RESUMO
This paper aims to explore the possibility of employing large language models (LLMs) - a type of artificial intelligence (AI) - in clinical pharmacology, with a focus on its possible misuse in bioweapon development. Additionally, ethical considerations, legislation and potential risk reduction measures are analysed. The existing literature is reviewed to investigate the potential misuse of AI and LLMs in bioweapon creation. The search includes articles from PubMed, Scopus and Web of Science Core Collection that were identified using a specific protocol. To explore the regulatory landscape, the OECD.ai platform was used. The review highlights the dual-use vulnerability of AI and LLMs, with a focus on bioweapon development. Subsequently, a case study is used to illustrate the potential of AI manipulation resulting in harmful substance synthesis. Existing regulations inadequately address the ethical concerns tied to AI and LLMs. Mitigation measures are proposed, including technical solutions (explainable AI), establishing ethical guidelines through collaborative efforts, and implementing policy changes to create a comprehensive regulatory framework. The integration of AI and LLMs into clinical pharmacology presents invaluable opportunities, while also introducing significant ethical and safety considerations. Addressing the dual-use nature of AI requires robust regulations, as well as adopting a strategic approach grounded in technical solutions and ethical values following the principles of transparency, accountability and safety. Additionally, AI's potential role in developing countermeasures against novel hazardous substances is underscored. By adopting a proactive approach, the potential benefits of AI and LLMs can be fully harnessed while minimizing the associated risks.

OBJECTIVE: Reducing harm from combustible cigarette use among women of reproductive age (WRA) is critical given their potential vulnerability to multigenerational adverse impacts of cigarette smoking. Although electronic nicotine delivery systems (ENDS) are not approved smoking cessation aids in the US, many WRA who smoke report using ENDS to help quit smoking. Associations between ENDS use patterns and smoking-cessation efforts among US WRA remain unclear. METHODS: Using the Population Assessment of Tobacco and Health (PATH) Study, we examined whether baseline (Wave 3 or 4) ENDS use frequency predicted (a) making a cigarette quit attempt (QA) and (b) successful quitting by follow-up (Wave 4 or 5, respectively) among WRA (N = 2834; 72.1% non-Hispanic White). RESULTS: Daily ENDS use predicted greater adjusted odds of making a QA than non-daily (AOR = 1.63, 95% CI = 1.03, 2.59) and no ENDS use (AOR = 1.97, 95% CI = 1.23, 3.14), and greater odds of successful smoking cessation than non-daily use (AOR = 2.37, 95% CI = 1.31, 4.26). Daily ENDS use did not significantly improve odds of successful smoking cessation compared to no ENDS use (AOR = 1.62, 95% CI = 0.97, 2.69). Non-daily ENDS use did not significantly improve odds of making a QA (AOR = 1.21, 95% CI = 0.94, 1.56) and hindered successful smoking cessation compared to no ENDS use (AOR = 0.68, 95% CI = 0.48, 0.98). CONCLUSIONS: These findings suggest that benefits of ENDS for smoking cessation in WRA may be greatest among those who use ENDS daily. WRA who choose to use ENDS to help quit would be well-informed by evidence that non-daily ENDS use may impede smoking cessation.
RESUMO
OBJECTIVE: To examine associations of concern, worry, and stress about discrimination, shootings/violence, and police brutality and exclusive and dual tobacco and cannabis use among young adults. METHODS: A prospective, racially/ethnically diverse cohort of young adults (n = 1960) living in Los Angeles, California completed a baseline survey in 2020 (age range: 19-23) and a follow-up survey in 2021. Exploratory factor analysis (EFA) was employed on nine variables assessing levels of concern, worry, and stress about societal discrimination, societal shootings/violence, and community police brutality at baseline. Past 30-day tobacco and cannabis use at follow-up was categorized as current exclusive tobacco, exclusive cannabis, and dual tobacco and cannabis (vs never/former) use based on eleven use variables. Multinomial logistic regressions estimated adjusted associations between each factor score (translated to standard deviation units) with exclusive and dual tobacco and cannabis use. RESULTS: The EFA produced four factor scores representing concern/worry/stress (i.e., distress) about community police brutality (F1), distress about societal shootings/violence (F2), and distress about societal discrimination (F3), as well as generalized stress about police brutality, shootings/violence, and discrimination (F4). F1, F2, and F3 were associated with subsequent exclusive current cannabis use, with F1 having the strongest association (OR: 1.35, 95% CI: 1.18-1.55), while only F1 (OR: 1.51, 95% CI: 1.27-1.78) was associated with dual tobacco and cannabis use. None of the factors were associated with exclusive tobacco use. CONCLUSIONS: Young adult concern, worry, and/or stress about social problems may increase risk of cannabis use with or without concurrent tobacco use 6-12 months later.

