After last use, cocaine or its metabolites typically can show up on a blood or saliva test for up to 2 days, a urine test for up to 3 days, and a hair test for months to years. A heavy user can test positive on a urine test for up to 2 weeks.
But other factors can influence how long it stays in someone’s body, such as metabolism, weight, dose, and frequency of use. Drinking while taking cocaine may also slow its elimination from the body.

Injecting or smoking cocaine can cause a rush, which is then followed by a high, whereas other modes of use only cause a high. It is common for individuals to use cocaine over and over again in a short time period to stay high, also known as a binge. Binge use is often followed by an unpleasant crash. The crash may lead them to seek more of the drug to counter the crash. Repeated cocaine use can easily lead to an increased tolerance and even addiction.
According to the National Survey on Drug Use and Health, about 966,000 people in the United States age 12 and older met the criteria for a cocaine use disorder—more commonly referred to as a cocaine addiction—in 2017.
Cocaine Half-Life
Cocaine’s half-life is roughly one hour.4 This means that it takes about an hour for the body to eliminate half of the cocaine currently in the bloodstream.7 However, long-term use may lead to longer elimination times, allowing certain tests to detect the drug in the system for an extended period.
How Long is Cocaine in Your System?
Detection timeframes for different types of tests are listed below:
| Body System | Time in System |
|---|---|
| Blood | Up to 2 days |
| Saliva | Up to 2 days |
| Hair | Months to years |
| Urine | Up to 3 days, but up to 2 weeks for heavy users |
- Cocaine or its metabolites typically can be detected in the blood and the saliva for up to 2 days after the last use.9
- It may be detectable in a hair sample for months to years.10
- Its metabolites can usually be detected in urine for up to 3 days, but it can remain detectable for up to 2 weeks in heavy users.9
Despite the different testing methods available, urine toxicology screening remains the most commonly used method of testing.9
Anyone who is concerned about testing positive for cocaine should review the dangers of cocaine use and consider stopping use. If they find they are unable to stop using, they may have a cocaine use disorder.
Those who struggle with cocaine addiction should seek substance use treatment as soon as possible.

How long does cocaine stay in your system?
Cocaine typically stays in your system for 1 to 4 days, but it can be detected for up to a couple of weeks in some people.
How long it hangs around and how long it can be detected by a drug test depends on several factors.
Here’s a look at typical detection times by test type:
- Urine: up to 4 days
- Blood: up to 2 days
- Saliva: up to 2 days
- Hair: up to 3 months
How long does it take to feel the effects?
Coke is one of those drugs that hits you hard and fast, but the exact onset time depends on how you consume it.
If you snort or gum cocaine, you feel the effects within 1 to 3 minutes. If you smoke cocaine or inject it, you’ll feel effects in a matter of seconds.
The time difference comes from the speed at which it enters your bloodstream.
When snorted or gummed, the drug has to get through mucus, skin, and other tissues first. Smoking and injecting it bypasses all that and gets it into your bloodstream almost instantly.
How long do the effects last?
How you consume it determines how long the effects last, too.
The high from snorting or gumming coke generally lasts from 15 to 30 minutes. If you smoke or inject it, the high lasts roughly 10 to 20 minutes.
Keep in mind that the duration and intensity of the effects aren’t the same for everyone.
Some people can feel the effects for as long as an hour. How much you use and whether you’re also using other substances can make a difference, too.
What factors affect detection time?
According to the Drug and Alcohol Testing Industry Association (DATIA), cocaine can usually be detected for 2 to 10 days.
Keep in mind that’s a general window. Detection times can vary depending on several factors, including:
- Test type. Drug tests work by detecting metabolites, which are byproducts your body produces as it breaks down substances. Some metabolites stay in your system longer than others, so the detection window will depend on which metabolites are being tested.
- How much you use. As with any substance, the more cocaine you use, the longer it’ll stay in your system.
- How often you use it. The more often you consume cocaine, the longer the detection window.
- How you use it. Cocaine that’s snorted or gummed will remain in your system longer than if you smoked or injected it.
- The purity level. Cocaine often contains contaminants or other substances, which can affect how long it stays in your system.
- Your body composition. Benzoylecgonine, cocaine’s main metabolite and the one that’s most often tested for in drug screening, can be stored in fatty tissue. The higher your body fat, the more cocaine metabolites can accumulate in your body.
- Drinking alcohol. Combining alcohol and cocaine can cause certain cocaine metabolites to stick around in your system longer.
