Cocaine Overdose Signs, Symptoms & Treatment

Cocaine overdose: get help immediately

Call 911 for suspected overdose if someone has chest pain, a seizure, severe overheating, trouble breathing, collapses, or cannot be woken. Tell responders what may have been taken. If opioid exposure is possible, give naloxone if available and follow the dispatcher’s instructions.

• Stay with the person and move sharp objects or other hazards away if safe.
• Keep the surroundings calm and avoid crowding or arguing with someone who is agitated.
• If a seizure occurs, protect the head, clear the area, and turn the person onto their side when possible. Do not restrain them or put anything in their mouth.
• If the person is not breathing normally, follow the 911 dispatcher’s instructions for CPR and rescue breathing.
• Tell responders about cocaine, alcohol, medication, or other drugs that may have been taken, along with known medical conditions.

The CDC’s stimulant guide explains why serious stimulant toxicity requires medical care. Naloxone can reverse an opioid component when fentanyl or another opioid is also involved; it does not reverse cocaine toxicity.

Symptoms and signs of cocaine use

Family or friends may notice changes in behavior, sleep, mood, or physical health. Objects such as rolled bills, cut straws, small pipes, vials, envelopes, needles, or tourniquets can raise questions about drug use. Look at the overall pattern and changes from the person’s usual behavior.

Physical signs

Dilated pupils, sweating, tremor, a rapid heartbeat, or injection marks.

Behavior and mood

Unusual excitement, secrecy, defensiveness, withdrawal from others, mood swings, or difficulty concentrating.

More concerning changes

Confusion, paranoia, hallucinations, or delusional beliefs, especially with marked agitation.

These signs can have other causes. A calm conversation and a professional assessment can help determine what is happening and what support is needed.

Immediate effects of cocaine use

Cocaine stimulates the central nervous system. It can produce increased energy and alertness, restlessness, a reduced appetite, and difficulty sleeping. Heart rate and blood pressure can rise, while blood vessels narrow. Severe effects can occur even during a first episode of use.

How quickly effects begin and how long they last depend on the route, amount, and other substances involved. A short-lived high may encourage repeat dosing while the body is still under strain. The fading of the pleasurable effect does not mean the cardiovascular risk has passed.

Long-term effects

Repeated use can damage the cardiovascular system and affect mood, sleep, memory, and relationships. Snorting can injure the nasal tissues, including the septum; smoking can damage the lungs. Paranoia, hallucinations, irritability, and episodes of aggression may become more prominent for some people.

These changes can continue outside the immediate period of intoxication. Medical care should address symptoms such as chest pain, persistent breathing problems, nasal injury, or major changes in behavior alongside treatment for cocaine use.

Street names and availability

Names include coke, blow, snow, crack, rock, base, toot, flake, cola, lady, pasta, hubba, and pestillos. Some refer to a particular form or vary by region. The name a substance is sold under does not establish its contents.

Illicit cocaine is sold as powder or forms intended for smoking. Cocaine also has limited regulated medical uses as a topical anesthetic; those uses differ from the unregulated drug supply. Fentanyl or other substances may be present in an illicit product without the buyer knowing.

Can you overdose on cocaine?

Yes. Cocaine can cause a heart attack, dangerous rhythm disturbance, seizure, stroke, overheating, or breathing problems. Combining it with heroin, fentanyl, alcohol, or other substances can increase or change the risk. Injecting or smoking delivers the drug rapidly, but overdose can occur with any route.

The amount, purity, co-exposures, tolerance, and the person’s cardiovascular health all matter. A previous experience without an emergency does not establish that a later episode will be safe.

How much cocaine does it take to overdose?

There is no reliable amount a person can use to identify a personal “safe threshold.” Serious toxicity has occurred after small amounts, while an illicit product’s actual contents and concentration may be unknown. Repeated dosing can also increase the amount in the body before the full harm becomes apparent.

For an emergency, act on symptoms rather than trying to calculate a dose. Chest pain, collapse, seizures, severe overheating, or abnormal breathing require immediate help.

Cocaine overdose symptoms

Heart and breathing

Chest pain, a very fast or irregular heartbeat, difficulty breathing, or collapse.

Temperature and movement

Severe overheating, heavy sweating, shaking, or seizures.

Thinking and behavior

Extreme agitation, panic, confusion, paranoia, hallucinations, or delirium.

Other physical signs

Nausea, vomiting, severe headache, weakness, or loss of consciousness.

A person can have dangerous stimulant toxicity while awake and agitated. Slow or stopped breathing may indicate an opioid co-exposure or a severe medical emergency. Call 911 and describe what you observe.

