Cocaine Drug Testing

There are various types of cocaine drug testing kits. In this article we explore the pros and cons of the various tests that you can buy from UK drug testing companies. Understanding which testing method suits your needs—whether for workplace compliance, personal peace of mind, or legal requirements—is essential for getting accurate, timely results.

Even if you only use cocaine once, traces can remain in your system for as long as 90 days, depending on the type of testing being employed. The most commonly used method is urine testing, as it is the least expensive. This particular testing method is used by everyone from schools and employers, all the way up the court system. Not only is urine testing relatively inexpensive, it also delivers results of recent cocaine use quickly and accurately.

Cocaine is often viewed as the drug of choice for the rich and famous, but its use is becoming more prevalent in all classes. In Britain alone, 2% of the population regularly use cocaine, which is about the same level as in the US.

Effects of Cocaine and Crack Cocaine

The dose and how quickly the cocaine enters the brain are what determines intensity.

When cocaine is snorted, it reaches the brain in about 3–5 minutes. Intravenously injecting the substance cuts that time down to between 15 and 30 seconds, whereas smoking delivers an experience that is almost immediate. The trade-off comes in the length of the high, with faster absorption leading to a shorter high time. For example, smoking delivers a 5–10 minute high, while snorting will keep a user high for 15–30 minutes.

The after effects of the high is known as a “coke crash” and can include symptoms such as tiredness, irritability and depression. Frequent doses need to be taken if withdrawal is to be avoided.

Paranoia is a common side effect that comes with long-term use of cocaine at a high dosage. When smoking crack cocaine, that paranoia can quickly turn aggressive. Depression is common among addicted cocaine users who kick the habit. The mucous membrane of the nose can become negatively affected with prolonged snorting.

The Psychological Impact of Cocaine Use

Cocaine doesn’t just affect the body—it rewires your brain’s reward system. Each use can create powerful psychological dependencies that extend far beyond the immediate high. Users often experience intense cravings that override rational thinking, making addiction a complex psychological battle. The drug’s impact on dopamine levels can fundamentally alter mood regulation, leading to significant mental health challenges. What might start as occasional recreational use can quickly transform into a destructive cycle of psychological and physiological dependence, trapping individuals in a dangerous pattern that’s incredibly difficult to break.

The History of Cocaine

Cocaine is a stimulant drug derived from the coca plant native to South America. Indigenous peoples in the Andean region have chewed coca leaves for centuries for their mild stimulant effects.

Pure cocaine was first isolated in the mid-19th century. In 1859, German chemist Albert Niemann isolated cocaine from coca leaves. In the late 19th century, cocaine emerged as a popular ingredient in tonics, elixirs, wines, and “medicines” touted to cure a variety of ailments. Famous psychoanalyst Sigmund Freud praised cocaine for its perceived benefits and even wrote a paper called “Über Coca” in 1884.

The addictive nature of cocaine soon became apparent. In the early 20th century, many Western countries banned the sale of products containing cocaine. However, cocaine remained popular as an illicit recreational drug through the 1970s. Usage declined in the 1980s as the harmful effects of the drug became more widely known. Understanding this history helps contextualise modern workplace cocaine testing requirements and public health responses.

The Rise of Crack Cocaine

In the 1970s and 1980s, a smokable form of cocaine emerged called “crack” or “rock” cocaine. Crack offered a faster, more intense high than snorting powdered cocaine. However, the effects of smoking crack only last 5–10 minutes, leading to compulsive re-dosing and addiction.

Crack cocaine wreaked havoc in cities across the United States in the 1980s and 1990s. The crack epidemic hit poor, predominantly African American urban neighbourhoods the hardest. At the peak of the crack epidemic in the late 1980s, over 1 million Americans were addicted to crack cocaine.

In 1986, the US Congress passed the Anti-Drug Abuse Act, which instituted harsh mandatory minimum sentences for crack possession and dealing. Critics argued the crack sentencing disparity unfairly targeted African Americans. The Fair Sentencing Act of 2010 reduced the sentencing disparity between crack and powder cocaine possession from 100:1 to 18:1.

