Thirty states now have medical marijuana laws (MML), 9 have recreational marijuana laws (RML), and many more states are considering such laws. The health effects of cannabis laws are controversial; understanding them is a major public health and NIDA priority (PA-17-135). Thus far, only 3 studies of adults (2 of them ours; Hasin et al., 2017, Martins et al., 2016) used multi-level modeling to examine MML effects on cannabis outcomes with individual data. These studies suggested post-MML increases in cannabis use and Cannabis Use Disorder (CUD). However, they left many questions unanswered, including whether MML have stronger effects in those with key vulnerability factors (chronic pain, psychiatric disorders). In addition, soaring rates of opioid prescriptions and overdoses have led to calls for MML as part of the solution to the US opioid crisis, but most MML-opioid studies are ecological (a weak design to study individual behavior), and results from individual-level studies leave the evidence unclear. Ecological studies also suggest that through cannabis substitution, MML reduce medication prescriptions for common psychiatric disorders (e.g., PTSD, depression), but no individual-level studies of this have been conducted. Importantly, RML effects are almost entirely unknown, a major gap in knowledge. In Veterans Administration (VA) patients, CUD prevalence has doubled since 2002, and in those age ≥35, is 2-6 times higher than in the general population. VA patients also have high rates of opioid prescriptions, overdoses, and of chronic pain and psychiatric disorders that may increase their vulnerability to adverse MML and RML effects. They thus are a large, vulnerable population in whom MML and RML effects are unknown. We will investigate MML and RML effects utilizing a major resource, the individual data from the VA Electronic Medical Record, available since 2000 from the ~5,000,000 patients served each year by the VA healthcare system. We will create yearly EMR datasets, and merge this with National Death Index data, Medicare data (for those age ≥65) and state-year MML and RML variables that we will create. Using multi-level models and difference-in-difference tests, we will examine MML and RML effects on three main outcomes: cannabis (use, CUD), opioids (prescriptions, fatal and non-fatal overdoses, opioid use disorders), and psychotropic medication prescriptions (antidepressants, anxiolytics, sedatives/hypnotics). Importantly, we will determine if pain, psychiatric disorders or demographics (sex, age, race/ethnicity) modify MML/RML effects. We will also examine specific MML/RML provisions, time lags, and breakpoints in trends reflecting federal policy changes. Analyses will incorporate individual- and state-level confounders, e.g., state norms, economic factors. We will also explore alcohol and tobacco outcomes. The research team includes substance epidemiology/policy experts and VA addiction and internal medicine experts. Findings will be disseminated to clinicians and policy-makers. Determining MML/RML effects in VA patients will make a major contribution to the limited adult literature on MML/RML, contributing to knowledge that will inform policy and the care of individuals with vulnerability factors.

30个州现在有医用大麻法（MML），9个州有娱乐性大麻法（RML），许多州都有大麻法。 更多的国家正在考虑制定此类法律。大麻法律对健康的影响是有争议的;理解 他们是一个主要的公共卫生和NIDA的优先事项（PA-17-135）。到目前为止，只有3项成人研究（其中2项是我们的; Hasin等人，2017年，Martins等人，2016）使用多层次建模来检查MML对大麻结果的影响 个人数据。这些研究表明，MML后大麻使用和大麻使用障碍增加 （CUD）。然而，他们留下了许多问题没有回答，包括MML是否在那些 关键的脆弱性因素（慢性疼痛，精神疾病）。此外，阿片类药物处方率飙升 和过量导致呼吁MML作为解决美国阿片类药物危机的一部分，但大多数MML-阿片类药物 研究是生态学的（研究个体行为的弱设计），个人水平的研究结果离开了 证据不清楚。生态研究还表明，通过大麻替代，MML减少了 常见精神疾病的药物处方（例如，创伤后应激障碍，抑郁症），但没有个人水平 对此进行了研究。重要的是，RML效应几乎是完全未知的，这是研究的一个主要空白。 知识在退伍军人管理局（VA）患者中，CUD患病率自2002年以来翻了一番， 年龄≥35岁，是一般人群的2-6倍。VA患者的阿片类药物使用率也很高 处方，过量，慢性疼痛和精神疾病，可能会增加他们的脆弱性， 不良MML和RML效应。因此，他们是一个庞大的弱势群体，MML和RML的影响是 未知我们将调查MML和RML的影响，利用一个主要的资源，从VA的个人数据 电子病历，自2000年以来可从VA每年服务的约5，000，000名患者中获得 医疗保健系统。我们将创建年度EMR数据集，并将其与国家死亡指数数据，医疗保险数据， 数据（年龄≥65岁）和我们将创建的州年MML和RML变量。使用多层次模型 和差异中的差异测试，我们将研究MML和RML对三个主要结果的影响：大麻 (use、CUD）、阿片类药物（处方药、致命和非致命过量、阿片类药物使用障碍）和精神药物 药物处方（抗抑郁药、抗焦虑药、镇静剂/催眠药）。重要的是，我们将确定， 疼痛、精神疾病或人口统计学（性别、年龄、人种/种族）改变MML/RML效应。我们还将 检查具体的MML/RML规定，时间滞后和反映联邦政策变化的趋势断点。 分析将纳入个人和国家水平的混杂因素，例如，国家规范经济因素我们将 也探讨酒精和烟草的结果。研究小组包括物质流行病学/政策专家 以及退伍军人事务部的戒毒专家和内科专家调查结果将分发给临床医生和政策制定者。 确定VA患者中的MML/RML效应将对关于VA的有限成人文献做出重大贡献。 MML/RML，有助于为政策和对具有脆弱性因素的个人的护理提供信息。
