Abstract
OBJECTIVE Investigate the effect of change talk (CT) within successive brief motivational interventions (BMIs) as a mechanism of change for alcohol use. METHOD We conducted a secondary analysis of data from a randomized controlled trial in which 344 young adults (18-35 years old) admitted to a Swiss emergency department with alcohol intoxication received either BMI (N = 171) or brief advice (N = 173). Participants with a baseline audio-recorded BMI were included (N = 140; median age 23 [Q1-Q3: 20-27], 72.9% men). Up to three booster sessions by phone were offered at 1 week, 1 month, and 3 months. Percent CT and CT Average Strength were used as predictor variables. The outcome was the number of heavy drinking days (HDD) over the 30 days prior to research assessments at 1-, 3-, 6-, and 12-month follow-up. A latent growth curve modeling framework was first used to estimate predictor and outcome variable growth parameters (i.e., intercept and slope) over time, and then to regress HDD growth parameters on CT growth parameters. RESULTS CT increased specifically from baseline to the 1-week booster session and thereafter remained stable. Higher baseline CT was associated with lower HDD at 1 month (Percent CT: b = -0.04, 95% confidence interval [-0.06, -0.01]; Average Strength: b = -0.99 [-1.67, -0.31]). An increase in CT from baseline to the 1-week booster session was related to a decrease in HDD from 1 month to 12 months (Percent CT: b = -0.08 [-0.14, -0.03]; Average Strength: b = -2.29 [-3.52, -1.07]). CONCLUSIONS Both baseline CT and CT trajectory over the first week are meaningful predictors of HDD. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Abstract
BACKGROUND Given alcohol and/or other drug (AOD) use occurs among people with HIV (PWH), we examined its association with falls and fall-related outcomes and whether frailty moderates the association. SETTING Northeastern US city. METHODS We analyzed an observational cohort of PWH with current or past AOD use. Alcohol measures were any past 14-day heavy use, average alcohol/day, and days with heavy use. Drug use measures were past 30-day illicit use of cocaine, opioids, and sedatives. Repeated cross-sectional associations were estimated with separate multivariable generalized estimating equation regression models for each fall-related outcome. RESULTS Among PWH (n = 251; mean age 52 [SD = 10]), 35% reported heavy alcohol use, 24% cocaine, 16% illicit opioids, 13% illicit sedatives, and 35% any fall; 27% were frail. Heavy alcohol use was associated with a fall (AOR = 1.49, 95% CI: 1.08 to 2.07), multiple falls (AOR = 1.55 95% CI: 1.10 to 2.19), and fall/fracture-related emergency department visit or hospitalization (AOR = 1.81, 95% CI: 1.10 to 2.97). Higher average alcohol/day and more heavy drinking days were associated with multiple falls. Illicit sedative use was associated with a fall, multiple falls, and emergency department visit/hospitalization and opioid use with fracture. Frailty moderated the association of heavy alcohol use and a fall (AOR = 2.26, 95% CI: 1.28 to 4.01 in those frail) but not in those not frail. CONCLUSION The effect of AOD use on falls and fall-related outcomes was most pronounced with alcohol, particularly among frail PWH. Heavy alcohol, illicit sedative, and illicit opioid use are high-priority targets for preventing falls and fall-related consequences for PWH.

Abstract
OBJECTIVE To estimate the effects of providing access to an alcohol intervention based on a smartphone. DESIGN Randomised controlled trial.. SETTING Four higher education institutions in Switzerland. PARTICIPANTS 1770 students (≥18 years) who screened positive for unhealthy alcohol use (ie, a score on the alcohol use disorders identification test-consumption (AUDIT-C) of ≥4 for men and ≥3 for women) were randomly assigned by 1:1 allocation ratio in blocks of 10. INTERVENTION Providing access to a brief, smartphone based alcohol intervention. OUTCOME MEASURES The primary outcome studied was number of standard drinks per week at six months and the secondary outcome was number of heavy drinking days (past 30 days). Additional outcomes were maximum number of drinks consumed on one occasion, alcohol related consequences, and academic performance. Follow-up assessments occurred at months three, six, and 12. Data were analysed by intention to treat and by using generalised linear mixed models with random intercepts for the recruitment site and participants nested within the recruitment site, and with intervention (v control), time (three months v six months; 12 months v six months), and baseline outcome values as fixed effects. RESULTS Between 26 April 26 2021 and 30 May 2022, 1770 participants (intervention group (n=884); control group (n=886)) were included. Mean age was 22.4 years (standard deviation 3.07); 958 (54.1%) were women; and 1169 (66.0%) were undergraduate students, 533 (30.1%) were studying for a master's degree, 43 (2.4%) were studying for a doctorate, and 25 (1.4%) were students of other higher education programme. The baseline mean number of standard drinks per week was 8.59 (standard deviation 8.18); the baseline number of heavy drinking days was 3.53 (4.02). Of 1770 participants, follow-up rates were 1706 (96.4%) at three months, 1697 (95.9%) at six months, and 1660 (93.8%) at 12 months. Of 884 students randomly assigned to the intervention group, 738 (83.5%) downloaded the smartphone application. The intervention had a significant overall effect on the number of standard drinks per week (incidence rate ratio 0.90 (95% confidence interval 0.85 to 0.96)), heavy drinking days (0.89 (0.83 to 0.96)), and the maximum number of drinks consumed on one occasion (0.96 (0.93 to 1.00), P=0.029), indicating significantly lower drinking outcomes in the intervention group than in the control group during the follow-up period. The intervention did not affect alcohol related consequences or academic performance. CONCLUSIONS Providing access to the smartphone application throughout the 12 month follow-up was effective at limiting the average drinking volume of university students who had self-reported unhealthy alcohol use at baseline.

Abstract
BACKGROUND Research has not identified which patients optimally benefit from brief Motivational Interviewing (bMI) for heavy drinking when delivered to young adults in the Emergency Department (ED). METHODS We conducted secondary analyses of data from a randomized controlled trial in which 344 young adults (18-35 years) presenting to the ED with alcohol intoxication received either bMI or Brief Advice (BA, control group). We used Latent Class Analysis to derive participants' profiles from baseline characteristics (i.e., sex, age, severity of alcohol use disorder, attribution of ED admission to alcohol use, importance, and confidence to change, cognitive discrepancy, anxiety, depression, and trait reactance). We then conducted a moderation analysis to assess the number of heavy drinking days at short-term (1-month) and long-term (12-month) follow-up using negative binomial regressions with interactions between the intervention and derived classes. RESULTS Fit statistics indicated that a 4-class solution best fit the data. Class 3 (high severity, importance and discrepancy, and low confidence and anxiety) benefitted more from bMI than BA at short- and long-term follow-up than Class 1 (younger; lowest severity, importance, discrepancy, reactance, anxiety and depression, and highest confidence). Class 2 (older; highest severity, importance, discrepancy, reactance, anxiety and depression, and lowest confidence) also benefitted more from bMI than BA than did Class 1 at short-term follow-up. In these significant contrasts, Class 1 benefitted more from BA than bMI. There were no significant interactions involving Class 4 (more likely to be women; low severity; high levels of anxiety, depression, and reactance). CONCLUSIONS This study identified the patient profiles that benefitted more from bMI than BA among nontreatment-seeking young adults who present intoxicated to the ED. The findings have implications for intervention design and argue for the importance of research aimed at developing intervention content tailored to patient profiles.

Abstract
BACKGROUND Alcohol use has been linked to worse human immunodeficiency virus (HIV) immunologic/virologic outcomes, yet few studies have explored the effects of alcohol use disorder (AUD). This study assessed whether AUD severity is associated with HIV viral suppression and CD4 count in the three cohorts of the Uganda Russia Boston Alcohol Network for Alcohol Research Collaboration on HIV/AIDS (URBAN ARCH) Consortium. METHODS People with HIV (PWH) in Uganda (n = 301), Russia (n = 400), and Boston (n = 251), selected in-part based on their alcohol use, were included in analyses. Logistic and linear regressions were used to assess the cross-sectional associations between AUD severity (number of DSM-5 diagnostic criteria) and (1) HIV viral suppression, and (2) CD4 count (cells/mm3 ) adjusting for covariates. Analyses were conducted separately by site. RESULTS The proportion of females was 51% (Uganda), 34% (Russia), and 33% (Boston); mean age (SD) was 40.7 (9.6), 38.6 (6.3), and 52.1 (10.5), respectively. All participants in Uganda and all but 27% in Russia and 5% in Boston were on antiretroviral therapy. In Uganda, 32% met criteria for AUD, 92% in Russia, and 43% in Boston. The mean (SD) number of AUD criteria was 1.6 (2.4) in Uganda, 5.6 (3.3) in Russia, and 2.4 (3.1) in Boston. Most participants had HIV viral suppression (Uganda 92%, Russia 57%, Boston 87%); median (IQR) CD4 count was 673 (506, 866), 351 (201, 542), and 591 (387, 881), respectively. In adjusted models, there were no associations between AUD severity and HIV viral suppression: adjusted odds ratios (AOR) (95%CI) per 1 additional AUD criterion in Uganda was 1.08 (0.87, 1.33); Russia 0.98 (0.92, 1.04); and Boston 0.95 (0.84, 1.08) or CD4 count: mean difference (95%CI) per 1 additional criterion: 5.78 (-7.47, 19.03), -3.23 (-10.91, 4.44), and -8.18 (-24.72, 8.35), respectively. CONCLUSIONS In three cohorts of PWH, AUD severity was not associated with HIV viral suppression or CD4 count. PWH with AUD in the current era of antiretroviral therapy can achieve virologic control.

