In January 2020, the government of the Australian Capital Territory (ACT) decriminalised the possession and cultivation of cannabis for personal use. This study explored the driving-related attitudes, beliefs and behaviours of ACT residents who are legally cultivating and consuming cannabis.
A two-part cross-sectional study was conducted. Part-1: Cannabis users residing in the ACT were invited to complete an online survey. Part-2: Survey respondents who reported 'currently growing' cannabis were invited to submit a sample of their home-grown cannabis for phytocannabinoid analysis. Data from Parts 1 and 2 were used to estimate participants' usual Δ-tetrahydrocannabinol (THC) intakes.
N = 385 cannabis users completed all or part of the online survey and N = 52 submitted cannabis samples for phytocannabinoid analysis. Most participants (N = 224/330; 67.9%) reported waiting ≥7 h following cannabis use before driving. However, 21.5% (N = 71/330) reported waiting ≤3 h. These individuals had the highest cannabis and THC intakes of the sample (where known). Further analyses revealed that individuals who expressed less concern about roadside drug testing and the effects of non-medicinal and medicinal cannabis on driving, and who used cannabis more frequently, in larger amounts, and exclusively for non-medicinal purposes were more likely to report shorter 'wait times'.
A small proportion of cannabis users in the ACT appear to be driving shortly (i.e., ≤3 h) after consuming considerable quantities of cannabis and THC. This behaviour puts them at risk of driving while impaired and incurring legal sanctions. Interventions alerting these individuals to these possible risks are, therefore, warranted.
2020年1月，澳大利亚首都领地（ACT）政府将个人持有和种植大麻合法化。本研究探讨了在ACT合法种植和使用大麻的居民与驾驶相关的态度、信念和行为。
进行了一项分为两部分的横断面研究。第一部分：邀请居住在ACT的大麻使用者完成一项在线调查。第二部分：邀请报告“目前正在种植”大麻的调查受访者提交一份他们自家种植的大麻样本进行植物大麻素分析。来自第一部分和第二部分的数据用于估计参与者通常的Δ-四氢大麻酚（THC）摄入量。
N = 385名大麻使用者完成了全部或部分在线调查，N = 52人提交了大麻样本进行植物大麻素分析。大多数参与者（N = 224/330；67.9%）报告在使用大麻后等待≥7小时才开车。然而，21.5%（N = 71/330）的人报告等待时间≤3小时。在已知样本中，这些人的大麻和THC摄入量最高。进一步分析表明，那些对路边药物检测以及非药用和药用大麻对驾驶的影响不太担心，且更频繁、大量且仅用于非药用目的使用大麻的人，更有可能报告较短的“等待时间”。
ACT的一小部分大麻使用者在摄入大量大麻和THC后不久（即≤3小时）似乎就开车了。这种行为使他们面临驾驶时受损以及受到法律制裁的风险。因此，有必要采取干预措施，提醒这些人注意这些可能的风险。
