The relationship between cannabis use and violence, and to what extent this association is causal in nature, remains unclear. The aim of this scoping review was to ascertain whether cannabis use increases the risk of violence and aggression in adults. Because cannabis use can result in irritability, disinhibition, and altered cognition, it is plausible that its use increases the risk of violence and aggression and that this association is exacerbated in psychiatric illness. A search of the literature using PubMed, Scopus, and PsycINFO databases was performed; all materials published in English until April 2020 were considered. Peer-reviewed publications that assessed cannabis use and perpetration of violence or aggression in adults were included in this review. Of the 327 articles that were screened for eligibility, 19 articles met inclusion criteria for this review. Results suggest that there is a link between cannabis use and violence; however, this relationship is strictly correlational, and the strength of this relationship varies depending on the population (e.g., populations with severe and persistent mental illness versus the general population). These findings have important ramifications for treatment considerations and for public health and safety approaches.
大麻使用与暴力之间的关系，以及这种关联在多大程度上是因果关系，仍不明确。本范围综述的目的是确定大麻使用是否会增加成年人暴力和攻击行为的风险。由于大麻使用会导致易怒、行为失抑制和认知改变，因此其使用增加暴力和攻击行为风险且这种关联在精神疾病中会加剧是有道理的。我们使用PubMed、Scopus和PsycINFO数据库对文献进行了检索；纳入了截至2020年4月以英文发表的所有材料。本综述纳入了评估成年人中大麻使用与暴力或攻击行为实施情况的同行评审出版物。在筛选 eligibility的327篇文章中，有19篇符合本综述的纳入标准。结果表明大麻使用与暴力之间存在联系；然而，这种关系严格来说只是相关性的且这种关系的强度因人群而异（例如，患有严重和持续性精神疾病的人群与一般人群）。这些发现对治疗考量以及公共卫生和安全方法具有重要影响。
