OBJECTIVE
To investigate the prevalence of therapeutic cannabis use within a general population sample of adults and to describe various characteristics associated with use.
METHODS
Data were derived from the 2013 and 2014 CAMH Monitor Survey of adults in Ontario, Canada. This repeated cross-sectional survey employed a regionally stratified design and utilized computer-assisted telephone interviewing. Analyses were based on 401 respondents who reported using cannabis.
RESULTS
The data indicated that 28.8% of those who used cannabis in the past year self-reported using cannabis for therapeutic purposes. Of therapeutic users, 15.2% reported having medical approval to use cannabis for therapeutic purposes. Cannabis use for therapeutic purposes was associated with more frequent use of cannabis, a moderate to high risk of problematic cannabis use, and a greater likelihood of using prescription opioids for medical purposes. There was little difference in cannabis use for therapeutic purposes according to sex, age, and marital status after adjusting for opioid use and problematic cannabis use.
CONCLUSION
Findings suggest some potential negative consequences of cannabis use for therapeutic purposes; however, further research is needed to better understand the range and patterns of use and their corresponding vulnerabilities.
目的
调查成年普通人群样本中使用治疗性大麻的流行情况，并描述与使用相关的各种特征。
方法
数据来源于2013年和2014年对加拿大安大略省成年人进行的加拿大成瘾与心理健康中心监测调查。这项重复的横断面调查采用区域分层设计，并利用计算机辅助电话访谈。分析基于401名报告使用过大麻的受访者。
结果
数据表明，在过去一年中使用大麻的人群中，28.8%的人自我报告使用大麻用于治疗目的。在治疗性使用者中，15.2%的人报告有医疗许可使用大麻用于治疗目的。用于治疗目的的大麻使用与更频繁地使用大麻、大麻使用问题的中度至高度风险以及出于医疗目的使用处方阿片类药物的更大可能性相关。在调整阿片类药物使用和大麻使用问题后，按性别、年龄和婚姻状况划分，用于治疗目的的大麻使用几乎没有差异。
结论
研究结果表明大麻用于治疗目的存在一些潜在的负面后果；然而，需要进一步研究以更好地了解使用范围和模式及其相应的易感性。
