[Primary prevention of computer game addiction in students of educational institutions]. / Pervichnaya profilaktika komp'yuternoi igrovoi zavisimosti u uchashchikhsya obshcheobrazovatel'nykh uchrezhdenii.

OBJECTIVE: To conduct the primary prevention of computer game addiction (PPCGA) in students of General education institutions (GEI), aimed at preventing the formation of CGA. MATERIAL AND METHODS: The study included 488 students in grades 7-10 of GEI aged 12-17 years (14.6±2.4 years), of which 393 adolescents, who made up the main group, received PPCGA and 95 - control, without PPCGA. RESULTS: Preventive measures were carried out without interrupting the educational process; they were carried out by addiction psychiatrists and medical psychologists. PPCGA was aimed at teaching students a healthy lifestyle, the development of their personal resources, the formation of skills to overcome problem situations, a change in the value attitude to computer games and the formation of alternative interests. In the main group, a decrease in the time interval spent by students at the computer was found (p<0.05). There was a decrease in the number of students (p<0.05), experiencing affective disorders when abstaining from the computer, including mild depression and subclinically expressed anxiety/depression, for whom computer games could lead to problems and negative consequences. An increase in the interval of time spent by students at the computer (p<0.05); an increase in the number of students experiencing affective disorders when abstaining from the computer (p<0.05); a trend towards the increase in the frequency of problems and delayed meetings and personal matters related to spending time at the computer; an increase in clearly uncommunicative (p<0.05) were found in the control group. CONCLUSIONS: Primary prevention of computer gaming increase the number of students who prefer a healthy lifestyle (physical education and sports, rational nutrition, sex education, family relationships) and reduce the number of people who prefer computer games as a form of leisure.

Efficacy of a Mobile App-Based Coaching Program for Addiction Prevention among Apprentices: A Cluster-Randomized Controlled Trial.

BACKGROUND: Addictive behaviors such as tobacco/e-cigarette smoking, at-risk alcohol consumption, cannabis use or compulsive internet use are common among apprentices. ready4life is a mobile app-based preventive intervention program for apprentices that promotes life skills and reduces risky behavior. The present study tested the efficacy of ready4life for addiction prevention among apprentices in Switzerland within a controlled trial. METHODS: Two-arm, cluster-randomized controlled trial including assessments at baseline and follow-up after 6 months. Participants of the intervention group received coaching by a conversational agent for 16 weeks. The main outcome measure was a composite score for addictive behaviors, which included (1) at-risk drinking, (2) tobacco/e-cigarette smoking, (3) cannabis use and (4) problematic internet use. RESULTS: A total of 2275 students from 159 vocational school classes in Switzerland, were invited for study participation. Of these, 1351 (59.4%) students with a mean age of 17.3 years and a male proportion of 56.6% provided informed consent to participate. The follow up assessment at month 6 was completed by 962 (71.2%) study participants. The results concerning the primary outcome showed a stronger decrease of addictive behaviors between baseline and follow up in the intervention group compared to the control group. In particular, significant effects were observed for at-risk drinking and problematic Internet use, while no significant effects were observed for tobacco/e-cigarette smoking and cannabis use. CONCLUSIONS: The majority of apprentices invited for program participation within vocational schools participated in the ready4life program for addiction prevention. The mobile app-based coaching was effective in reducing risk behaviors such as at-risk drinking and problematic Internet use in a group of adolescents who have an especially high risk of engaging in addictive activities.

[SBIRT model as a prevention strategy against addiction with and without substance in teenagers.] / El modelo SBIRT como estrategia de prevención de las adicciones con y sin sustancia en adolescentes.

A high prevalence of adolescent substance use, risky consumption patterns and the decrease in the age of initiation, together with the growth of non-substance addictions, represent a huge challenge for Public Health. This suggests the need for a change of focus in the work of the primary care settings, which must be more proactive in the early detection and intervention. Although there are some previous experiences in Spain, we do not have a duly standardised system, based on clinical practice and validated in consulting rooms, which could be used in a general, simple, and guaranteed manner. The SBIRT (Screening, Brief Intervention and Referral to Treatment) model, developed in the United States and conceived from a Public Health perspective, might represent such a paradigm shift. The aim of this paper was to provide researchers and professionals with a review of the available evidence in different countries, with a view to implementing it in Spain, where SBIRT remains a challenge. In addition, theoretical and technical foundations, and potential of the SBIRT are described. Not only its possible benefits and opportunities are put on the table, but also the shortcomings, limitations and needs that must be overcome for SBIRT implementation to be possible.

