How Long Does a Cocaine High Last?

The length of a cocaine high varies based on factors like how it’s taken and the amount consumed, but it generally endures for about 15 to 30 minutes.

Healthline does not support the illegal use of any drugs. We do, however, aim to provide clear and accurate information to help minimize harm when these substances are used.

Compared with many other drugs, cocaine’s effects are relatively brief. A standard cocaine high usually lasts roughly 15 to 30 minutes, depending on the route of administration.

Some users report residual effects lasting for several hours after use, and the comedown phase can persist for a few days.

The onset is often rapid and intense, which contributes to cocaine’s high addiction risk despite the short duration of its pleasurable effects.

What does a cocaine high feel like?

Cocaine produces a short-lived euphoric state that may cause a person to feel elated, energized, more self-assured, and outgoing. Some anecdotal reports even suggest a perceived boost in creativity for certain users.

These sensations arise because cocaine affects dopamine circuits in the brain’s reward system. Using cocaine gives the brain a brief surge of stimulation by increasing dopamine availability.

That said, some individuals experience heightened anxiety, panic, or paranoia after taking cocaine, according to a National Institute on Drug Abuse report.

Ultimately, acute effects differ among people and depend on dose and how the drug is consumed.

How long does a cocaine high last?

As mentioned, the duration hinges on the method of use and other variables. Routes that deliver cocaine to the bloodstream more quickly also tend to produce briefer highs.

Typical durations by route are:

• Snorting:15 to 30 minutes
• Gumming: 15 to 30 minutes
• Smoking: 5 to 10 minutes
• Injecting: 5 to 15 minutes

Remember that intensity and length vary between individuals. Some people may notice lingering effects for as long as 4 hours.

Amount used and concurrent use of other substances can also change how long the high persists.

After the high fades, many experience an uncomfortable comedown that can last several days, according to a 2017 DEA guide.

During the comedown, fatigue, restlessness, and irritability are common. Insomnia frequently follows cocaine use as well.

How long does it take to kick in?

Onset speed depends on the administration route. The faster a drug enters the bloodstream, the sooner its effects begin.

Snorting or chewing cocaine produces a slower onset than smoking or injecting because the drug must cross membranes and tissues before reaching circulation.

Typical onset times by method:

• Smoking or snorting:2 to 3 minutes
• Chewing or gumming: about 1 to 2 hours
• Injecting: within 5 minutes

How long can cocaine be detected?

Detection windows depend on the type of test used.

Common detection times by test:

• Urine:2 to 3 days
• Blood:up to 2 days
• Saliva: up to 2 days
• Hair: up to 3 months

Long-term effects of cocaine use

Over time and with repeated use, cocaine can damage your:

• lungs (if smoked)
• nasal passages (if snorted)
• digestive tract
• cardiovascular system
• brain and memory

However, a 2018 review indicates that linking cognitive impairments to chronic cocaine use may be problematic due to inconsistent data comparisons. The authors warn that this negative association could influence treatment planning and policy.

Regular use increases the likelihood of tolerance, which may lead to both physical and psychological aspects of addiction.

Healthline does not support the illegal use of any drugs. We do, however, aim to provide clear and accurate information to help minimize harm when these substances are used.

Safety tips

There is no truly safe way to use cocaine, but if someone chooses to use it, certain precautions can reduce some risks.

Consider these harm-reduction steps:

• Test it first. Cocaine is frequently adulterated with other substances, sometimes including stimulants or fentanyl, which can be deadly. You can buy cocaine testing kits from DanceSafe.org.
• Be careful with paraphernalia. Don’t share needles, pipes, or straws. Inspect equipment before use—look for cracks in pipes or chips in straws and ensure needles are sterile.
• Avoid mixing substances. Combining drugs greatly raises the chance of severe effects or overdose. Avoid using cocaine with other substances, including alcohol.
• Start low and slow. Use a small amount and avoid re-dosing quickly. Consider keeping only a limited quantity on hand during a session. Cocaine carries a strong risk for developing a substance use disorder; increased use raises dependence risk.
• Steer clear if you have heart issues. Avoid cocaine if you have high blood pressure or other cardiac conditions. The cardiovascular risks of cocaine are well documented, including heart attack risk even in otherwise healthy individuals.
• Don’t use alone. Have a trusted person nearby who can recognize signs of an emergency and get help if needed.

Cocaine overdose

Whether you’re using cocaine or are near someone who is, it’s crucial to recognize overdose signs.

Call 911 or local emergency services immediately if you or someone else displays any of the following:

• irregular heartbeat or pulse
• trouble breathing
• nausea and vomiting
• elevated body temperature
• high blood pressure
• chest pain
• hallucinations
• severe agitation
• seizures
• loss of consciousness

Don’t let concerns about law enforcement stop you from calling for help. You don’t need to describe the substances used—just report symptoms so responders can provide appropriate care.

If you’re caring for someone, place them in the recovery position: on their side with a bent knee supporting the body. This helps keep the airway clear and reduces the risk of choking if they vomit.

The takeaway

Cocaine intoxication is typically intense but short-lived. Despite the brief high, this stimulant carries a significant risk of addiction and overdose.

If you’re worried about your cocaine use, support is available. Talk with your primary care provider and be candid about substance use—doctor–patient confidentiality protects this information from law enforcement disclosure.

You can also:

• Call SAMHSA’s national helpline at 800-662-HELP (4357), or use their online treatment locator.
• Locate a support group through the Support Group Project.
• Find local meetings or resources from Narcotics Anonymous.
