Cocaine never left the public health picture — but fentanyl has made it significantly more dangerous. In 2023, nearly 29,000 U.S. overdose deaths involved cocaine, according to the CDC. The good news is that cocaine-involved overdose deaths fell sharply in 2024, matching the broader decline in drug overdose fatalities that year. The harder reality: a large share of those deaths involve fentanyl in the cocaine supply, and many people who use cocaine have no idea it's there. Understanding the risk — and the tools that reduce it — can save lives.
According to CDC data, cocaine was involved in nearly 29,000 drug overdose deaths in the United States in 2023. The age-adjusted rate of cocaine-involved deaths dropped by roughly 27% from 2023 to 2024 — from 8.6 deaths per 100,000 people to 6.3 — mirroring a nationwide decline in overall overdose mortality. That broader decline, from about 110,000 deaths in 2023 to just over 79,000 in 2024, was the largest single-year drop on record.
The decline is real and worth recognizing. But even at its lower 2024 level, cocaine remains one of the most lethal drugs in the U.S. illicit supply — and the contamination of that supply with fentanyl has fundamentally changed who is at risk.
Illicitly manufactured fentanyl — the synthetic opioid driving the modern overdose crisis — is now routinely found mixed into cocaine, often without the buyer's or user's knowledge. Drug dealers may add fentanyl to increase the apparent potency of their product, or it may be introduced through shared equipment and cutting agents.
This creates a specific danger: people who use cocaine typically have no opioid tolerance. That means even a small amount of fentanyl — which is roughly 50 times more potent than heroin — can cause a fatal overdose in someone who has never used opioids before. The person may believe they are only using cocaine, feel normal warning signs of cocaine use, and then rapidly lose consciousness as the opioid takes effect.
Fentanyl test strips (FTS) are a low-cost, evidence-based tool for detecting fentanyl in a drug sample before use. SAMHSA recognizes their distribution as a key component of overdose prevention, and many local health departments, syringe service programs, and harm reduction organizations make them available for free. Checking a sample before use cannot eliminate all risk, but it can alert a person that fentanyl is present so they can take precautions.
Cocaine and opioid overdoses can look different, but when fentanyl is involved, the opioid signs typically dominate:
If a person is unresponsive or has stopped breathing and cocaine may be involved, treat it as an opioid overdose — call 911 immediately and administer naloxone (Narcan) if available. Naloxone will not cause harm if opioids are not present, but it may be lifesaving if fentanyl is in the cocaine. Many communities now recommend that anyone who uses stimulants carry naloxone for exactly this reason.
Harm reduction does not require a person to stop using substances — it meets people where they are and helps reduce the risks they face. For people who use cocaine, practical steps include:
One of the most important things to know about cocaine use disorder is that, unlike opioid use disorder or alcohol use disorder, there is currently no FDA-approved medication to treat it. Research into potential pharmacological treatments is ongoing, but as of now, the most effective approaches are behavioral — and they work well for many people.
Contingency management (CM) is the most evidence-supported treatment for stimulant use disorders, including cocaine. In CM programs, people receive vouchers, prizes, or other small incentives for negative drug tests or for staying engaged in treatment. Multiple clinical trials and real-world programs have shown that CM significantly reduces cocaine use and improves treatment retention. SAMHSA officially recognizes contingency management as an evidence-based practice for stimulant use disorders.
Cognitive-behavioral therapy (CBT) teaches people to recognize the people, places, emotions, and situations that trigger urges to use, and to develop concrete coping strategies. CBT helps build skills that support long-term recovery — including how to handle cravings, manage stress, and solve problems without turning to substances.
Both of these approaches are available in outpatient and residential treatment settings. To find a program near you, call SAMHSA's National Helpline or use their online treatment locator — both are free, confidential, and available 24 hours a day.
