Cocaine is a powerful central nervous system stimulant that is highly addictive. Like other drugs, when you use cocaine, it will take some time to work its way out of your system. As a result, its metabolites can show up on a drug test.

Many factors influence how long it takes for cocaine to be fully eliminated from your body, but here’s how long it can show up on a drug test:

• Urine test - up to 3 days after the last use (up to 2 weeks for heavy cocaine users)
• Blood test - up to 2 days after the last use
• Saliva test - up to 2 days after the last use
• Hair test - several months (or even years)

To more fully answer the question, “How long does cocaine stay in your system?” we’ll explore the influential factors and provide more details about how cocaine affects your body below.

The duration of the high depends on how the cocaine was used (whether it was smoked, taken orally, snorted, or injected). The faster the cocaine is absorbed, the more intense and short the high will be.

For example, smoking cocaine produces an immediate high that can last anywhere from five to 10 minutes. On the other hand, taking cocaine orally will result in slower effects that are felt within 10 to 30 minutes but that can last for up to 90 minutes.³

After the high (or rush), cocaine users experience a crash. The crash is extremely unpleasant so many people use more cocaine to counter the crash, which can lead to tolerance and addiction.

Determining exact detection times for cocaine use is difficult because there are several factors that affect how long cocaine stays in your body. Some of the most influential factors include:

• How often you use cocaine: Research indicates that large amounts of cocaine taken over a period of several days will cause its metabolites to linger in your body longer. Therefore, it will be more easily detected by drug tests.
• How potent the cocaine is: The purity level of the cocaine you use will affect how quickly its metabolites are eliminated from your body.
• The method in which you use cocaine: The method of cocaine use (snorting, smoking, injecting, etc.) will greatly affect its detection window. Generally speaking, the faster the drug is absorbed into your bloodstream, the faster it will be excreted from your body. So, for example, if you smoke cocaine, it will clear out of your system faster than if you consumed cocaine orally.
• Your body fat level: If you have higher levels of body fat, benzoylecgonine can build up in fatty tissues and stay in your body longer than in someone who has fewer fatty tissues.
• How hydrated you are: Water speeds up the excretion process, getting rid of cocaine metabolites faster. If you are dehydrated, this process will occur more slowly, which means the drug may remain detectable in your system for longer.
• How physically active you are: If you are physically active, your basal metabolic rate (BMR) will be higher. (BMR is a measure of the number of calories your body needs to accomplish its most basic functions, like breathing.) Cocaine is excreted more quickly in people with higher BMRs.

Once you’re addicted, quitting cocaine can be very difficult. This is especially true if you’re a heavy user. In fact, if you try to stop using it, you’re likely to experience uncomfortable cocaine withdrawal symptoms like:⁵

• Anxiety
• Irritability
• Difficulty sleeping
• Depression
• Sadness
• Cocaine cravings
• Poor concentration
• Lethargy

These symptoms can occur a few hours or a few weeks after you stop using cocaine. Although not everyone experiences severe cocaine withdrawal symptoms, some people do. Inpatient detox is not always necessary for cocaine detox but it can be helpful in some instances.

For example, if you’re addicted to cocaine and other drugs, a detox program can provide 24/7 medical assistance to prevent medical emergencies due to unpredictable withdrawal symptoms. Medical professionals will also administer medications to keep you comfortable and safe during detox. Additionally, a cocaine detox program will provide access to other treatment services like:

• Initial physical and psychological health assessment (this can help identify co-occurring disorders)
• Individual and group counseling
• H&I meetings
• Referrals for ongoing treatment

If you're asking how long cocaine stays in your system, you're likely facing a drug test, concerned about withdrawal, or seeking help for yourself or a loved one. Understanding detection windows is an important step—but it's just one piece of the recovery puzzle.

At Briarwood Detox Center in Austin, TX, we provide medically supervised cocaine detox designed to help you safely navigate withdrawal and begin your recovery journey with expert support.

Updated Cocaine Detection Times by Test Type (2025)

• Urine: 2–4 days for occasional users; up to 2 weeks for heavy or chronic users
• Blood: 12–48 hours
• Saliva: 1–2 days
• Hair follicle: Up to 90 days (sometimes longer with heavy use)

Detection windows vary based on frequency of use, metabolism, body mass, hydration, and the purity of the cocaine used. Benzoylecgonine, the primary metabolite, is what most tests detect—and it lingers longer than cocaine itself.

Why Cocaine Detox Requires Medical Supervision

While cocaine withdrawal is not typically life-threatening, it can be intensely uncomfortable and emotionally destabilizing. Symptoms include:

• Severe fatigue and hypersomnia
• Depression, anxiety, and irritability
• Intense cravings
• Increased appetite
• Difficulty concentrating

At Briarwood Detox Center, our board-certified physicians and addiction specialists monitor you 24/7, manage symptoms with evidence-based protocols, and provide a safe, supportive environment to help you stabilize physically and mentally.