SIGNIFICANCE: A growing number of adults use more than one tobacco product, with dual use of cigarettes and e-cigarettes being the most common combination. Monitoring sex disparities in tobacco use is a public health priority. However, little is known regarding whether dual users differ by sex. METHODS: Data came from Waves 4-6 (12/2016-11/2021) of the Population Assessment of Tobacco and Health Study, a US nationally-representative longitudinal survey. This analysis included current adult dual users of cigarettes and e-cigarettes. We used weighted generalized estimating equations to assess the association between sex and (1) making a cigarette quit attempt (n = 1882 observations from n = 1526 individuals) and (2) smoking cessation (n = 2081 observations from n = 1688 individuals) across two wave pairs, adjusting for age, education, ethnicity, time-to-first cigarette after waking, and e-cigarette use frequency. RESULTS: Among US dual users, 14.1% (95% Confidence Intervals [Cl] = 11.9-16.4) of females and 23.4% (20.0-26.9) of males were young adults (aged 18-24), 11.7% (9.2-14.2) of females and 14.4% (11.6-17.2) of males had Assuntos

RESUMO
Background: E-cigarette use is on the rise and many who use e-cigarettes also smoke combustible cigarettes. Dual use (i.e., use of both electronic and combustible cigarettes) is associated with greater rates of cannabis use and cannabis use among individuals who engage in dual use is related to more severe ecigarette-related problems. Yet, no known studies have tested whether cannabis use is related to more severe e-cigarette problems via negative affect and the expectation that e-cigarettes can help manage negative affect. Objectives: The current study tested this hypothesis among 400 adults who endorsed dual use, 33% of whom endorsed current (past three month) cannabis use. Results: Results indicated that participants with cannabis use reported more anxiety, depression, e-cigarette problems, and the following e-cigarette use expectancies: negative consequences, negative reinforcement, and weight concerns. Multiple mediator models found that the relation between cannabis use status and e-cigarette problem severity was mediated by anxiety (but not depression) and by negative reinforcement and weight concerns (but not negative consequences) expectancies. Serial mediator models indicated that the relation between cannabis use and e-cigarette problems occurred via the serial effects of anxiety and negative reinforcement (but not weight concerns) expectancies. Conclusions: These results highlight several clinical correlates of cannabis use among adults who smoke combustible and e-cigarettes, and suggest that anxiety and the expectation that e-cigarettes may help manage such negative emotions play important roles in e-cigarette-related problems among these individuals.

BACKGROUND: While smartphone apps for smoking cessation have shown promise for combustible cigarette smoking cessation, their efficacy in helping dual users of combustible and electronic cigarettes (e-cigarettes) to quit cigarettes remains unknown. This study utilized data from a randomized trial to determine if an Acceptance and Commitment Therapy (ACT)-based app (iCanQuit) was more efficacious than a US Clinical Practice Guidelines-based app (QuitGuide) for combustible cigarette smoking cessation among 575 dual users. METHODS: The primary cessation outcome was self-reported, complete-case 30-day abstinence from combustible cigarettes at 12 months. Logistic regression assessed the interaction between dual use and treatment arm on the primary outcome in the full trial sample (N = 2,415). We then compared the primary outcome between arms among dual users (iCanQuit: n = 297; QuitGuide: n = 178). Mediation analyses were conducted to explore mechanisms of action of the intervention: acceptance of cues to smoke and app engagement. Results: There was an interaction between dual use of combustible and e-cigarettes and treatment arm on the primary outcome (p = 0.001). Among dual users, 12-month abstinence from cigarettes did not differ between arms (23% for iCanQuit vs. 27% for QuitGuide, p = 0.40). Mediation analysis revealed a significant positive indirect effect of the iCanQuit app on 12-month abstinence from cigarettes through acceptance of emotions that cue smoking (p = 0.004). CONCLUSIONS: Findings from this study of dual users of combustible and e-cigarettes showed no evidence of a difference in quit rates between arms. Acceptance of emotions that cue smoking is a potential mechanism contributing to cigarette smoking abstinence among dual users.

