, which are long and broad. It takes seven to eight years for the khat plant to reach its full height. Other than access to sun and water, khat requires little maintenance. Ground water is often pumped from deep wells by diesel engines to irrigate the crops, or brought in by water trucks. The plants are watered heavily starting around a month before they are harvested to make the leaves and stems soft and moist. A good khat plant can be harvested four times a year, providing a year-long source of income for the farmer. The shrub's flowers are produced on short axillary cymes that are in length. Each flower is small, with five white petals. The

. There, chewing khat predates the use of coffee and is used in a similar social context. Its fresh leaves and tops are chewed or, less frequently, dried and consumed as tea, to achieve a state of euphoria and stimulation. The leaves or the soft part of the stem can be chewed with either chewing gum or fried peanuts to make it easier to chew. In

estimate, khat accounted for 30% of Yemen's economy. In countries outside the core area of growth and consumption, khat is sometimes chewed at parties or social functions. It may also be used by farmers and labourers for reducing physical fatigue or hunger, and by drivers and students for improving attention. More recently, in 2019, reports indicate that child soldiers in Yemen have been chewing khat in order to remain alert on the battlefield.

(also known as ''cat''), a Schedule I substance that possesses a similar chemical structure to the khat plant's cathinone active component. However, both the side effects and the addictive properties of methcathinone are much stronger than those associated with khat use. When khat leaves dry, the more potent chemical, cathinone, decomposes within 48 hours, leaving behind the milder chemical, cathine. Thus, harvesters transport khat by packaging the fresh leaves and stems in plastic bags or wrapping them in banana leaves to preserve their moisture and keep the cathinone potent. It is also common for them to sprinkle the plant with water frequently or use refrigeration during transportation. When the khat leaves are chewed, cathine and cathinone are released and absorbed through the mucous membranes of the mouth as well as the lining of the stomach. The action of cathine and cathinone on the

Demographics

An estimated 5 to 10 million people globally use khat on a daily basis. It is grown principally by communities in the Horn of Africa and the Arabian peninsula, where khat-chewing has a long history as a social custom dating back thousands of years. The traditional form of khat chewing in Yemen involves only male users; khat chewing by females is less formal and less frequent. Researchers estimate about 70–80% of Yemenis between 16 and 50 years old chew khat, at least on occasion. Approximately 60–90% of male and 35% of female Yemenis chew khat daily. Before

. Some Somali community organisations also campaigned for khat to be banned. As a result of these concerns, the Home Office commissioned successive research studies to look into the matter, and in 2005, presented the question of khat's legal status before the Advisory Council on the Misuse of Drugs. The study concluded that most of the participants who were using khat were using it moderately in terms of both the quantity used and the frequency and duration of chewing sessions, and that khat use was typically a social activity. Only a small minority of the study participants' khat use was judged to be excessive. After a careful review of the evidence, the Advisory Council on the Misuse of Drugs recommended in January 2006 that the status of khat as a legal substance should remain for the time being. In 2008,

The committee had shortly before also completed an inquiry and a report recommending that the British authorities refrain from banning the plant. On 12 May 2014, the House of Lords passed a Motion to Approve the Misuse of Drugs Act 1971 (Designation)(Amendment) (No. 2)(England, Wales and Scotland) Order 2014, in order to control ''Catha edulis'' as a Class C drug. An amendment was proposed stating that, "this House regrets that Her Majesty’s Government’s plans for the introduction of the Order do not include provisions for a 12-month review of the impact of the reclassification of khat in view of the highly unusual community focus of its use, for putting a detailed policing strategy in place before a ban takes effect, or for a health strategy to prevent a transfer of addiction to other substances; and do not commit the Department for International Development to do more work with the government of Kenya to alleviate the effect of the reclassification on the Kenyan economy." However, the amendment was defeated by vote. The prohibition came into effect on 24 June 2014. In January 2015, the ''
