The Association of Tobacco Smoking, Second-hand Smoke, and Novel Tobacco Products With COVID-19 Severity and Mortality in Italy: Results From the COSMO-IT Study.

BACKGROUND: Despite the robust evidence of an excess risk of coronavirus disease 2019 (COVID-19) severity and mortality in ever smokers, the debate on the role of current and ex-smokers on COVID-19 progression remains open. Limited or no data are available on the link between electronic cigarette (e-cigarette), heated tobacco product (HTP) and second-hand smoke (SHS) exposure and COVID-19 progression. To fill this knowledge gap, we undertook the COvid19 and SMOking in ITaly (COSMO-IT) study. METHODS: A multi-centre longitudinal study was conducted in 2020-2021 in 24 Italian hospitals on a total of 1,820 laboratory-confirmed COVID-19 patients. We estimated multivariable odds ratios (OR) and 95% confidence intervals (CI) to quantify the association between smoking-related behaviours (ie, smoking status, e-cigarette and HTP use, and SHS exposure) and COVID-19 severity (composite outcome: intubation, intensive care unit admission and death) and mortality. RESULTS: Compared to never smokers, current smokers had an increased risk of COVID-19 mortality (OR 2.17; 95% CI, 1.06-4.41). E-cigarette use was non-significantly associated to an increased risk of COVID-19 severity (OR 1.60; 95% CI, 0.96-2.67). An increased risk of mortality was observed for exposure to SHS among non-smokers (OR 1.67; 95% CI, 1.04-2.68), the risk being particularly evident for exposures of ≥6 hours/day (OR 1.99; 95% CI, 1.15-3.44). CONCLUSION: This multicentric study from Italy shows a dismal COVID-19 progression in current smokers and, for the first time, in SHS exposed non-smokers. These data represent an additional reason to strengthen and enforce effective tobacco control measures and to support smokers in quitting.

Impact of COVID-19 lockdown on smoking consumption in a large representative sample of Italian adults.

OBJECTIVES: Italy is one of the first countries that imposed a nationwide stay-at-home order during the COVID-19 outbreak, inevitably resulting in changes in lifestyles and addictive behaviours. The aim of this work is to investigate the impact of lockdown restrictions on smoking habits using data collected within the Lost in Italy project. METHODS: A web-based cross-sectional study was conducted on a representative sample of 6003 Italian adults aged 18-74 years. Study subjects were recruited from 27 April to 3 May 2020 and were asked to report changes in smoking habits before the lockdown and at the time of interview. RESULTS: During the lockdown, 5.5% of the overall sample quit or reduced smoking, but 9.0% of the sample started, relapsed smoking or increased their smoking intensity. In total, the lockdown increased cigarette consumption by 9.1%. An improvement in smoking habits was associated with younger age, occasional smoking and unemployment, whereas a worsening was mainly associated with mental distress. In particular, an increase in cigarette consumption during lockdown was more frequently reported among those with worsening quality of life (OR: 2.05; 95% CI: 1.49 to 2.80), reduction in sleep quantity (OR: 2.29; 95% CI: 1.71 to 3.07) and increased anxiety (OR: 1.83; 95% CI: 1.38 to 2.43) and depressive symptoms (OR: 2.04; 95% CI: 1.54 to 2.71). CONCLUSIONS: COVID-19 lockdown had a huge impact on smoking consumption of the Italian general population. The main concern is for smokers who increase their cigarette consumption due to an increased mental distress. Providing greater resources for cessation services capable of reducing mental health symptoms in smokers is urgently needed.

Impact of electronic cigarette and heated tobacco product on conventional smoking: an Italian prospective cohort study conducted during the COVID-19 pandemic.

OBJECTIVE: Debate continues about whether electronic cigarettes (e-cigarettes) and heated tobacco products (HTP) reduce or increase the probability of smoking, with many studies compromised by stated or unstated conflicts of interest. We undertook a longitudinal study in Italy. METHODS: 3185 Italian participants aged 18-74 years provided baseline (April-May) and follow-up (November-December) responses in 2020, reporting smoking status and use of e-cigarettes and HTP. We tracked transitions over that period and reported risk ratios (RR) and corresponding 95% CIs for changes in smoking in relation to baseline use of e-cigarettes and HTPs. RESULTS: Never cigarette smokers who used e-cigarettes at baseline were much more likely to start smoking (compared with never users, RR 8.78; 95% CI: 5.65 to 13.65) and current HTP users (RR 5.80; 95% CI: 3.65 to 9.20). Among ex-smokers, relapse (17.2%) at follow-up was more likely among e-cigarette (RR 4.25; 95% CI: 2.40 to 7.52) and HTP users (RR 3.32; 95% CI: 2.05 to 5.37). Among current smokers at baseline, those who had continued smoking at follow-up were 85.4% overall. These were more frequently current novel product users (compared with non-users, RR 1.10; 95% CI: 1.02 to 1.19 for e-cigarette users; RR 1.17; 95% CI: 1.10 to 1.23 for HTP users). CONCLUSIONS: Both e-cigarette and HTP use predict starting smoking and relapse, and appear to reduce smoking cessation. Due to the limited sample size within specific strata, the association with quitting smoking should be confirmed by larger prospective studies. These findings do not support the use of e-cigarettes and HTPs in tobacco control as a consumer product, at least in Italy.

