Ali Abdi, 14, and his friend Abdulahi Yaroow, 13, chew khat in Mogadishu August 10, 2014. Grown on plantations in the highlands of Kenya and Ethiopia, tonnes of khat, or qat, dubbed "the flower of paradise" by its users, are flown daily into Mogadishu airport, to be distributed from there in convoys of lorries to markets across Somalia. Britain, whose large ethnic Somali community sustained a lucrative demand for the leaves, banned khat from July as an illegal drug. This prohibition jolted the khat market, creating a supply glut in Somalia and pushing down prices, to the delight of the many connoisseurs of its amphetamine-like high.

People dance at a nightclub in Baghdad in this July 9, 2009 file photo. Recent efforts by authorities, clergy and unknown bands of neighbourhood enforcers to police morals by shutting nightclubs, bars and other establishments has heightened concerns among academics and intellectuals that Iraq, now emerging from war, is displaying the tendencies of a hard-line Islamic state. Baghdad's local government this month re-activated a federal order from last year to close down the capital's nightclubs and liquor shops due to concern the venues were undermining morals. Last week, anti-American Shi'ite cleric Moqtada al-Sadr issued a strongly worded statement calling for Iraqis to take a stand against "corruption, intoxication and addiction."
