[Tobacco use and illicit substance use disorders: what should we have to do?]

Rising trends in the burden of cardiovascular comorbidities and major adverse cardiovascular events among young female smokers in two national cohorts studied ten years apart (2017 vs. 2007)

BACKGROUND

Ample evidence suggests that female smokers face a greater risk of smoking-related health problems than male smokers. Due to the growing number of young smokers in the United States, there has been limited information on the effects of smoking on young female smokers over the past decade.

METHODS

Hospitalizations of young (18-44 years) female tobacco smokers were identified using the National Inpatient Sample datasets from 2007 and 2017. We compared differences in admission frequency, comorbidity burden, in-hospital outcomes [all-cause mortality and major adverse cardiac events (MACE)], and resource utilization between two young cohorts separated by 10 years.

RESULTS

In 2007, there were 665,901 admissions among young female smokers (median age: 35), compared to 1,224,479 admissions (median age: 32) in 2017. In both cohorts, white female smokers accounted for most admissions, followed by blacks. In 2017, the prevalence of alcohol abuse, hyperlipidemia, uncomplicated diabetes, and chronic pulmonary disease decreased relative to the 2007 cohort, whereas the prevalence of deficiency and chronic blood loss anemias, diabetes with complications, drug abuse, hypertension, congestive heart failure, depression, liver disease, and obesity increased significantly (p<0.001). The 2017 cohort had significantly higher odds of all-cause mortality [aOR 1.25 (95%CI: 1.16-1.35)] and a higher risk of MACE [aOR 1.17 (95%CI:1.14-1.20)] upon multivariable adjustment. (p<0.001). Comparatively, the 2017 cohort had fewer routine discharges and higher home healthcare needs than the 2007 cohort.

CONCLUSIONS

In this decade-apart analysis, the study reveals rising trends in the burden of comorbidities, MACE, and healthcare resource utilization in admissions (regardless of the primary cause) among relatively younger female smokers. It is crucial to educate young female smokers about the detrimental effects of tobacco and polysubstance abuse on cardiovascular outcomes.

[Bronchial diseases and heroin use. A systematic review]

INTRODUCTION

Heroin use can cause respiratory complications including asthma, chronic obstructive pulmonary disease (COPD) and bronchiectasis (BD).

OBJECTIVES

A general review of the literature presenting the data on the relationships between heroin consumption and bronchial complications, while underlining the difficulties of diagnosis and management.

DOCUMENTARY SOURCES

Medline, 1980-2022, keywords "asthma" or "bronchospasm" or "COPD" or "bronchiectasis" and "heroin" or "opiate" or "opiates", with limits pertaining to "Title/Abstract". Concerning asthma, 26 studies were included, as were 16 for COPD and 5 for BD.

RESULTS

Asthma and COPD are more prevalent among heroin addicts, who are less compliant than other patients with their treatment. The authors found a positive association between frequency of asthma exacerbations, admission to intensive care and heroin inhalation. Late diagnosis of COPD worsens the course of the disease; emphysema and BD are poor prognostic factors.

CONCLUSION

Bronchial diseases in heroin users can be identified by means of respiratory function exploration and chest CT scans. These tests should be performed frequently in view of optimizing their care, which includes their weaning themselves from addictive substances.

High smoking and low cessation rates among patients in treatment for opioid and other substance use disorders

BACKGROUND

Smoking is a well-documented cause of health problems among individuals with substance use disorders. For patients in opioid maintenance treatment (OMT), the risk for somatic health problems, including preventable diseases associated with tobacco smoking, increases with age. Our aim was to describe smoking among patients entering substance use disorder (SUD) treatment, investigate changes in smoking from the start of treatment to 1-year follow-up, and explore factors related to smoking cessation.

METHODS

We employed data from the Norwegian Cohort of Patient in Opioid Maintenance Treatment and Other Drug Treatment Study (NorComt). Participants were 335 patients entering SUD treatment at 21 participating facilities across Norway. They were interviewed at the start of treatment and at 1-year follow-up. The main outcomes were smoking and smoking cessation by treatment modality. A logistic regression identified factors associated with smoking cessation.

RESULTS

High levels of smoking were reported at the start of treatment in both OMT (94%) and other SUD inpatient treatment patients (93%). At 1-year follow-up most patients in OMT were still smoking (87%), and the majority of the inpatients were still smoking (69%). Treatment as an inpatient was positively associated and higher age was negatively associated with smoking cessation. Most patients who quit smoking transitioned to smokeless tobacco or kept their existing smokeless habit.

CONCLUSION

As illustrated by the high smoking prevalence and relatively low cessation levels in our sample, an increased focus on smoking cessation for patients currently in OMT and other SUD treatment is warranted. Harm-reduction oriented smoking interventions may be relevant.

[Asthma and cannabis, cocaine or heroin use]

INTRODUCTION

The use of cannabis, cocaine or heroin can be responsible for many respiratory complications including asthma.

OBJECTIVES

The aim of this systematic literature review of data was to expose the relations between cannabis, cocaine or heroin use and asthma.

