The leaves of the shrub Catha edulis (khat) are widely chewed as part of social life in several countries around the Red Sea and in East Africa. The leaves possess stimulant properties and are also used by pregnant women. The effect of khat on birth-weight has been studied, It was found that healthy full-term, singletons, born after uneventful pregnancies and deliveries, had a significantly lower average birth-weight when the mothers were khat-chewers, either habitually or occasionally (P less than 0.001). Khat-chewing appears to be one of several maternal practices adverse to the fetus.
巧茶属灌木（巧茶）的叶子在红海周边的几个国家以及东非是社交生活的一部分，人们广泛咀嚼它。这些叶子具有刺激特性，孕妇也会使用。已经对巧茶对出生体重的影响进行了研究，结果发现，在妊娠和分娩过程顺利的情况下出生的健康足月单胎婴儿，其母亲无论是习惯性还是偶尔咀嚼巧茶，婴儿的平均出生体重都显著较低（P小于0.001）。咀嚼巧茶似乎是对胎儿不利的几种母体行为之一。
