An alkaloid compound found in khat leaves (Catha edulis), related to cathine and used as a stimulant.
From khat (the plant name) combined with chemical suffix -idine. This is a specialized chemical/botanical term from 19th-20th century pharmacology.
Cathidine and cathine are the stimulating compounds in khat leaves—they're chemically similar to amphetamines, which is why people chew khat for the same reasons coffee drinkers drink coffee!