La alta prevalencia del consumo de sustancias entre los adolescentes, los preocupantes patrones de consumo y el descenso de las edades de inicio, junto al crecimiento de las adicciones sin sustancia, suponen uno de los grandes desafíos actuales en materia de Salud Pública. Ello sugiere la necesidad de un cambio de enfoque en la labor de los dispositivos de Atención Primaria (AP), que han de ser más proactivos en la detección e intervención precoz. Aunque en España existen algunas experiencias previas, no disponemos de una sistemática debidamente protocolizada, fundamentada clínicamente y validada en las consultas, que pueda ser utilizada de forma generalizada, sencilla y con garantías por los profesionales. El modelo SBIRT (Screening, Brief Intervention and Referral to Treatment), desarrollado en Estados Unidos y concebido desde un enfoque de Salud Púbica, representa ese cambio de paradigma. El objetivo de este trabajo, además de dar a conocer los fundamentos teóricos, técnicos y potencialidades del SBIRT, fue poner a disposición de investigadores y profesionales una revisión de la evidencia disponible en diferentes países, de cara a su posible implantación en España, donde a pesar de la existencia de experiencias precedentes puntuales, constituye todavía una cuenta pendiente. Se ponen sobre la mesa no sólo los posibles beneficios y oportunidades, sino también las carencias, limitaciones y necesidades que han de superarse para que la implementación del SBIRT sea posible.

The efficacy of Personalized Normative Feedback interventions across addictions: A systematic review and meta-analysis.

Personalized Normative Feedback (PNF) may help address addictive disorders. PNF highlights discrepancies between perceived and actual peer norms, juxtaposed against self-reported behavior. PNF can be self-directed and cost-efficient. Our study estimates the efficacy of PNF alone, and in combination with other self-directed interventions, to address frequency and symptom severity of hazardous alcohol use, problem gambling, illicit drug and tobacco use. We searched electronic databases, grey literature, and reference lists of included articles, for randomized controlled trials published in English (January 2000-August 2019). We assessed study quality using the Cochrane Risk of Bias tool. Thirty-four studies met inclusion criteria (k = 28 alcohol, k = 3 gambling, k = 3 cannabis, k = 0 tobacco). Thirty studies provided suitable data for meta-analyses. PNF alone, and with additional interventions, reduced short-term alcohol frequency and symptom severity. PNF with additional interventions reduced short-term gambling symptom severity. Effect sizes were small. PNF did not alter illicit drug use. Findings highlight the efficacy of PNF to address alcohol frequency and symptom severity. The limited number of studies suggest further research is needed to ascertain the efficacy of PNF for gambling and illicit drug use. Cost-effectiveness analyses are required to determine the scale of PNF needed to justify its use in various settings.

Testing Augmented Reality for Eliciting Cue-Provoked Urges to Smoke: Toward Moving Cue-Exposure Into the Real World.

BACKGROUND: Cue exposure for extinguishing conditioned urges to smoking cues has been promising in the laboratory, but difficult to implement in natural environments. The recent availability of augmented reality (AR) via smartphone provides an opportunity to overcome this limitation. Testing the ability of AR to elicit cue-provoked urges to smoke (ie, cue reactivity [CR]) is the first step to systemically testing the efficacy of AR for cue exposure therapy. OBJECTIVES: To test CR to smoking-related AR cues compared to neutral AR cues, and compared to in vivo cues. METHODS: A 2 × 2 within-subject design comparing cue content (smoking vs. neutral) and presentation modality (AR vs. in vivo) on urge response. Seventeen smokers viewed six smoking-related and six neutral cues via AR smartphone app and also six smoking and six neutral in vivo cues. Participants rated their urge to smoke and reality/co-existence of the cue. RESULTS: Average urge to smoke was higher following smoking-related AR images (Median = 7.50) than neutral images (Median = 3.33) (Z = -3.44; p = .001; d = 1.37). Similarly, average urge ratings for in vivo smoking-related cues (Median = 8.12) were higher than for neutral cues (Median = 2.12) (Z = -3.44; p = .001; d = 1.64). Also, greater CR was observed for in vivo cues than for AR cues (Z = -2.67, p = .008; d = .36). AR cues were generally perceived as being realistic and well-integrated. CONCLUSIONS: CR was demonstrated with very large effect sizes in response to AR smoking cues, although slightly smaller than with in vivo smoking cues. This satisfies the first criterion for the potential use of AR for exposure therapy. IMPLICATIONS: This study introduces AR as a novel modality for presenting smoking-related stimuli to provoke cue reactivity, and ultimately to conduct extinction-based therapy. AR cues presented via a smartphone have the advantage over other modes of cue presentation (pictures, virtual reality, in vivo, etc.) of being easily transportable, affordable, and realistic, and they can be inserted in a smokers' natural environment rather than being limited to laboratory and clinic settings. These AR features may overcome the generalizability barriers of other methods, thus increasing clinical utility for cue exposure therapies.