New Synthetic Opioids Use among Patients in Treatment for an Opioid Use Disorder in Barcelona.

INTRODUCTION: New synthetic opioids (NSO), a class of new psychoactive substances (NPS), have recently emerged and pose an upcoming global public health challenge. The effects produced by NSO are similar to those from morphine, but they present greater pharmacological potency and abuse potential. Due to the increasing number of fatal overdoses and seizures in which NSO have been detected as heroin substitutes or adulterants, individuals with Opioid Use Disorder (OUD) represent a vulnerable population. The aim of our study was to describe and characterize from a gender perspective a Spanish cohort of potential conscious or unconscious NSO users. METHODS: A cross-sectional study was conducted in a cohort of OUD participants under treatment in addiction care services in Barcelona and Badalona, Spain. Clinical evaluation was performed through an ad hoc survey, a scale to evaluate reasons to use an opioid without prescription (range 0-4) and the Wellbeing Index (WHO-5) (range 0-100). Objective consumption of NSO was assessed by urinalysis carried out by two validated methods: high-sensitivity gas chromatography-mass spectrometry (MS) and ultra-high-performance liquid chromatography-high-resolution MS. RESULTS: A total of 154 participants with OUD were enrolled. They were mainly men (72.7%), mean age 47.8 years. Methadone was the predominant medication for opioid agonist treatment (mean dose 61.25 mg/day). A total of 32 (20.8%) participants reported having consumed some opioid to become "high" in the previous 3 months. The principal reasons for consuming illicit opioids were Replacing other drugs (mean 2.03) and Availability (mean 1.62), although Low price, was more highly valued by men (p = 0.045) and Shorter effect duration, most highly rated by women (p = <0.001). In the WHO-5, the mean score was 55 (SD = 30.1) without differences by gender. Fentanyl and derivatives or/and metabolites were detected in 7 (6.1%) participants, but illicit/non-prescribed NSOs were found in 5 out of 114 patients (4.4%), and other non-fentanyl opioids in 36 participants (26 men and 10 women). CONCLUSION: A non-negligible consumption of NSO-fentanyl's (positive detection in 6.1% of biological samples) was detected. The reasons for using these substances and also the well-being differed between the genders. There is therefore both voluntary and involuntary NSO consumption in our country which highlights the importance of approaching this potential public health problem.

COVID-19 lockdown impact on familial relationships and mental health in a large representative sample of Italian adults.

PURPOSE: Benefits of national-level stay-at-home order imposed in Italy to prevent SARS-CoV-2 transmission need to be carefully weighed against its impact on citizens' health. In a country with a strong familial culture and where welfare relies on households, confinement drastically decreased support provided by elder relatives, which may have resulted in mental health worsening. METHODS: A web-based cross-sectional study (LOST in Italy) was conducted on a representative sample of Italian adults during lockdown (27th of April-3rd of May 2020). We asked 3156 subjects to report on reduced help in housework and childcare from retired parents to assess the impact of confinement on mental health, through validated scales before and during lockdown. RESULTS: Overall, 1484 (47.0%) subjects reported reduced housework help from parents, and 769 (64.0%, of the 1202 subjects with children) diminished babysitting support. Subjects reporting reduced housework help had worsened sleep quality (multivariate odds ratio, OR = 1.74, 95% confidence interval, CI 1.49-2.03) and quantity (OR = 1.50, 95% CI 1.28-1.76), depressive (OR = 1.32, 95% CI 1.14-1.53) and anxiety symptoms (OR = 1.53, 95% CI 1.32-1.78), compared to those reporting unreduced help. Worsening in sleep quality (OR = 2.32, 95% CI 1.76-3.05), and quantity (OR = 1.80, 95% CI 1.36-2.37), depressive (OR = 1.79, 95% CI 1.39-2.31) and anxiety symptoms (OR = 1.90, 95% CI 1.48-2.46) was also associated with reduced babysitting help. Mental health outcomes were worse in subjects with poorer housing and teleworking during lockdown. CONCLUSION: Confinement came along with reduced familial support from parents, negatively impacting household members' mental health. Our findings might inform evidence-based family and welfare policies to promote population health within and beyond pandemic times.