RESULTS

Cannabis, cocaine or heroin use by inhalation may be responsible for respiratory symptoms (cough, wheezing), asthma onset, acute asthma exacerbations (which may require intubation and invasive ventilation) or deaths related to asthma. Lower adherence to asthma treatment is also observed. Cannabis induces a rapid bronchodilator effect. In contrast, its chronic use may induce a decrease in specific airway conductance. Studies on forced expiratory volume in one second (FEV1) reduction or decline are discordant.

CONCLUSION

Cannabis, cocaine or heroin use must be considered in cases of acute respiratory symptoms or asthma exacerbation in young persons and practitioners must help illicit substance users to stop their consumption.

Erectile Dysfunction Symptoms in Polydrug Dependents Seeking Treatment

OBJECTIVE

To assess erectile dysfunction (ED) symptom prevalence, sexual behavior conditions, and risk factors associated to ED in a male polydrug dependent sample.

METHODS

A cross-sectional design study was conducted with 102 substance-dependent male polydrug users who sought outpatient treatment in São Paulo, Brazil. Sociodemographic data, drug of choice, chronic disease questions, sexually transmitted infections, International Index of Erectile Function (IIEF) scale, Sexual Addiction Screening Test (SAST), and WHOQOL-Bref instrument were used.

RESULTS

The erectile dysfunction prevalence was 32.3% and it was related to the marital status (single) (p < 0.001), occupational status (fully unemployed) (p < 0.001), presenting a chronic disease (p = 0.027), and with types of sexual partnerships (occasional partner) (p < 0.001). Alcohol (73.5%), tobacco (79.4%), cannabis (83.3%), and cocaine (snorted 78.4% and smoked 42.2%) were the drugs of choice. The ED risk decreased when marital status was married (odds ratio = 3.2 CI95% 1.411-7.518) and with chronic disease (odds ratio 0.06 CI95% 0.00-0.97), while having occasional sexual partners increased 14 times ED risk (OR 14.0 CI95%1.62-122.18). There were no significant associations between quality of life, DOC and ED.

CONCLUSION

Approximately one third of the substance dependents in this sample presented ED. There is a need to integrate psychiatric and clinical care in substance treatment services, and to improve the provision of sexual health care and support available for this population.

[Asthma and heroin use]

INTRODUCTION

Heroin use can be responsible for many respiratory complications including asthma.

OBJECTIVES

Systematic literature review of data on asthma in heroin users.

DOCUMENTARY SOURCES

Medline®, on the period 1980-2017 with the following keywords: keywords: "asthma" or "bronchospasm" and "heroin" or "opiate" or "opiates", limits "title/abstract"; the selected languages were English or French. Among 97 articles, 67 abstracts have given use to a dual reading to select 23 studies.

RESULTS

The seven case reports included 21 patients (mean age: 28 years [19-46 years]; sex-ratio: 2.5 [males: 71.5%]). Heroin was inhaled (71.4%), sniffed (19%) or injected by intravenous route (9.5%). Associated addictive substances were tobacco (81%), cannabis (38%), alcohol (4.7%) and cocaine (4.7%). Outcome was fatal in 3 subjects (14.3%). Other studies included one cross-sectional study, 3 case-control studies and 12 longitudinal studies (11 retrospective studies and one prospective study). The proportion of heroin users was higher in asthmatic subjects and the prevalence of asthma and bronchial hyperreactivity was higher in heroin users. Heroin use can be responsible for asthma onset, with a temporal relationship between the onset of heroin use and asthma onset in 28 to 31% of subjects. A positive association between inhaled heroin use and acute asthma exacerbation was observed. Asthma treatment observance was lower in heroin users. In case of asthma exacerbation, heroin users were more likely to seek care in the emergency department, to be admitted in intensive care units and to require intubation and invasive ventilation. Asthma deaths related to heroin use mainly occurred following an intravenous injection (especially in the case of overdose), but also following heroin use by nasal (sniff) or pulmonary route.

CONCLUSION

Heroin use may be responsible for asthma onset, acute asthma exacerbations (which may require intubation and invasive ventilation) or deaths related to asthma. Heroin use must be sought in case of asthma exacerbation in young persons and practitioners must help heroin users to stop their consumption.

[Cannabis smoking and lung cancer]

Cannabis is the most commonly smoked illicit substance in the world. It can be smoked alone in plant form (marijuana) but it is mainly smoked mixed with tobacco. The combined smoking of cannabis and tobacco is a common-place phenomenon in our society. However, its use is responsible for severe pulmonary consequences. The specific impact of smoking cannabis is difficult to assess precisely and to distinguish from the effect of tobacco. Marijuana smoke contains polycyclic aromatic hydrocarbons and carcinogens at higher concentration than tobacco smoke. Cellular, tissue, animal and human studies, and also epidemiological studies, show that marijuana smoke is a risk factor for lung cancer. Cannabis exposure doubles the risk of developing lung cancer. This should encourage clinicians to identify cannabis use and to offer patients support in quitting.