Prerequisites for stakeholder framework: Consumer advocacy and health protection in the digital industry. •.

The World Health Organization (WHO) included gaming disorders in International Classification of Disease-11th (ICD-11) on May 25, 2019. Since then, some academics and the gaming industry have continued to argue over the health system's response to online addictive behaviors. Under these circumstances, a framework involving groups representing various interests is needed to derive a reasonable solution to the dispute over the inclusion of gaming disorders in ICD-11. For this framework to work effectively, it is necessary to agree on consistent and advanced research findings that harms related to the excessive use of digital devices or content continue to occur empirically all over the world and that addictive use constitutes a primary addictive disorder. The problematic risk taking involving emerging technologies may include not only health risks from addictive use, but also more general harms associated with digital ethics and norms such as privacy and transparent money transactions. An understanding of a public health model of addiction is required to reduce harms associated with online addictive behavior that exist behind risk taking. Such harms are also mediated by excessive use, excessive money spending, and exposure to addictive content such as violence and pornography. Major stakeholders and their roles can be derived more effectively based on these conceptual models and parameters of harms. In conclusion, the context of the proposed stakeholder framework should be further optimized on the basis of two principles: (1) advocating consumer rights as a general and standard approach to digital products; and (2) protecting consumers' health from harms related to addictive behaviors.

Efficacy of a smartphone-based coaching program for addiction prevention among apprentices: study protocol of a cluster-randomised controlled trial.

BACKGROUND: A large proportion of apprentices shows addictive behaviours like cigarette smoking, alcohol, cannabis, or compulsive Internet use, others do not show such behaviours at all. ready4life is a smartphone application-based coaching program for apprentices, which takes into account the heterogeneity of adolescent addictive behaviour by promoting life skills and reducing risk behaviours. The main objective of the planned study is to test the efficacy of ready4life for addiction prevention among apprentices in Switzerland within a controlled trial. METHODS/DESIGN: The efficacy of the ready4life coaching program will be tested in comparison to an assessment only control group, within a cluster-randomised controlled trial with one follow-up assessment after 6 months. At the beginning of the program, participants of the intervention group will receive an individual profile, showing areas in which they have sufficient resources and in which there is a need for coaching. Based on this feedback, they can select two out of the following six program modules: stress, social skills, Internet use, tobacco/e-cigarettes, cannabis, and alcohol. Participants of the intervention group will receive individualised coaching by a conversational agent (chatbot) for a period of four months. The coaching relies on motivational and social-cognitive principles of behaviour change. Within weekly dialogues, the coach provides individually tailored information in different formats, such as videoclips, texts, or pictures. Study participants will be 1318 apprentices with a minimum age of 15, recruited in approximately 100 vocational school classes in Switzerland. Primary outcome will be a composite measure for addictive behaviours including (1) at risk-drinking, (2) tobacco/e-cigarette smoking, (3) cannabis use, and (4) problematic Internet use. DISCUSSION: The study will reveal whether this universally implementable but individually tailored intervention approach is effective in preventing the onset and escalation of addictive behaviors among apprentices.

Ultraprocessed Food: Addictive, Toxic, and Ready for Regulation.

