. Youth e-cigarette use is associated with negative health consequences such as impaired cognitive functioning. For many, the COVID-19 pandemic altered social interactions, harm perceptions, and product availability. This changed the frequency and locations in which youth use e-cigarettes. To better understand youth e-cigarette use, we need more information on factors that can alter e-cigarette use, specifically, how the pandemic changed e-cigarette use among youth. In 2020-2021, we conducted online, individual interviews with 19 youth (aged 13-17) e-cigarette users living in the US to explore how COVID-19 impacted their e-cigarette use. Youth described a progression of e-cigarette use from initial experimentation, regular social use, and ultimately to nicotine addiction demonstrated by individual use in isolation. Many youth initiated e-cigarette use due to influences by friends or family members. Youth discussed progression to social use, with social interactions as an important reason for use and an avenue for expanding one's knowledge of e-cigarettes. After a period of time, youth began to recognize that the social interactions mattered less, suggesting to them that they had become addicted. This realization became more apparent during COVID-19, which changed how youth used e-cigarettes, especially around where use was occurring, health concerns, and use behavior and frequency. In our interviews, youth trajectory began with an initiation with family and friends, progressed to social use, and eventually developed to addiction, at which point social use was no longer the primary motivation for e-cigarette use. Understanding the trajectory of e-cigarette use will allow for effective interventions that reduce harm to youth from e-cigarette use.

Introduction: Smoking remains a major health risk factor and China is the world's largest consumer of tobacco. Smoke-free policies in public places are a powerful weapon in tobacco control. Therefore, the aim of this study was to assess the association between smoke-free policies in public places and smoking cessation among smokers in China from 2012 to 2020.

Methods: In this study, we assessed the impact of smoke-free public places policies on smoking cessation situation among smokers aged 16 years and older. We do this by conducting a difference-in-differences analysis using data from the China Family Panel Study (CFPS) 2012-2020.

Findings: By 2020, about 60.2% of the cities were covered by partial smoke-free policies and about 38.5% by comprehensive smoke-free policies. Based on the results of the study, we found that the medium-term effect model (Model 2, 2012:2016; Model 3, 2012:2018) of the impact of partial smoke-free policies on smoking cessation was not statistically significant using 2012 as the study baseline; the short-term effect model (Model 1; 2012:2014; P< .01) and the long-term effect model (Model 4; 2012:2020; P< .05) were statistically significant; the effect of a comprehensive smoke-free policy on smoking cessation (Model 5; 2012:2020; P<.05) was statistically significant.

Conclusion: China's existing comprehensive smoke-free policies have had a modest impact on smoking cessation among the smoking population, and a strong, comprehensive national smoke-free law is urgently needed to achieve greater public health outcomes.

Implications: Smoke-free policies are an important intervention to influence smoking behavior. This study demonstrates that comprehensive smoke-free policies in public places in China can effectively influence smoking behavior and show long-term trends in smoke-free behavior, while also reflecting the need to promote comprehensive smoke-free policies. This study provides a basis for the implementation of comprehensive smokefree policies into law and also provides a basis for policy makers.

Introduction: Biochemical verification of smoking status prior to recruitment into smoking cessation trials is widely used to confirm smoking status, most commonly using exhaled carbon monoxide (CO). There is variation in the level of CO used as a biochemical inclusion criterion, and thus the possibility for people reporting to be current smokers to be incorrectly excluded from trials.

Methods: As part of the Cessation of Smoking Trial in the Emergency Department, people attending the Emergency Department (ED) who reported being current daily smokers underwent CO testing to confirm eligibility. Elective semi-structured interviews were undertaken with the researchers who recruited participants. As part of the interviews, researchers were asked their views and experiences with CO testing.

Results: Of the 1320 participants who reported being current daily smokers and underwent CO testing, 300 (22.7%) blew a CO reading of 7 ppm or less and were excluded from taking part. Possible explanations offered by researchers for participants blowing low CO readings were (1) long wait times in the ED, therefore a long period having elapsed since people had last smoked and (2) patients having reduced smoking for the period before the ED attendance due to ill health.

Conclusions: Biochemical verification has the potential to improve internal validity of smoking cessation for inclusion in trials, but at the cost of reduced generalisability through exclusion of participants who would receive the intervention if it were implemented in practice. We would recommend researchers carefully consider whether it is appropriate and necessary to include biochemical verification as an inclusion criterion.

We aimed to explore the behavioural protective mechanisms against cannabis use among adolescents living in South African illicit cannabis-growing communities, based on the Self Determination Theory (SDT). Exploratory qualitative design techniques were followed in conducting the study. The snowball sampling technique was used to recruit thirty (30) non-cannabis smoking adolescents from 2 purposively selected communities and grouped into 4 focus groups and interviewed. A semi-structured focus group interview guide was used to moderate the discussions. Data were analysed inductively, using the ATLAS. ti software. Nine behavioural coping mechanisms, grouped under intrinsic and extrinsic protective behavioural mechanisms, protected participants from using cannabis. Intrinsically, participants' determination not to engage in bad behaviours, focus on their academic work during their free periods, their non-financial dependence on cannabis-using peers, self-preservation to ensure good marriages, and religious beliefs on substance abuse motivated them to not use cannabis. On the other hand, the concept of Ukuphoxa (preservation of family dignity), fear of arrest, fear of being tagged a social deviant, and the fear of contracting illnesses such as lung cancer served as protective behavioural mechanisms against cannabis use. Health promotion and education programmes for adolescents on non-cannabis use in communities where illicit cannabis abounds must identify and draw on contextual intrinsic and extrinsic motivations that ensure non-cannabis use.

Background: With the emergence of the WHO Framework Convention on Tobacco Control, globally the use of tobacco has decreased notably, although, it still requires efforts at individual, organizational, community level to decrease the rate further. Dental professionals are at an excellent position to provide tobacco cessation counselling and interventions, however, it is not practiced much due to lack of training and lack of knowledge. Therefore, this systematic review was conducted to assess the global status of knowledge, attitude and practice on tobacco cessation interventions among dental professionals.

Materials and method: A systematic search of 6 databases with no language restriction since 2000 was undertaken. Studies were included if they assessed knowledge, attitude and practice on tobacco cessation interventions among dental professionals using a validated or prevalidated tool. The data obtained for assessment of knowledge, attitude, practice, curriculum and barriers were represented through heatmaps. Quality assessment of the studies was done using Newcastle Ottawa scale.

Results: Fifty six studies were included in this systematic review. Majority of the studies were found to be of moderate quality. Knowledge regarding the tobacco cessation interventions was more theoretical than practical. All the studies showed a favorable attitude among dental professionals towards tobacco cessation intervention.

Conclusion: The included studies lack homogeneity in assessing knowledge, attitude and practice on tobacco cessation interventions. The development and validation of a standardized questionnaire to assess knowledge, attitude and practice on tobacco cessation interventions could be a potentially effective way to uniformly gather data on the subject.
