Ketamine, also known as 'Ket', is a powerful hallucinogenic drug that can be snorted, swallowed, or injected. It is often misused as a recreational or party drug, and its effects can last anywhere from 30 minutes to an hour. But how long does it stay in your system?
Ketamine has a half-life of around 2.5 to 45 minutes in adults, which means it takes around 2 to 3 hours for the amount of Ketamine in your body to be reduced by half. While this may seem like a short amount of time, Ketamine can be detected in the body much longer through various drug tests.
A blood test, for example, can typically detect Ketamine for up to 3 days after consumption, but it is most effective within the first 24 hours. This test is usually accompanied by a urine test, which can detect the drug for up to 14 days, or even 30 days in some cases.
Other tests include saliva tests, which are effective for up to 24 to 48 hours, and hair tests, which can detect Ketamine usage for months after consumption.

What You'll Learn
Ketamine can be detected in blood tests for up to 3 days
Ketamine, also known as 'Ket', 'Special K' or 'K', is a powerful hallucinogenic drug. It is medically used as an anaesthetic but is also used recreationally for its dissociative effects. It is typically snorted or swallowed, but it can also be injected.
The half-life of ketamine is around 2.5 to 45 minutes in adults. This means that it takes the body around 2.5 to 3 hours for the ketamine concentration in the blood to reduce by half. However, ketamine can be detected in blood tests for much longer than its half-life.
Blood tests are typically able to detect ketamine for up to 3 days after consumption, although the test is most effective within the first 24 hours. This means that even after the effects of ketamine have worn off, it can still be detected in the body.
The detection time can vary depending on several factors, including age, body weight, frequency of use, hydration levels, and liver and kidney health. For example, younger people with faster metabolisms may clear ketamine from their system more quickly, and it is also eliminated faster in those who are well-hydrated.
It is important to note that ketamine is not typically included in standard drug tests. However, specialised tests can be ordered by doctors or employers if there is a suspicion of drug use. These tests are widely available and can provide valuable information about ketamine usage.

Blood tests are most effective within the first 24 hours
Ketamine, also known as 'Ket', is a powerful hallucinogenic drug. It is often snorted or swallowed as a tablet, but it can also be injected. The effects of ketamine include a trance-like state, sedation, warped perceptions of space and time, and hallucinations.
When it comes to detecting ketamine in the body, blood tests are considered one of the most accurate methods. Blood tests can usually detect ketamine in the system for up to 3 days after consumption, but they are most effective within the first 24 hours. This means that if a blood test is conducted within 24 hours of ketamine use, there is a higher likelihood of detecting the drug in the bloodstream.
The effectiveness of a blood test within the first 24 hours is due to the way ketamine is metabolized and excreted by the body. Ketamine has a half-life of around 2.5 to 45 minutes in adults, which means it takes about 2.5 to 3 hours for the amount of ketamine in the body to reduce by half. After this point, the concentration of ketamine in the blood starts to decrease, and it takes about 10 hours for the substance to pass out of the body completely.
However, even though ketamine may be eliminated from the body within 10 hours, it can still be detected in blood tests for a longer period. This is because blood tests are sensitive enough to detect trace amounts of the drug, which can remain in the system for a few days after use. Therefore, if someone has taken ketamine, it is possible for it to be detected in a blood test conducted within the first 24 hours, increasing the likelihood of a positive result.
In addition to blood tests, ketamine can also be detected through other means, such as urine, hair, saliva, and fingernail tests. Each of these methods has different detection windows, with urine tests detecting ketamine for up to 2 weeks, hair tests for up to 4 months, saliva tests for up to 48 hours, and fingernail tests for up to 12 months.
It is important to note that various factors can influence how long ketamine stays in the body and how long it is detectable in tests. These factors include age, overall health, metabolism, the amount consumed, hydration levels, liver and kidney function, body mass, frequency of use, and whether ketamine was mixed with other drugs.

