Toxicology – Synthetic Cathinones (“Bath Salts”)
Source
“Bath salts” refer to synthetic stimulant drugs derived from cathinones, compounds related to substances found in the khat plant (Catha edulis), native to East Africa and the Middle East. These products are often sold in retail settings under misleading names and packaging.
Typical Presentation
Use typically occurs in social or party settings, where individuals may repeatedly take the substance. This can lead to escalating toxicity, including severe agitation and psychotic behavior, sometimes resulting in harm to self or others.
Clinical Features
These agents produce a sympathomimetic toxidrome characterized by agitation, hallucinations, paranoia, tremors, hyperreflexia, nausea, vomiting, tachycardia, hypertension, dilated pupils, and sweating. Severe complications may include violent behavior, rhabdomyolysis, acute kidney injury, myocardial infarction, and self-harm.
Mechanism of Action
Synthetic cathinones act similarly to amphetamines by increasing levels of serotonin, dopamine, and norepinephrine in the brain, leading to marked central nervous system stimulation.
Management
Treatment is supportive. Benzodiazepines are first-line therapy for agitation, anxiety, and tachycardia. In severe cases, physical or chemical restraints may be required to ensure safety.

Key Points
- These substances are often not detected on standard drug screening tests.
- Common compounds include MDPV, methylone, and mephedrone.