Past public health crises (e.g., tobacco, alcohol, opioids, cholera, human immunodeficiency virus (HIV), lead, pollution, venereal disease, even coronavirus (COVID-19) have been met with interventions targeted both at the individual and all of society. While the healthcare community is very aware that the global pandemic of non-communicable diseases (NCDs) has its origins in our Western ultraprocessed food diet, society has been slow to initiate any interventions other than public education, which has been ineffective, in part due to food industry interference. This article provides the rationale for such public health interventions, by compiling the evidence that added sugar, and by proxy the ultraprocessed food category, meets the four criteria set by the public health community as necessary and sufficient for regulation-abuse, toxicity, ubiquity, and externalities (How does your consumption affect me?). To their credit, some countries have recently heeded this science and have instituted sugar taxation policies to help ameliorate NCDs within their borders. This article also supplies scientific counters to food industry talking points, and sample intervention strategies, in order to guide both scientists and policy makers in instituting further appropriate public health measures to quell this pandemic.

Considering existing classic and contemporary proposals for preventing online addiction problems: Some old recipes for new problems. •.

This commentary examines the proposed framework in relation to current policy options and preventive strategies and adds classical prevention and ecological models to tackle internet use-related addiction problems. Specifically, it highlights the preventive developments regarding contributions to promote the healthy use of technologies, and the need of designing and testing prevention strategies targeting the incidence, prevalence and severity of these problems at all population levels. In summary, to start preventing and minimising harms due to the problematic and addictive use of emerging technologies, we already have old models we can apply to these new problems to ensure secure behaviours through the technologies, and enhance users' wellness and quality of life.

Perceptions of U.S. and Canadian Cannabis Package Warnings Among U.S. Adults.

BACKGROUND: Cannabis warning labels can communicate risks, but there is little research on warning perceptions and differences by product type. METHODS: In a 2019 online survey, 1,000 U.S. adults (500 cannabis users and 500 cannabis non-users who used tobacco) were randomly assigned to view no warning or one of four U.S. or Canadian warnings displayed on images of packaging for dried flower or edible cannabis. The warnings described cannabis risks related to psychosis, addiction, lack of FDA oversight, and impaired driving. We used linear regression to examine perceptions of warnings and product harm as a function of product type (dried or edible) and warning. We examined which warning participants selected as most effective for discouraging youth use and impaired driving. RESULTS: Participants found the addiction warning (cannabis users: B = -1.04, p < 0.001; cannabis non-users: B = 1.17, p < 0.001) and psychosis warning (users: B = -0.65, p < 0.05; non-users: B = -0.71, p < 0.05) less believable than the driving warning but indicated that they learned more from the psychosis warning than the driving warning (users: B = 0.88, p < 0.01; non-users (B = 1.60, p < 0.001). Participants viewing any warning considered smoking cannabis to be more harmful than those viewing no warning (all p < 0.05). The psychosis warning was most frequently selected as the best warning for discouraging youth use. CONCLUSIONS: Warnings have the potential to educate consumers and impact cannabis harm perceptions. Warnings have similar effects across product types, potentially eliminating the need for product type-specific warnings. The association of cannabis use with risk for psychosis, a topic addressed in Canadian warnings, could be a useful topic of focus in U.S. warnings.

Nalfurafine modulates the reinforcing effects of oxycodone in male and female adolescent C57BL/6J mice.

Addiction to prescription opioid, such as oxycodone, has affected millions of adolescents and young adults. Kappa opioid receptor (KOP-r) agonist can counterbalance the euphoria effects of mu opioid agonists like oxycodone. Nalfurafine is a KOP-r agonist. The current study examined how nalfurafine affected the reinforcing-effect of oxycodone in adolescent male and female mice using intravenous self-administration (SA) and conditioned place preference (CPP) paradigms. Adolescent mice (5 week-old) first received surgery for catheter implantation. After recovery, mice were then placed into the SA chambers and allowed to self-administer oxycodone, 2 h per day for 14 days. Following 14-day oxycodone SA, mice were injected with saline and a single dose of nalfurafine (10, 20, 30, 40 µg/kg, s.c.) 10 min before each oxycodone SA session for 5 consecutive days. The mice were then injected with Nor-BNI (10 mg/kg, i.p.) 24 h before oxycodone SA following injection of nalfurafine (40 µg/kg, s.c.). Separate groups of male and female adolescent mice underwent oxycodone CPP or hot plate test with or without nalfurafine pre-injection. Nalfurafine decreased oxycodone SA in a dose dependent manner. Nor-BNI blocked the effect of nalfurafine on oxycodone SA. Nalfurafine significantly attenuated the oxycodone-induced hyperlocomotor activities and CPP, but enhanced oxycodone-induced analgesia. In conclusion, nalfurafine reduced the reinforcing effects of oxycodone in male and female adolescent mice. Nalfurafine also increased oxycodone-induced antinociception.