Abstract
BACKGROUND Despite considerable efforts devoted to the development of prevention interventions aiming at reducing unhealthy alcohol use in tertiary students, their delivery remains often challenging. Interventions including information technology are promising given their potential to reach large parts of the population. OBJECTIVE This study aims to develop a secondary prevention smartphone app with an iterative qualitative design involving the target population. METHODS The app development process included testing a first prototype and a second prototype, developed based on the results of 2 consecutive qualitative assessments. Participants (aged ≥18 years, screened positive for unhealthy alcohol use) were students from 4 tertiary education institutions in the French-speaking part of Switzerland. Participants tested prototype 1 or prototype 2 or both and provided feedback in 1-to-1 semistructured interviews after 2-3 weeks of testing. RESULTS The mean age of the participants was 23.3 years. A total of 9 students (4/9 female) tested prototype 1 and participated in qualitative interviews. A total of 11 students (6/11 female) tested prototype 2 (6 who tested prototype 1 and 5 new) and participated in semistructured interviews. Content analysis identified 6 main themes: "General Acceptance of the App," "Importance of the Targeted and Relevant App Content," "Importance of Credibility," "Importance of the App Usability," "Importance of a Simple and Attractive Design," "Importance of Notifications to Ensure App Use over Time." Besides a general acceptance of the app, these themes reflected participants' recommendations toward increased usability; to improve the design; to include useful and rewarding contents; to make the app look serious and credible; and to add notifications to ensure its use over time. A total of 11 students tested prototype 2 (6 who tested prototype 1 and 5 new) and participated in semistructured interviews. The 6 same themes emerged from the analysis. Participants from phase 1 generally found the design and content of the app improved. CONCLUSIONS Students recommend prevention smartphone apps to be easy to use, useful, rewarding, serious, and credible. These findings may be important to consider when developing prevention smartphone apps to increase the likelihood of app use over time.

Abstract
Addictions appear everywhere, mutate, transform with new products and behaviors, playing on our painstaking efforts to try to control them. Drawn into this current, the impression that dominates invites more to understand and to coax rather than to fight. Addictions are our condition, let's deal with it, rather than fight against them. It is therefore a question of knowing the products, that everyone can identify their level of risk, and of giving as many tools as possible, at any age, whatever the behavior or the product. This article shows us that there is a lot to do, from school benches to liver transplantation. There is also a lot to discover, in the recognition of the therapeutic virtues, of cannabinoids for example or even in their prescription, of pharmaceutical heroin for example, sometimes by far the best option.

Abstract
OBJECTIVE Polysubstance use is common among people with HIV infection (PWH) and with substance use disorder (SUD), but its effects are understudied. We aimed to identify polysubstance use patterns over time and assess their associations with HIV disease severity. METHOD In 233 PWH with current or past SUD, latent class analysis identified polysubstance use patterns based on the Alcohol Use Disorders Identification Test-Consumption and past-30-day use of cannabis, cocaine, opioids, and tranquilizers at baseline. We categorized changes in use patterns and tested associations between those changes and CD4 count and HIV viral suppression at 12 months in linear and logistic regressions. RESULTS Three patterns were identified at baseline: 18% did not use any substance (NONE--a priori defined); 63% used mostly cannabis and alcohol (CA); and 19% used opioids along with other drugs, including cocaine, tranquilizers, cannabis, and alcohol (MULTI). At 12 months, 40% moved from a high to a lower substance use class (MULTI to CA, either to NONE) or remained as NONE, 43% were in CA both times and 17% increased (NONE to CA, either to MULTI) or remained as MULTI. The adjusted mean CD4 count (for baseline covariates and baseline CD4 count) was significantly lower among participants increasing or remaining in MULTI (523, 95% CI [448, 598], cells/mm3) compared with those who decreased/abstained throughout (607, 95% CI [552, 663], p = .02). No significant difference was observed for HIV viral suppression. CONCLUSIONS We identified distinct polysubstance use patterns among PWH with SUD: cannabis/alcohol and opioids with alcohol and other drugs. Changes over time toward fewer substances/no use were associated with lower HIV disease severity based on CD4 count but not based on HIV viral suppression.

Abstract
Introduction This study examines normative misperceptions in a sample of participants recruited for a brief intervention trial targeting risky cannabis use. Methods Participants who were concerned about their own risky cannabis use were recruited to help develop and evaluate intervention materials. At baseline, participants reported on their own cannabis use and provided estimates of how often others their gender and age used cannabis in the past 3 months. Comparisons were made between participants estimates of others cannabis use with reports of cannabis use obtained from a general population survey conducted during a similar time period. Results Participants (N = 744, mean age = 35.8, 56.2% identified as female) largely reported daily or almost daily cannabis use (82.4%). Roughly half (55.3%) of participants estimated that others their age and gender used cannabis weekly or more often in the past 3 months, whereas the majority of people in the general population reported not using cannabis at all. Conclusions Normative misperceptions about cannabis use were common in this sample of people with risky cannabis use. Limitations and possible future directions of this research are discussed, as well as the potential for targeting these misperceptions in interventions designed to motivate reductions in cannabis use.

Abstract
BACKGROUND AND AIMS The alcohol purchase task (APT), which presents a scenario and asks participants how many drinks they would purchase and consume at different prices, generates indices of alcohol reward value that have shown robust associations with alcohol-related outcomes in numerous studies. The aim was to test its prospective validity at 4-year follow-up. DESIGN Prospective cohort study. SETTING General population sample of young Swiss men. PARTICIPANTS A total of 4594 Swiss young men (median age = 21, 25th - 75th quartiles = 20.5 - 21.5) completed baseline questionnaires; among those, 4214 (91.7%) were successfully followed-up 4 years later. MEASUREMENTS Alcohol reward value parameters (i.e. intensity, the planned consumption when drinks are free; breakpoint, the price at which consumption would be suppressed; Omax , the maximum alcohol expenditure; Pmax , the price associated with Omax ; and elasticity, the relative change in alcohol consumption as a function of the relative change in price) were derived from the APT at baseline and used to predict self-reported weekly drinking amount, monthly binge drinking, alcohol-related consequences and DSM-5 alcohol use disorder criteria. FINDINGS Regression analyses, adjusting for the baseline alcohol measure, age, linguistic region and socio-economic indicators showed that intensity, breakpoint, Omax and elasticity significantly predicted all tested outcomes in the expected direction (e.g. standardized incidence rate ratio [95% confidence interval] = 1.11 [1.07-1.15], 1.07 [1.03-1.10], 1.08 [1.04-1.11], and 0.92 [0.89-0.95], respectively, for weekly drinking amount, all P < 0.001). Pmax did not significantly predict any outcomes. Non-adjusted correlations, baseline adjusted regression and ancillary analyses using (1) latent alcohol variables, (2) multiple imputation for missing data and (3) replications in training and testing subsamples to evaluate predictive accuracy provided consistent findings. CONCLUSIONS The alcohol purchase task demand curve measures of alcohol reward value are useful in characterizing alcohol-related risk in young men and have long-term predictive utility.

