How Long Does Cocaine Stay In Urine?

Using cocaine is illegal and very addictive. Cocaine misuse can cause problems in a person’s daily life. Cocaine affects most mentally, physically and emotionally. This article will goes over how long cocaine remains in the body.

Our body does not expel or excrete cocaine immediately. Instead, the cocaine will stay in your system for a certain period of time.

In general, cocaine or its metabolites will continue to show up on a urine test between two to four days after last using the drug. However, there are certain factors that can affect the answer to the question of, “how long does cocaine stay in urine?”

One of these factors is repeat or prolonged drug use. If you or someone you know is a heavy cocaine user, the drug can stay in your urine for much longer. It is possible to test positive in a cocaine urine test even up to two weeks after use.

Statistics on Cocaine Drug Abuse in the U.S.

Cocaine is a highly addictive stimulant drug derived from the leaves of the coca plant. It is classified as a Schedule II controlled substance. This means that while it can be used medically as a local anesthesia, it also has a very high potential for abuse.

Cocaine stats suggest millions of Americans are found to be using or have used cocaine within any given year. Back in 2020, a national survey from the U.S. Substance Abuse and Mental Health Services Administration (SAMHSA) showed that almost 2% or 5.2 million people over the age of 12 used cocaine in the year prior.

Not only that, but in 2021, researchers found that teenagers as young as 13 or 14 years old (8th graders) to 17 or 18 years old (12th graders) have been exposed to or have taken cocaine within the past year.

These concerning figures highlight two things. First is the importance of being vigilant in watching over impressionable adolescents. Second, is how crucial drug tests are to determine cocaine misuse before it turns into cocaine addiction or drug abuse.

Catching cocaine use early can help the individuals in question avoid severe cocaine withdrawal symptoms. More importantly, early detection is invaluable in ensuring successful cocaine addiction treatment.

How Long Does Cocaine Stay in Your System?

How long drugs stay in urine depends on the type of drug testing or screening method used, cocaine or cocaine metabolites can stay in your system for up to several months after using it.

Below are the average cocaine detection times based on the body fluid or sample used:

• Urine test — Cocaine stays in urine for up to four days.
• Blood or saliva test — Cocaine stays in blood or saliva for up to two days.
• Hair — Cocaine can be detected in our hair anywhere between a couple of months up to a few years.

Factors That May Affect Cocaine Detection Times

There are several other factors that affect cocaine detection times aside from repeat or prolonged cocaine abuse. Depending on these factors, it may extend or shorten the cocaine detection window.

Among these factors are:

• Cocaine purity
• Dosage, or how much cocaine was ingested
• Method of drug administration, such as snorting, gumming, or smoking cocaine
• Coke plus drinking alcohol
• Physical factors, such as height and weight
• Body fat content, as cocaine metabolite are stored in the fatty tissue
• High blood pressure or low blood pressure
• Increased systolic blood pressure (can increase the risk of strokes, heart disease and chronic kidney disease)
• Metabolism
• Kidney disorder or liver disease
• Other pre-existing medical conditions
• Urine pH level
• Drug test or screening method

Different Cocaine Screening Methods and Drug Tests

Cocaine has a half-life of only around one hour. This means that an hour after using cocaine, the drug’s active substance that entered the bloodstream will already be reduced to half of the starting dose.

Because of cocaine’s short half-life and the body’s rapid processing of cocaine, drug tests instead measure cocaine’s metabolites. Metabolites are the by-products or the compounds that remain after the body has broken down or processed the drug or alcohol we ingested.

Drug tests used to detect cocaine in your system include:

Urine Drug Test

A urine test is the most common screening method. Individuals suspected of using cocaine are asked to urinate in a cup. The sample collected is then sent to a lab to be screened for benzoylecgonine, cocaine’s main metabolite.

Rapid urine tests are available and often ready within minutes, but these do not offer the same level of accuracy as lab tests.