Italians Do It Less. COVID-19 Lockdown Impact on Sexual Activity: Evidence From a Large Representative Sample of Italian Adults.

BACKGROUND: To explore how sexual activity was impacted by coronavirus disease 2019 (COVID-19) lockdown measures in the general adult population. METHODS: A cross-sectional survey was conducted among 6,003 Italian adults aged 18-74 years who were representative of the Italian general population. Study subjects were recruited at the time of the nationwide stay-at-home order (from April 27 to May 3, 2020). We identified characteristics associated with decreased frequency of sex during lockdown, differentiating between cohabiting and non-cohabiting subjects. RESULTS: Over one-third (35.3%) of Italians reported to have changed their sexual activity during lockdown (8.4% increased and 26.9% decreased). When focusing on cohabitants (N = 3,949, 65.8%), decreased sexual activity (20.7%) was more frequently reported by men (22.3%; compared to women, multivariable odds ratio 1.23; 95% confidence interval, 1.05-1.44), younger subjects (P for trend <0.001), more educated subjects (P for trend = 0.004), subjects living in smaller houses (P for trend = 0.003), and those reporting longer time spent outdoors before the lockdown (P for trend <0.001). CONCLUSIONS: COVID-19 lockdown drastically altered people's day-to-day life and is likely to have impacted lifestyle habits and behavioral risk factors, including sexual attitudes and practice. This is the first national population-level study exploring changes in sexual life in this COVID-19 era. As we report sexual practice to have been affected by lockdown restrictions, we suggest that the mental health, social, and other determinants of these changes are to be explored beyond imposed social distancing.

Disposition of cannabinoids and their metabolites in serum, oral fluid, sweat patch and urine from healthy individuals treated with pharmaceutical preparations of medical cannabis.

Recently, several countries authorized the use of cannabis flowering tops (dried inflorescences) with a standardized amount of Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD) and their acidic precursors [Δ-9-tetrahydrocannabinolic acid A (THCA-A) and cannabidiolic acid (CBDA)] to treat neurogenic pain. We studied the acute pharmacological effects and disposition of cannabinoids and their metabolites in serum, oral fluid, sweat patch and urine of 13 healthy individuals treated with medical cannabis decoction and oil. Cannabinoids and their metabolites were quantified by ultrahigh performance tandem mass spectrometry. Even if the oil contained a significantly higher amount of THC, the absorption of THC and its metabolites were similar in both herbal preparations. Conversely, whereas oil contained a significantly higher amount of CBD and a lower amount of CBDA, absorption was significantly higher after decoction intake. Only cannabinoids present in both herbal preparations (THC, CBD, THCA-A and CBDA) were found in oral fluid, due to the higher acidity compared with that of serum. THC metabolites urinary excretion was always higher after decoction administration. Decoction induced greater feeling of hunger and drowsiness than oil preparation. Pharmacokinetics of cannabinoids, their precursors and their metabolites in biological fluids of individuals treated with cannabis decoction and oil showed a high interindividual variability. The aqueous preparation was generally better absorbed than the oil, even if it contained a minor amount of THC, THCA-A and CBD.

Ultra-High Performance Liquid Chromatography-High Resolution Mass Spectrometry and High-Sensitivity Gas Chromatography-Mass Spectrometry Screening of Classic Drugs and New Psychoactive Substances and Metabolites in Urine of Consumers.

The use of the new psychoactive substances is continuously growing and the implementation of accurate and sensible analysis in biological matrices of users is relevant and fundamental for clinical and forensic purposes. Two different analytical technologies, high-sensitivity gas chromatography-mass spectrometry (GC-MS) and ultra-high-performance liquid chromatography-high-resolution mass spectrometry (UHPLC-HRMS) were used for a screening analysis of classic drugs and new psychoactive substances and their metabolites in urine of formed heroin addicts under methadone maintenance therapy. Sample preparation involved a liquid-liquid extraction. The UHPLC-HRMS method included Accucore™ phenyl Hexyl (100 × 2.1 mm, 2.6 µm, Thermo, USA) column with a gradient mobile phase consisting of mobile phase A (ammonium formate 2 mM in water, 0.1% formic acid) and mobile phase B (ammonium formate 2 mM in methanol/acetonitrile 50:50 (v/v), 0.1% formic acid) and a full-scan data-dependent MS2 (ddMS2) mode for substances identification (mass range 100-1000 m/z). The GC-MS method employed an ultra-Inert Intuvo GC column (HP-5MS UI, 30 m, 250 µm i.d, film thickness 0.25 µm; Agilent Technologies, Santa Clara, CA, USA) and electron-impact (EI) mass spectra were recorded in total ion monitoring mode (scan range 40-550 m/z). Urine samples from 296 patients with a history of opioid use disorder were examined. Around 80 different psychoactive substances and/or metabolites were identified, being methadone and metabolites the most prevalent ones. The possibility to screen for a huge number of psychotropic substances can be useful in suspected drug related fatalities or acute intoxication/exposure occurring in emergency departments and drug addiction services.

