English: Khat is a slow-growing shrub or tree that typically attains a height of 1–5 m (3 ft 3 in–16 ft 5 in). However, it can reach heights of up to 10 m (33 ft) in equatorial areas.The World Health Organization (WHO) classified it in 1980 as a drug of abuse that can produce psychological dependence, although the WHO does not consider khat addiction to be a serious problem. By contrast, the production, sale, and consumption are legal in the nations where its use is traditional of those cultures, including Djibouti, Kenya, Uganda, Ethiopia, Somalia and Yemen.