How cocaine toxicity affects the body

Cocaine changes neurotransmitter signaling and narrows blood vessels. The heart may be working harder while its blood supply is reduced; the brain and other organs can also be affected. Toxicity can progress from marked stimulation and agitation to seizures, cardiovascular collapse, or loss of consciousness.

Cocaine toxicity is sometimes described in three stages—early stimulation, escalating stimulation, and a later depressed or collapsed state. These are a way to describe possible progression, not a sequence to wait through. Someone can deteriorate quickly and needs help at the first serious warning signs.

Cocaine overdose statistics: the latest final figures

CDC’s final 2024 mortality figures show 21,945 cocaine-involved overdose deaths, compared with 29,449 in 2023. The age-adjusted rate fell from 8.6 to 6.3 deaths per 100,000 people. A death involving multiple drugs can appear in more than one drug category.

For use rather than deaths, SAMHSA’s 2024 survey estimates that approximately 4.3 million people aged 12 or older used cocaine in the past year. These measures answer different questions: survey use, emergency treatment, and fatal overdose are not interchangeable.

The original guide’s emergency-department figure of approximately 482,000 visits in 2008 belongs to historical surveillance. For overdose prevention, combine these national figures with current local alerts about the drug supply.

Cocaine overdose treatment

Emergency clinicians assess breathing, circulation, temperature, heart rhythm, and neurological symptoms. Treatment may include oxygen or breathing support, medication to control agitation or seizures, cooling, and management of a heart attack, stroke, or other complication.

There is no take-home antidote that reverses cocaine itself. The priority is rapid recognition and professional treatment. Share what you know about timing, route, other substances, regular medication, and medical conditions; this can help guide care.

Withdrawal symptoms

When cocaine use stops after repeated use, a crash may involve exhaustion, low mood, anxiety, changes in sleep, vivid dreams, increased appetite, and strong cravings. Symptoms and recovery time vary, and mood or craving difficulties can continue after the initial crash.

Withdrawal is distinct from the acute toxicity that caused an overdose. Severe depression, suicidal thoughts, psychosis, or inability to care for oneself call for urgent assessment. Follow-up care can support safety and reduce the chance of returning to use.

Cocaine dependence and addiction

Cocaine can strongly reinforce repeated use. A cocaine use disorder involves a pattern of impaired control, continued use despite harm, or other symptoms that disrupt life. An overdose can occur without a pre-existing addiction, and an overdose event alone does not establish the diagnosis.

Genetics, environment, stress, and repeated exposure all contribute to vulnerability. The 2008 CAMK4 research cited in the original discussion investigated biological mechanisms and associations with cocaine dependence. It is research into susceptibility, rather than a routine genetic screening test that predicts an individual’s outcome.

Daily rhythms and sleep also interact with drug use and recovery. A treatment assessment should examine the person’s actual experience, including sleep, mental health, family history, and social circumstances.

Addiction treatment after an overdose

An overdose is an opportunity to connect someone with an assessment and continuing support. Depending on medical, psychiatric, and practical needs, care may be outpatient, intensive outpatient, or residential. A plan should address other substance use and any co-occurring mental-health conditions.

Peer groups and twelve-step programs can provide community and encouragement. Individual, group, and family therapy can help with triggers, relationships, and recovery skills. Ask how the program handles a return to use and how it supports the transition back into everyday life.

Therapy and complementary approaches

The ASAM/AAAP stimulant-use guideline identifies contingency management as a central treatment approach. It uses tangible rewards to support agreed goals. Cognitive behavioral therapy, community reinforcement, and other structured approaches can complement it.

Complementary approaches include acupuncture and hypnosis. Some people use complementary approaches for relaxation, stress, or other recovery-related symptoms. NCCIH’s review describes possible benefits of acupuncture as an adjunct for symptoms such as craving or anxiety. Discuss the intended goal, provider qualifications, and how a complementary approach fits alongside the rest of treatment.

Medications and vaccine research

No medication is FDA-approved specifically for cocaine use disorder. The ASAM/AAAP guideline discusses selected off-label options, including bupropion in some circumstances. Medication choices require an individual assessment, including other health conditions and substance use.

N-acetylcysteine, baclofen, and bupropion have been investigated as potential medications for cocaine use disorder. Work on drug-targeting vaccines, including research associated with Kim Janda and other teams, has also explored whether antibodies can reduce cocaine’s access to the brain. NIDA’s research overview describes cocaine-vaccine development as an investigational approach.

A cocaine vaccine is not a routine treatment available to prevent an overdose today. People seeking help can act now through behavioral treatment, medical and mental-health care, and continuing recovery support.