Prevalence of tobacco smoking and electronic cigarette use among adolescents in Italy: Global Youth Tobacco Surveys (GYTS), 2010, 2014, 2018.

This research aims to study tobacco smoking and vaping among adolescents in Italy through three repeat national cross sectional surveys conducted before (in 2010, 2014) and after (2018) the 2016 introduction of the European Union - Tobacco Product Directive (EU-TPD) and its transposition into Italy, and before Juul entered the Italian market in 2019. Prevalence of smoking and vaping, access to cigarettes and electronic cigarettes in adolescents aged 13-15 years were estimated from the 2010, 2014, and 2018 Global Youth Tobacco Surveys (N = 1587; N = 1428; N = 1518, respectively) conducted in Italy. Prevalence of current smokers and/or current vapers combined, accounting for dual users, non-significantly increased from 20.7% in 2010 to 27.9% in 2018. Although current smokers stalled around 20%, current vapers substantially increased from 0% in 2010, 7.4% in 2014, to 17.5% in 2018, and current exclusive vapers recorded an almost 3-fold significantly increase from 2.9% in 2014 to 8.2% in 2018. Moreover, 42% of ever vapers used nicotine-free electronic cigarettes, and only 5% of current users were frequent vapers (≥20 days in the past month). About 65% of current smokers and 76% of current vapers easily accessed to cigarettes or electronic cigarettes in 2018. After 2 years from its implementation in 2016, the EU-TPD does not seem to have slowed down the increase in vaping among Italian adolescents before Juul entered the Italian market. Additional research is needed in order to show a clear association between EU-TPD and changes in vaping and smoking in Italy and in the EU.

Δ9-Tetrahydrocannabinol and Cannabidiol Time Courses in the Sera of "Light Cannabis" Smokers: Discriminating Light Cannabis Use from Illegal and Medical Cannabis Use.

BACKGROUND: Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) time courses in serum and physiological and behavioral effects associated with smoking 1 or 4 "light cannabis" cigarettes were studied. Biomarkers to differentiate light cannabis versus illegal and medical cannabis use were also investigated. METHODS: Sera were obtained at different times from 6 healthy light cannabis consumers and 6 individuals who smoked 1 and 4 cigarettes, within 4 hours through a liquid-liquid method and analyzed by liquid chromatography-tandem mass spectrometry. RESULTS: In serum, minimal THC concentration was observed after a single cigarette smoke, while repeated smoking increased it by 1 order of magnitude. CBD concentrations were higher, but did not increase linearly, probably because it does not preferentially volatilize compared with THC. The highest THC and CBD concentrations were observed 0.5 hours after the start of the smoking of 1 cigarette. Serum THC ranged from 2.7 to 5.9 ng/mL, while serum CBD varied from 5.7 to 48.2 ng/mL. Similarly, the highest THC and CBD concentrations were observed 0.5 hours after the smoking of 4 cigarettes. Specifically, the ranges were THC: 11.0-21.8 ng/mL and CBD: 19.4-35.3 ng/mL. In both cases, the mean THC/CBD concentration ratio ranged from 0.2 to 0.9. There were no significant changes in blood pressure, heart rate, and body temperature, but participants who smoked 4 cigarettes experienced severe drowsiness. CONCLUSIONS: THC and CBD time courses in the sera of light cannabis smokers were similar to those previously observed in oral fluid and blood. Serum THC/CBD concentration ratio not higher than the mean value of 0.9 might be a useful biomarker to identify use of light cannabis versus that of illegal THC cannabis (where THC/CBD concentration ratios are generally greater than 10) or versus that of medical cannabis (where ratios are greater than 1). Consumers should be advised of possible drowsiness after he repeated smoking of light cannabis cigarettes.

THC and CBD concentrations in blood, oral fluid and urine following a single and repeated administration of "light cannabis".

