The Short Answer
Khat (Catha edulis) contains cathinone, a natural stimulant that enhances alertness and energy by increasing norepinephrine and dopamine levels in the brain. This East African plant acts as both a cognitive enhancer and appetite suppressant through its amphetamine-like alkaloids.

Origin & History
Natural habitat
Catha edulis, commonly known as Khat or Miraa, is a flowering plant native to East Africa. The leaves are traditionally chewed for their stimulant effects, often harvested fresh for immediate use.
“Khat has a long history of use in East African and Arabian cultures, often consumed in social settings for its stimulating effects and cultural significance.”Traditional Medicine
Scientific Research
Research on Khat focuses on its psychoactive properties, with some studies highlighting potential health risks associated with prolonged use. RCTs and meta-analyses are limited in scope.
Preparation & Dosage
Fresh leaves are typically chewed in small quantities, with effects felt after chewing 100-200 grams. Consult a healthcare provider before use.
Nutritional Profile
Catha edulis leaves contain cathinone (primary psychoactive alkaloid, ~0.1–0.9% fresh weight, degrades rapidly post-harvest), cathine (norpseudoephedrine, ~0.1–0.5% dry weight), and norephedrine. Macronutrients are modest: crude protein ~15–20% dry weight (including alkaloid-bound nitrogen), dietary fiber ~20–25% dry weight (cellulose, hemicellulose), and minimal fats (~2–4%). Micronutrients include ascorbic acid (Vitamin C, ~150–500mg/100g fresh leaves), beta-carotene (~3–8mg/100g), riboflavin (Vitamin B2, ~0.3mg/100g), and calcium (~300–400mg/100g dry weight). Tannins are abundant (~7–15% dry weight), contributing astringency and antiplaque activity via precipitation of salivary proteins. Flavonoids including rutin and quercetin glycosides are present (~1–3% dry weight) with antioxidant capacity. Bioavailability of cathinone is highest within 24–48 hours of harvest (fresh chewing); tannins reduce iron and zinc absorption when co-consumed with meals. Chlorogenic acids (~0.5–2% dry weight) contribute to metabolic stimulation.
How It Works
Mechanism of Action
Cathinone, the primary active compound in khat, blocks dopamine and norepinephrine reuptake transporters while promoting their release from nerve terminals. This dual action increases synaptic concentrations of these neurotransmitters in brain regions associated with alertness, mood, and appetite regulation. The compound also stimulates the sympathetic nervous system, leading to increased metabolic rate and cardiovascular activity.
Clinical Evidence
Human studies on khat primarily focus on epidemiological research rather than controlled trials. Observational studies of 200-500 regular users in Yemen and Ethiopia show increased alertness lasting 2-4 hours after chewing 100-200g of fresh leaves. Cross-sectional studies indicate appetite suppression effects with average weight reduction of 3-5kg among chronic users compared to non-users. However, controlled clinical trials examining therapeutic benefits are extremely limited due to legal restrictions in most countries.
Safety & Interactions
Khat can cause insomnia, anxiety, increased heart rate, and hypertension, particularly with doses exceeding 200g of fresh leaves. It may interact dangerously with MAO inhibitors, stimulant medications, and blood pressure drugs by amplifying their effects. Chronic use is associated with dental problems, gastric issues, and potential psychological dependence. Pregnant women should avoid khat as cathinone crosses the placental barrier and may affect fetal development.

Frequently Asked Questions
How much cathinone is in khat leaves?
Fresh khat leaves contain 0.1-2.0% cathinone by weight, with young shoots having the highest concentrations. The cathinone content rapidly degrades within 48 hours after harvesting, which is why fresh consumption is preferred.
How long do khat effects last?
Khat's stimulant effects typically peak within 1-2 hours of chewing and last 3-4 hours total. The appetite suppression effects may persist for 6-8 hours after consumption.
Is khat legal in the United States?
Khat is classified as a Schedule I controlled substance in the United States since 1993. Possession, cultivation, and distribution are illegal with potential criminal penalties.
What's the difference between khat and synthetic cathinone?
Natural khat contains cathinone plus over 40 other alkaloids that modulate its effects, while synthetic cathinones (bath salts) are isolated compounds that are more potent and dangerous. Synthetic versions can be 10-50 times stronger than natural cathinone.
Can khat cause addiction?
Khat can cause psychological dependence with regular use, though physical withdrawal symptoms are typically mild. Studies show 10-15% of regular users develop problematic use patterns with difficulty stopping despite negative consequences.
Is khat safe to use during pregnancy or while breastfeeding?
Khat is not recommended during pregnancy, as cathinone and cathine can cross the placental barrier and may affect fetal development; animal studies suggest potential teratogenic effects. Limited safety data exists for breastfeeding mothers, and stimulant alkaloids may pass into breast milk, potentially affecting infant development and sleep patterns. Pregnant and nursing women should avoid khat consumption and consult healthcare providers before use.
Does khat interact with common medications like stimulants or antidepressants?
Khat may interact with sympathomimetic medications (decongestants, ADHD drugs) and monoamine oxidase inhibitors (MAOIs) due to its norepinephrine-releasing effects, potentially causing dangerous blood pressure spikes or serotonin syndrome. Concurrent use with SSRIs, tricyclic antidepressants, or other serotonergic agents may increase the risk of overstimulation and adverse effects. Individuals taking prescription medications should consult a healthcare provider before khat use.
What is the difference between chewing fresh khat leaves versus dried or powdered forms in terms of effects?
Fresh khat leaves contain the highest concentration of cathinone (the primary active alkaloid), which begins to degrade within 24–48 hours of harvesting, making fresh leaves significantly more potent than dried forms. Dried and powdered khat contain lower active alkaloid levels and longer action times due to slower absorption and release of the remaining cathinone and cathine. Fresh khat typically produces more immediate and intense effects (within 15–30 minutes), while processed forms take longer to take effect and deliver milder, more sustained stimulation.
