ABSTRACTBackgroundObservational studies suggest smoking, cannabis use, alcohol consumption, cannabis use, and substance use disorders (SUDs) may play a role in the susceptibility for respiratory infections and disease, including coronavirus 2019 (COVID-2019). However, causal inference is challenging due to comorbid substance use.MethodsUsing genome-wide association study data of European ancestry (data from >1.7 million individuals), we performed single-variable and multivariable Mendelian randomization to evaluate relationships between smoking, cannabis use, alcohol consumption, SUDs, and respiratory infections.ResultsGenetically predicted lifetime smoking was found to be associated with increased risk for hospitalized COVID-19 (odds ratio (OR)=4.039, 95% CI 2.335-6.985, P-value=5.93×10−7) and very severe hospitalized COVID-19 (OR=3.091, 95% CI, 1.883-5.092, P-value=8.40×10−6). Genetically predicted lifetime smoking was also associated with increased risk pneumoniae (OR=1.589, 95% CI, 1.214-2.078, P-value=7.33×10−4), lower respiratory infections (OR=2.303, 95% CI, 1.713-3.097, P-value=3.40×10−8), and several others. Genetically predicted cannabis use disorder (CUD) was associated with increased bronchitis risk (OR=1.078, 95% CI, 1.020-1.128, P-value=0.007).ConclusionsWe provide strong genetic evidence showing smoking increases the risk for respiratory infections and diseases even after accounting for other substance use and abuse. Additionally, we provide find CUD may increase the risk for bronchitis, which taken together, may guide future research SUDs and respiratory outcomes.

Background: Cannabis use has increased over the past several years as some countries have legalized its use for the treatment of certain medical conditions and/or for recreational use. Thus, concerns have risen about potential adverse health effects. Increasing number of reports have associated cannabis use with serious cardiovascular (CV) complications. Furthermore, there appears to be a likeness in the harmful health effects, especially on the CV and respiratory systems, of cannabis smoking to those of tobacco smoking. Objective: To review the CV effects of cannabis use and compare them with those of tobacco use. Methods: Articles were reviewed that were published in English literature reporting on cannabis and cannabinoid pharmacology and their effects on the CV system and their consequences. Emphasis was also placed on articles reporting on cannabis use in adolescents, exposure to secondhand smoke, its effect on exercise and finally its inter-relationship and similarities with tobacco use. Results: With growing cannabis use, an increasing number of reports have emerged associating marijuana use with serious and life-threatening CV complications, including acute coronary syndromes, potentially lethal cardiac arrhythmias and ischemic strokes. There are certain similarities of the deleterious CV and respiratory effects of cannabis smoking with those of tobacco smoking. Despite the difference in the active ingredients (tetrahydrocannabinol vs. nicotine), each substance produces a plethora of chemicals when smoked and these are largely identical; furthermore, due to different modes of smoking, cannabis chemicals are retained in the body for a longer time. Of course, concomitant tobacco and cannabis smoking is a perplexing factor in isolating damages specifically pertaining to cannabis use, while the health risk is additive. Although the mechanisms producing CV harm may be somewhat different between these two substances, the outcome appears similar, or even worse, as the effects may emerge at a younger age. Conclusion: There is an increasing concern that, apart from the mental health problem with cannabis smoking, societies may be facing another wave of a déjà vu/déjà vécu phenomenon similar to the tobacco smoking story.

Abstract Exposure to environmental tobacco smoke (ETS) is an important modifiable risk factor for child hospitalization, although its contribution is not well documented in countries where ETS due to maternal tobacco smoking is negligible. We conducted a birth cohort study of 1999 neonates between May 2009 and May 2010 in Nha Trang, Vietnam, to evaluate paternal tobacco smoking as a risk factor for infectious and non-infectious diseases. Hospitalizations during a 24-month observation period were identified using hospital records. The effect of paternal exposure during pregnancy and infancy on infectious disease incidence was evaluated using Poisson regression models. In total, 35.6% of 1624 children who attended follow-up visits required at least one hospitalization by 2 years of age, and the most common reason for hospitalization was lower respiratory tract infection (LRTI). Paternal tobacco smoking independently increased the risk of LRTI 1.76-fold (95% CI: 1.24–2.51) after adjusting for possible confounders but was not associated with any other cause of hospitalization. The population attributable fraction indicated that effective interventions to prevent paternal smoking in the presence of children would reduce LRTI-related hospitalizations by 14.8% in this epidemiological setting.

