Khat, Catha edulis, is a flowering evergreen shrub cultivated in East Africa and the South-West Arabian Peninsula. The principle active constituents of khat are cathinone (ß-ketoamphetamine) and cathine (norpseudoephedrine), both central nervous system (CNS) stimulants. Chewing khat leaves releases these substances into the oral fluid.

Cathinone has a similar chemical structure to amphetamine and although less potent shares similar chemical and physical properties. Cathinone is very unstable and decomposes to the less potent ingredient cathine as the leaves dry. The taste and potency of the freshly picked leaves is lost within 24–36 hours.



Khat is most commonly chewed over several hours but it can also be brewed as a tea.
