Khat (Miraa)

Khat is a plant (Catha edulis) whose fresh leaves and stems are chewed for their stimulant effect. The active compounds, cathinone and cathine, produce effects similar to amphetamine. It is primarily grown in the Meru region of Kenya, which is the world's largest khat-producing area.

Miraa is the name used in Kenya; muguka is a more potent variety from younger shoots. In the Horn of Africa it is known as qat or jaad. It is central to social life in Eastern Kenya, Somalia, Ethiopia, and Yemen.

Khat is legal in Kenya and its production is a major economic activity in Meru and Nyambene. It is also exported internationally, though it is banned in many destination countries including Uganda, Tanzania, and the UK.

Khat is deeply embedded in the culture of Eastern Kenya and Somalia. It is used at social gatherings, weddings, religious observances, and business meetings. In many communities, refusing khat is considered impolite.

Truck drivers, night watchmen, and others who need to stay awake for extended periods use khat for its stimulant effect. This occupational use is common and accepted in many contexts.

Many users report that khat improves concentration and productivity, particularly for studying. However, the crash that follows heavy use significantly impairs function the next day.

Physical dependence on khat is less pronounced than with alcohol or heroin. However, psychological dependence is common, particularly in communities where daily use is the social norm.

Muguka (the more potent young shoot variety) carries a higher dependence risk than miraa (mature leaf). Withdrawal from heavy use causes low mood, fatigue, and irritability that can be quite distressing.

Eastern Kenya has the highest khat use nationally at 9.6% (NACADA 2022). Men are approximately eight times more likely to use khat than women. Northern Eastern and Nairobi regions also have significant prevalence.

Somali-Kenyan communities have culturally embedded khat use that extends across all age groups and includes women, though female use is less public.

The transport sector (truck drivers, matatu workers) has disproportionately high khat use linked to the need to stay awake on long journeys.

Kenya is the world's largest producer of khat, with production centred in Meru county. The crop generates billions of shillings annually and employs hundreds of thousands of people in production, trading, and transport.

The legal status of khat in Kenya creates a complex public health situation: a crop with major economic value and deep cultural significance also drives measurable harm including cardiovascular disease, mental health problems, and family financial strain.

Muguka, the more potent young-shoot variety, is the subject of growing concern from public health authorities because of its higher cathinone content and the speed at which heavy dependence can develop.
