Using cannabis (e.g., smoking marijuana) is becoming popular, partly due to a legalization trend across different countries. This tendency has resulted in cannabis consumption being accepted by society as if it were harmless. However, evidence shows that the use of this drug has detrimental effects on cognitive, academic, and professional performance, which tend to be larger in younger users (e.g., high school students). In this review article, we focus on the decline of visuospatial processing associated with cannabis consumption in nondependent or nonclinical high school students. We start by providing evidence of the pivotal role of visuospatial processing for learning. Next, we review experimental and correlational evidence of declines in visuospatial processing related to cannabis use. Three types of correlational studies are considered: (a) comparisons of declines between visuospatial processing and other cognitive tasks, (b) studies comparing declines between high school students and adult participants, and (c) stringent correlational studies (e.g., large samples, longitudinal data, twin studies). We also include evidence in abstinent cannabis conditions. We conclude that using cannabis may moderately impair visuospatial processing and learning in nondependent high school students, although the effects could disappear under abstinence and tend to be lower than on other cognitive functions. Instructional implications for educators and future research directions are discussed.

使用大麻（例如，抽大麻）正变得流行，部分原因是不同国家之间的合法化趋势。这种趋势导致大麻消费被社会接受，就好像是无害的。但是，有证据表明，使用这种药物会对认知，学术和专业表现产生有害影响，而在年轻用户（例如高中生）中这种影响往往更大。在这篇评论文章中，我们重点关注非独立或非临床高中学生与大麻消费相关的视觉空间加工的下降。我们首先提供视觉空间处理对于学习的关键作用的证据。接下来，我们回顾与大麻使用相关的视觉空间加工下降的实验和相关证据。考虑了三种类型的相关性研究：（a）视觉空间处理与其他认知任务之间的下降比较，（b）比较高中生与成年参与者之间下降的研究，以及（c）严格的相关研究（例如，大样本，纵向数据，双胞胎研究）。我们还包括禁酒条件下的证据。我们得出的结论是，使用大麻可能会中等程度地削弱非依赖型高中生的视觉空间加工和学习能力，尽管这种影响在禁欲状态下可能会消失并且趋于低于其他认知功能。讨论了对教育工作者的指导意义和未来的研究方向。（c）严格的相关研究（例如，大样本，纵向数据，孪生研究）。我们还包括禁酒条件下的证据。我们得出的结论是，使用大麻可能会中等程度地削弱非依赖型高中生的视觉空间加工和学习能力，尽管这种影响在禁欲状态下可能会消失并且趋于低于其他认知功能。讨论了对教育工作者的指导意义和未来的研究方向。（c）严格的相关研究（例如，大样本，纵向数据，孪生研究）。我们还包括禁酒条件下的证据。我们得出的结论是，使用大麻可能会中等程度地削弱非依赖型高中生的视觉空间加工和学习能力，尽管这种影响在禁欲状态下可能会消失并且趋于低于其他认知功能。讨论了对教育工作者的指导意义和未来的研究方向。