Abstract
IMPORTANCE Heavy drinking among young adults is a major public health concern. Brief motivational interventions in the emergency department have shown promising but inconsistent results. OBJECTIVE To test whether young adults receiving a newly developed brief motivational intervention reduce their number of heavy drinking days and alcohol-related problems over 1 year compared with participants receiving brief advice. DESIGN, SETTING, AND PARTICIPANTS This randomized clinical trial was conducted at an emergency department of a tertiary care university hospital in Lausanne, Switzerland. Recruitment ran from December 2016 to August 2019. Follow-up was conducted after 1, 3, 6, and 12 months. All adults aged 18 to 35 years presenting for any cause and presenting with alcohol intoxication were eligible (N = 2108); 1764 were excluded or refused participation. Follow-up rate was 79% at 12 months and 89% of participants provided follow-up data at least once and were included in the primary analyses. Statistical analysis was performed from September 2020 to January 2021. INTERVENTIONS The novel intervention was based on motivational interviewing and comprised in-person discussion in the emergency department and up to 3 booster telephone calls. The control group received brief advice. MAIN OUTCOMES AND MEASURES Primary outcomes were the number of heavy drinking days (at least 60 g of ethanol) over the previous month and the total score on the Short Inventory of Problems (0-45, higher scores indicating more problems) over the previous 3 months. Hypotheses tested were formulated before data collection. RESULTS There were 344 young adults included (median [IQR] age: 23 [20-28] years; 84 women [24.4%]). Among the 306 participants providing at least 1 follow-up point, a statistically significant time × group interaction was observed (β = -0.03; 95% CI, -0.05 to 0.00; P = .02), and simple slopes indicated an increase of heavy drinking days over time in the control (β = 0.04; 95% CI, 0.02 to 0.05; P < .001) but not in the intervention group (β = 0.01; 95% CI, -0.01 to 0.03; P = .24). There was no effect on the Short Inventory of Problems score (β = -0.01; 95% CI, -0.03 to 0.02; P = .71). CONCLUSIONS AND RELEVANCE This randomized clinical trial found that a brief motivational intervention implemented in the emergency department provided beneficial effects on heavy drinking, which accounts for a substantial portion of mortality and disease burden among young adults.

Abstract
The association between alcohol use and sensation seeking is well known. Less is known about whether longitudinal changes in alcohol use are associated with changes in sensation seeking and in which direction influence might flow. 5125 men aged 20.0 years old at baseline and 25.4 years old at follow-up responded to the Brief Sensation Seeking Questionnaire, which measures four subscales of experience seeking, boredom susceptibility, thrill- and adventure-seeking, and disinhibition. Alcohol use was measured using volume (drinks per week) and binge drinking (about 60 g or more per occasion). Associations were calculated using cross-lagged panel models and two-wave latent change score models. Correlations between the latent change scores for alcohol use and the sensation-seeking subscales were all positive, being largest for disinhibition (r > 0.3) and much smaller (r ~ 0.1) for the others. Disinhibition was the dominant effect over the entire sensation-seeking scale. Cross-lagged paths were (except for thrill- and adventure-seeking) bidirectional and mostly higher from alcohol use to sensation seeking (e.g., pathvolume-disinhibition = 0.136, and pathdisinhibition-volume = 0.072). Again, effects were highest for disinhibition. Given the bidirectional links between sensation seeking and alcohol use, preventive efforts aiming to achieve stable positive changes in alcohol use and personality should target both simultaneously and focus on disinhibition.

Abstract
BACKGROUND Both human immunodeficiency virus (HIV) infection and alcohol use predispose to autonomic/sensory neuropathy, imbalance symptoms, and cognitive impairment-conditions associated with a greater risk of falls-yet it is unclear how to identify people with HIV (PWH) whose drinking is associated with falls. Research on alcohol and falls using the same instruments in different countries could help to specify the level of alcohol use associated with fall risk. We examined whether a consumption-based measure (the Alcohol Use Disorders Identification Test-Consumption [AUDIT-C]) and/or a symptom-based measure (DSM-5 criteria for alcohol use disorder [AUD]) are associated with sustaining a fall among PWH in St Petersburg, Russia and Boston, Massachusetts in the United States. METHODS Separate multivariate logistic regressions were used for each cohort to examine cross-sectional associations for each alcohol measure predicting fall. Potential confounders included physical functioning, depressive symptoms, and other substance use (measured with the Addiction Severity Index). RESULTS A fall was reported by 35% (87/251) of the sample in Boston and 12% (46/400) in St Petersburg. Each additional AUD criterion-but not higher AUDIT-C score-was significantly associated with a fall in both Boston (odds ratio [OR] = 1.10; 95% confidence interval [CI] 1.02, 1.18) and St Petersburg (adjusted OR AOR = 1.10; 95% CI 1.02, 1.18). Heavy alcohol use (>6 drinks/occasion, any vs. none) was associated with more than twice the odds of a fall (AOR = 2.24; 95% CI 1.21, 4.13) in Boston. CONCLUSIONS These findings suggest that while fall risk may vary by setting and population, heavy alcohol use and AUD symptom severity are potential targets for interventions to prevent falls. Studies in diverse global settings advance our understanding of the relationship between alcohol and falls in PWH.

Abstract
Screening and brief interventions are among the evidence-based recommended practices to reduce the negative impact of substance use on the population. The digitization of these interventions makes it possible to disseminate them widely and to circumvent some of the barriers to the implementation of face-to-face interventions. Current evidence shows that electronic screening and brief interventions are effective in reducing alcohol and tobacco consumption. For other substances and for gambling, current evidence is more limited but promising and additional research is needed. These interventions can represent an alternative to face-to-face interventions.

Abstract
Addiction medicine is influenced by societal changes and the environment has an impact on addictive behaviors and how they are experienced. The COVID-19 pandemic has had an impact on addictive behaviors, some of which could be favorable, and others highlight vulnerabilities to be considered by clinicians. Recent legislative changes open possibilities to limit the negative impact of electronic lotteries. In a context favorable to a better acceptance of people of LGBTQIA+ diversity, research and training in addiction medicine also have a role to play. In view of advances in understanding the harmful effects of alcohol, it is necessary to adapt the perception of the risk, in order not to provoke the incomprehension in the population.

Abstract
BACKGROUND Substance-induced consciousness alterations (CA) have mainly been studied among users of psychedelics but not among people using street drugs. AIMS Explore occurrences of three different types of substance-induced CA [ego dissolution (ED), visual pseudo-hallucinations (VPH), anxiety/paranoia (A/P)] and their perceived influences on life, together with their associations with substance use and personality correlates in a general population sample of 25-year-old men. METHODS 2,796 young Swiss men lifetime substance users completed a self-report questionnaire including history of use (never, former, and current) of different substances categories (psychedelics, cocaine, psychostimulants, ecstasy, MDMA, and other drugs), substance-induced ego dissolution (ED), visual pseudo-hallucinations (VPH) and anxiety/paranoia (A/P), the influence of these CA experiences on life, and personality traits (sensation seeking, sociability, anxiety-neuroticism, and aggression-hostility). RESULTS 32.2% reported at least one CA (i.e., ED, VPH or A/P), with 20.5% reporting ED, 16.7% VPH, and 14.6% A/P. Former and current use of psychedelics and ketamine was significantly associated with occurrences of all three types of CAs and with a positive influence of CA on life. Associations between the former and current use of other substances and the different types of CA were less consistent, and perceived influences on life were not statistically significant. Sociability was negatively associated with occurrences of all three types of CA. Positive associations were found between anxiety-neuroticism and ED and A/P, between aggression-hostility and A/P, and between sensation seeking and ED and VPH. CONCLUSION This study supports the potential for psychedelics to induce CAs perceived as beneficial to life among people using street drugs, possibly reflecting the mechanism underlying the therapeutic potential of psychedelics.

Abstract
AIMS OF THE STUDY In Switzerland, there has been a boom in the market for cannabidiol (CBD) products in recent years. However, little is known on the prevalence, modes of administration and motives for use of CBD products. The aim of the present study was to fill this gap using recent (2019) data from the Cohort Study on Substance Use Risk Factors (C-SURF). METHODS Between April and December 2019, an unselected sample of 5233 Swiss young men from the French- and German-speaking regions (mean age 28.2 years, standard deviation 1.3) completed a self-report questionnaire covering measures of use of CBD products, modes of administration and motives to use of CBD, tetrahydrocannabinol (THC) and cigarettes. Descriptive statistics were used to estimate prevalence of self-reported use, modes of administration and motives to use CBD, whereas logistic regression models were used to test the associations of linguistic region, THC and tobacco use with use of CBD. RESULTS Lifetime and 12-month prevalence of self-reported use of CBD were 32.4% and 18.5%, respectively. Among past 12-month CBD users, 79.4% used CBD once a month or less often, whereas 20.6% used it more than once a month. The most often reported modes of administration of CBD were in association with tobacco: flowers mixed with tobacco (67.5%), and CBD cigarettes with tobacco (37.1%), while 18.6% used flowers without tobacco. The three most reported reasons for using CBD were: out of curiosity (74.0%), to feel the effects of THC (38.1%) and for well-being and health (37.5%). In multivariable models, CBD use was associated with use of THC (odds ratio [OR] 9.85, 95% confidence interval [CI] 8.28-11.73), cigarettes (OR 2.74, 95% CI 2.28-3.29) or e-cigarettes (OR 1.5795% CI 1.27-1.95), as well as for the linguistic region (French-speaking vs German-speaking region OR 1.3895% CI 1.15-1.65). CONCLUSIONS Self-reported use of CBD is common among young Swiss men: about one third used CBD in their life and about one in five in the previous 12 months. However, the vast majority of CBD users used it infrequently and out of curiosity. CBD use was particularly prevalent among users of THC and cigarette smokers. CBD was most often used in combination with tobacco, thus exposing users to risks associated with smoking tobacco products.

