[Opioid overdose prevention and naloxone diffusion (POP program): Results of an overview conducted among addiction specialized centres]. / Prévention des surdoses opioïdes et diffusion de naloxone (programme POP) : résultats d'un état des lieux réalisé auprès des structures d'addictologie.

INTRODUCTION: In France, opioids are responsible for the majority of overdose deaths in France. The antidote naloxone is available in France in take home formulations since 2016. Addiction specialized centres are in front-line for naloxone diffusion. The objective was to provide an overview of professional practices, difficulties and needs regarding overdose prevention and naloxone diffusion in these centres of the Provence-Alpes-Côte d'Azur (PACA) region. METHODS: The POP programme "Prevention and harm reduction of opioid overdoses in PACA region" aims to improve the care of patients at risk of overdose and facilitate naloxone diffusion. The 75 addiction specialized centres of the PACA region were invited to respond to a semi-structured interview or a telephone questionnaire. Data collected included 2020 centres' activity and professionals' perceptions of overdose risk in their active file, their practices, difficulties and needs. RESULTS: Overall, 33 centres answered. Among them, 22 were dispensing naloxone with a mean of 20 kits dispensed in 2020 (min-max: 1-100). Two strategies were pointed out: systematically offering of naloxone to all opioids users or targeting people considered at risk. Several difficulties limiting naloxone diffusion were expressed: a lack of knowledge from opioids users, refusal from people not feeling concerned or refusing the injectable formulation, a lack of training of some professionals to be comfortable with the tool or reglementary or time constraints. CONCLUSION: Naloxone diffusion is incrementally getting into common practices. However barriers are persisting. On the basis of expressed difficulties and needs, information and training materials were co-designed and diffused.

Changes in cannabis use and associated correlates during France's first COVID-19 lockdown in daily cannabis users: results from a large community-based online survey.

BACKGROUND: Lockdown measures during the first wave of the COVID-19 pandemic in France led to serious public health concerns over people who use illicit drugs, especially in terms of mental health. We assessed changes in cannabis use during the first lockdown in France among daily cannabis users and associated correlates. METHODS: CANNAVID is a French, national, cross-sectional web-based survey, conducted from 17 April to 11 May 2020. Daily cannabis users aged ≥ 18 years and living in France were invited to participate through advertisements. Respondents completed an ad hoc questionnaire on a dedicated online platform. We analyzed changes in cannabis use during the first lockdown (i.e., stopped, decreased, unchanged, or increased) and performed a multinomial logistic regression analysis to evaluate correlates of these changes. RESULTS: Of the 4019 participants, 74.0% were men. Median age was 27 years (interquartile range: 22-37). With regard to cannabis use, 293 (7.3%) persons stopped, 1153 (28.7%) decreased, 1146 (28.5%) did not change, and 1427 (35.5%) increased their use during the lockdown. A multinomial logistic regression model revealed several sociodemographic, behavioral and health-related factors associated with changes in cannabis use. Compared with participants with an unchanged level of cannabis use during the lockdown, those who increased and those who stopped cannabis use were more likely to have increased tobacco and alcohol use and to have experienced depression and sleep disorders intensification. Those who stopped cannabis use were also more likely to have increased benzodiazepine use and to have experienced pain increase during lockdown. CONCLUSIONS: France's first COVID-19-related lockdown had a differential impact on daily cannabis users' consumption patterns. Most study respondents reported changes to their cannabis consumption pattern. Those who reported a stable cannabis use were more likely to report fewer negative changes. Specific interventions are needed for this population, as well as research to assess the long-term impacts of these changes.
