Cannabis is a gateway drug that can lead to the engagement of other substances. Psychological dysfunctioning and dependence have been highlighted as primary components to substance misuse. The purpose of this study was to investigate what aspects of cannabis use and psychological dysfunctioning are associated with the engagement of other substances and impaired driving. Subject to screening, 200 active adult cannabis users completed an online survey. Existing data involving non-cannabis users (N = 833) were also implemented as comparative data. The comparisons suggested that cannabis users were far more likely to have used other drugs in the past 12 months, compared to non-cannabis users. Bivariate correlations and multiple regressions indicated that the degree of cannabis use and likely dependence, psycho-social motives for using cannabis, emotion dysregulation, and psychopathology were positively associated with the frequency of using and driving on other substances. Finally, an ANOVA demonstrated that outside of age, there were no apparent differences in substance use behaviours, motives for using cannabis, and psychological dysfunction, between medicinal and black-market cannabis users. These findings highlight the potential benefits of incorporating self-regulatory concepts into current road safety initiatives, which aim to reduce the interconnected issue of substance misuse and impaired driving behaviours.
大麻是一种导致其他物质滥用的“入门毒品”。心理功能障碍和依赖被强调为物质滥用的主要因素。本研究旨在调查大麻使用和心理功能障碍的哪些方面与其他物质的滥用和驾驶能力受损有关。在经过筛选后，200 名活跃的成年大麻使用者完成了在线调查。同时还采用了现有的非大麻使用者（N=833）的数据作为比较数据。比较结果表明，与非大麻使用者相比，大麻使用者在过去 12 个月中更有可能使用过其他毒品。双变量相关分析和多元回归分析表明，大麻使用的程度和可能的依赖、使用大麻的心理社会动机、情绪调节障碍和精神病理学与使用其他物质的频率和驾驶能力受损呈正相关。最后，方差分析表明，除了年龄之外，医用大麻和黑市大麻使用者在物质使用行为、使用大麻的动机和心理功能障碍方面没有明显差异。这些发现强调了将自我调节概念纳入当前道路安全倡议的潜在好处，这些倡议旨在减少物质滥用和驾驶能力受损行为的相互关联问题。