Abstract
BACKGROUND AND AIMS Given the widespread use of cannabis, and the concomitant risks associated with the drug, there is a need to increase the availability of interventions designed to reduce risky cannabis use. One promising intervention in the addictions employs personalized normative feedback to motivate change. METHODS A two-arm randomized controlled trial (RCT) was conducted in which participants who used cannabis in a risky fashion were randomly assigned to one of two groups - those who received an online personalized feedback report in addition to educational materials about risky cannabis use and those who just received the online educational materials. Follow-up assessment occurred at three- and six-months post-randomization. Outcome variables included: number of days cannabis was used in the past 30, risky cannabis use (ASSIST score of four or more), and participant estimates of the proportion of cannabis users among those of the same age and gender. RESULTS A total of 744 participants with risky cannabis use were recruited for the trial using online advertisements. There were no significant differences between intervention and educational materials only groups at three- and six-month follow-ups for the outcome variables, number of days used cannabis in the last 30 (p = 0.927) and proportion of participants engaging in risky cannabis use (p = 0.557). At three and six month follow-ups, participants who received the feedback intervention were more likely than those in the educational materials group to estimate that a larger proportion of people their age and gender did not use cannabis in the last year (p = 0.028). DISCUSSION AND CONCLUSION While there was some evidence that the personalized feedback intervention modified normative perceptions about cannabis use, there did not appear to be support for the prediction that the intervention reduced cannabis consumption.

Abstract
Background: The COVID-19 pandemic and its countermeasures may have had a significant impact on the psychological well-being of specific population subgroups. The present study investigated whether sexual minority men (defined here as attracted partly or exclusively to men) from an ongoing cohort study of young Swiss men experienced different psychological impacts, levels of substance use and addictive behaviors, and to which degree pre-existing vulnerabilities and participants experiences during the crisis might explain these differences. Methods: An ongoing cohort sample based on the general population of young Swiss men (mean age = 29.07 years; SD = 1.27) was assessed before and during the COVID-19 crisis for depression, stress, sleep quality, substance use and addictive behaviors. Additionally, during the crisis, we assessed its impact in form of fear, isolation and traumatic experiences. Potential associations between these outcomes and sexual orientation (sexual minority vs. heterosexual) were tested using linear regression models. It was additionally estimated to which degree these associations were attenuated if adjusted for differences in mental health, personality and socioeconomic status before the crisis, as well as the experience of the COVID-19 crisis (infection with the virus and changes to work situation). Results: Compared to heterosexual men, sexual minority men showed higher levels of psychological trauma (b = 0.37 [0.25, 0.49]), fear (b = 0.18 [0.06, 0.30]) and isolation (b = 0.32 [0.20, 0.44]) due to the COVID-19 pandemic as well as higher levels of depression (b = 0.31 [0.20, 0.41]) and lower sleep quality (b = −0.13 [−0.24, −0.02]) during the crisis. These differences were to a large degree explained by higher pre-crisis levels of mental health problems and the personality dimension of neuroticism-anxiety. Sexual minority men showed higher overall levels of substance use and addictive behaviors, but these differences were already present before the crisis. Conclusion: The COVID-19 crisis may have worsened pre-existing vulnerabilities in sexual minority men, leading to its greater psychological impact on them than on heterosexual men. Reducing minority stress due to sexual orientation may help not only to improve mental health among important proportions of the population but also to reduce their vulnerability to crises. Services offering psychological support to sexual minorities may need to be reinforced during crises.

Abstract
BACKGROUND AND AIMS There are concerns about the potential impact of the coronavirus disease (COVID-19) pandemic on substance use (SU) and other reinforcing behaviours (ORB). This paper investigates changes in SU and ORB among young men during the COVID-19 crisis (i.e. March-June 2020). METHODS Before and during the COVID-19 crisis, 2,344 young Swiss men completed questionnaires covering SU (i.e. alcohol, cigarettes, illegal cannabis), ORB (i.e. gaming, watching TV series, internet pornography) and sociodemographic and work-related characteristics (i.e. deterioration in the work situation, change in working hours, change in working hours from home, healthcare workers' and other professionals' contacts with potentially infected people, linguistic region, call up to military or civil protection unit, living situation, age). RESULTS Latent-change score models showed significant decreases of 17% for drinking volume and frequency of heavy episodic drinking, and a significant increase of 75% for time spent gaming and watching TV series. Subgroups showed greater relative increases. French-speaking participants, those who experienced a deterioration in their work situation and healthcare workers in contact with potentially infected people reported increased cigarette use. Those without children increased gaming, whereas those who worked fewer hours, experienced a deterioration in their work situation or were French-speaking did more gaming and watched more TV series. Those who lived alone or were German-speaking watched more internet pornography. CONCLUSION During the COVID-19 crisis, young Swiss men drank less alcohol and spent more time gaming and watching TV series. Changes in SU and ORB were not homogenous in the young Swiss men population.

Abstract
AIMS The COVID-19 pandemic caused many disturbances to daily life worldwide and may also have significantly affected people's psychological well-being. The present study aimed to describe the psychological impact of the crisis on our sample of young Swiss men and to examine differences due to their linguistic region, experiencing COVID-19 symptoms and living arrangements. METHODS Based on an ongoing cohort study, we assessed a general-population sample of young Swiss men (n = 2345; average 29 years old) shortly before (from April 2019) and early on during the COVID-19 crisis (between 13 May and 8 June 2020). This was a unique opportunity to estimate the crisis' psychological impact in the form of depression, perceived stress and sleep quality (assessed before and during COVID-19), and any crisis-induced fears, isolation or psychological trauma. Associations of psychological impact with living arrangements, experiencing COVID-19 symptoms and linguistic region (German-speaking vs French-speaking) were investigated using linear regression models. FINDINGS By the time participants responded to our questionnaire, less than 1% had been tested positive for COVID-19, 2.6% had been tested negative and 14.7% had had some COVID-19 symptoms but had not been tested. About 8.2% of the sample reported at least some symptoms of psychological trauma (≥24 points on the Impact of Event Scale). On average, participants reported higher levels of fear for others (43.6% at least moderate) and economic fear (12.7% at least moderate) than fear for themselves (5.8% at least moderate). Those living alone and those who reported having COVID-19 symptoms themselves, or knowing someone with symptoms, reported higher overall psychological impact in the form of depression, perceived stress, sleep quality, psychological trauma, fear and isolation. Associations with linguistic region varied by outcome, with higher levels of depression and fear in French-speaking regions and higher levels of perceived stress and isolation in German-speaking regions. INTERPRETATION The crisis had a considerable impact on the psychological well-being of our sample of young Swiss men, and some groups were more affected than others: those living alone and those who had shown COVID-19 symptoms themselves or had known someone with symptoms may have felt a greater psychological impact from the crisis. Supporting those at a higher risk of psychological consequences in such crises, whether through structural measures or via individual support, should be an important aspect of crisis management and could help reduce the overall impact of the current pandemic on Switzerland's population.