Objective: Tobacco use is elevated among individuals with eating disorders (EDs). Yet, further research is needed to understand associations between cigarette and e-cigarette use patterns and ED symptomatology. To gain a more comprehensive understanding of tobacco use and EDs, this study characterized ED symptomatology and tobacco use patterns, including exclusive cigarette use, e-cigarette use, dual use, and nonuse. Method: Young adults aged 18-24 years who self-reported exclusive cigarette, e-cigarette, dual, or nonuse (N = 2500) were recruited via Lucid, an online survey management company. Participants completed questionnaires assessing body dissatisfaction, global ED psychopathology, binge eating and self-induced vomiting frequency, and demographics. ED diagnostic groups included: anorexia nervosa (AN), bulimia spectrum eating disorders (BSED), atypical AN, and night eating syndrome (NES). Results: Multinomial logistic models revealed those with AN were more likely to be dual users, those with atypical AN were more likely to be exclusive e-cigarette users, and participants with a BSED or NES were more likely to be exclusive e-cigarette or dual users, compared to those without an ED. General linear models suggested body dissatisfaction and global ED psychopathology were higher among exclusive e-cigarette and dual users, while binge eating and self-induced vomiting frequencies were greater among all tobacco use groups compared to nonusers. Discussion: Our findings suggest young adults with ED symptomatology were more likely to be users of e-cigarettes exclusively or dual users. It will be necessary to examine how these associations manifest using longitudinal and clinical populations in future research.

The consumption of tobacco continues to be the greatest preventable health risk in Germany. Every year, more than 127,000 people die prematurely as a result of using tobacco - one in five new cases of cancer is a consequence of smoking. Germany's current tobacco control policy, consisting of advertising bans, the promotion of smoke-free environments, and an abstinence-only paradigm, are only able to initiate slow change. Other countries have shown how the number of smokers can be reduced and deaths prevented by integrating harm reduction as a complementary measure and providing a much more active support for people who want to quit. This article first presents the current situation and current measures in Germany. Then recommendations for changes to the current tobacco control policy in Germany are derived from a look at the United Kingdom, which is considered a pioneer throughout Europe with its tobacco control policy, as well as a summary of the current state of research.

Dual use of electronic cigarettes and conventional cigarettes may be a transitional state towards cigarette smoking cessation. However, maintaining dual use may increase tobacco-related consequences as smoking behavior persists. The aim of our study was to describe characteristics of dual users and explore factors associated with their one-month abstinence in comparison to exclusive smokers in French smoking cessation services (SCS). We retrospectively studied 5116 smokers registered in a national SCS registry between 2015 and 2018 and who attended at least two visits. We matched the retained exclusive smokers and dual users by age, sex, professional status and education level. We compared baseline information and validated smoking abstinence at one-month follow-up between the two groups. Predictors of abstinence were assessed using a multivariate model. Retained exclusive smokers and dual users had similar cessation rates (37%). Compared to exclusive smokers, dual users presented more comorbidities and a higher level of nicotine dependence. Factors positively associated with cessation in dual users were: being employed or retired, declaring three or more previous quit attempts, presenting with low nicotine dependence and high motivation to quit and benefiting from at least four follow-up consultations. Our results suggest that dual users seeking help to quit in SCS seem to benefit from support as much as exclusive smokers to reach abstinence, despite a higher level of nicotine dependence and comorbidities. Further research, especially qualitative, is needed on this specific group of smokers to provide tailored interventions to quit.

To reduce biological risks, raising awareness for dual-use issues already at the level of university education is essential. Currently, most life sciences education programs do not incorporate biosecurity and dual-use in their regular curricula. Consequently, the responsibility rests with individual lecturers and depends on their initiative to incorporate dual-use topics into teaching activities. Students interested in biosecurity and dual-use topics often only have the option to educate themselves in external or online courses. Here, we provide practical guidance on how to initiate and integrate a dual-use education program within the curriculum and provide a selection of existing teaching materials. In addition, we suggest key learning objectives to guide the planning of dual-use courses. Different course formats like lectures, seminars, or stand-alone events are discussed regarding their advantages, disadvantages, and suitability for conveying the learning objectives to different educational stages and audiences. As a minimum, we recommend the incorporation of dual-use issues into at least one mandatory course. Ideally, students should additionally participate in in-depth seminars, which can be voluntary and offered in cooperation with external organisations.

