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.
背景：在法国 COVID-19 大流行的第一波期间，封锁措施引发了人们对使用非法药物者的严重公共卫生关注，尤其是在心理健康方面。我们评估了法国第一次封锁期间每日吸食大麻者的大麻使用情况的变化及其相关因素。
方法：CANNAVID 是一项法国全国性的、基于网络的横断面调查，于 2020 年 4 月 17 日至 5 月 11 日进行。邀请年龄≥18 岁且居住在法国的每日吸食大麻者参与研究。通过广告邀请受访者通过专门的在线平台完成一份特定的问卷。我们分析了第一次封锁期间（即停止、减少、不变或增加）大麻使用情况的变化，并进行了多变量逻辑回归分析，以评估这些变化的相关因素。
结果：在 4019 名参与者中，74.0%为男性。中位年龄为 27 岁（四分位距：22-37）。关于大麻使用情况，293 人（7.3%）停止使用，1153 人（28.7%）减少使用，1146 人（28.5%）未改变使用量，1427 人（35.5%）增加了使用量。多变量逻辑回归模型揭示了与大麻使用变化相关的几个社会人口学、行为和健康相关因素。与在封锁期间大麻使用水平不变的参与者相比，增加和停止大麻使用的参与者更有可能增加烟草和酒精使用，并经历抑郁和睡眠障碍加剧。停止使用大麻的参与者也更有可能增加苯二氮䓬类药物的使用，并在封锁期间经历疼痛加剧。
结论：法国第一次与 COVID-19 相关的封锁对每日吸食大麻者的消费模式产生了不同的影响。大多数研究受访者报告了他们的大麻消费模式的变化。报告大麻使用稳定的人更有可能报告较少的负面变化。需要为这一人群提供具体的干预措施，并进行研究以评估这些变化的长期影响。
