With the majority of US states having adopted legislation to medically and/or recreationally legalize cannabis, public perception of the drug is now overwhelmingly favorable. Increased access and prevalence of use are accompanied by perceptions of low health risk and/or of therapeutic benefits associated with cannabis use. Aside from evidence for symptom relief in certain medical conditions, evidence regarding therapeutic effects of cannabis for many conditions remains elusive, leaving the decision regarding when and how to use cannabis to the user. Both therapeutic and recreational reasons (motives) for CU are largely shaped through exposure to messages about the effects of cannabis, yet little is known about the source of messaging, how it is transmitted to users, how it shapes their thinking, and ultimately its association with CU patterns. The proposed study will gather critical information about message sources, cannabis-promoting content, and risk warnings being disseminated to cannabis users as well as the messages being received, their effects on CU motives, and subsequent CU. The mixed-methods design will include two phases. Phase 1 involves semi-structured interviews conducted with 1) cannabis users, as well as with message sources, including 2) cannabis dispensary and retail outlet staff (budtenders), 3) growers, and 4) health care providers who discuss cannabis with patients. Additionally, extraction and coding of messaging content will be conducted across internet and social media messaging platforms. Observational coding of recreational/medical cannabis outlets will be conducted using validated surveillance tools. Together, these data permit characterization of cannabis messaging content across various types of sources and platforms (Aim 1) that will in turn inform Phase 2 methods. Phase 2 consists of a three-burst 4-week ecological momentary assessment (EMA) study with a sample (N=300) of weekly 18-74 year-old cannabis users. Participants will complete brief smartphone-based measures of exposure to messaging (source and content), cannabis motives, and use patterns in the natural environment. With these quantitative data, this will be the first study to examine prospective associations between a user’s exposure to cannabis messaging and motives and other cognitions (Aim 2). Further, we will test whether cannabis motives are a mechanism underlying the association between cannabis messaging and CU at both the between-person and within-person levels (Aim 3). Finally, we will explore user characteristics and message source characteristics as potential moderators of the effects of cannabis messaging and CU (Aim 4). This combination of complementary and highly rigorous data collection approaches will provide the most nuanced understanding of the messages being disseminated about the effects of cannabis to the cannabis user. Findings will arm policy makers and cannabis regulatory science with evidence-based information about the impact of cannabis messaging that can ultimately reduce potential harms from misuse.

美国大多数州已通过立法将大麻在医疗和/或娱乐方面合法化， 现在公众对这种药物的看法是非常有利的，其使用率和使用率都在提高。 伴随着与大麻使用相关的低健康风险和/或治疗益处的看法。 除了某些医疗状况下症状缓解的证据外，有关以下药物治疗效果的证据 在许多情况下使用大麻仍然难以捉摸，因此需要决定何时以及如何使用大麻 对用户来说，CU 的治疗和娱乐原因（动机）很大程度上是通过接触来形成的。 关于大麻影响的信息，但人们对信息的来源和传播方式知之甚少 所提出的研究将如何影响用户的思维，以及最终与 CU 模式的关联。 收集有关消息来源、大麻促销内容和风险警告的重要信息 向大麻使用者传播的信息以及收到的信息、它们对 CU 动机的影响，以及 后续的 CU 混合方法设计将包括两个阶段：半结构化。 对 1) 大麻使用者以及消息来源进行的采访，包括 2) 大麻 药房和零售店工作人员（budtender）、3）种植者和 4）讨论大麻的医疗保健提供者 此外，将通过互联网和患者对消息内容进行提取和编码。 娱乐/医疗大麻商店的观察编码将是 这些数据共同使用经过验证的监测工具进行分析。 跨各种类型的来源和平台的消息传递内容（目标 1），这反过来又将为阶段 2 提供信息 第 2 阶段包括为期 4 周的三爆发式生态瞬时评估 (EMA) 研究，其中包括 每周 18-74 岁大麻使用者的样本（N = 300）参与者将完成基于智能手机的简短调查。 接触信息（来源和内容）、大麻动机和自然使用模式的措施 有了这些定量数据，这将是第一项研究前瞻性关联的研究。 用户接触大麻信息、动机和其他认知之间的关系（目标 2）。 测试大麻动机是否是大麻信息传递与大麻之间关联的潜在机制 人与人之间和人内部层面的 CU（目标 3）最后，我们将探索用户特征。 和消息来源特征作为大麻消息和 CU 影响的潜在调节因素 （目标 4）。这种互补和高度严格的数据收集方法的结合将提供 对所传播的有关大麻对人类影响的信息有最细致的了解 调查结果将为政策制定者和大麻监管科学提供基于证据的支持。 有关大麻信息传递影响的信息，最终可以减少滥用造成的潜在危害。