BACKGROUND: Smoking cessation is the most important intervention in chronic obstructive pulmonary disease (COPD), asthma, and asthma-COPD overlap (ACO); however, high rates of current cigarette smoking are observed in adults with these respiratory diseases. Meanwhile, rapidly increasing use of heated tobacco products (HTPs) is observed in Japan; however, the status of HTPs use has not been fully understood in adults with COPD, asthma, and ACO. This study aimed to reveal the association between COPD, asthma, and ACO and HTPs use in adults. METHODS: Data on Japanese individuals ≥ 40 years old obtained from the Japan Society and New Tobacco Internet Survey were analyzed. The prevalence of HTPs use in adults with COPD, asthma, and ACO, among individuals categorized into three groups according to cigarette smoking (never, former, and current), was calculated and the relationship between each disease and HTPs use were evaluated. The clinical diagnosis of these diseases was based on the self-reported diagnosis, as obtained from questionnaires. RESULTS: A total of 19,308 individuals were included. The proportions of never, past, and current cigarettes smokers were 10,900 (56.5%), 4,903 (25.4%), and 3,505 (18.2%), respectively, and that of HTPs use was 1,813 (9.4%). In current cigarettes smokers, the adjusted odds ratios (ORs) of HTPs use was 2.88 (95% CI [confidence interval], 1.86-4.47), 1.23 (95% CI, 0.99-1.52), and 5.81 (95% CI, 3.12-10.82) in adults with COPD, asthma, and ACO compared to those without these respiratory diseases, respectively. Meanwhile, in past cigarettes smokers, the adjusted ORs of HTPs use was 0.51 (95% CI, 0.24-1.08), 0.69 (95% CI, 0.53-0.88), and 0.25 (95% CI, 0.06-1.07) in adults with COPD, asthma, and ACO, respectively. CONCLUSIONS: HTPs use is more prevalent among current cigarettes smokers with COPD, asthma, and ACO compared to those without these respiratory diseases. Complete cessation of smoking both cigarettes and HTPs is the only way to achieve complete smoking cessation, therefore, adults with COPD, asthma, and ACO need to make greater efforts to quit smoking.

Latinx individuals who smoke represent a tobacco health disparities group. Yet, limited research has focused on examining dual combustible and electronic cigarette use among Latinx populations. Importantly, Latinx persons who smoke also evince elevated rates of pain problems and symptoms and prior research has consistently linked pain problems and severity to smoking prevalence, maintenance, and behavior. Accordingly, the current study sought to build from the limited work that exists among dual combustible cigarette and electronic cigarette Latinx users comparing levels of pain severity and interference. The current sample consists of 196 adult Latinx daily cigarette smokers (35.48 years old; 39.4% female), of which 72 reported current daily dual use of an e-cigarette. Results indicated that Latinx dual users reported greater levels of pain severity (ηp2 = .12) and pain interference (ηp2 = .10) than exclusive combustible cigarette users. The study adds uniquely to the limited literature on the clinical importance of dual cigarette use in relation to pain severity and interference in that pain may serve as an important risk factor for the initiation and maintenance of dual use for increased analgesic nicotine effects.
RESUMO
Gain of Function refers to genetic modification to enhance certain properties of a biological agent. "Dual use research" refers to experiments which have a primary goal of benefitting humanity, but which could produce harm if misapplied. So, for example, a virus which was being genetically modified (GM) for altruistic reasons might become more transmissible or resistant to vaccines or antimicrobial medications. Such a GM virus has bioterrorism potential. The UN Biological Weapons Convention has not been universally approved and 10 States are not signatories to the Convention. The control of such experiments is variously controlled in certain jurisdictions but in Australia these experiments are well regulated through the Gene Technology Act 2000 (Cth), the National Health Security Act 2007 (Cth) and the Crimes (Biological Weapons) Act 1976 (Cth). The controls on such experiments in Europe and the United States are less precise. There are examples in the United States and Europe where the security provisions to contain microorganisms undergoing research including genetic modification have been breached. This threatens the health and safety of laboratory workers and the wider community.

