最近的研究表明，经常使用某些药物，如烟草和酒精，与处理与药物有关的线索的偏见有关，因为这些线索会吸引注意力，引起接近，并被认为是愉快的。这项研究调查了经常吸食大麻的人是否对大麻相关的图片线索表现出类似的认知偏差。23名大麻吸食者和23名非大麻吸食者分别完成了一系列任务，包括眼球运动监测的视觉探测任务（测量注意偏差）、刺激-反应相容性任务（测量内隐接近偏差）和效价评定任务（测量大麻线索的感知愉悦性）。结果表明，相对于66吸食者，常规吸食者倾向于保持对大麻线索的注视，对大麻线索做出更快的接近反应，并将大麻线索评价为令人愉快的。研究结果与先前吸烟者和重度饮酒者的研究结果基本一致，并讨论了成瘾的激励动机理论的含义。2006爱思唯尔爱尔兰有限公司版权所有。
Recent studies indicate that the regular use of certain drugs, such as tobacco and alcohol, is associated with biases in the processing of drug-related cues, as those cues grab attention, elicit approach and are perceived as pleasant. This study investigated whether regular cannabis users exhibit comparable cognitive biases for cannabis-related pictorial cues. Twenty-three regular cannabis users and 23 non-user controls completed a series of tasks including a visual probe task with concurrent eye movement monitoring (to measure attentional bias), a stimulus-response compatibility task (to measure implicit approach bias) and a valence rating task (to measure the perceived pleasantness of cannabis cues). Results indicated that, relative to 66-users, regular cannabis users had biases to maintain their gaze on cannabis cues, to make faster approach responses towards cannabis cues, and to rate cannabis cues as pleasant. Results are generally consistent with previous findings from tobacco smokers and heavy drinkers, and the implications for incentive-motivational theories of addiction ate discussed.
