This study analysed dangerous driving behaviours in twenty young occasional cannabis users through objective and self-reported data, studying the relationship between the two aspects. Visual function was assessed in a baseline session and after smoking cannabis, as well as speed-related behaviour in a driving simulator. The participants responded to questionnaires on sociodemographic factors, their consumption profile, and the incidence of dangerous behaviours (Dula Dangerous Driving Index; DDDI). After cannabis use, the results revealed a significant deterioration in visual function. In terms of speed management, they showed significantly greater acceleration force in the two different sections of the route, and they drove significantly faster. Our correlations indicate that males and heavier users display more risky speed management. Likewise, the heavier cannabis users admitted to increased dangerous driving behaviour, and an accident in the preceding year was associated with a trend towards aggressive driving behaviour according to the DDDI questionnaire. The findings of this study suggest that cannabis users adopt dangerous behaviours when driving, despite the effect this drug has on certain important functions, such as vision. The results suggest a need for awareness-raising and information campaigns.
本研究通过客观和自我报告的数据，分析了 20 名偶尔吸食大麻的年轻人的危险驾驶行为，并研究了这两个方面之间的关系。在基线测试中以及吸食大麻后，研究人员评估了参与者的视觉功能，并在驾驶模拟器中测试了与速度相关的行为。参与者回答了有关社会人口因素、消费情况以及危险行为（Dula 危险驾驶指数；DDDI）发生率的问卷。吸食大麻后，结果显示视觉功能明显恶化。在速度管理方面，他们在路线的两个不同路段表现出明显更大的加速度力，并且驾驶速度明显更快。我们的相关性表明，男性和重度使用者表现出更危险的速度管理。同样，较重的大麻使用者承认危险驾驶行为增加，而前一年的事故与根据 DDDI 问卷显示的攻击性驾驶行为趋势有关。本研究结果表明，尽管大麻会影响某些重要功能，如视力，但大麻使用者在驾驶时仍会采取危险行为。结果表明需要提高认识和开展宣传活动。