Realist evaluation of a theory-based life skills programme aiming to prevent addictive behaviours in adolescents: the ERIEAS study protocol.

INTRODUCTION: Adolescence is a sensitive life stage during which tobacco, alcohol and cannabis are used as ways to learn and adopt roles. There is a great deal of interest in substance use (SU) prevention programmes for young people that work to change representations of these products and help with mobilisation of life skills. Unfortunately, few existing programmes are evidence-based.In France, a programme called Expériences Animées (EA, Animated Experiences) has been developed, inspired by life skills development programmes that have been proven to be successful. The EA programme uses animated short movies and talks with high school and secondary school pupils about the use of psychoactive substances and addictions. By allowing life skills mobilisation and modifying representations and beliefs about SU, it is aimed at delaying initiation of use of psychoactive substances, preventing adolescents from becoming regular consumers, reducing the risks and harms related to the use of these substances and opening the way for adapted support measures.We are interested in understanding how, under what circumstances, through which mechanisms and among which adolescents the EA programme works. Therefore, we have developed the ERIEAS study ('Evaluation Réaliste de l'Intervention Expériences Animées en milieu Scolaire'; Realist Evaluation of the EA Intervention in Schools). METHODS AND ANALYSIS: EA will be conducted in 10 schools. A multi-case approach will be adopted with the aim of developing and adjusting an intervention theory. The study comes under the theory-driven evaluation framework. The investigation methodology will include four stages: (i) elaboration of a middle-range theory; (ii) data collection for validating/adjusting the theory; (iii) data analysis; and (iv) refinement and adjustment of the middle-range theory and definition of the programme's key functions. ETHICS AND DISSEMINATION: The study will provide evidence-based results to health authorities to help in the rollout of health promotion strategies in schools. It will provide knowledge about the strategic configurations most suitable for leading to life skills mobilisation and change young people's representations about SU. The project will be carried out with full respect of current relevant legislation (eg, the Charter of Fundamental Rights of the European Union) and international conventions (eg, Helsinki Declaration). It follows the relevant French legislation of the research category on interventional research protocol involving the human person. The protocol was approved by the Comité et Protection des Personnes (CPP), that is, Committee for the Protection of Persons CPP SUD-EST VI n°: AU 1525 and was reported to the Agence Française de Sécurité Sanitaire des Produits de Santé (ANSM) that is, the French National Agency for the Safety of Health Products. It is in conformity with reference methodology MR003 of Bordeaux University Hospital (CNIL n° 2 026 779 v0).Trial registration detailsThis research has been registered on ClinicalTrials.gov (No. NCT04110626).The research project is registered in the European database ID-RCB (No. 2019-A01003-54).

Screening for Problematic Internet Use.

Problematic Internet use (PIU) by adolescents is of growing concern among both parents and pediatricians. Early controversies may have contributed to challenges in defining and measuring PIU. A variety of screening tools have evolved, aligned with different constructs of PIU, although a validated screening tool does exist. Current data and American Academy of Pediatrics policy reflect evidence-driven screening for PIU for all youth.

Mapping and comparing French people's positions regarding restrictive control policies: a pilot study.

BACKGROUND: Public authorities resort to various control policies in order to curb the prevalence of unhealthy behaviors. As these policies can only succeed to the extent that people agree with them, this study mapped French people's positions regarding restrictive control policies in general. METHOD: A sample of 344 adults (among them health professionals and lawyers) were presented with 54 vignettes depicting a control policy. Each vignette contained four pieces of information: the type of addictive behavior targeted (smoking, drinking, or gambling), the nature of preventive measures (e.g., information campaigns), the degree of regulative measures (e.g., prohibition to minors), and the severity of sanctions. RESULTS: Through cluster analysis, eight qualitatively different positions were found: Never acceptable (9%), Weak or moderate regulation (5%), Moderate regulation associated with strong prevention (11%), Strong or moderate regulation (11%), Strong regulation in association with strong prevention (23%), Moderate sanctions in association with strong prevention and moderate regulation (9%), Severe sanctions (9%), and Always acceptable (9%). Some participants (14%) expressed no opinion at all. CONCLUSION: French people's positions regarding control policies were extremely diverse. Regarding tobacco, however, one type of policy would likely be supported by a majority of people: Moderate regulation associated with at least a moderate level of prevention and low-level sanctions. Regarding alcohol, an acceptable position would be: Moderate regulation associated with at least a moderate level of prevention and high-level sanctions. Regarding gambling, an acceptable position would be: Strong regulation associated with at least a moderate level of prevention and low-level sanctions.