Health Effects of Cocaine

Cocaine is an extremely addictive substance that can cause both short-term and long-term health effects:

Cocaine Drug Testing: Which Method?

Testing for cocaine use is usually done in one of three ways: urine, saliva and hair. Using those methods, cocaine can be detected for periods of 1–3 days, 12–48 hours and up to 90 days respectively. Your choice of method depends on your testing context, budget, and detection window requirements.

Urine Testing for Cocaine

Urine Testing: Pros and Cons

Urine drug testing is the most common method for detecting cocaine use across UK workplaces, schools and law enforcement. Cocaine metabolites can be detected in urine for 1–3 days after last use for most users. Heavy users may have cocaine metabolites detectable in urine for 7–10 days or longer.

How Urine Cocaine Tests Work

Urine cocaine tests work by detecting the cocaine metabolites benzoylecgonine and ecgonine methyl ester. Most urine drug tests have a cutoff level of 300 ng/mL for a positive cocaine test. This means a urine sample must contain at least 300 nanograms per milliliter of benzoylecgonine and/or ecgonine methyl ester to test positive for cocaine. Understanding drug test cut-off levels for cocaine is important for both employers and individuals.

Step-by-Step Guide to Administering a Urine Cocaine Test

1. Collect urine sample: The test subject provides a fresh urine sample into a clean specimen cup, minimum 45mL.
2. Transfer sample: Using the provided dropper, the tester transfers urine from the specimen cup into the sample well on the test cassette. Enough urine (2–3 drops) must be transferred to contact the reagent strip inside the well.
3. Wait for results: The tester waits 5 minutes as the urine travels up the reagent strip inside the cassette.
4. Read the result: At the end of 5 minutes, the tester checks the indication window next to the “C” (cocaine) line.

Understanding Your Urine Test Results

Proper interpretation of the urine cocaine test results requires training and an understanding of the testing limitations. False positive results, though rare, can occur due to cross-reactivity or sample contamination. Other substances in the urine can also affect test performance. Valid negative results require the subject to abstain from cocaine use for at least 1–3 days before testing.

Saliva Testing for Cocaine

Saliva Testing: Pros and Cons

How Saliva Cocaine Tests Work

Saliva drug testing is an emerging method to detect recent cocaine use. Cocaine and its metabolites can be detected in saliva for 12–48 hours after last use. Saliva testing is better at detecting very recent cocaine use compared to urine testing.

Saliva cocaine tests work by detecting the presence of the parent drug itself, not metabolites as in urine tests. Most saliva cocaine tests have a cutoff level of 20–50 ng/mL. This means a saliva sample must contain at least 20–50 nanograms per milliliter of cocaine for a positive test result.

Step-by-Step Guide to Administering a Saliva Cocaine Test

1. Prepare for collection: The test subject rinses mouth with water 10 minutes before test. No food or other objects should be in mouth.
2. Collect sample: The tester or subject gently rubs the collection pad on the inside of the cheek and under the tongue to collect saliva. Enough saliva is needed to activate the indicators on the collection pad.
3. Insert into cassette: The collection pad is inserted into the test cassette. The tester times 5 minutes.
4. Read the result: At 5 minutes, the tester checks the indication window next to the “C” (cocaine) line.

Understanding Your Saliva Test Results

Proper saliva collection technique is important to get an adequate sample. Food, blood, or other contaminants can affect results. Saliva cocaine tests are qualitative, giving a positive or negative result only. Quantitative confirmation requires laboratory analysis.

Saliva tests are increasingly used in workplace drug screening programs. For more information on workplace testing procedures, visit ACAS (Advisory, Conciliation and Arbitration Service), which provides guidance on UK workplace drug testing compliance.

Hair Testing for Cocaine

Hair Testing: Pros and Cons

Hair testing is the gold standard for detecting historical cocaine use. Because cocaine is incorporated into hair as it grows, hair tests can provide a comprehensive picture of drug use over a longer period. Hair testing is often used in legal proceedings, child custody cases, and comprehensive workplace drug screening programmes.
