The subjective effects of Khat (Catha edulis) chewing were studied in 14 male somali, habitual khat users, by means of the Addiction Research Center Inventory (ARCI) questionnaire and of visual analogue scales concerning mood and appetite. Results show that euphoria, improved intellectual efficiency and alertness were associated with khat consumption in 10 subjects. In contrast, the remaining 4 subjects experienced only dysphoria and mild sedation. These latter effects were present in all the subjects in the post-chewing period. In spite of these subjective differences, blood pressure and pulse rate increased in all the volunteers studied. As a whole, these results are consistent with the presumed amphetamine-like action of khat, but suggest also a major role of environmental factors in the expression of these actions.
通过成瘾研究中心量表（ARCI）问卷以及关于情绪和食欲的视觉模拟量表，对14名习惯性咀嚼巧茶（Catha edulis）的索马里男性进行了咀嚼巧茶的主观效应研究。结果显示，10名受试者咀嚼巧茶后出现了欣快感、智力效率提高和警觉性增强。相比之下，其余4名受试者仅出现烦躁不安和轻度镇静。在咀嚼后的时间段内，所有受试者都出现了后一种效应。尽管存在这些主观差异，但所有接受研究的志愿者的血压和脉搏率均有所升高。总体而言，这些结果与巧茶具有类似苯丙胺作用的推测一致，但也表明环境因素在这些作用的表现中起主要作用。
