Use of khat in lactating women: a pilot study on breast-milk secretion

Nor-pseudoephedrine, one of the active ingredients of khat (Catha edulis), was found to be excreted in breast-milk in several lactating women who were chewing the leaves of the shrub according to the local customs. The compound could be traced in the urine of one breast-fed infant. It is concluded that the use of khat during lactation should be discouraged until further research has clearly elucidated the potential health hazards.
