How Long Does Crack Stay in Your System?

Various substances stay in the body for different amounts of time. This is a common area of concern for drug detox treatment programs as well as for individuals who need to take a drug test for a job. It’s important to keep in mind that drugs and alcohol stay in different parts of the body (hair, saliva, urine, etc.) for different amounts of time. When it comes to using crack cocaine, many specific questions and topics arise, including:

  • How long does crack stay in your system?
  • How long does crack cocaine stay in your system?
  • How long does crack stay in your urine?
  • How long does crack cocaine stay in your urine?
  • How long does coke stay in your saliva?
  • How to get crack out of your urine
  • How to get crack out of your system

Depending on how much is used, crack cocaine can be detected in the blood up to two to 12 hours after use. Crack cocaine’s half-life is only 15 minutes. However, there are several factors that can influence how long crack cocaine can be detected through the following drug tests:

  • Crack cocaine can be detected in hair follicles up to three months after use, but can still yield positive results after several years.
  • Crack cocaine is typically detected in the urine for one to four days after use, but can be detected several weeks after use.
  • Crack cocaine can be detected in saliva for up to 24 hours after use.

It is known that cocaine is a dangerous and popular drug. But crack cocaine, a derivative of cocaine, poses its own problems for users. The drug provides a quick and strong high, but can become quickly addictive and remain traceable in the body for years. In order to understand how the body reacts to and processes crack cocaine, it is important to first understand what the drug is.
Crack cocaine is a form of cocaine from which the hydrochloride is removed, making the drug more potent in a rock crystal form. In this form, also known as “freebase cocaine,” the crystal is smoked.  When it’s heated, the rock crystal makes a cracking sound, which is why it is often referred to as “crack.”

Crack cocaine is a stimulant, and can bring about a fast, strong high during which mental and physical processes in the body are sped up. Other names for crack include dice, pieve, rocks, base and cookies.

Like many drugs, crack cocaine works by affecting the brain’s neurotransmitters. More specifically, it affects the neurotransmitters that control emotions and feelings of pleasure. Using crack causes dopamine to build, which causes the user to feel pleasure quickly. However, over time the body will become used to crack cocaine and the used will find that it requires more of the drug in order to reach the same level of a high. This is how use escalates and often becomes out of control.

Since crack cocaine is a stimulant, it causes body mechanisms to speed up. Users often speak quickly and seem jumpy or twitchy. The drug can affect the speed of a user’s heart beat, which is a danger. When the body eventually begins to rid itself of crack cocaine, the user often crashes and becomes very tired.

Crack cocaine has several short term effects, including impaired judgement, hallucinations, and sleep disturbances. However long-term use of cocaine can also lead to several long-term health effects, such as:

  • Cognitive impairments
  • Increased risk of infection
  • Damage to the central nervous system
  • Damage to the cardiovascular system
Since crack cocaine is smoked, it is quickly absorbed into the lungs. Crack produces a very short high — sometimes only five to 10 minutes long. The half life of the drug is short, at only 15 minutes. This means that 15 minutes after use, only half the amount of the drug would remain detectable in the body. However, this timeframe varies for every individual and depends on a number of additional factors, such as:
The liver is the main organ that works to metabolize crack cocaine in the body, by breaking it into smaller compounds. Depending on how well the liver functions, this may take longer for some users than it would for others.
This affects how long the drug remains in the body because if a user has been abusing the drug for a long period of time, it has likely built up in parts of the body. Because of this, it will take longer for the drug to be completely flushed from the system.
If a drug is used at or near the same time as food is eaten, the process of breaking down the drug can be slowed. This is because the rate at which the body can absorb and break it down is delayed, since the body is also working to break down food. On the flip side, fluid intake can speed up the rate at which a drug is metabolized, since it increases urine output.
The amount of crack cocaine used and the frequency with which is it used affects the rate at which the body can metabolize it. If someone smokes crack cocaine every day and does so in large quantities, the drug is more likely to build up in the body, taking longer to be metabolized and ridded. But if someone is a one-time user of the drug and uses a small amount, it will be cleared from the body much more quickly.
If a crack cocaine user is on other medications or drugs, the time it takes for the body to metabolize crack cocaine can be delayed or sped up. Which circumstance depends on the other drugs being used and the frequency of use, as well as how closely they are used to when crack cocaine was smoked.

Although the high created by crack cocaine is short, it can be detected in the body for quite some time after use through a variety of testing methods. Often use is detected by the metabolite benzoylecgonine, rather than the presence of the drug itself.

There are various forms of testing for crack cocaine that can help you learn more about how to get crack out of your urine or how to get crack out of your system. They can also address the following questions:

  • How long does crack stay in your system?
  • How long does crack cocaine stay in your system?
  • How long does crack cocaine stay in your urine?
  • How long does crack stay in your urine?
This is the testing method least likely to detect use of crack cocaine, unless blood is tested within a few hours of use. Depending on a user’s metabolism and the dose of the drug they took, blood can be clear in as little as two hours, and sometimes up to 12 hours.
Unlike blood testing, hair testing can detect crack cocaine for a very long time after the use. The substance and its metabolites (a product created when the body metabolizes a drug) can be detected in hair follicles, and because hair grows so slowly, it can remain detectable for years.
How long does crack stay in urine? Though it gives a larger window of time than blood testing, crack cocaine is only detectable in urine for one to four days after it is used. Like other testing methods, the exact amount of times depends on the amount the user has used, the rate the body metabolizes and the frequency of use, among other factors. In some cases, if an individual has been abusing crack cocaine for a long period of time, it can remain detectable in urine for weeks.
How long does coke stay in your saliva? Like blood testing, saliva testing only allows for a short window of time, as traces of the drug are usually gone from saliva within 24 hours of use.

Since each person who uses crack cocaine has a different body and different history with the drug, it is difficult to estimate about how long the drug can remain traceable. In order to best form an idea of this timeframe, all the above factors must be taken into consideration.