Abstract
AIMS The present study aimed to investigate whether the psychological impact of the COVID-19 crisis varied with regards to young Swiss men's pre-crisis level of education and socioeconomic status and to changes in their work situation due to it. METHODS A cohort of 2345 young Swiss men (from 21 out of 26 Swiss cantons; mean age = 29) completed survey-based assessments shortly before (April 2019 to February 2020) and early on during the COVID-19 crisis (May to June 2020). Outcomes measured were psychological outcomes before and during the COVID-19 crisis (depression, perceived stress and sleep quality), and the fear, isolation and psychological trauma induced by it. We investigated associations between these outcomes and their predictors: pre-crisis socioeconomic status (relative financial status, difficulty paying bills, level of education), changes in work situation during the crisis (job loss, partial unemployment, working from home, change in workload) and working in contact with potentially infected people, both inside and outside the healthcare sector. For outcomes measured before and during the crisis, the analyses were adjusted for their pre-crisis levels. RESULTS About 21% of participants changed their employment status (job loss, partial unemployment or lost money if self-employed) and more than 40% worked predominantly from home during the COVID-19 crisis. Participants with a lower relative socioeconomic status already before the crisis experienced a higher psychological impact due to the COVID-19 crisis, compared to participants with an average socioeconomic status (major depression (b = 0.12 [0.03, 0.22]), perceived stress (b = 0.15 [0.05, 0.25]), psychological trauma (b = 0.15 [0.04, 0.26]), fear (b = 0.20 [0.10, 0.30]) and isolation (b = 0.19 [0.08, 0.29])). A higher impact was also felt by participants who lost their job due to the COVID-19 crisis, the partially unemployed, those with an increased workload or those who worked mainly from home (e.g. depression b = 0.25 [0.16, 0.34] for those working 90%+ at home, compared to those not working at home). CONCLUSIONS Even in a country like Switzerland, with relatively high social security benefits and universal healthcare, the COVID-19 crisis had a considerable psychological impact, especially among those with a lower socioeconomic status and those who experienced deteriorations in their work situation due to the COVID-19 crisis. Supporting these populations during the crisis may help to prevent an amplification of inequalities in mental health and social status. Such support could help to lower the overall impact of the crisis on the mental well-being of Switzerland's population.

Abstract
BACKGROUND Information about correlates of cannabis vaping in Europe is scarce. METHODS In a cohort of 1613 Swiss young males currently using cannabis, we used logistic regression, adjusting for age, linguistic region and education to assess the association between sensation seeking, substance use and sociodemographic variables with cannabis vaping. RESULTS Mean age was 25.38 years, 60.4% had post-secondary education and 57.3% lived in French-speaking cantons; 26.3% met criteria for nicotine dependence, 16.0% met criteria for alcohol use disorder and 34.9% used illicit drugs other than cannabis; 27.4% used cannabis at least twice a week and 27.8% met criteria for cannabis use disorder (CUD). Ninety-four participants (5.8%) reported cannabis vaping (of them 87.4% reported infrequent cannabis vaping). In the adjusted analysis, using joints with no tobacco {adjusted odds ratio (aOR) [95% confidence interval (CI)] = 1.45 (1.02-1.76)}, water pipe with [aOR (95% CI) = 1.70 (1.29-2.24)] and without tobacco [aOR (95% CI) = 2.15 (1.60-2.87)], cannabis mixed with food [aOR (95% CI) = 1.61 (1.29-2.02)], using cannabis >2 times a week [aOR (95% CI) = 3.73 (2.40-5.81)], meeting criteria for CUD [aOR (95% CI) = 4.19 (2.70-6.50)], using illicit drugs other than cannabis [aOR (95% CI) = 1.88 (1.23-2.87)], weekly number of alcohol drinks [aOR (95% CI) = 1.01 (1.00-1.03)] and living in the German-speaking area of Switzerland [aOR (95% CI) = 2.70 (1.71-4.25)] were associated with higher odds of cannabis vaping; post-secondary schooling [aOR (95% CI) = 0.37 (0.16-0.86)] and vocational training [aOR (95% CI) = 0.41 (0.17-0.99)] (as opposed to primary schooling) were associated with lower odds of cannabis vaping. CONCLUSION Cannabis vaping might be a marker of riskier behaviours among cannabis users.

Abstract
Introduction The COVID-19 pandemic impacted daily life worldwide. It may also have had a psychological impact, especially on those with less resources already before the crisis and those who reported substantial changes to their work situation. Objectives To investigate whether socioeconomic status before the crisis and changes in work situation during the crisis (unemployment, home-office) are associated with psychological impact in a cohort of young Swiss men. Methods A total of 2345 young Swiss men (mean age = 29) completed assessments shortly before (April 2019 to February 2020) and early during the COVID-19 crisis (May to June 2020). Assessments covered psychological outcomes assessed before and during COVID-19 crisis (depression, perceived stress and sleep quality), and assessed during the crisis (fear, isolation and COVID-19 psychological trauma), socioeconomic status (relative financial status and difficulty to pay bills) before the crisis and changes in work situation (unemployment, home-office). Results About a fifth of the sample were in partial unemployment or lost their job during COVID-19 crisis. Those in partial or full unemployment, those mostly working from home and those with a lower socioeconomic status already prior to the crisis showed overall higher levels of depression, stress, psychological trauma, fear and isolation. Conclusions Even in a country with high social security such as Switzerland, the COVID-19 crisis had a higher psychological impact on those who were already disadvantaged before the crisis or experienced deteriorations in their work situation. Supporting disadvantaged subpopulations during the crisis may help to prevent an amplification of pre-existing inequalities. Disclosure No significant relationships.

Abstract
BACKGROUND Unhealthy alcohol use among young adults is a major public health concern. Brief motivational interventions for young adults in the Emergency Department (ED) have shown promising but inconsistent results. METHODS Based on the literature on brief intervention and motivational interviewing efficacy and active ingredients, we developed a new motivational intervention model for young adults admitted in the ED with alcohol intoxication. Using an iterative qualitative design, we first pre-tested this model by conducting 4 experimental sessions and 8 related semi-structured interviews to evaluate clinicians' and patients' perceptions of the intervention's acceptability and feasibility. We then conducted a consultation meeting with 9 international experts using a nominal group technique. The intervention model was adjusted and finally re-tested by conducting 6 new experimental sessions and 12 related semi-structured interviews. At each round, data collected were analyzed and discussed, and the intervention model updated accordingly. RESULTS Based on the literature, we found 6 axes for developing a new model: High level of relational factors (e.g. empathy, alliance, avoidance of confrontation); Personalized feedback; Enhance discrepancy; Evoke change talk while softening sustain talk, strengthen ability and commitment to change; Completion of a change plan; Devote more time: longer sessions and follow-up options (face-to-face, telephone, or electronic boosters; referral to treatment). A qualitative analysis of the semi-structured interviews gave important insights regarding acceptability and feasibility of the model. Adjustments were made around which information to provide and how, as well as on how to deepen discussion about change with patients having low levels of self-exploration. The experts' consultation addressed numerous points, such as information and advice giving, and booster interventions. DISCUSSION This iterative, multi-component design resulted in the development of an intervention model embedded in recent research findings and theory advances, as well as feasible in a complex environment. The next step is a randomized controlled trial testing the efficacy of this model.

Abstract
BACKGROUND Information technology can be used to advance addiction science and clinical practice. MAIN BODY This special issue, "Information technology (IT) interventions to advance treatment for opioid and other addictions" presents studies that expand our understanding of IT intervention efficacy, patients' perspectives, and how IT can be used to improve substance use health care and research. This editorial introduces the topics addressed in the special issue and focuses on some of the challenges that the field is currently facing, such as attrition and treatment retention, transferability of intervention paradigms, and the challenge to keep pace with rapidly changing technologies. CONCLUSIONS Increasing treatment reach is particularly crucial in the addiction field. IT empowers researchers and clinicians to reach large portions of the population who might not otherwise access standard treatment modalities, because of geographical limitations, logistical constraints, stigma, or other reasons. The use of information technology may help reduce the substance use treatment gap and contribute to public health efforts to diminish the impact of substance use and other addictive behaviors on population health.

Abstract
Whereas excessive alcohol consumption increases liver disease incidence and mortality, evidence on the risk associated with specific drinking patterns is emerging. We assessed the impact of binge drinking on mortality and liver disease in the Swiss HIV Cohort Study. All participants with follow-up between 2013 and 2020 were categorized into one of four drinking pattern groups: “abstinence”, “non-hazardous drinking”, “hazardous but not binge drinking” (Alcohol Use Disorder Identification Test Consumption [AUDIT-C] score ≥ 3 in women and ≥4 in men), and “binge drinking” (≥6 drinks/occasion more than monthly). We estimated adjusted incidence rate ratios (aIRR) for all-cause mortality, liver-related mortality and liver-related events using multivariable quasi-Poisson regression. Among 11,849 individuals (median follow-up 6.8 years), 470 died (incidence rate 7.1/1000 person-years, 95% confidence interval [CI] 6.5–7.8), 37 experienced a liver-related death (0.6/1000, 0.4–0.8), and 239 liver-related events occurred (3.7/1000, 3.2–4.2). Compared to individuals with non-hazardous drinking, those reporting binge drinking were more likely to die (all-cause mortality: aIRR 1.9, 95% CI 1.3–2.7; liver-related mortality: 3.6, 0.9–13.9) and to experience a liver-related event (3.8, 2.4–5.8). We observed no difference in outcomes between participants reporting non-hazardous and hazardous without binge drinking. These findings highlight the importance of assessing drinking patterns in clinical routine.