Background "Light cannabis" is a product legally sold in Europe with Δ9-tetrahydrocannabinol (THC) concentration lower than 0.2% and variable cannabidiol (CBD) content. We studied THC and CBD excretion profiles in blood, oral fluid (OF) and urine after smoking one or four light cannabis cigarettes. Methods Blood, OF and urine samples were obtained from six healthy light cannabis consumers after smoking one 1 g cigarette containing 0.16% THC and 5.8% CBD and from six others after smoking four 1 g cigarettes within 4 h. Sample collection began 0.5 and 4.5 h after smoking one or four cigarettes, respectively. Cannabinoid concentrations were quantified by gas chromatography-mass spectrometry (GC-MS). Results At the first collection, the highest THC and CBD concentrations occurred in blood (THC 7.0-10.8 ng/mL; CBD 30.2-56.1 ng/mL) and OF (THC 5.1-15.5 ng/mL; CBD 14.2-28.1 ng/mL); similar results occurred 0.5 h after the last of four cigarettes in blood (THC 14.1-18.2 ng/mL, and CBD 25.6-45.4 ng/mL) and OF (THC 11.2-24.3 ng/mL; CBD 14.4-37.0 ng/mL). The mean OF to blood ratio ranged from 0.6 to 1.2 after one and 0.6 to 1.9 after four light cannabis cigarettes. THC/CBD ratios in blood and OF were never greater than 2. Urinary 11-nor-9-carboxy-THC concentrations peaked 8 h after one and four cigarettes. Conclusions OF was a valuable alternative to blood in monitoring consumption of light cannabis. Blood and OF THC/CBD concentration ratios, never exceeded 2, possibly providing a useful biomarker to identify light cannabis vs illegal higher THC cannabis use, where THC/CBD ratios are generally greater than 10.

Electronic cigarettes in Italy: a tool for harm reduction or a gateway to smoking tobacco?

INTRODUCTION: More than a decade after electronic cigarettes (e-cigarette) hit the European market, we are still debating whether they may help or hinder tobacco control. It is therefore useful to explore the potential net effect of e-cigarette use in the general population. METHODS: We annually conduct a face-to-face survey on smoking in Italy on a representative sample of the general population aged 15 years or over (52.4 million). A total of 15 406 subjects were interviewed in 2014-2018. We investigated the consequences of using e-cigarettes on tobacco smoking behaviour among ever and regular e-cigarette users. RESULTS: In all, 5.7% of our sample reported ever e-cigarette use. Multivariate analyses showed more use by men, ex-smokers and current smokers. E-cigarette use decreased with age and increased with education and calendar year. Only 1.1% of subjects were regular e-cigarette users. This prevalence rose from 0.4% in 2014-2015 to 1.8% in 2016-2017 and was 1.3% in 2018. Among 522 ever users, 13.2% stopped smoking after trying e-cigarettes and 22.2% started smoking or relapsed after using e-cigarettes. The corresponding estimates among regular users were 24.7% and 28.0%, respectively. CONCLUSIONS: Among Italian e-cigarette users, those (re)starting smoking after using e-cigarettes outnumber those who stop smoking after using e-cigarettes. From a public health point of view, e-cigarettes may have an unfavourable net effect. Consequently, if we are not able to prevent sales of e-cigarettes to non-smokers, this product will more likely stimulate smoking tobacco than reduce harm.

Herbal Preparations of Medical Cannabis: A Vademecum for Prescribing Doctors.

Cannabis has been used for centuries for therapeutic purposes. In the last century, the plant was demonized due to its high abuse liability and supposedly insufficient health benefits. However, recent decriminalization policies and new scientific evidence have increased the interest in cannabis therapeutic potential of cannabis and paved the way for the release of marketing authorizations for cannabis-based products. Although several synthetic and standardized products are currently available on the market, patients' preferences lean towards herbal preparations, because they are easy to handle and self-administer. A literature search was conducted on multidisciplinary research databases and international agencies or institutional websites. Despite the growing popularity of medical cannabis, little data is available on the chemical composition and preparation methods of medical cannabis extracts. The authors hereby report the most common cannabis preparations, presenting their medical indications, routes of administration and recommended dosages. A practical and helpful guide for prescribing doctors is provided, including suggested posology, titration strategies and cannabinoid amounts in herbal preparations obtained from different sources of medical cannabis.

[Smoking in cars and motorcycles in Italy over the last decade]. / Il fumo in macchina e in moto in Italia nell'ultimo decennio.

OBJECTIVES: to estimate the prevalence of smoking while driving a car or a motorcycle, and its determinants, and to analyze the trends of these habits before and after the transposition of the European Directive 40/2014 (Legislative Decree 6/2016) adopted in 2016, which bans smoking in cars in the presence of minors. DESIGN: eight different population-based surveys conducted in Italy by Doxa between 2007 and 2018. SETTING AND PARTICIPANTS: 21,807 subjects aged >=18 years, representative of the Italian adult population. MAIN OUTCOME MEASURES: prevalence of smokers who smoke while driving a car, with and without minors, or a motorcycle. Prevalence of non-smokers exposed to second-hand smoke (SHS) in cars, with or without minors. Estimate of multivariate odds ratios (ORs) and 95% confidence intervals (CIs), using multiple logistic regression models adjusted by gender, age, education, geographic area, and year of survey. RESULTS: the prevalence of smokers who smoked in cars decreased from 69.6% in 2007-2008 to 57.5% in 2016, and to 51.5% in 2017-2018. Those who smoked in cars in presence of minors were 20.9% in 2011-2012 and 11.7% in 2017-2018. The prevalence of smokers who smoked while driving a motorcycle decreased from 15.0% in 2007-2008 to 6.5% in 2017-2018. Smoking while driving a car in presence of minors decreased with increasing age (p=0.004) and education level (p=0.029) and was more frequent in Southern than in Northern Italy (OR 4.40; 95%CI 2.21-8.74). In 2017-2018, 16.2% of non-smokers reported being exposed to SHS in cars. Of these, 42.3% were exposed also in presence of minors. CONCLUSIONS: the tobacco control legislations adopted over the last 15 years, in particular the last one adopted in 2016, have largely contributed in reducing smoking in private vehicles, even in the presence of minors. This notwithstanding, 50% of Italian smokers smoke while driving and more than 15% of non-smokers are exposed to SHS in cars. It is suggested to adopt informative campaigns that inform people about the risks associated with smoking in cars, both for drivers and for passengers, and to increase the fines for those who smoke in cars in the presence of minors or driving a motorcycle.

