What you will learn:

  • How long crack cocaine is detectable in urine depends on several factors
  • The drug is detectable using several types of tests, some with longer detection windows than others
  • Crack cocaine remains in the system after the affects of the drug have worn off

When you begin your recovery journey, the desire to be completely clean and clear of any substances is strong.

One of the most common tests to determine whether or not crack cocaine is still in your system is a urine test.

Crack Cocaine Urine Detection Time.

How long crack cocaine stays in urine depends on several factors, including the length of time you’ve used the drug, the amount of the drug consumed, the sensitivity of the test, your individual metabolism, and your overall health.

On average, crack cocaine is detectable in urine from 3-5 days [1] after last use.

For those who are heavy users, crack cocaine can be detected in urine for up to a week or more.

Crack cocaine can be detected in urine even after just a one-time use of the drug.

What Factors Can Affect How Long Crack Cocaine Stays in Your Urine?

Several factors affect how long crack cocaine can be found in urine, including dosage, frequency of use, metabolism, hydration status, body mass and composition, age, health status, and how the sample is collected and handled.

Let’s take a deeper look at each:


The amount of crack cocaine used can affect how long it stays in urine. Taking higher doses of the drug will result in a positive test for a far longer period. However, it is important to keep in mind that although the detection window may be smaller, even trace amounts of the drug can be detected through a urine test.

Frequency of Use

How frequently an individual uses crack cocaine can affect urine detection time. When substances are ingested, they are metabolized and broken down into different compounds, which are excreted from the body in various ways, including urine.

For frequent users, these metabolites may accumulate in the body over time, resulting in a longer detection time.


Everyone metabolizes substances at different rates. For some crack cocaine users, the drug may be eliminated from the body relatively quickly, while for others, it may take longer to be completely out of the system.


Someone who is well-hydrated may eliminate crack cocaine from their system faster than a dehydrated person, as the substance is excreted through the urine.

Body Mass and Composition

Metabolite from crack cocaine can be stored in fatty tissues. Those with a higher body fat percentage may eliminate these metabolites more slowly. Muscle has a higher metabolic rate than fat tissue, so those with a higher percentage of muscle mass may process and eliminate crack cocaine more quickly.


Age-related factors such as changing body composition and decline in liver or kidney function play a role in how long crack cocaine is detectable in urine. Older adults often eliminate drugs slower than younger adults

Health Status and Medications

Certain health conditions, especially those that affect the functionality of the kidneys or liver, and certain medications can affect drug metabolism and elimination.

Urine Sample Collection and Handling

Urine Sample Collection and Handling

Although how the sample is handled doesn’t have any impact on how long the crack cocaine actually stays in urine, Improper collection or handling of samples can affect detection. Contamination, dilution, and improper temperature control can impact the integrity of the sample and lead to false results.

Note that these factors are not the only ones that affect how long crack cocaine is found in the urine.

It typically takes 1-2 hours for crack cocaine to appear in urine after use. However, if the dosage taken was lower, it may be slightly longer.

How Accurate are Urine Tests for Crack Cocaine?

Urine tests for crack cocaine are generally considered to be highly accurate. The accuracy of these tests depend on the sensitivity and specificity of the test, the quality of the sample collected [2]. A laboratory test is generally more accurate than an at-home test.
How Do You Get Crack Cocaine Out of Your System Quickly?
There is no guaranteed method for getting crack cocaine out of your system quickly. However, while detoxing from the drug, staying hydrated, eating a nutritious diet, physical exercise, and abstaining from the drug will help with the detoxification process.

It is important that you detox from crack cocaine or any other drug under the supervision of a medical professional, as doing so on your own can lead to adverse–and sometimes fatal–side effects.

Can Crack Cocaine Be Detected In Urine Even After The Effects Wear Off?

Yes. Crack cocaine can be detected in urine for up to several days after the “high” effects of the drug wears off. And, as you’ve seen in the information provided above traces can be shown in things like hair follicles [3] and more.

Frequently Asked Questions About Crack Cocaine Detection

As a drug rehab center, we are often asked questions about how long crack cocaine stays in urine. We’ve answered some of the most frequently asked questions below.

There are a variety of tests that can detect crack cocaine besides urine tests. Other commonly used methods to test for crack cocaine use include blood tests, saliva tests, and hair tests, although these tests are not as commonly used as urine tests.

It can take up to several days for crack cocaine to leave the body completely. How quickly the drug is fully eliminated depends on several factors such as dosage, metabolism, and frequency of use.” image-1=”” headline-2=”h3″ question-2=”Can Secondhand Crack Cocaine Smoke Be Detected In A Urine Test?

A positive drug test as a result of secondhand crack cocaine smoke exposure is unlikely. The drug typically needs to be directly ingested to produce metabolites that are detectable by standard drug tests.

No. Crack cocaine is typically eliminated from the body within a few days. However, other drug tests, such as a hair follicle test, can detect crack cocaine use up to 90 days prior.

Yes. Crack can be detected in urine for up to several days after the “high” effects of the drug wears off.
