There have been suggestions of hypofrontality in cannabis users. To understand cannabis-related differences in decisional processes, Janis and Mann's conflict model of decision making was applied to recreational cannabis smokers who varied in their alcohol use and level of psychological distress.
An online sample of recreational substance users (114 male, 119 female) completed the Melbourne Decision Making Questionnaire, the Alcohol Use Disorders Identification Test (AUDIT), Kessler's Psychological Distress Scale (K10), and the Severity of Dependence Scale (SDS) for cannabis.
Multivariate analysis of variance examined self-reported decision-making styles as a function of gender, recent cannabis use, risky alcohol consumption, and levels of psychological distress. Psychological distress was associated with lower decisional self-esteem and higher levels of procrastination and buck-passing. There were gender differences associated with cannabis use. Female cannabis users reported higher levels of hypervigilance, while male cannabis users reported lower levels of buck-passing.
Although there was little indication of an avoidant decisional style in cannabis users, the results suggest that cannabis affects decisional processes, contributing to panic in females and impulsivity in males.
有观点认为大麻使用者存在额叶功能低下的情况。为了解与大麻相关的决策过程差异，将詹尼斯和曼恩的决策冲突模型应用于在饮酒量和心理困扰程度方面存在差异的消遣性大麻吸食者。
一个消遣性物质使用者的在线样本（114名男性，119名女性）完成了墨尔本决策问卷、酒精使用障碍识别测试（AUDIT）、凯斯勒心理困扰量表（K10）以及大麻依赖严重程度量表（SDS）。
多变量方差分析考察了自我报告的决策风格与性别、近期大麻使用情况、危险饮酒量以及心理困扰程度之间的关系。心理困扰与较低的决策自尊以及较高的拖延和推诿水平相关。大麻使用存在性别差异。女性大麻使用者报告的过度警觉水平较高，而男性大麻使用者报告的推诿水平较低。
尽管几乎没有迹象表明大麻使用者存在回避型决策风格，但结果表明大麻会影响决策过程，导致女性出现恐慌和男性出现冲动行为。
