Khat (Catha edulis), also known as qat, cat, or miraa, is a flowering evergreen shrub that has played a significant role in East African and Arabian cultures for centuries. This psychoactive plant continues to be widely consumed today, particularly in Somalia, Yemen, Ethiopia, and Kenya, where it serves both recreational and cultural purposes.
What is Khat?
Khat is a slow-growing evergreen plant native to the Horn of Africa and the Arabian Peninsula. The world’s largest consumers are Eastern Africans, particularly Somalis, and nearby Yemen, with the largest producers/exporters being Ethiopia and Kenya. The plant can grow into a small tree, reaching heights of up to 25 feet, though it’s typically harvested as a shrub.
The active consumption method involves chewing the fresh leaves and young shoots of the plant. Users typically hold the plant material in their cheek, similar to chewing tobacco, allowing the active compounds to be absorbed through the oral mucosa. The potency of khat is highest when consumed fresh, as the psychoactive compounds degrade rapidly after harvesting.
Active Compounds and Effects
Khat contains the alkaloid cathinone, a stimulant which causes greater sociability, excitement, mild loss of appetite and mild euphoria. The primary psychoactive compound, cathinone, is chemically similar to amphetamine and produces comparable stimulant effects.
When consumed, khat typically produces the following effects:
Immediate Effects (1-3 hours):
- Increased alertness and energy
- Enhanced sociability and talkativeness
- Mild euphoria
- Reduced appetite
- Increased heart rate and blood pressure
Extended Use Effects:
- Prolonged wakefulness
- Increased libido
- Heightened confidence
- Enhanced concentration (initially)
The effects of khat consumption can last several hours, with the comedown effects of khat can last around 24 hours and may include fatigue, depression, and irritability.
Cultural and Traditional Significance
Khat holds deep cultural significance across East Africa and the Arabian Peninsula. The leaves and stem have been traditionally chewed by people in East African countries as a recreational drug to elevate mood (as a euphoriant). In many communities, khat consumption is integrated into social gatherings, religious ceremonies, and daily routines.
In Somali culture, khat sessions often serve as important social events where community members gather to discuss current events, conduct business, and maintain social bonds. Similarly, in Yemen, khat chewing is traditionally associated with afternoon social gatherings called “maqyal.”
The plant also holds economic importance for millions of people in producing countries, providing livelihoods for farmers, traders, and transporters involved in the khat supply chain.
Health Effects and Risks
While khat has been used traditionally for centuries, modern research has identified several health concerns associated with its consumption.
Short-term Health Effects:
- Increased blood pressure and heart rate
- Insomnia and sleep disturbances
- Dehydration
- Constipation
- Loss of appetite
Long-term Health Risks: Additionally, there are reports of liver damage (chemical hepatitis) and of cardiac complications, specifically myocardial infarctions. This mostly occurs among long-term chewers of khat or those who have chewed too large a dose.
Other serious long-term health concerns include:
- Using khat is associated with mental health conditions such as psychosis which is similar to amphetamine psychosis. It has also been associated with depression, mood swings and violent behaviour.
- Dental problems, including tooth loss and gum disease
- Gastrointestinal issues
- Cardiovascular complications
Recent research has also highlighted concerns about dependency potential, with some users developing tolerance and experiencing withdrawal symptoms when discontinuing use.

Legal Status Worldwide
The legal status of khat varies significantly across different countries and jurisdictions. According to applicable tax laws or secondary sources, khat appears to be legal in Djibouti, Ethiopia, Kenya, Somalia, and Yemen, but is banned in Jordan.
Countries where khat is legal or tolerated:
- Ethiopia (legal production and consumption)
- Kenya (legal, major exporter)
- Somalia (legal and culturally accepted)
- Yemen (legal, deeply integrated into culture)
- Djibouti (legal)
Countries where khat is banned or controlled:
- United States (classified as a Schedule I controlled substance)
- United Kingdom (Class C drug since 2014)
- Canada (controlled substance)
- Most European Union countries
- Australia (illegal)
In the United States, the person who possessed the khat would likely be charged with only a misdemeanor possession of the Schedule IV substance in some cases, though federal classification varies.
Contemporary Issues and Considerations
The use of khat continues to present various challenges in modern society. Using khat can lead to a spectrum of health impacts, from mild issues like mood swings and insomnia to severe risks, including heart attacks and psychological disorders. Awareness of these risks is crucial for anyone considering khat.
Social and Economic Impacts:
- Significant household expenditure in consuming communities
- Time lost from productive activities
- Potential family and relationship conflicts
- Economic burden on healthcare systems
Public Health Concerns:
- Need for culturally sensitive healthcare approaches
- Integration of traditional practices with modern medical understanding
- Education about potential risks while respecting cultural traditions
Medical Applications and Research
While primarily known for recreational use, as a medicine, khat leaf is used for diabetes, muscle strength, to lower the need for food and sleep, and to increase aggression, but there is no conclusive scientific evidence supporting these traditional medicinal claims.
Current research focuses on:
- Understanding the pharmacology of cathinone and related compounds
- Investigating potential therapeutic applications
- Developing treatment approaches for problematic use
- Studying cultural and social factors affecting consumption patterns
Harm Reduction and Safe Use Considerations
For individuals who choose to use khat in legal jurisdictions, several harm reduction strategies can minimize risks:
General Safety Guidelines:
- Consume only fresh, quality khat from reliable sources
- Maintain proper hydration
- Avoid mixing with other stimulants or substances
- Monitor for adverse reactions
- Seek medical attention if experiencing chest pain, severe anxiety, or other concerning symptoms
Long-term Considerations:
- Regular health check-ups, particularly cardiovascular screening
- Dental hygiene maintenance
- Mental health monitoring
- Balanced nutrition despite appetite suppression
Conclusion
Khat remains a complex subject that intersects traditional culture, public health, and international drug policy. While deeply rooted in East African and Arabian cultures, the plant’s psychoactive properties present both benefits and risks that continue to be studied and debated.
Understanding khat requires balancing respect for cultural traditions with awareness of potential health risks. As research continues to evolve, it’s essential to approach this topic with cultural sensitivity while promoting informed decision-making about its use.
For individuals in communities where khat is culturally significant, accessing culturally competent healthcare and education resources is crucial. Meanwhile, policymakers must continue to grapple with the complex task of regulating a substance that holds deep cultural meaning for millions of people worldwide.
Whether viewed through the lens of traditional medicine, cultural practice, or public health concern, khat represents a unique challenge that requires nuanced, informed approaches that respect both cultural heritage and individual well-being.
