Cannabis is the most extensively abused drug, leading to multiple health burdens such as traffic accidents and psychosis. There is a global wave of legalization of recreational and medical cannabis. This study aimed to understand future healthcare workers' intention to use cannabis through extended Theory of Planned Behavior (TPB). An online cross-sectional survey on cannabis, including validated survey tools and questions on demographics, knowledge, and constructs of the TPB was designed, and distributed during virtual classes in late 2020. Responses were obtained from the Faculty of Medicine of a local university. Nine hundred ninety-six responses were collected, of which 629 were complete and analysed. Age was the only demographic variable associated with cannabis use intention ( = 0.029). Respondents with intention had better knowledge of cannabis. All TPB and additional constructs, including perceived behavioral control (COR = 3.44, 95% CI 2.72-4.35, < 0.001), descriptive norm (COR = 2.24, 95% CI 1.81-2.77, < 0.001), injunctive norm (COR = 0.51, 95% CI 0.42-0.61, < 0.001), attitude (COR = 1.23, 95% CI 1.18-1.28, < 0.001), knowledge (COR = 1.08, 95% CI 1.03-1.14), and perceived availability (COR = 2.75, 95% CI 2.22-3.40, < 0.001) were individually associated with intention. In the final multiple logistic regression model adjusted for age, only attitude (AOR = 1.19, 95% CI 1.13-1.25, < 0.001) and perceived availability ( = 0.004) showed statistically significant associations with intention. Descriptive norm (standardized coefficient = 0.570) had better explanatory power than the injunctive norm (standardized coefficient = -0.143) in the model. Perceived behavioral control was associated with intention among respondents with negative to neutral attitudes towards cannabis (AOR = 2.48, 95% CI 1.63-3.77, < 0.001), but not among those with positive attitudes. All TPB constructs positively correlated with the intention to use cannabis. Changing the attitudes and perceived control on cannabis use may be useful in preventing cannabis use.
大麻是滥用最广泛的毒品，会导致交通事故和精神病等多种健康负担。全球范围内正在掀起娱乐和医用大麻合法化的浪潮。本研究旨在通过扩展计划行为理论（TPB）了解未来医疗保健工作者使用大麻的意愿。这是一项关于大麻的在线横断面调查，包括经过验证的调查工具以及关于人口统计学、知识和 TPB 结构的问题，于 2020 年末在虚拟课程中进行了分发。该调查收到了当地一所大学医学院的回应。共收集了 996 份回复，其中 629 份完整并进行了分析。年龄是唯一与大麻使用意愿相关的人口统计学变量（ = 0.029）。有使用意向的受访者对大麻的了解更好。所有 TPB 和其他结构，包括感知行为控制（COR = 3.44，95%CI 2.72-4.35， < 0.001）、描述性规范（COR = 2.24，95%CI 1.81-2.77， < 0.001）、规范性规范（COR = 0.51，95%CI 0.42-0.61， < 0.001）、态度（COR = 1.23，95%CI 1.18-1.28， < 0.001）、知识（COR = 1.08，95%CI 1.03-1.14）和感知可用性（COR = 2.75，95%CI 2.22-3.40， < 0.001）均与意愿独立相关。在调整年龄的最终多变量逻辑回归模型中，只有态度（AOR = 1.19，95%CI 1.13-1.25， < 0.001）和感知可用性（ = 0.004）与意愿呈统计学显著相关。描述性规范（标准化系数 = 0.570）在模型中的解释力优于规范性规范（标准化系数 = -0.143）。在对大麻持消极和中性态度的受访者中（AOR = 2.48，95%CI 1.63-3.77， < 0.001），感知行为控制与使用大麻的意愿相关，但在对大麻持积极态度的受访者中没有相关性。所有 TPB 结构与使用大麻的意愿呈正相关。改变对大麻使用的态度和感知控制可能有助于预防大麻使用。
