Cathinone

Cathinone is a naturally occurring stimulant found in the leaves of the khat plant (Catha edulis), and it is the structural template for a large family of synthetic derivatives known as substituted or synthetic cathinones — the drugs widely sold as 'bath salts'. The natural compound produces a mild, khat-chewing stimulation; the synthetic derivatives, engineered to mimic and often exceed cocaine, methamphetamine, and MDMA, are far more potent and dangerous. This page covers the cathinone class as a whole; for the natural plant see the khat page, and for specific synthetic members see the mephedrone, MDPV, methylone, and 3-MMC pages.

Cathinones are structurally related to amphetamine and act as central nervous system stimulants: they increase the activity of dopamine, norepinephrine, and serotonin by promoting their release and blocking their reuptake, raising levels of these neurotransmitters in the brain. This produces stimulation, euphoria, and alertness. Synthetic cathinones vary widely in potency and which transporters they target — some (like MDPV) are extremely potent dopamine-norepinephrine reuptake inhibitors, which contributes to their intense, compulsive, and dangerous effects compared with the mild natural compound.

Effects are stimulant-like: euphoria, increased energy, alertness, sociability, and raised heart rate and blood pressure. The natural cathinone in khat is comparatively mild; synthetic cathinones can produce powerful stimulation resembling cocaine, methamphetamine, or MDMA, often with a strong compulsion to redose. Higher doses and more potent synthetics bring agitation, paranoia, hallucinations, and — notably — a documented pattern of severe, sometimes violent, psychotic episodes ('excited delirium'). A comedown with fatigue, low mood, and craving is common.

The natural cathinone in khat is a relatively mild stimulant, but synthetic cathinones ('bath salts') are among the more dangerous stimulants in circulation. They strain the cardiovascular system — dangerously high heart rate, blood pressure, chest pain, and risk of heart attack and stroke — and can cause severe hyperthermia (overheating), seizures, kidney failure, and rhabdomyolysis (muscle breakdown). Psychiatrically they are notorious for agitation, paranoia, hallucinations, and violent, self-endangering 'excited delirium', which has been linked to deaths. Because formulas change constantly to evade the law, potency and identity are wildly unpredictable, dosing is guesswork, and products sold as one cathinone are frequently another or a mixture; contamination, including with fentanyl in the broader illicit supply, is a risk. Dependence and compulsive redosing develop readily. Injecting or sharing equipment adds infection risk. Anyone showing dangerously high temperature, chest pain, seizures, extreme agitation or psychosis, or collapse needs emergency care — call 911, and Poison Control at 1-800-222-1222 can advise.