[Smoking initiation in Italian regions, 2014, and Regional Prevention Plans]. / Iniziare a fumare nelle regioni italiane nel 2014 e Piani Regionali di Prevenzione.

OBJECTIVES: to evaluate smoking prevalence in adolescents by Italian region from the Health Behaviour Study in School-aged Children (HBSC) of 2014 and to correlate it with the presence, in the 2014-2018 Regional Prevention Plans (PRPs), of school-based smoking prevention interventions. SETTING AND PARTICIPANTS: the 2014 HBSC surveillance system provided data on 48,000 adolescents aged 11, 13, and 15 years; Ministry of Health provided data for each PRP on interventions with a tobacco control component and, among them, school-based smoking prevention interventions. MAIN OUTCOME MEASURES: weekly smoking prevalence; proportion of school-based smoking prevention interventions out of prevention interventions with tobacco control measures. RESULTS: regions with the highest weekly smoking prevalence were Sardinia and Apulia for all age groups, Abruzzo for 11- and 15-year-old children, Basilicata for 15-year-old children, Bolzano for girls aged 13 years old; Liguria for females, Molise, Calabria, and Veneto for males. In the regions with the highest prevalence of smoking in 2014, in girls aged 11 and 13 years (Sardinia, Apulia, Basilicata, Liguria, Bolzano), a greater proportion of school-based smoking prevention interventions to be developed in the period 2014-2018 have been recorded. CONCLUSIONS: smoking prevalence in Italian adolescents is high, especially in 15-year-old children. Implementing policies recommended by the World Health Organization - Framework Convention on Tobacco Control (higher tobacco taxes, anti-tobacco mass media campaigns, plain tobacco package) could work synergistically with school-based interventions in order to decrease tobacco initiation among adolescents in Italy.

Stimulant substance use and gambling behaviour in adolescents. Gambling and stimulant use. / Uso de sustancias estimulantes y comportamiento de juego en adolescentes. Juego y uso de estimulantes.

Gambling is widely recognized as an important public health problem. Despite the rising use of stimulant substances among adolescents, there are still very few studies focusing on whether adolescents' use of stimulants is associated with their gambling behaviour. Therefore, the aim of this study was to investigate the association between gambling habits and consumption of stimulants such as coffee, energy drinks, and new psychoactive substances in a sample of Italian adolescents. A survey was conducted in 2017 with a representative sample of Italians between the ages of 14-17 years, comprising 15,833 students attending 201 secondary schools. Logistic regression analyses were run to assess the association between at-risk/problem gambling (O1) and independent predictors: the model included independent variables (coffee, energy drinks and new psychoactive substance consumption) and covariates (demographic variables, social environment variables and risk-taking behaviour variables). A sensitivity analysis was also conducted to examine a second dependent variable regarding any experience of gambling behaviour (O2). Adolescents who were at-risk gamblers or problem gamblers were significantly more likely to consume energy drinks than non-gamblers or not-at-risk gamblers. A similar pattern was seen for consumption of new psychoactive substances. No significant association emerged with coffee consumption. The sensitivity analysis showed that, compared with non gamblers, the group of gamblers had higher odds for frequent coffee consumption, as well as for consumption of energy drinks and/or new psychoactive substances. Screening for gambling and stimulant use may provide important information, as it may be necessary to take action to reduce stimulant substance use as part of efforts to deal with unhealthy gambling habits.

