Stimulant Toxicity - Key Points

Central & Peripheral catecholamine surge
– Characteristic clinical toxicological syndrome

Specific agents
– Cocaine, amphetamines, decongestants,
cannabinoids, Mephedrone, MDPV, phenethylamines
– Often unavailable for decontamination & detection
– Treat the patient, not the agent

Importance - reduce severity of poisoning
(avoid complications)
– Benzodiazepines & Hyperthermia prevention