Ketamine is not part of a standard drug test
Ketamine, also known as 'Ket', 'Special K' or 'K', is a powerful hallucinogenic drug. It is often misused as a recreational or party drug, and its use has been rising in recent years.
However, this does not mean that ketamine use cannot be detected. While blood tests for ketamine are uncommon, it can be detected in the blood for up to 3 days, with the test being most effective within the first 24 hours. It takes about 2.5 hours for ketamine to move from the bloodstream into the body's tissues.
If ketamine abuse is suspected, a separate, specialised test can be ordered to detect its presence. These tests are widely available and can be requested by doctors or employers.
In addition to blood tests, ketamine can also be detected through other means. For example, it can be found in urine for up to 14 days, and possibly up to 30 days, after the last use. It can also be detected in hair for up to 4 months after a single usage. Saliva tests can detect ketamine for up to 24-48 hours after consumption.
The time it takes for ketamine to be eliminated from the body varies from person to person. Factors such as age, body mass, metabolism, liver and kidney function, and hydration levels can influence how long ketamine stays in the system.

Doctors or employers can order specialty tests for ketamine
Ketamine, also known as 'Ket', 'Special K' or 'K', is a powerful hallucinogenic drug. It is not typically included in standard 5-panel or 10-panel drug screenings. However, doctors or employers can order specialty tests for ketamine if they suspect an individual is under the influence of the drug. These tests are widely available and can check for the presence of ketamine in the system.
Ketamine is a drug that is often abused and has been implicated in sexual assaults. It is not part of a standard drug test, but it can be detected in the body for some time after use. The half-life of ketamine is around 45 minutes, and it usually takes five half-lives for a drug to be eliminated from the body. This means that, on average, it takes around three hours and 45 minutes for a healthy adult to eliminate ketamine from their system. However, this can vary depending on individual factors such as age, body mass, genetics, liver function, and overall health.
The time it takes for ketamine to be eliminated from the body also depends on the type of test being used. In a urine test, ketamine can be detected for up to 14 days after the last use, and some studies have recorded detection times of up to 30 days. In a hair test, ketamine can be detected for up to 90 days after the drug was taken. In a saliva test, ketamine can be detected for up to 24 to 48 hours after the last use.
Blood tests for ketamine are uncommon, but it takes the drug about 2.5 hours to move from the bloodstream into the tissues of the body. This likely reflects the time it can be found in the blood, and it has been suggested that it can be detected for up to three days after use, although it is most effective within the first 24 hours.

Ketamine is usually gone from the body after around 10 hours
Ketamine, also known as 'Ket', 'Special K' or 'K', is a powerful hallucinogenic drug. It is a dissociative anaesthetic, meaning that it does not knock patients out, but instead renders them 'detached' from their pain. It is usually snorted or swallowed as a tablet, but it can also be injected in liquid form.
The half-life of ketamine is around 2.5 to 45 minutes, which means it takes 4-5 times that amount – around 10 hours – for the substance to pass out of the body completely. This is the time it takes for the ketamine in your body to reduce by half. When the amount of ketamine in your system reduces, you may start having a 'comedown'.
While 10 hours may seem like a short amount of time, ketamine can be detected in your body using a number of tests for much longer.
Blood Test
A blood test can show ketamine in your system for up to 3 days after you've taken it, but it's most effective within the first 24 hours. This is because it takes ketamine about 2.5 hours to move from the bloodstream into the tissues of the body.
Urine Test
Urine tests can detect ketamine for much longer – up to 14 days after the last use, and some studies suggest that it's possible for ketamine to be detected in urine for as long as 30 days after it was taken. This is because most ketamine leaves the body in urine, so the more hydrated you are, the quicker it will leave your system.
Hair Test
Hair tests can show traces of ketamine for up to 4 months after a single use. It takes about two weeks for ketamine to show up in hair follicles, and a further 10 days to start growing above the scalp.
Saliva Test
Saliva tests can detect ketamine for up to 24-48 hours after it was last taken.
Fingernail Test
Fingernail tests can confirm if ketamine has been taken within the last year.
It's important to note that these detection periods are estimates and can vary from person to person, depending on factors such as age, body weight, frequency of use, hydration levels, purity of ketamine, general health status, and the route of administration.

Frequently asked questions
A blood test can detect ketamine for up to 3 days after consumption, but it is most effective within the first 24 hours.
The half-life of ketamine is around 2.5 to 3 hours in adults, meaning it takes around 10 hours for the substance to pass out of the body completely.
The half-life of a drug refers to the time it takes for the concentration of the drug in the body to reduce by half. Detection time refers to how long the drug can be detected in the body through tests.
Ketamine is metabolised by the liver into norketamine and dehydronorketamine, which are then excreted in the urine or through the breath.
Factors such as age, body weight, frequency of use, hydration levels, liver and kidney function, and the amount and purity of ketamine consumed can influence how long it stays in the body.