Fast, accessible, and high-quality deoxyribonucleic acid (DNA) is fundamental to advancement in the life sciences that will drive forward fields such as agriculture, energy, and medicine. Despite their importance in accelerating global progress, bioscience research and biotechnologies can also be misused, endangering humans, animals, and the environment. The ability to accidentally or deliberately endow or enhance the pathogenicity of biological systems is of particular concern. Access to DNA sequences with a clear potential for dual use should be limited to responsible and identifiable groups with legitimate uses. Yet, none of the 195 countries party to the International Health Regulations have national laws that mandate this type of screening. Many DNA providers voluntarily screen orders and absorb increased costs, but this practice is not universally adopted for a variety of reasons. This article explores the incentives and regulatory structures that can bring the screening coverage of DNA orders toward 100%, which may include expedited orders for approved customers, better tools and technology for more efficient screening, funding requirements that grantees use screened DNA, and early education in biosecurity aimed at researchers and students. Ultimately, an incentive-based multistakeholder approach to DNA screening can benefit researchers, industry, and global health security.

The term Gain-of-Function (GoF) describes the gain of new functions by organisms through genetic changes, which can naturally occur or by experimental genetic modifications. Gain-of-Function research on viruses is enhancing transmissibility, virus replication, virulence, host range, immune evasion or drug and vaccine resistance to get insights into the viral mechanisms, to create and analyze animal models, to accelerate drug and vaccine development and to improve pandemic preparedness. A subset is the GoF research of concern (GOFROC) on enhanced potentially pandemic pathogens (ePPPs) that could be harmful for humans. A related issue is the military use of research as dual-use research of concern (DURC). Influenza and coronaviruses are main research targets, because they cause pandemics by airborne infections. Two studies on avian influenza viruses initiated a global debate and a temporary GoF pause in the United States which ended with a new regulatory framework in 2017. In the European Union and China, GoF and DURC are mainly covered by the legislation for laboratory safety and genetically modified organisms. After the coronavirus outbreaks, the GoF research made significant advances, including analyses of modified MERS-like and SARS-like viruses and the creation of synthetic SARS-CoV-2 viruses as a platform to generate mutations. The GoF research on viruses will still play an important role in future, but the need to clarify the differences and overlaps between GoF research, GOFROC and DURC and the need for specialized oversight authorities are still debated.

Life science research was analyzed for potential misuse in the 2004 report "Biotechnology Research in an Age of Bioterrorism". However, it was not until 2015 that the United States Government (USG) Institutional Dual Use Research of Concern (DURC) policy went into effect. Institutions receiving USG funding for life science research are required to scan their research portfolios for research involving one of 15 agents and subsequent 7 experimental effects described in the policy. In practice, this policy was implemented in a variety of ways with varying outcomes and lessons learned. First and foremost, reviewing research for potential DURC is a highly subjective process that differs depending on the risk tolerance, experience, and training of the individuals charged with reviewing research for an institution as well as the review process itself. The information being reviewed also lends to the subjectivity of the process, that is, the experimental data provided. It is difficult to determine whether research is potential DURC without experimental data. Any review process is hypothetical until there is data. Lastly, reviewers of the research should look beyond the research proposals, like how compounding existing research information can create new risks, potential use in other organisms or systems, or the creation of a roadmap that, for example, shows how to create a concerning organism or could be used in a pathogen.

To address real and perceived emerging risks originating from the ever-accelerating breakthroughs in life science research, the Dual Use Research of Concern (DURC) Panel Discussion, organized by Synbio Canada and the Alberta RNA Research and Training Institute (ARRTI), took place on June 23rd, 2021. It brought together six stakeholders from different levels of academic research, administration, governance, and science publishing to explore the current and future challenges in addressing DURC. Technological advancements within the life sciences, especially within the field of omics technology, make it difficult to apply a simple checklist for dual-use assessment and require continuous and integrated effort. Bottom-up approaches from within the scientific community are suggested by all stakeholders to enable efficient governance and address the true risks resulting from DURC, not just the alleged risks. To address such alleged risks, open and broadscale communication of DURC and its oversight policies may be required. At the same time, any form of open communication also contains the risk of information hazards, defined as potentially creating public fear or informing malicious actors. Here, an overview of the DURC panel and its outcomes is provided.