El juego es un importante problema de salud pública ampliamente reconocido. A pesar del creciente uso de sustancias estimulantes entre los adolescentes, todavía son escasos los estudios centrados en verificar la existencia de una asociación entre el uso de estimulantes y los comportamientos relacionados con el juego en adolescentes. Por tanto, este estudio tuvo como objetivo investigar la asociación entre los hábitos relacionados con el juego y el consumo de sustancias estimulantes como el café, las bebidas energizantes y las nuevas sustancias psicoactivas en una muestra de adolescentes italianos. En 2017 se realizó una encuesta en una muestra representativa de jóvenes italianos de 14 a 17 años, constituida por 15 833 estudiantes provenientes de 201 escuelas de educación secundaria. Se realizó un análisis de regresión logística para evaluar la asociación entre juego de riesgo/juego problemático (R1) y factores predictivos independientes: el modelo incluyó variables independientes (café, bebida energética y consumo de nuevas sustancias psicoactivas) y otras covariables demográficas, del entorno social y de conductas de riesgo. También se realizó un análisis de sensibilidad para examinar una segunda variable dependiente con respecto a cualquier experiencia de conductas relacionadas con el juego (R2). Los adolescentes clasificados como jugadores de riesgo o jugadores con problemas tenían una probabilidad significativamente mayor de consumir bebidas energizantes que los no jugadores o los jugadores sin riesgo. Se observó un patrón similar en el consumo de nuevas sustancias psicoactivas. No se evidenció ninguna asociación significativa con el consumo de café. El análisis de sensibilidad mostró que, en comparación con los no jugadores, el grupo de jugadores tenía mayores probabilidades de consumo frecuente de café, bebidas energéticas y/o nuevas sustancias psicoactivas. La evaluación del juego y el uso de sustancias estimulantes puede proporcionar información importante. Por consiguiente, podría ser necesario tomar medidas para reducir el uso de sustancias estimulantes como parte de los esfuerzos dirigidos a lidiar con los hábitos de juego poco saludables.

Cannabinoids determination in bronchoalveolar lavages of cannabis smokers with lung disease.

Background Cannabis smoke affects the lungs similarly to tobacco smoke, causing symptoms such as increased cough, sputum, hyperinflation and chronic bronchitis. Chronic use can also cause serious lung diseases and airway obstruction. We developed and validated a method for the identification and quantification of cannabinol (CBN), cannabidiol (CBD), Δ-9-tetrahydrocannabinol (THC) and its metabolites 11-hydroxy-THC (11-OH-THC) and 11-nor-9-carboxy-THC (THC-COOH) in bronchoalveolar lavages (BALs) from hospitalized former or current tobacco smoking patients with lung disease and a long history of cannabis consumption and limited current tobacco use. Methods For the extraction of cannabinoids from BALs, a 1 mL sample was added with 300 µL of 0.1 N NaOH and 3 mL of hexane/ethyl acetate (9:1). The solvent was then evaporated to dryness. Trimethylsilyl derivatives were prepared and then analyzed by gas chromatography/mass spectrometry. Results The method was linear for the analytes under investigation with coefficients of determination of at least 0.99. Absolute analytical recovery was always better than 80%, imprecision and inaccuracy was always under 15%. Six cases out of 15 were positive for THC, CBN and CBD. In two BALs samples, the presence of 11-OH-THC was also measured while THC-COOH was not detected. In the six positive cases, the last cannabis smoking occurred in the previous 2-14 days. Conclusions This is the first time that cannabinoids have been detected in BALs, demonstrating the presence of a drug with its metabolites in a target organ of consumers who present with a lung disease. This occurrence let us hypothesize a role of cannabinoids in the development of the disease and prompted an investigation on possible associations between cannabis smoking and clinical outcomes in patients with lung disease and eventually evaluate a cytotoxic effect of cannabinoids themselves.

Cannabinoids Identification in Lung Tissues of Young Cannabis Smokers Operated for Primary Spontaneous Pneumothorax and Correlation with Pathologic Findings.

BACKGROUND: Several studies suggested the association between tobacco and cannabis smoking and the risk of primary spontaneous pneumothorax (PSP), but none demonstrated cannabinoids in human lung tissues. OBJECTIVES: The aim of this study was to identify cannabinoids in lung specimens of young cannabis smokers, operated for PSP, and investigate on their pathologic findings, to determine the role of cannabis in PSP pathogenesis. METHOD: A prospective, multicenter study was conducted, enrolling patients admitted for PSP. Inclusion criteria were PSP requiring surgical treatment and history of cannabis smoking, associated or not to tobacco. Control cases were nonsmokers, and tobacco only smokers operated for PSP. Lung apex wedge resection by video-assisted thoracic surgery was performed. Two lung specimens, for pathological and toxicological examination, were taken from each patient. RESULTS: Twenty-nine male patients were enrolled: 21 (72.4%) tobacco and cannabis smokers, 2 (7%) cannabis only smokers, 3 (10.3%) tobacco only smokers, 3 (10.3%) nonsmokers; all underwent lung apicectomy, 4 bilateral surgery, for a total of 33 procedures. Typical PSP pathologic findings were mainly detected in control cases, other alterations in cannabis users. Lung specimens resulted positive for cannabinoids on 22/33 cases (19/22 reported being, 3/22 not being cannabis smokers), negative on 11/33 (3/11 reported not being, 7/11 having been cannabis smokers, 1/11 cannabis smoker). CONCLUSIONS: Our study demonstrated the presence of cannabinoids and particular pathologic alterations in lung tissues of young cannabis smokers with PSP, supporting the correlation between this disease and marijuana abuse and suggesting spontaneous pneumothorax "secondary to marijuana" as a new nosological entity.