Ifenprodil Attenuates Methamphetamine-Induced Behavioral Sensitization Through the GluN2B-PP2A-AKT Cascade in the Dorsal Striatum of Mice.

Drug addiction can be described as a chronic and relapsing brain disease. Behavioral sensitization is believed to share similar mechanisms with relapse. Our previous studies have demonstrated that ifenprodil could attenuate methamphetamine (METH)-induced behavioral sensitization. However, the mechanism underlying this process has not been fully investigated. Protein phosphatase 2A (PP2A) is a conserved serine/threonine protein phosphatase that has been linked to many neurological diseases; however, there are few reports about PP2A in the context of drug addiction. In this study, we measured the level of phosphorylated (p-) GluN2B (Serine; Ser 1303), PP2A/B (a regulatory subunit of PP2A), and PP2A/C (a catalytic subunit of PP2A) in different brain regions such as the prefrontal cortex (PFc), nucleus accumbens (NAc), dorsal striatum (DS), and hippocampus (Hip). We also used ifenprodil, a selective antagonist of GluN2B to clarify the relationship between GluN2B and PP2A. The results showed that METH increased the level of p-GluN2B (Ser 1303) and PP2A/B in the DS and ifenprodil blocked this increase. We further examined the interaction between PP2A/B and PP2A/C in the DS and found that METH treatment increased the interaction between PP2A/B and PP2A/C, which was also blocked by ifenprodil. Then, we explored the pathway downstream of PP2A in the DS and found that p-AKT (Threonine; Thr 308) but not p-AKT (Ser 473) was dephosphorylated by PP2A. Taken together, these results indicated that the GluN2B-PP2A-AKT cascade was involved in METH-induced behavioral sensitization.

Reactions to electronic nicotine delivery system (ENDS) prevention messages: results from qualitative research used to inform FDA's first youth ENDS prevention campaign.

BACKGROUND: Youth e-cigarette use is a major public health concern. Large-scale tobacco prevention campaigns are a proven strategy to prevent tobacco use. There is a gap in understanding what types of e-cigarette prevention messages might be most effective. This study addresses this gap by reporting youth reactions to health messages aimed at preventing e-cigarette use. METHODS: In 2018, twenty-four focus groups, with 159 teens (12-17) at risk for or experimenting with e-cigarettes were conducted in four cities across the USA. During focus groups, youth responded to creative concepts dealing with (1) the addictive nature of e-cigarettes, (2) the fact that e-cigarettes come in flavours, which may encourage youth initiation, and nicotine which may lead to addiction, or (3) that youth who use e-cigarettes are more likely to use cigarettes. Youth also gave feedback to specific facts about harmful and potentially harmful chemicals in e-cigarettes. Transcripts were analysed using thematic analysis. RESULTS: Messages focusing on addiction alone did not resonate with participants. While youth found the idea that e-cigarettes may contain nicotine and can be addictive believable, with many describing personal experiences of addiction, they questioned how bad this really was, comparing addiction to e-cigarettes to things like being addicted to food. Participants wanted more information about negative consequences of vaping. Concepts paired with strong health effects messages resonated with participants. CONCLUSION: These focus groups clarified which e-cigarette prevention messages might be most persuasive to teens. Youth in this study responded favourably to messages stating specific health consequences of e-cigarette use.

Advice to the European Commission as Regards Type and Criteria for Comprehensive Studies to Be Requested From Manufacturers: The Opinion of the Scientific Committee on Health, Environmental, and Emerging Risks (SCHEER).

