BackgroundOn the brink of the opening of the first French drug consumption room in Paris, the general opinion of the local involved health care professionals and drug users was not known. The objective of this study was to determine their expectations and to search for influencing factors.MethodWe carried out a quantitative cross-sectional study. A multiple choice questionnaire was proposed to the surrounding willing general practitioners (GPs) and pharmacists, to the emergency doctors of Lariboisière hospital, and to the professionals of the harm reduction facilities and their drug users (PWUD). For each question, there was a choice between seven answers, from “− 3” (very negative impact) to “+ 3” (very positive impact). The influence of the characteristics of each group on its mean answers was explored by Mann-Whitney, Kruskal-Wallis, and Spearman’s tests.ResultsThe median expectations among the groups of responding GPs (N = 62), other health care professionals (N = 82), and PWUD (N = 57) were mainly positive. They thought that the drug consumption room (DCR) would improve the health of PWUD, reduce their at-risk behaviors, would not increase drug use or drug dealing in the neighborhood, and would reduce nuisance in the public space. Only the group of GPs expressed that the DCR could decrease the quietness of the neighborhood, and only the group of PWUD had higher expectations that the DCR would decrease the number of arrests and the number of violent behavior. GPs’ expectations were significantly better in terms of health improvement of PWUD and reducing their precariousness if they had a previous experience in addiction medicine (Mann-Whitney, p = 0.004 and p = 0.019), with a longer practice (Spearman’s rho, p = 0.021 and p = 0.009), and if they were currently prescribing opioid substitution treatments (Mann-Whitney, p = 0.030 and p = 0.002).Among non-GPs, those who were working in addiction medicine centers had significantly better expectations than pharmacists, and the professionals of the local emergency department had intermediate expectations.ConclusionsHealth care professionals and drug users had a positive opinion of the to-be-created Parisian drug consumption room. Experience in addiction medicine influenced positively health professionals’ expectations.

Purpose: Individual and family characteristics early on in life are associated with adolescent smoking; however, their role with regard to long-term tobacco smoking trajectories into young adulthood is not well-known, which is what we set out to study using data from a longitudinal community-based cohort. Methods: We used data from 2,025 youths in France (12–26 years at baseline, 16 years of follow-up), participating in the longitudinal TEMPO cohort study. First, we modeled smoking trajectories from adolescence onwards using Group-Based Trajectory Modeling, by using the declared consumption of cigarettes at different ages. Second, among trajectories of smokers, associations with individual and family characteristics in childhood and adolescence were studied using multinomial logistic regression. Results: We observed 5 smoking trajectories: non-smokers (62.3%), 3 groups of persistent smokers with different levels of tobacco use (low, intermediate, high), and a group characterized by high-level smoking followed by cessation. Among participants who were lifetime smokers (n = 763), the trajectory of tobacco use was associated with early substance use initiation, academic attainment, grade retention, and parental smoking. Early tobacco and cannabis use initiation predicted high-level tobacco use, whether it persisted (OR 2.29, 95% CI 1.23–4.28) or not (OR 2.99, 95% CI 1.59–5.63). Grade retention and parental smoking predicted persistent smoking of intermediate (respectively OR 1.53, 95% CI 1.03–1.92; OR 1.74, 95% CI 1.03–2.92) or high level use (respectively OR 1.74, 95% CI 1.07–2.85; OR 1.70, 95% CI 0.91–3.18). Poor academic attainment predicted all 3 smoking trajectories, especially persistent high-level smoking (no high school degree: OR 5.29, 95% CI 1.65–16.97, vocational degree: OR 1.94, 95% CI 0.99–3.80). Conclusions: Tobacco smoking trajectories from adolescence to adulthood are associated with early substance use initiation, parental smoking, and academic difficulties.

Background The prevalence of cognitive impairment is high among alcohol‐dependent patients. Although the clinical presentation of alcohol‐related cognitive disorder (ARCD) may resemble that of Alzheimer’s disease (AD), the prognosis and treatment of the 2 diseases are different. Cerebrospinal fluid (CSF) biomarkers (tau, phosphorylated tau, and amyloid β) have high diagnostic accuracy in AD and are currently being used to discriminate between psychiatric disorders and AD, but are not used to diagnose ARCD. The aim of this study was to characterize CSF biomarkers in a homogeneous, cognitively impaired alcohol‐dependent population. Methods This single‐center study was conducted in an addiction medicine department of a Parisian Hospital. We selected patients with documented persistent cognitive impairment whose MoCA (Montreal Cognitive Assessment) score was below 24/30 after at least 1 month of documented inpatient abstinence from alcohol. We measured the CSF biomarkers (tau, phosphorylated tau, and amyloid β 1‐42 and 1‐40) in 73 highly impaired alcohol‐dependent patients (Alcohol Use Disorders Identification Test score over 11 for women and 12 for men) with. Results Patients' average age was 60 ± 9.1 years and 45 (61.6%) had a normal CSF profile, 8 (11.0%) had a typical CSF AD profile, and 20 (27.4%) had an intermediate CSF profile. Conclusions This study revealed a high prevalence of AD in alcohol‐dependent patients with persistent cognitive deficits and several anomalies in their CSF profiles. Thus, it is important to consider AD in the differential diagnosis of persistent cognitive deficits in patients with alcohol dependence and to use CSF biomarkers in addition to imaging and neuropsychological testing to evaluate alcohol‐related cognitive impairment.
