OBJECTIVES
We investigated trends in cannabis-related hospitalizations among youth before and after legalization of recreational cannabis in Canada on October 17, 2018.
METHODS
We computed rates of cannabis-related hospitalizations and the proportion of substance-related hospitalizations involving cannabis by age and sex in the months before and after legalization in Quebec, Canada.
RESULTS
In boys aged 10 to 14 years, cannabis-related hospitalization rates increased from 5.2 per 100,000 one year before legalization [95% confidence interval (CI) 2.9-9.3] to 9.5 per 100,000 after legalization (95% CI 6.2-14.6), although the increase was not statistically significant. Cannabis was reported in 39.3% of substance-related hospitalizations in boys aged 10 to 14 years before legalization, compared with 70.0% after legalization, representing a difference of 30.7% (95% CI 2.8-58.6). There was no increase in cannabis-related hospitalizations among girls or boys aged 15 to 19 years.
CONCLUSIONS
This study suggests that cannabis legalization in Canada did not increase the risk of short-term cannabis-related hospitalization among girls and older boys. However, legalization may have contributed to an increase in the risk in boys under 15 years. Further data are needed to clarify trends after legalization for younger adolescents.
目的
我们调查了 2018 年 10 月 17 日加拿大休闲大麻合法化前后，青少年与大麻相关的住院治疗趋势。
方法
我们计算了加拿大魁北克省大麻合法化前后，按年龄和性别划分的与大麻相关的住院率和涉及大麻的物质相关住院率的比例。
结果
在 10 至 14 岁的男孩中，大麻相关住院率从合法化前一年的每 10 万人 5.2 例（95%置信区间：2.9-9.3）上升至合法化后的每 10 万人 9.5 例（95%置信区间：6.2-14.6），尽管这一增长没有统计学意义。在大麻合法化前，10 至 14 岁的男孩中有 39.3%的物质相关住院治疗涉及大麻，而在大麻合法化后，这一比例上升至 70.0%，相差 30.7%（95%置信区间：2.8-58.6）。在 15 至 19 岁的女孩和男孩中，与大麻相关的住院治疗并没有增加。
结论
本研究表明，加拿大的大麻合法化并没有增加女孩和年龄较大男孩短期与大麻相关的住院治疗风险。然而，合法化可能导致 15 岁以下男孩的风险增加。需要进一步的数据来阐明合法化后青少年的趋势。
