The khat plant (Catha edulis) is produced in certain areas of East Africa and the Arabian peninsula, and the leaves are chewed for their stimulating effect. Fresh material, which is preferred by users, contains a substance that is rapidly converted to (+)-norpseudoephedrine. As a consequence of the traditional means of consumption, intoxication with khat is self-limiting but chronic consumption can cause certain disturbances to the health of the user and may also lead to social and economic damage to the individual and the community.
巧茶属植物（恰特草）生长于东非和阿拉伯半岛的某些地区，其叶子因具有刺激作用而被咀嚼。使用者更喜欢新鲜的材料，其中含有一种能迅速转化为（+）-去甲伪麻黄碱的物质。由于传统的食用方式，恰特草中毒具有自限性，但长期食用会对使用者的健康造成一定干扰，也可能给个人和社区带来社会和经济损害。
