Abstract
Objective: Given the interest in the potential effects of cannabis on medical students, this study aims to establish the prevalence of recreational use within this population.
Methods: We searched MEDLINE, LILACS, PubMed, Embase, PsycINFO/PsycArticles/APA Books), and SciELO for observational studies published before June 9, 2025, that reported cannabis use prevalence among medical students. We conducted subgroup analyses based on gender, study cycle, school type, decade of publication, and world region. Data were pooled using a random-effects model.
Results: Our search identified 109 studies meeting the inclusion criteria, published between 1971 and 2025, encompassing data from 62,444 participants from 32 countries. Lifetime prevalence was 29.2%, past year 20.5%, past month 9.2%, and past week 5.1%. Global prevalence declined from 38.4% in the 1970s (95% CI 19.2-57.7) to 18.1% in the 2000s (95% CI 13.6-23.8), increased to 30.4% in the 2020s (95% CI 19.2-41.6), driven by trends in Latin America, Asia, and Africa. The lowest prevalence was in Asia (11.5%, 95% CI 07.1-15.8) and the highest in Anglo-Saxon America (59.7%, 95% CI 53.1-66.3).
Conclusions: Cannabis use is prevalent among medical students, with increasing trends and regional variations. Targeted interventions are needed to raise awareness of associated risks.
目的：考虑到对大麻对医学生的潜在影响的兴趣，本研究旨在确定这一人群中娱乐性使用大麻的流行程度。方法：我们检索MEDLINE、LILACS、PubMed、Embase、PsycINFO/PsycArticles/APA Books)和SciELO，检索2025年6月9日之前发表的关于医学生大麻使用流行率的观察性研究。我们根据性别、学习周期、学校类型、出版年代和世界地区进行了分组分析。数据采用随机效应模型汇总。结果：我们的搜索确定了109项符合纳入标准的研究，发表于1971年至2025年之间，包括来自32个国家的62,444名参与者的数据。终生患病率29.2%，过去一年患病率20.5%，过去一个月患病率9.2%，过去一周患病率5.1%。全球患病率从20世纪70年代的38.4% （95% CI 19.2-57.7）下降到21世纪头十年的18.1% (95% CI 13.6-23.8)，到21世纪20年代上升到30.4% (95% CI 19.2-41.6)，受拉丁美洲、亚洲和非洲趋势的推动。发病率最低的是亚洲（11.5%，95% CI为7.01 -15.8），最高的是盎格鲁-撒克逊美洲（59.7%，95% CI为53.1-66.3）。结论：大麻的使用在医学生中很普遍，有增加的趋势和区域差异。需要采取有针对性的干预措施，以提高对相关风险的认识。