Urine tests have a disadvantage, though. Perhaps due to its common use, there have been products advertising or claiming to help cocaine users flush cocaine, out of system, to alter urine drug test results. These products are often meant to be added into the urine to create a false negative drug test result.

Blood Test

The blood flow only retains cocaine for up to 12 hours maximum. However, benzoylecgonine can be detected in your blood for up to 48 hours or two days. Due to its invasive nature and long wait time for results, blood tests are not as common as urine or saliva tests. These drug tests are often only conducted in hospitals or similar medical facilities.

Saliva Test

Similar to blood tests, a saliva drug test can detect cocaine or its metabolites for only one to two days after it was used. A medical professional or tester typically collects the saliva sample using a special swab or device. This is then deposited quickly and directly into a tube to protect the sample. Thanks to this, saliva tests can be more secure or more difficult to cheat than urine tests.

Hair Test

Hair cocaine tests may be the most complicated out of all popular drug test options. However, a hair sample or specimen will offer the largest cocaine detection windows. Depending on the length of the hair specimen or shaft, the test can reveal cocaine metabolite even several months after use. Moreover, segmental hair analysis can be conducted to reveal detailed month-to-month drug exposure or patterns of cocaine use.

How Long It Takes for Cocaine’s Effects to be Felt

Cocaine’s onset of effects or the time it takes for its effects to be felt are almost immediate.

Since it is a stimulant, taking cocaine and/or crack cocaine in small amounts can make people feel the following:

• Euphoric
• Talkative
• Energetic
• Mentally alert
• Hypersensitive

The faster the body absorbs cocaine, the more intense the cocaine affect is, resulting high or stimulating effects. In general, snorting cocaine offers the slowest onset but a longer duration of effects.

Meanwhile, smoking cocaine offers immediate onset but a shorter duration, often no longer than 10 minutes.

Short-Term Effects of Cocaine Use

A person doesn’t have to struggle with cocaine addiction or abuse to experience its negative effects. Occasional or casual cocaine use can still lead to short-term adverse effects, particularly if the amount smoked or ingested are considerable.

Short-term effects of cocaine use include:

• Intense euphoria
• Constricted blood vessels
• Higher body temperature
• Increased heart rate and blood pressure
• Dilated pupils
• Nausea 
• Restlessness
• Anxiety
• Paranoia
• Hallucinations 
• Irritability
• Vertigo
• Tremors or muscle twitches
• Abdominal pain and gastrointestinal complications
• Appetite loss
• Sleep problems

These effects may also lead to various medical complications, particularly cardiovascular and neurological effects.

Examples of such complications include: cardiac arrests, seizures, strokes, or comas.

Lasting Impact and Dangers of Cocaine Use

What is considered heavy cocaine use? Regular or repeated cocaine use raises the risk of drug dependence. This, in turn, can lead to substance abuse and addiction. Heavy and prolonged use of cocaine exposes you to many risks and dangers, many of which can leave a lasting negative impact in your and your loved ones’ lives.

Cocaine notably affects our brain. As such, prolonged use can permanently alter your brain functions, including those related to problem solving, decision making, memory, attention, and even movement. It may also lead to the following:

• Cerebral atrophy or shrinking of the brain
• Transient ischemic attacks or mini strokes
• Cerebral vasculitis or inflammation of blood vessels in the spine and brain

Some long-term effects of cocaine use are similar to its short-term effects, though more intense.

Examples of these include irritability, panic attacks, paranoia, and hallucinations. In some cases, these effects may lead to a full-blown psychosis, where the person loses all sense of or touch with reality.

Other long-term effects of cocaine include:

• Permanent damage to heart blood vessels
• Arrhythmia or tachycardia
• Liver and kidney damage
• Damaged or destroyed tissues in the sinuses
• Respiratory failure, in cases of smoking cocaine
• Higher risk of pneumonia and tuberculosis
• Severe tooth decay
• Malnutrition
• Weight loss
• Mood disturbances
• Severe depression
• Disorientation
• Infertility or other reproductive and sexual problems
