Catha, commonly known as khat, is a flowering plant native to the Horn of Africa and the Arabian Peninsula. Its leaves contain stimulant compounds, primarily cathinone and cathine, which can produce effects similar to those of amphetamines when chewed or brewed as tea. The plant has been used for centuries in traditional practices and social gatherings. In many cultures, particularly in Yemen and Somalia, chewing Catha leaves is a common social activity. While it is legal in some countries, it is classified as a controlled substance in others due to its potential for abuse and health risks. Regular use can lead to dependence and various health issues.
