There appears to be a significant positive relation between problematic cannabis use and problem gambling behaviors. Recent reviews have noted that individuals who use cannabis more frequently may experience less acute executive functioning impairment than those who use cannabis less often. The current study explored the relation between cannabis use frequency and problem gambling outcomes in those who gamble under the influence of cannabis, to explore if increased cannabis use frequency increases reported gambling problems, or is the reported effect on their gambling behavior is lessened in individuals who consume cannabis regularly? 769 individuals who gambled at least weekly were recruited from a crowdsource platform. These individuals reported their gambling behavior and cannabis use. To explore the relation between cannabis use frequency and problem gambling severity, regression models following both a simple linear model and a quadratic model were generated and evaluated for model fit and significance. The quadratic model was found to best fit the relation between cannabis use frequency and problem gambling severity. The quadratic model was also found to best fit the relation between frequency of time spent gambling under the influence of cannabis and problem gambling severity. Those who consumed cannabis infrequently or very frequently reported fewer gambling problems overall compared to those who consumed cannabis at a moderate frequency. The acute relation between cannabis use and gambling may be more complex than simply amplifying problematic gambling behaviors.
问题性大麻使用与问题赌博行为之间似乎存在显著的正相关关系。最近的综述指出，与较少使用大麻的人相比，更频繁使用大麻的人可能经历的急性执行功能损害更少。本研究探讨了在大麻影响下赌博的人群中，大麻使用频率与问题赌博结果之间的关系，以探究大麻使用频率的增加是否会导致报告的赌博问题增加，或者对于经常使用大麻的个体，其对赌博行为的报告影响是否会减轻？从一个众包平台招募了769名至少每周赌博一次的个体。这些个体报告了他们的赌博行为和大麻使用情况。为了探究大麻使用频率与问题赌博严重程度之间的关系，生成了遵循简单线性模型和二次模型的回归模型，并对模型拟合度和显著性进行了评估。发现二次模型最能拟合大麻使用频率与问题赌博严重程度之间的关系。还发现二次模型最能拟合在大麻影响下花费在赌博上的时间频率与问题赌博严重程度之间的关系。与中等频率使用大麻的人相比，很少或非常频繁使用大麻的人总体上报告的赌博问题较少。大麻使用与赌博之间的急性关系可能比简单地放大问题性赌博行为更为复杂。