The European Commission has established a priority list of 15 additives contained in cigarettes and roll-your-own tobacco subject to enhanced reporting obligations. The European Union (EU) Tobacco Products Directive (TPD) prescribes that Member States shall require manufacturers and importers of tobacco products to carry out comprehensive studies on these additives to assess their contribution to any of the properties listed in Article 6 of the TPD: toxicity or addictiveness, characterizing flavor, inhalation facilitation, nicotine uptake, and carcinogenic, mutagenic, or toxic for reproduction. The Scientific Committee on Health, Environmental, and Emerging Risks (SCHEER) has provided guidance on the type and criteria for comprehensive studies, and on the most suitable methodologies to test these 15 tobacco additives as well as additives on future updated lists. The SCHEER proposes a stepwise strategy as the most pragmatic and efficient way to assess the effects of tobacco additives. In addition to proposing specific steps and tests to be considered by industry, some general criteria were also identified such as no comparative testing (testing cigarettes with and without the additive) and no animal studies. As tobacco additives have no benefits for health, but rather may promote use of and addiction to an extremely toxic product, a risk-benefit analysis is not the appropriate paradigm for assessing the additive. When comprehensive studies confirm that additives have any of the properties listed in Article 6 of the TPD, regulatory actions should be considered. If uncertainties cannot be solved by comprehensive studies, the SCHEER recommends that the assessors consider the worst-case evaluation. IMPLICATIONS: In this article, the SCHEER proposes a stepwise strategy to assess (1) the toxic and addictive effects, (2) the characterizing flavor, and (3) facilitating inhalation properties of tobacco additives. The proposed steps and tests provide guidance to (1) Member State on which comprehensive studies should be requested and (2) tobacco industry on which strategy of testing should be applied to address the request and to prepare reports to be sent to the relevant authorities for the evaluation of tobacco additives "safety" to comply with the Tobacco Products Directive 2014/40/EU.

Vaping: The new wave of nicotine addiction.

Vaping devices, introduced to the US market in 2007 as aids for smoking cessation, have become popular among youth and young adults because of their enticing flavors and perceived lack of negative health effects. However, evidence is emerging that vaping may introduce high levels of dangerous chemicals into the body and cause severe lung injury and death. This article reviews the history and prevalence of vaping and available research on its health effects and efficacy in smoking cessation, and proposes recommendations for clinicians and legislators to reduce harms associated with vaping.

Relationships of homophobic bullying during childhood and adolescence with problematic internet and smartphone use in early adulthood among sexual minority men in Taiwan

Abstract Background Mental health disparity in sexual minorities is a crucial clinical and public health issue worldwide. A total of 500 homosexual or bisexual men aged between 20 and 25 years participated in this study. Objectives The aims of the study were to examine the relationships of victimization of traditional and cyber homophobic bullying during childhood and adolescence with problematic internet and smartphone use and activities during early adulthood among sexual minority men in Taiwan. Methods The seveirities of problematic internet and smartphone use and activities in early adulthood were compared between victims and non-victims of bullying. The severities of problematic internet and smartphone use were also compared among the groups of various types of bullying as well as among the groups of various persistence durations of being bullied. Results Victims of traditional and cyber homophobic bullying had more severe problematic internet and smartphone use than non-victims. Victims of multi-type bullying had more severe problematic internet use than victims of single-type bullying. Prolonged victimization was significantly associated with problematic internet and smartphone use. Discussion: Victimization of traditional and cyber homophobic bullying during childhood and adolescence predicts problematic internet and smartphone use during early adulthood among sexual minority men.

U.S. Adults' Attitudes Toward Lowering Nicotine Levels in Cigarettes.

INTRODUCTION: This study assessed U.S. adults' attitudes toward lowering the nicotine levels in cigarettes to make them less addictive. METHODS: Data from the 2018 SummerStyles, a web-based panel survey of U.S. adults aged ≥18 years (n=4,037) fielded in June-July, were analyzed in 2018. Respondents were asked: Do you favor or oppose requiring cigarette makers to lower the nicotine levels in cigarettes so that they are less addictive? Responses were strongly favor, somewhat favor, somewhat oppose, and strongly oppose. Sociodemographic correlates of favorability (strongly favor or somewhat favor) were assessed using multivariable Poisson regression. RESULTS: Eighty-one percent of adults in 2018 strongly or somewhat favored requiring cigarette makers to lower the nicotine levels in cigarettes to make them less addictive, including 80.6% of current cigarette smokers, 84.3% of former smokers, and 81.3% of never smokers. Favorability was 71.5% among current noncigarette tobacco product users and 81.9% among nonusers. Following adjustment, slight variations in favorability existed by sex, age, race/ethnicity, and other tobacco product use. CONCLUSIONS: Most adults favor requiring cigarette makers to lower the nicotine levels in cigarettes, including 8 in 10 current cigarette smokers. These findings can help inform the U.S. Food and Drug Administration's recent proposal to pursue a nicotine reduction standard for cigarettes.
