Catha edulis is a flowering plant that is native to East Africa and the Arabian Peninsula. It is commonly referred to as khat or quaadka in the Somali language, tschat in Ethiopia, and miraa in Kenya. Other synonyms for Catha edulis include Abyssinian tea, Arabian tea, and Somali tea. The plant contains a stimulant called cathinone, which is similar to amphetamines and can create a feeling of euphoria when chewed or consumed in other ways. While it is often used socially or for medicinal purposes, khat is considered a controlled substance in many countries due to its potential for addiction and negative health effects.
