Cannabis consumption among aging adults in Canada is increasing. The aims of the study were to examine cannabis consumption patterns before and after non-medical cannabis legalization and assess whether these patterns differ between men and women. Data were analyzed from Canadian respondents in a repeat cross-sectional survey conducted in 2018-2021. Analyses were conducted among adults aged 55-65 ( = 18,177) who had consumed cannabis in the past 12-month ( = 4119). Past 12-month cannabis consumption significantly increased among 55-65-year-olds from 2018 (19.3%) to the first-year post-legalization in 2019 (24.5%; < .001), but remained stable thereafter (24.3%, and 25.6% in 2020 and 2021). More men reported past 12-month consumption than women (28.4% vs. 21.4%; < .001). A substantial number of cannabis consumers consumed to manage a physical or mental health condition. Targeted messaging might be beneficial for this age group, including possible interactions with other medications. This research may be helpful for informing age-adapted cannabis education.
加拿大老年人中使用大麻的情况正在增加。本研究的目的是调查非医用大麻合法化前后的大麻消费模式，并评估这些模式在男性和女性之间是否存在差异。数据来自于2018年至2021年进行的一项重复横断面调查中的加拿大受访者。分析在55至65岁的成年人（n = 18177）中进行，这些人在过去12个月内曾使用过大麻（n = 4119）。55至65岁人群中，过去12个月的大麻消费从2018年的19.3%显著增加到2019年合法化后的第一年（24.5%；p <.001），但此后保持稳定（2020年和2021年分别为24.3%和25.6%）。报告过去12个月使用过大麻的男性多于女性（28.4%对21.4%；p <.001）。相当数量的大麻消费者使用大麻是为了控制身体或心理健康状况。有针对性的信息传递可能对这个年龄组有益，包括与其他药物可能的相互作用。这项研究可能有助于为适合该年龄段的大麻教育提供信息。
