Can you die from cocaine overdose?

Yes. Cocaine overdose can be fatal, and unlike opioid overdose, there is no reversal agent. Cocaine kills through cardiovascular emergencies, not respiratory depression.

How cocaine kills

Heart attack (cocaine causes coronary artery spasm and clot formation, even in young people with no prior heart disease). Stroke (severe vasoconstriction and hypertension rupture blood vessels). Hyperthermia (body temperature exceeds 104°F, causing organ failure). Seizures (can be fatal if prolonged). Aortic dissection (the aorta tears under extreme blood pressure). These can occur with any use, including first-time use.

There is no naloxone for cocaine

Naloxone reverses opioid overdose. There is no equivalent for stimulant overdose. Treatment is entirely supportive: manage symptoms, cool the body, treat seizures, and provide cardiac care. This is why cocaine overdose requires emergency medical care, not a reversal drug.

Added danger: Fentanyl contamination

Cocaine supplies are increasingly contaminated with fentanyl. A cocaine user with no opioid tolerance can die from even trace fentanyl contamination. Carry naloxone even if you only use cocaine. Test with fentanyl strips.

Response

Call 911 immediately for: chest pain, seizure, unresponsiveness, extreme agitation, or body temperature above 104°F. Keep the person as calm as possible. Cool them if overheating. Good Samaritan laws protect you from drug charges when calling 911 for an overdose in most states.