Abstract
Although young men or young adults with mental health disorders are at higher risk to engage in problematic drinking, they typically evince stronger associations between protective behavioral strategies (PBS) and fewer alcohol outcomes. This study aimed to contribute to this line of research by examining the moderating effect of depression, bipolar spectrum disorder, borderline personality disorder and social anxiety disorder on the association between PBS and alcohol outcomes. Participants (N = 4,960; mean age = 25.43) were young men participating in the Cohort Study on Substance Use Risk Factors. Measures of PBS use, typical drinks per week, alcohol-related consequences, depression, bipolar spectrum disorder, borderline personality disorder and social anxiety disorder were used from the second follow-up assessment. Main results indicated that the negative association between PBS and alcohol use was stronger in participants with borderline personality disorder than among those without this disorder. Unexpectedly, in participants with depression, PBS were not significantly associated with alcohol use, whereas they were related to fewer drinks among those without the disorder. Similarly, in participants with bipolar spectrum disorder, the association between PBS and alcohol-related consequences was not significant, whereas PBS were associated with fewer consequences in those without the disorder. Finally, findings indicated that social anxiety disorder did not significantly moderate the associations between PBS and alcohol outcomes. If replicated by future research, these findings imply that PBS-intervention may not equally impact young adults with diverse mental health disorders.

Abstract
AIMS To estimate age-specific changes in hospital admissions for alcohol intoxication following two consecutive restrictions on off-premises alcohol sales introduced in the canton of Vaud, Switzerland. DESIGN Primary analyses used interrupted autoregressive integrated moving average (ARIMA) time-series analyses (repeated cross-sectional), with Lausanne and Vaud as experimental sites and the rest of Switzerland as the control. Secondary analyses used, for example, a different control site (other French-speaking cantons only) or a different statistical model. SETTING Switzerland between 2010 and 2016. PARTICIPANTS In-patients (i.e. patients assigned a bed overnight) hospitalized between 8 p.m. and 6 a.m. (n = 1 261 564), as documented in the Swiss Hospital Statistics. INTERVENTIONS Ban 1, only effective in the canton's capital, Lausanne, prohibited off-premises sales of all alcoholic beverages after 8 p.m. on Fridays and Saturdays from September 2013 to June 2015. In July 2015, Ban 2 replaced this, covered the whole canton and affected off-premises sales of beer and spirits (but not wine) after 9 p.m. (8 p.m. in Lausanne) every night of the week. MEASUREMENTS Proportions of monthly hospital admissions for alcohol intoxication (ICD-10 diagnoses F10.0/F10.1, T51.0) per 1000 monthly overall admissions. FINDINGS Proportions of overall hospitalizations for alcohol intoxication declined after both bans in Lausanne [ωBan1 = -0.017, 95% confidence interval (CI) = -0.025, -0.008; ωBan2 = -0.021, 95% CI = -0.030, -0.013] but only after Ban 2 in the remainder of the canton of Vaud (ωBan2 = -0.008, 95% CI = -0.014, -0.002). Estimated changes in % were largest among 16-19-year-olds. However, as admission rates for alcohol intoxication were more frequent in adulthood than adolescence, the estimated change in number of cases was also relevant to public health among 20-69-year-olds. Secondary analyses supported the findings of the primary analyses. CONCLUSION Even partial restrictions of off-premises sales of alcohol in Switzerland (only 2 days per week or only for beer and spirits) appeared to reduce hospital admissions for alcohol intoxication across a wide age range (ages 16-69 years).

Abstract
AIMS The efficacy of screening and brief intervention for lower-risk drug use is unknown. This pilot study tested the efficacy of two brief interventions (BIs) for drug use compared to no BI in primary care patients with lower-risk drug use identified by screening. METHODS We randomly assigned participants identified by screening with Alcohol Smoking and Substance Involvement Screening Test (ASSIST) drug specific scores of 2 or 3 to: no BI, a brief negotiated interview (BNI), or an adaptation of motivational interviewing (MOTIV). Primary outcome was number of days use of main drug in the past 30 as determined by validated calendar method at 6 months. Analyses were performed using negative binomial regression adjusted for baseline use and main drug. RESULTS Of 142 eligible adults, 61(43 %) consented and were randomized. Participant characteristics were: mean age 41; 54 % male; 77 % black. Main drug was cannabis 70 %, cocaine 15 %, prescription opioid 10 %; 7% reported injection drug use and mean days use of main drug (of 30) was 3.4. At 6 months, 93 % completed follow-up and adjusted mean days use of main drug were 6.4 (no BI) vs 2.1 (BNI) (incidence rate ratio, IRR 0.33[0.15-0.74]) and 2.3 (MOTIV) (IRR 0.36[0.15-0.85]). CONCLUSIONS BI appears to have efficacy for preventing an increase in drug use in primary care patients with lower-risk use identified by screening. These findings raise the potential that less severe patterns of drug use in primary care may be uniquely amenable to brief intervention and warrant replication.

Abstract
BACKGROUND Unhealthy alcohol use is a leading cause of morbidity and mortality among young people, including university students. Delivering secondary prevention interventions against unhealthy alcohol use is challenging. Information technology has the potential to reach large parts of the general population. The present study is proposed to test a proactive secondary prevention smartphone-based intervention against unhealthy alcohol use. METHODS This is a parallel-group, randomized controlled trial (1:1 allocation ratio) among 1696 university students with unhealthy alcohol use, identified by screening and followed up at 3, 6, and 12 months. Participants will be randomized to receive access to a smartphone-based intervention or to a no intervention control condition. The primary outcome will be self-reported volume of alcohol drunk over the past 30 days, reported as the mean number of standard drinks per week over the past 30 days, measured at 6 months. Secondary outcomes will be number of heavy drinking days over the past 30 days, at 6 months. Additional outcomes will be maximum number of drinks on any day over the past 30 days, alcohol-related consequences (measured using the Short Inventory of Problems (SIP-2R), and academic performance. DISCUSSION The aim of this trial is to close the evidence gap on the efficacy of smartphone-based secondary prevention interventions. If proven effective, smartphone-based interventions have the potential to reach a large portion of the population, completing what is available on the Internet. TRIAL REGISTRATION ISRCTN, 10007691. Registered on 2 December 2019. Recruitment will start in April 2020.

Abstract
AIMS An updated Cochrane systematic review assessed effectiveness of screening and brief intervention to reduce hazardous or harmful alcohol consumption in general practice or emergency care settings. This paper summarises the implications of the review for clinicians. METHODS Cochrane methods were followed. Reporting accords with PRISMA guidance. We searched multiple resources to September 2017, seeking randomised controlled trials of brief interventions to reduce hazardous or harmful alcohol consumption in people attending general practice, emergency care or other primary care settings for reasons other than alcohol treatment. Brief intervention was defined as a conversation comprising five or fewer sessions of brief advice or brief lifestyle counselling and a total duration of less than 60 min. Our primary outcome was alcohol consumption, measured as or convertible to grams per week. We conducted meta-analyses to assess change in consumption, and subgroup analyses to explore the impact of participant and intervention characteristics. RESULTS We included 69 studies, of which 42 were added for this update. Most studies (88%) compared brief intervention to control. The primary meta-analysis included 34 studies and provided moderate-quality evidence that brief intervention reduced consumption compared to control after one year (mean difference -20 g/wk, 95% confidence interval -28 to -12). Subgroup analysis showed a similar effect for men and women. CONCLUSIONS Brief interventions can reduce harmful and hazardous alcohol consumption in men and women. Short, advice-based interventions may be as effective as extended, counselling-based interventions for patients with harmful levels of alcohol use who are presenting for the first time in a primary care setting.

