Khat (Catha edulis) is a widely used stimulating drug often consumed in daily routine in Yemen and East African countries. Chewing khat acutely elicits states of euphoria and feelings of well-being which later shift into emotional instability and low mood. Little is known about emotional regulation in habitual khat chewers. In this study, we compared self-reports on trait anger as well as positive and negative affect responses to a mental arithmetic challenge. Participants included 135 men and women from Yemen who chew khat regularly, occasionally or not at all. Participants attended a laboratory session that involved resting periods and performing a math challenge. Analyses of variance and regression show that regular khat chewing is associated with higher trait anger, more pronounced negative responses during stress and less pronounced positive emotional states. These results suggest that regular khat chewing is associated with disturbances in emotion regulation processes.
阿拉伯茶（Catha edulis）是一种被广泛使用的兴奋剂，在也门和东非国家，人们经常将其作为日常消遣的一部分。咀嚼阿拉伯茶会使人迅速产生欣快感和幸福感，随后会转变为情绪不稳定和情绪低落。目前对于习惯性咀嚼阿拉伯茶者的情绪调节知之甚少。在这项研究中，我们比较了习惯性咀嚼阿拉伯茶者的特质愤怒报告，以及他们对心理算术挑战的积极和消极情绪反应。参与者包括来自也门的 135 名男性和女性，他们有规律地、偶尔地或根本不咀嚼阿拉伯茶。参与者参加了一个实验室会议，包括休息时间和进行数学挑战。方差分析和回归分析表明，有规律地咀嚼阿拉伯茶与较高的特质愤怒、在压力下更明显的负面反应以及不那么明显的积极情绪状态有关。这些结果表明，有规律地咀嚼阿拉伯茶与情绪调节过程的紊乱有关。