BACKGROUND: Adolescents who dual use ENDS with tobacco cigarettes are more likely to have an increased risk of developing dependence. Yet, little is understood about the factors driving dual use among adolescents. The current study sought to reveal the day-to-day socio-temporal contextual and community factors associated with adolescents' use of electronic nicotine delivery systems (ENDS), and how these factors predict dual use with tobacco cigarettes. METHODS: We collected ecological momentary assessments (EMA) from a sample of 50 adolescent past two-week vapers (ages 14-17 years old) over 14 days. Daily EMA data were collected on ENDS and tobacco cigarette use, as well as a range of contextual (i.e., motivations to vape, location of vaping, who with when vaping) and community factors (i.e., exposure to peers vaping, to adults vaping, to ENDS advertising, to ENDS warning messages). Our primary analyses were multilevel regressions, accounting for daily observations nested within individuals (N = 700 observations). RESULTS: Participants used ENDS exclusively on 44% of days and dual used ENDS and tobacco cigarettes on 8% of the days. Dual use days (versus exclusive ENDS use days) were associated with "vaping because tobacco use was prohibited" (OR = 34.65, p < .05). Also, dual use days (versus no use days) were associated with greater exposure to adults vaping (OR = 5.59, p < .05), peers vaping (OR = 7.48, p < .05), and (c) ENDS advertisements or promotions (OR = 2.12, p < .01), whereas exclusive use days (versus no use days) were only associated with greater exposure to peers vaping (OR = 2.58, p < .01). CONCLUSIONS: Results showed that exposure to peers and adults vaping and exposure to ENDS marketing were associated with same day dual use behaviors. And, that adolescents who dual used were motivated to use ENDS because they were easy to conceal. Findings support stricter regulation of ENDS marketing and for smoke-free air laws that include ENDS. In addition, these findings support prioritizing family- and school-based prevention programming that effectively communicates risk associated with ENDS use, including heightened risk of dual use and dependence. Such efforts can reduce the number of adolescents who use ENDS as well as the number who transition to tobacco cigarette use.

Dual use of conventional cigarettes and electronic cigarettes presents an emerging public health issue. Previous research has demonstrated a negative relationship between health literacy and conventional cigarette (CIG) use. However, the relationship between health literacy and e-cigarette (ECIG) use remains unclear. This studies examines the possible association of health literacy and CIG, ECIG, or dual use. A multinomial regression was used to model the association between health literacy and current CIG use, current ECIG use, or dual tobacco use status using state-optional data from the 2016 Behavioral Risk Factor Surveillance System (BRFSS; N = 40,404). One-third of the sample (N = 13,478; 33.3%) had initiated tobacco use. Approximately 36.6% of participants exclusively used cigarettes. A smaller proportion of participants were dual users of ECIG and CIGs (7.0%) and e-cigarette exclusive users (4.5%). After adjusting for covariates, higher levels of oral health literacy was associated with lower odds of current dual use. However, there was no significant association between written HL and either conventional cigarette use or electronic cigarette use or after adjusting for covariates. Oral messaging around the dangers of CIG use may be effective at lowering odds of CIG or dual use, especially for those with higher levels of HL. Further research is needed to examine how to best disseminate information regarding the health risks of ECIGs.

Background: Existing studies of dual use of electronic and combustible cigarettes either collected longitudinal data with long gaps in between waves or conducted ecological momentary assessment (EMA) over a short period of time. In recent years, the measurement burst design that embeds an EMA protocol in each wave assessment of a traditional longitudinal study has become more popular and yet conventional generalized linear mixed models (GLMM) have important limitations for handling data from this design.Objectives: This study proposed a new statistical method to analyze data from the measurement burst design.Methods: This new statistical method was designed to model the short-term (within-wave) as well as long-term (between-wave) changes and was validated by a simulation study. Secondary analysis was conducted to analyze data from 205 dual users (52% male) and 146 exclusive smokers (50% male) who participated in a recent study using the measurement burst design.Results: The simulation study shows that the proposed method can handle the gap between waves well and is also robust to nonlinear changes across waves. Although no short-term change in smoking was found, dual users reported a long-term reduction in cigarette use that was more rapid compared to exclusive smokers (ßË=-0.0127,p=.0167). Vaping more was associated with smoking less (ßË=-0.0058,p=.0054).Conclusion: The proposed method is highly applicable as it can be easily implemented by substance use researchers and the results can be straightforwardly interpreted. The results suggest that e-cigarette use may play a role in promoting a long-term reduction in smoking among dual users.