Abstract
BACKGROUND AND AIMS Behavioral addictions (BAs) and substance use disorders (SUDs) tend to co-occur; both are associated with mental health problems (MHPs). This study aimed to estimate the proportion of variance in the severity of MHPs explained by BAs and SUDs, individually and shared between addictions. METHODS A sample of 5,516 young Swiss men (mean = 25.47 years old; SD = 1.26) completed a self-reporting questionnaire assessing alcohol, cannabis, and tobacco use disorders, illicit drug use other than cannabis, six BAs (Internet, gaming, smartphone, Internet sex, gambling, and work) and four MHPs (major depression, attention-deficit hyperactivity disorder, social anxiety disorder, and borderline personality disorder). Commonality analysis was used to decompose the variance in the severity of MHPs explained (R2) by BAs and SUDs into independent commonality coefficients. These were calculated for unique BA and SUD contributions and for all types of shared contributions. RESULTS BAs and SUDs explained between a fifth and a quarter of the variance in severity of MHPs, but individual addictions explained only about half of this explained variance uniquely; the other half was shared between addictions. A greater proportion of variance was explained uniquely or shared within BAs compared to SUDs, especially for social anxiety disorder. CONCLUSIONS The interactions of a broad range of addictions should be considered when investigating their associations with MHPs. BAs explain a larger part of the variance in MHPs than do SUDs and therefore play an important role in their interaction with MHPs.

Abstract
Squamous cell carcinoma (SCC) of the head and neck is the sixth most common cancer worldwide. It is preceded by early asymptomatic lesions which, if identified early enough and removed, would prevent malignant transformation or avoid delaying diagnosis to advanced stages. Our aim was to evaluate the feasibility of a screening programme for SCC of the head and neck in a group of high-risk patients, and to investigate their addiction profile. Patients admitted to an inpatient alcohol addiction centre (n=101) were prospectively enrolled and asked to fill in a questionnaire about their use of tobacco and alcohol, and the presence of warning symptoms for SCC of the head and neck from 23 June 2014 to 21 January2016. Participants in the study had a physical examination by an alcohol addiction physician followed by a full examination of the head and neck by an otorhinolaryngologist to rule out premalignant or malignant lesions of the upper aerodigestive tract. Of the 101 patients, 62 (60%) had at least one warning symptom. Alcohol addiction physicians identified leukoplakia in six (6%) and erythroplakia in two. No pre-malignant or malignant lesions were confirmed on examination by the otolaryngologist. We were unable to draw conclusions about the cost-effectiveness or the yield of the screening programme. Despite our negative findings, we may need further investigation to clarify the relevance of such a programme on health-related outcome given the high compliance rate and minimal delay that was achieved by taking advantage of an in-patient alcohol rehabilitation centre.

Abstract
BACKGROUND How much a randomized controlled trial (RCT) sample is representative of or differs from its source population is a challenging question, with major implications for generalizability of results. It is particularly crucial for freely-available web-based interventions tested in RCTs since they are designed to reach broad populations and could increase health disparities if they fail to reach the more vulnerable individuals. We assessed the representativeness of a sample of participants in a primary/secondary prevention web-based brief intervention RCT in relation to its source population. Then we compared those recruited to those not recruited in the RCT. METHODS There is a mandatory army recruitment process in Switzerland at age 19 for men. Between August 2010 and July 2011, 12,564 men (source population) attended two recruitment centers and were asked to answer a screening questionnaire on alcohol use. Among 11,819 (94.1%) who completed it, 7027 (59.5%) agreed to participate in a longitudinal cohort study with regular assessments. In 2012, these participants were invited to a web-based brief intervention RCT. Participation was not dependent on the presence or quantity of alcohol use. We assessed the representativeness of the RCT sample in relation to the source population and compared participants recruited/not recruited in the RCT with respect to education level and alcohol use. RESULTS The RCT sample differed from the source population: individuals 20 and over were significantly less represented (34.3% vs 37.9%, p = 0.006), as were those with lower education level (58.6% vs 63.0%, p = 0.0009). The prevalence of any alcohol use was higher in the RCT population (92.3% vs 90.6%, p = 0.03) but unhealthy alcohol use was less represented (37.1% vs 43.2%, p < 0.0001). Differences on alcohol use measures and education were similarly found when those recruited in the RCT were compared to those who were not, including in a multivariable model, showing independent associations between less unhealthy alcohol use and higher education and recruitment in the RCT. CONCLUSIONS RCT participants differed from other members of the source population, with those participating in the RCT having higher prevalence of any alcohol use but lower levels of consumption and lower prevalence of indicators of unhealthy alcohol use. Individuals with higher education were overrepresented in the RCT sample. Selection bias may exist at both ends of the drinking spectrum and individuals with some indicators of greater vulnerability were less likely to participate. Results of web-based studies may not adequately generalize to the general population.Trial registration: The trial was registered at current controlled trials: ISRCTN55991918.

Abstract
BACKGROUND Alcohol use disorder (AUD) is known to co-occur with other addictions, as well as with mental health problems. However, the effects of other addictions co-occurring with AUD on mental health problems were rarely studied and not considering them may bias estimates of the association between AUD and mental health problems. This study investigated which role co-occurring addictions play for the cross-sectional associations between self-reported AUD and mental health problems. METHOD Participants were 5516 young Swiss men (73.0% of those that gave written informed consent) who completed a self-report questionnaire. Using short screening questionnaires, we assessed three substance use disorders (alcohol, cannabis and tobacco), seven behavioural addictions (internet, gaming, smartphone, internet sex, gambling, work, exercise) and four mental health problems (major depression, bipolar disorder, attention deficit hyperactivity disorder (ADHD) and social anxiety disorder). Differences in the proportions of mental health problems were tested using logistic regressions between (1) participants with no AUD and AUD, (2) participants with no AUD and AUD alone and (3) participants with no AUD and AUD plus at least one co-occurring addiction. RESULTS Overall, (1) participants with AUD had higher proportions of major depression (Odds ratio (OR [95% confidence interval]) = 3.51 [2.73, 4.52]; ADHD (OR = 3.12 [2.41, 4.03]); bipolar disorder (OR = 4.94 [3.38, 7.21]) and social anxiety (OR = 2.21 [1.79, 2.73])) compared to participants with no AUD. Considering only participants with AUD alone compared to participants with no AUD (2), differences in proportions were no longer significant for major depression (OR = 0.83 [0.42, 1.64]), bipolar disorder (OR = 1.69 [0.67, 4.22]), social anxiety (OR = 1.15 [0.77, 1.73]) and ADHD (OR = 1.65 [1.00, 2.72]) compared to participants with no AUD. In contrast, (3) proportions of mental health problems were considerably higher for participants with AUD plus at least one other addiction when compared to participants with no AUD, with OR's ranging from 2.90 [2.27, 3.70] for social anxiety, 4.03 [3.02, 5.38] for ADHD, 5.29 [4.02, 6.97] for major depression to 6.64 [4.44, 9.94] for bipolar disorder. CONCLUSIONS AUD was associated with all four measured mental health problems. However, these associations were mainly due to the high proportions of these mental health problems in participants with AUD plus at least one co-occurring addiction and only to a lesser degree due to participants with AUD alone (i.e. without any other co-occurring addictions). Hence, estimates of the association between AUD and mental health problems that do not consider other addictions may be biased (i.e. overestimated). These findings imply that considering addictions co-occurring with AUD, including behavioural addictions, is important when investigating associations between AUD and mental health problems, and for the treatment of AUD and co-morbid disorders.

Abstract
BACKGROUND AND AIMS Alcohol-induced blackout (AIB) is a common alcohol-related adverse event occurring during teenage years. Although research provides evidence that AIB predicts acute negative consequences, less is known about the associations of AIB with chronic consequences, such as alcohol dependence (AD). This study estimated the associations between an experience of AIB at age 20 and the incidence, maintenance and severity of AD at age 25 among Swiss men. DESIGN Prospective cohort study with 5.5 years separating baseline and follow-up. SETTING Switzerland. PARTICIPANTS Swiss male drinkers (n = 5469, age 20 at baseline) drawn from the Cohort Study on Substance Use Risk Factors (C-SURF). MEASUREMENTS Self-report questionnaires assessing AIB, AD, alcohol (drinking volume, binge drinking), cigarette and cannabis use, several risk factors (sensation-seeking, family history of problematic alcohol use, age of first alcohol intoxication) and socio-demographic variables. FINDINGS Generalized estimating equation models with and without adjustment for risk factors, including alcohol use and socio-demographics, showed that AIB at age 20 significantly predicted the incidence of AD at age 25 in men without AD at age 20 [odds ratio (OR) = 2.52, 95% confidence interval (CI), unadjusted = 2.04, 3.11, P < 0.001; fully adjusted, OR = 1.47, 95% CI = 1.13, 1.91, P = 0.004], maintenance of AD in men with AD at age 20 (unadjusted, OR = 1.82, 95% CI = 1.12, 2.95, P = 0.015; fully adjusted, OR = 1.66, 95% CI = 1.00, 2.76, P = 0.048] and AD severity [unadjusted incidence rate ratio (IRR) = 1.89, 95% CI = 1.69, 2.11, P < 0.001; fully adjusted, IRR = 1.20, 95% CI = 1.10, 1.31, P < 0.001]. CONCLUSIONS Among Swiss men, alcohol-induced blackout at age 20 predicts the development, maintenance and severity of alcohol dependence at age 25.