A long way to go: 20-year trends from multiple surveillance systems show a still huge use of tobacco in minors in Italy.

Background: Main aim was to describe youth smoking prevalence in Italy over the last two decades, and to provide recent trends in knowledge, attitudes towards smoking, awareness of anti-tobacco mass media campaigns, second-hand smoke (SHS) exposure and access to cigarettes. Methods: Figures from three surveillance systems, with 12 representative cross-sectional surveys (about 43 000 participants): European School Survey Project on Alcohol and Other Drugs, 15-16-year-old students, 1995-2015; Health Behaviour in School-aged Children, 11-, 13-, 15-year-old students, 2002-14 and Global Youth Tobacco Survey, 13-15-year-old students, 2010, 2014. Results: Among 11- and 13-year-old students, daily and non-daily smokers decreased by 30-50% from 2002 to 2014. Among 15-16-year-old adolescents, ever smokers significantly decreased by 10% in the period 1995-2015, whereas current and daily smokers have been stalling or even increased. Appeal of smoking increased in 2014 compared to 2010, perception of SHS as harmful, and awareness of recent anti-tobacco mass media campaigns decreased. Moreover, a significant 30% reduction in reporting retailers did not refuse to sell cigarettes to adolescents and a decrease in reporting to buy cigarettes were reported. Conclusions: Policies enforced in Italy over the last 20 years slightly reduced ever smokers, but did not decrease current and daily smokers in 15-16-year-old adolescents, and determined an impact among younger adolescents. Stricter rules on youth tobacco access reduced ease of access to cigarettes, but did not affect adolescents' tobacco use. Stronger tobacco control measures are urgently needed in order to determine a steeper decline in smoking prevalence in adolescents.

[Socioeconomic and regional inequalities in smoking cessation in Italy, 2014-2017]. / Disuguaglianze regionali e socioeconomiche nella cessazione del fumo in Italia, 2014-2017.

OBJECTIVES: to study regional differences in Italy of quit smoking attempts and of successful abstinence, in relation to socioeconomic status, cigarettes per day (cig/die), and smoking cessation method in a representative sample of the population resident in Italy. DESIGN: cross-sectional survey. SETTING AND PARTICIPANTS: in 2014-2017, PASSI survey (the ongoing Italian behavioural risk factor surveillancesystem) gathered data on smoking and sociodemographic characteristics of 35,157 smokers; 13,130 aged 18-69 years made >1 quit attempt in the previous year, 1,176 of them were successful quitters for >6 months. MAIN OUTCOME MEASURES: proportion of smokers who tried to quit; proportion of smokers who successfully quitted. RESULTS: about 35% of smokers made >1 quit attempt in the last year. Northern Italians and smokers with many economic difficulties were more likely to make a quit attempt, whereas heavy smokers were less likely. About 10% of attempters were abstinent for >6 months: from 6% in Campania and Abruzzo to 17% in the Bolzano province. Attempters who smoked <20 cig/die had higher likelihood to be abstinent, compared to those smoking <20 cig/die. Attempters with many economic difficulties had the lowest likelihood to be abstinent (7%), with no differences by region, educational level, quitting method. Attempters with no economic difficulties recorded the highest cessation rates (12%). Among them, those from Northern Italy, Tuscany, Marche, and Lazio (Central Italy), and Apulia (Southern Italy) compared to attempters from most Southern regions, and those with high education level or using traditional quitting methods compared to those using electronic cigarettes or unaided were more likely to be abstinent for >6 months. CONCLUSIONS: smokers with many economic difficulties in all Italy, and those with no economic difficulties residing in Umbria and in most Southern Italian regions, except for Basilicata and Puglia, recorded lower chances to quit. Regional differences may have two possible explanations integrating each other: Northern-Central regions are in a slightly more advanced stage in the tobacco epidemic; regions which developed specific tobacco control interventions in their Prevention Plans recorded higher quitting rates. Not-yet-implemented interventions could promote smoking cessation in smokers from Southern Italy and in those with lower socioeconomic status: reimbursement of smoking cessation treatments, a well-developed national Quitline linked to a webplatform and to mobile phone application or text-messaging, an opt-out smoking cessation service offered systematically to all smokers at every encounter in hospitals or health services.
