Catha edulis (Khat, qat, or "edible kat"[1]) is a flowering plant that is native to the Horn of Africa and the Arabian Peninsula. Among communities from these areas, khat chewing has a history as a social custom dating back thousands of years.[2]

Khat contains a monoamine alkaloid called cathinone, an amphetamine-like stimulant, which is said to cause excitement, loss of appetite, and euphoria. In 1980, the World Health Organization (WHO) classified it as a drug of abuse that can produce mild-to-moderate psychological dependence (less than tobacco or alcohol),[3] although WHO does not consider khat to be seriously addictive.[2] The plant has been targeted by anti-drug organisations such as the DEA.[4] It is a controlled substance in some countries, such as the United States, Canada and Germany, while its production, sale and consumption are legal in other nations, including Djibouti, Somalia, Ethiopia and Yemen.[5]