Abstract
Background: In primary care, electronic self-administered screening and brief interventions for unhealthy alcohol may overcome some of the implementation barriers of face-to-face intervention. We developed an anonymous electronic self-administered screening brief intervention device for unhealthy alcohol use and assessed its feasibility and acceptability in primary care practice waiting rooms. Two modes of delivery were compared: with or without the presence of a research assistant (RA) to make patients aware of the device's presence and help users. Using the device was optional. Methods: The devices were placed in 10 participating primary care practices waiting rooms for 6 weeks, and were accessible on a voluntary basis. Number of appointments by each practice during the course of the study was recorded. Access to the electronic brief intervention was voluntary among those who screened positive. Screening and brief intervention rates and characteristics of users were compared across the modes of delivery. Results: During the study, there were 7270 appointments and 1511 individuals used the device (20.8%). Mean age of users was 45.3 (19.5), and 57.9% screened positive for unhealthy alcohol use. Of them, 53.8% accessed the brief intervention content. The presence of the RA had a major impact on the device's usage (59.6% vs 17.4% when absent). When the RA was present, participants were less likely to screen positive (49.4% vs 60.7%, P = 0.0003) but more likely to access the intervention (62.7% vs 51.4%, P = 0.009). Results from the satisfaction survey indicated that users found the device easy to use (93.5%), questions useful (89-95%) and 77.2% reported that their friends would be willing to use it. Conclusions: This pilot project indicates that the implementation of an electronic screening and brief intervention device for unhealthy alcohol is feasible and acceptable in primary care practices but that, without human support, its use is rather limited.

Abstract
Background Two randomized controlled trials (RCTs) were conducted to explore the utility of the Mechanical Turk (MTurk) crowdsourcing platform to conduct rapid trials evaluating online interventions for unhealthy alcohol use. Methods Both trials employed a staged recruitment procedure where participants who drank in an unhealthy fashion were identified using a baseline survey and then invited to take part in a 6-month follow-up. Participants in both trials were randomized to receive one of several different online interventions or to a no intervention control condition. In study 1, the online interventions were password protected and only those who accessed the study portal were randomized to condition. In study 2, participants were directed to free-of charge interventions and asked to send a screenshot of the intervention to demonstrate that they had complied. Results Participants reporting unhealthy alcohol use were recruited fairly rapidly. Large numbers of screeners were completed (Study 1: n = 4910; Study 2: n = 5812), found eligible (Study 1: n = 3741; Study 2: n = 4095), and randomized to condition (Study 1: n = 511; Study 2: n = 878). Fair follow-up rates were observed at 6 months for each study (Study 1: 82%; Study 2: 66%). Neither trial was able to clearly demonstrate that providing access to the online interventions lead to increased reductions in alcohol use as compared to the control group. Conclusions While recruitment through a crowdsourcing platform is rapid and relatively low cost, it is possible that the lack of impact of the online websites employed in these trials could be due to the source of participants rather than the lack of efficacy of the interventions. Trial registration ClinicalTrials.gov # NCT02977026 and NCT03060135.

Abstract
The language used has an impact on clinician attitudes and behaviors. In particular, the use of stigmatizing language or language reducing individuals in treatment to a given behavior has a negative impact on clinician attitudes, perception of people, perception of the disorders and treatment options. In addiction medicine, using clear, non-stigmatizing and scientifically appropriate language aims at delivering better care, increases treatment access, improves communication between health care professionals and improves knowledge transfer towards health care system users and their families, health care providers and society. The use of clear, slang-free, people-first language is crucial.

Abstract
Estimating alcohol consumption using biomarkers raises interpretation problems. The biomarkers currently used in clinical settings have limited performances to identify unhealthy alcohol use (e.g. CDT, AST, ALT). New direct biomarkers, ethylglucuronide (EtG) and phosphatydilethanol (PEth) are available and offer better sensitivity and specificity compared to indirect biomarkers. In forensic medicine, EtG and PEth are replacing indirect biomarkers. However, in clinical routine practice these markers are usually not considered. Still, for specific purposes such in pre-liver transplant evaluations, direct markers may help specialists in the decision process.

Abstract
BACKGROUND There is limited evidence of the efficacy of smartphone applications to reduce unhealthy alcohol use. We tested the efficacy of providing access to a smartphone-based brief intervention for unhealthy alcohol use. METHODS We conducted a two parallel-group randomized controlled trial with follow-up at 6 months, among 977 individuals with an Alcohol Use Disorder Identification Test ≥8 and drinking 15 or more drinks/week. Participants were randomized to receive (or not) access to a smartphone application consisting of personalized feedback, risk assessment and self-monitoring. The primary outcome was the mean number of drinks/week. An intention to treat analysis (ITT) and a per protocol analysis (PP) were conducted. RESULTS Mean age of participants was 34.2(9.8), 46% were female. The baseline mean number of drinks per week was 28.9(16.7). Results differed by type of analysis: ITT: all 977 participants were included in the analysis. Follow-up rate was 70.7% (n = 691). There was no significant intervention effect: the Incidence Rate Ratio (IRR) (95%CI) for number of drinks per week was 0.93(0.84; 1.03). PP: 702 participants were included in the analysis. Follow-up rate was 78.1% (n = 548). There was a significant intervention effect: the IRR for number of drinks per week was 0.88(0.78; 0.99). CONCLUSIONS Providing access to a smartphone-based brief intervention had no impact on drinking at 6 months and does not appear to be an effective intervention in reducing drinking. Those who downloaded the app appear to benefit from it, nevertheless downloads were limited and further development of similar apps should focus on increasing use.

Abstract
New drugs available in a click, plethora of games, new regulations on cannabis, addiction medicine has a lot to do ! In 2018, Switzerland recognized a training certificate in addiction medicine, pathological gambling entered into ICD-11 and vaping, first considered with suspicion, found a place in the pharmacopoeia of the fight against tobacco. That's not all, on the alcohol front, we realized that even a small glass can hurt and the medicine of addictions evolved towards models of recovery that aim to improve quality of life with chronic diseases. Finally, the American opioid prescription epidemic is worrying in Switzerland, even if the situation and the context are very different.

Abstract
AIM To estimate the long-term efficacy of an internet-based brief intervention (IBI) in decreasing alcohol use among men on (1) number of drinks/week and (2) monthly or more binge drinking prevalence. In addition, overall changes in alcohol use were assessed. DESIGN Participants in a cohort study were recruited in a two parallel-group randomized controlled trial of an IBI versus no-intervention control condition, showing a positive intervention effect at 6 months. As part of the regular cohort assessments, participants were re-assessed 47 months after the initial trial, offering an opportunity to determine long-term efficacy. SETTING Young Swiss men from the general population. PARTICIPANTS Of 737 randomized trial participants with unhealthy alcohol use (> 14 drinks/week or ≥ 6 drinks/occasion at least monthly, or Alcohol Use Disorders Identification Test (AUDIT) ≥ 8), 626 completed a cohort assessment at mean ± standard deviation (SD) = 47.4 ± 2.6) months after their randomized trial baseline assessment. INTERVENTION IBI included normative and personalized feedback on alcohol use, risk indicators, information about alcohol and health and recommendations; controls: assessment only. MEASUREMENTS Self-reported number of drinks/week and monthly or more binge drinking prevalence. FINDINGS Comparisons at follow-up were adjusted for baseline drinking. Missing values were replaced with the last observation carried forward. There was no evidence of differences between the IBI and control group on either the number of drinks/week [IBI: 10.8 (14.2); control: 10.7 (14.1), P = 0.8] or monthly or more binge drinking prevalence (IBI: 65.1%; control: 63.5%, P = 0.5). Although there was no evidence of overall change from baseline in number of drinks/week [9.8 (7.9) at baseline, 10.8 (14.1) at 47 months, P = 0.051], there was evidence that monthly or more binge drinking prevalence had decreased during the follow-up time (84.9% at baseline, 64.3% at 47 months, P < 0.001). CONCLUSIONS An internet-based brief intervention directed at unhealthy alcohol use among young men does not appear to reduce drinking over the long-term.
