Cocaine overdose | signs and emergency care

Cocaine overdose can cause seizures, stroke or cardiac arrest. It can begin within minutes, and an amount that caused no problem before can still cause it.

Cocaine overdose happens when cocaine overwhelms the brain, heart or other organs. It can develop suddenly, even after earlier use passed without an obvious emergency. Chest pain, extreme agitation, overheating or seizures can signal immediate danger. If you think a friend or partner has taken too much cocaine, contact an ambulance instead of waiting to see whether the signs of cocaine overdose settle.

How cocaine overwhelms the body

Cocaine increases nervous-system activity and places intense pressure on the cardiovascular system. TThe National Institute on Drug Abuse lists seizures and cardiovascular emergencies among cocaine’s serious effects. The signs of cocaine overdose vary because strength, contaminants, route of use and individual health all influence the reaction.

Cocaine use can carry serious and potentially life-threatening risks, including overdose.

Cocaine overdose symptoms

Cocaine overdose symptoms can involve several rapidly changing problems. Serious cocaine overdose signs include: 

  • severe chest pain or an irregular heartbeat 
  • extreme panic, paranoia or hallucinations 
  • very high body temperature and heavy sweating 
  • shaking, rigid muscles or repeated seizures 
  • breathing difficulty, collapse or unresponsiveness

When the signs become urgent

You do not need to see every symptom before calling an ambulance. A stroke may cause facial weakness, difficulty speaking or sudden loss of movement. Treat any severe or rapidly worsening reaction after cocaine use as an emergency.

What a cocaine overdose can feel like

If you use cocaine yourself, an overdose can begin with crushing chest pressure, a racing heart or the sense that you cannot breathe. You may feel intensely frightened, watched or convinced that something terrible is happening. Headache, nausea, dizziness and painful muscle tension can appear as your body overheats. What a cocaine overdose feels like differs between people, and the confusion can make it impossible to say what is wrong. For anyone standing nearby, that is the moment to stop asking and call for help.

Call us

You can overdose on powdered cocaine, freebase cocaine or crack cocaine. Smoking crack delivers cocaine to the brain very quickly, which can produce an intense effect and rapid repeat use. Mixing cocaine with alcohol, opioids or other stimulants adds further unpredictability. Repeated use can also contribute to cocaine addiction, even when use is not daily. 

How much cocaine causes an overdose?

There is no dependable answer to how much cocaine causes an overdose. A bigger dose raises the risk, but there is no amount that counts as safe. Purity varies, cocaine may contain unknown substances, and tolerance can change after a break. Heart conditions, medication, sleep loss and repeated doses also alter the risk. An amount that was tolerated previously can therefore cause a medical crisis on another occasion. 

A cocaine overdose is a serious sign that cocaine use is no longer under control. Even so, a frightening experience is not always enough to make stopping possible, because an addiction can be so strong that the urge to use returns anyway. If your loved one keeps struggling with quitting cocaine, despite the risks, call us on +27 21 541 0643. Share your worries and we can give you personal advice.

Call an ambulance immediately if you suspect an overdose. Tell the operator what was taken, when it was used and whether other substances may be involved. Stay nearby without restraining the person, and move hard or dangerous objects away when possible. Do not give food, drink or another drug, and do not try to make the person vomit.

While medical help is coming

If the person is unresponsive but breathing, place them on their side and keep their airway clear. If breathing stops, begin CPR if you know how and follow the emergency operator’s instructions. someone to hospital yourself if they are severely agitated, having a seizure or unconscious.

Cocaine overdose treatment

Treatment for cocaine overdose begins with stabilising breathing, circulation, and temperature, and bringing seizures under control. Medication can reduce severe agitation, blood pressure or seizure activity, while cooling measures treat dangerous overheating. There is no single antidote that reverses the effects of cocaine, so treatment responds to the problems affecting that person.

When opioids may be involved

Cocaine can contain fentanyl or another opioid without anyone knowing. Very slow breathing, blue or grey lips, pinpoint pupils and unresponsiveness suggest an opioid effect rather than stimulant toxicity alone. Naloxone, the medicine used to reverse an opioid overdose, does nothing for cocaine. When an opioid may be involved, the ambulance operator can say whether to use it. Emergency medical care remains essential afterwards.

An addiction assessment can look at the overdose alongside physical health, emotional wellbeing and the pattern of use behind it. Leaving hospital without a continuing treatment plan can allow the same pattern to resume quickly.

FAQ

Frequently asked questions about cocaine overdose

Can you overdose on cocaine?

You can overdose on cocaine in any of its forms, and the hard part is telling an overdose apart from an intense high. Both bring a racing heart, sweating and agitation. What sets an overdose apart is that the reaction keeps escalating instead of easing, and that chest pain, confusion or loss of consciousness appear. If it keeps getting worse, call for help.

How much cocaine does it take to overdose?

A first line of cocaine can be fatal, while years of daily use can pass without one. What it was cut with, how fast it reached the brain and the state of the person’s heart all shift the outcome. A bigger dose pushes the risk up, but it never makes the reaction predictable.

Can you overdose on crack cocaine?

Crack cocaine can cause an overdose, and the timing is what makes it dangerous. Smoking crack brings the effect on within seconds and takes it away almost as quickly, so another dose often follows before the first one has cleared. Several doses can follow within half an hour. The dose that causes the emergency is often not the largest one.

What happens if you overdose on cocaine?

A cocaine overdose usually develops in stages. Blood pressure, heart rate and body temperature climb first, which is when agitation, sweating and chest pain appear. If the strain continues, the heart rhythm can fail or a vessel in the brain can rupture, and seizures can follow. Cardiac arrest or a stroke can kill within minutes.

How can a cocaine overdose become fatal?

A cocaine overdose can kill in two ways, and both can happen within minutes. Cocaine can cause an irregular heart rhythm or a full cardiac arrest, and it can raise blood pressure enough to rupture a vessel in the brain. A body temperature above 40°C can damage the organs as well. An opioid in the powder can stop someone breathing altogether.
