A cocaine overdose can rapidly become a life-threatening emergency. Knowing how to identify the early signs can significantly improve the chances of survival and recovery.
Approximately 700 individuals die daily from drug related complications and overdoses in Pakistan, totaling around 250,000 deaths annually.
Here are the top seven symptoms of cocaine overdose, detailed for better understanding and quick recognition
7 Cocaine Overdose Symptoms

1. Extreme Agitation and Anxiety
During a cocaine overdose, individuals frequently exhibit extreme agitation, restlessness, and panic. They may struggle to communicate clearly, showing intense emotional distress. This heightened anxiety can escalate quickly, potentially leading to dangerous behaviors or accidents.
The agitation associated with overdose can also lead to paranoia or hallucinations, further complicating the situation. Calming the individual and seeking immediate professional help is crucial.
2. Rapid or Irregular Heartbeat
Cocaine overdose profoundly affects cardiovascular health, causing rapid or irregular heartbeats known as arrhythmias. These abnormal rhythms strain the heart, greatly increasing the risk of a heart attack or cardiac arrest.
Persistent rapid heartbeat during an overdose is an urgent sign requiring immediate medical intervention. Cocaine users should understand these risks, detailed in our previous blog on cocaine addiction treatment.
3. High Blood Pressure and Chest Pain
One of the most severe symptoms of cocaine overdose is dangerously high blood pressure, which can trigger intense chest pain. This situation may rapidly escalate into life-threatening cardiovascular events, such as heart attacks.
Chest pain during a cocaine overdose demands immediate medical attention, as it indicates severe cardiac stress that could quickly become fatal.
4. Difficulty Breathing
Respiratory distress is a critical indicator of cocaine overdose. Individuals may experience shortness of breath, rapid breathing, or difficulty maintaining adequate oxygen levels, often leading to panic.
This symptom is especially dangerous because it can swiftly progress to respiratory failure, emphasizing the urgency of immediate medical intervention.
5. Severe Nausea and Vomiting
Cocaine overdose commonly leads to severe gastrointestinal disturbances, including persistent nausea and vomiting. These symptoms not only cause dehydration but may also hinder breathing, increasing the risk of aspiration.
Continuous vomiting during an overdose is a serious health concern that requires professional medical care to manage effectively.
6. Elevated Body Temperature (Hyperthermia)
Hyperthermia is another critical symptom of cocaine overdose, characterized by excessively high body temperature. This condition can cause severe dehydration, organ failure, seizures, and even death if not promptly treated.
Immediate cooling strategies and emergency medical assistance are vital for managing hyperthermia effectively.
7. Loss of Consciousness and Seizures
One of the most severe outcomes of cocaine overdose is loss of consciousness, often accompanied by seizures. These neurological symptoms signify critical brain distress and are extremely dangerous.
Immediate medical attention is essential to prevent lasting neurological damage or death from prolonged seizures or unconsciousness.
How much cocaine is considered as overdose?
The amount of cocaine that leads to an overdose varies based on individual factors such as tolerance, body weight, metabolism, and method of use (snorting, smoking, injecting, or swallowing). However, consuming over 1.2 grams in a single dose is considered highly dangerous and can be fatal.
For some individuals, especially those with low tolerance, an overdose can occur at much lower doses, sometimes as little as 30-60 mg.
The risk increases significantly when cocaine is mixed with alcohol, opioids (such as fentanyl), or other stimulants, as these combinations can intensify its toxic effects, leading to heart attacks, strokes, or respiratory failure. Since cocaine purity levels vary, even experienced users can accidentally consume a lethal dose.