Cannabis is commonly used among people who drink alcohol, but findings are mixed regarding the direction of this relationship. The type of cannabis used [high-cannabidiol (CBD) vs. high-delta-9tetrahydrocannabinol (THC)] and motives for use (i.e., whether cannabis is used to treat a medical condition) may influence the relationship between cannabis and drinking. Specifically, CBD has shown preclinical promise in reducing alcohol consumption, and medical cannabis users report using cannabis to reduce drinking. This study leverages survey data from cannabis users who drink alcohol (N = 533). Respondents were categorized as using cannabis to treat (CTT) a medical condition or as individuals whose cannabis use is not intended to treat (NCTT) a medical condition and grouped based on the THC/CBD ratio of the flower or edible cannabis they typically use (e.g., “High-THC/CBD,” “Medium-THC/CBD” and “Low-THC/CBD”). The CTT group (n = 412) reported drinking significantly less frequently than the NCTT group (n = 121). Cannabinoid content of flower cannabis was associated with alcohol consumed on cannabis-use days, such that individuals in the High-THC/CBD group drink more on cannabis-use days compared to the Medium-THC/CBD group. Cannabinoid content of edible cannabis was associated with drinks per drinking occasion, such that the High-THC/CBD group consumed the most drinks and the Low-THC/CBD group consumed the fewest. For both edible and flower groupings, higher-THC/CBD cannabis was associated with more frequent co-use than lower-THC/CBD cannabis. Results suggest that whether someone uses cannabis to treat a medical condition may impact their drinking frequency, and the cannabinoid content in flower and edible cannabis impacts alcohol consumption.

Aim. We investigated the relationship between sex (genetic/biological) and gender (environmental/ cultural) factors in relation to adolescent tobacco smoking. Methods. A representative sample of 11,582 students from French secondary public schools participated in the study by completing a self-administered, standardised questionnaire. Results. Using the WHO classification for smoking in the youth, 15.6% of the adolescents were regular smokers, 7.7% occasional smokers, 17.9% experimental smokers and 4.8% ex-smokers, with no statistically significant gender difference. Taking non-smoking as a reference, puberty had a much greater effect on the likelihood of being a regular smoker [OR=18.0 (95% Confidence Interval: 9.6- 32)] than of being an experimental/occasional smoker [OR=3.7 (2.9-4.6)] among girls. For boys, the effect of puberty was not as great [OR=4.7 (3.5-6.5)] for regular vs. [OR=2.1 (1.8-2.5)] for experimental/occasional smokers). Similarly, illicit drug use had a larger effect on the likelihood of being regular smoker vs. non-smoker [OR=15.0 (12.0-20.0) in boys and 12 (8.8-16.0) in girls] than of being experimental/occasional smoker vs. a non-smoker [OR=4.8 (3.7-6.1) and 2.9 (2.1-3.9) respectively]. Other factors related to regular smoking were exposure to passive smoking and regular alcohol consumption. Living with both parents was a protective factor for life and regular smoking in both genders. Conclusions. Our results show that influential factors of sex-related (puberty), gender-specific (environmental tobacco smoking, alcohol consumption, drug abuse) or sex/gender (regular sexual intercourse) are related to the smoking behaviour in French adolescents.

<span style="font-family: TimesNewRomanPSMT; font-size: x-small;"><span style="font-family: TimesNewRomanPSMT; font-size: x-small;"><p>The description of alcohol and cannabis use in the period 1995-2009 is based on data from five sets of surveys. Sales figures for alcohol consumption are also included. Alcohol sales in Norway increased by 40 per cent during the period 1995-2009, from 4.8 to 6.7 litres of pure alcohol per inhabitant aged 15 years and over. This increase largely reflects a sharp increase in the sale of wine. Also when taking into account unregistered alcohol consumption, the consumption of alcohol increased considerably in Norway during the period in question. The increased alcohol consumption seems to be due to an increase in moderate alcohol consumers and/or an increase in situations involving moderate alcohol consumption. Population surveys indicate that there has been an increase in the proportion who drink alcohol and in the proportion of people who drink relatively often, but the increased drinking frequency is not accompanied by a corresponding increase in the proportion who often drink until they are intoxicated. On average, men drink more often and greater quantities than women, with the exception of wine. The proportion who drink alcohol at least twice a month or more has increased in all age groups, and the increase has been particularly marked among those above the age of 50. Despite a reduction in consumption among young people in recent years, consumption and drinking until intoxicated are still widespread. Young girls drink alcohol as often as boys and are equally often intoxicated. As for cannabis, there was an increase in the age group 15-20 years in the second half of the 1990s, followed by a decrease and stagnation since the turn of the millennium. There was little or no difference between boys and girls in the 15-20 age group in the use of cannabis, while among young adults, far more men than women reported that they had used cannabis</p></span></span>
