How long does Ketamine stay in your system?

Ketamines gets mostly used as an aesthetic meant for both animals and humans. Apart from being used for the curative purpose, it gets also used to recreate as a ‘club drug’ with adverse effects that resemble LSD, PCP, and MDMA. The overall time that the ketamines stay in the body at a detectable level relies on the method used for testing and other personal factors. Excessive and high ketamine usage may result in physical dependence, which calls upon residential and inpatient treatment for addiction. 


Ketamine is a drug administered into the vein by either injection (intravenous) or through the muscle (intramuscular). Other varieties get administered through nasal spray for ketamines that received FDA approval in recent times for resistant-treatment, mostly for patients suffering from depression. When ketamines dosage is low, sedation and pain relief get produced; on the other hand, if the ketamines dosage is high, hallucinatory and dissociation effects get produced. The effects appear within a brief period when given IV and up to minutes when given IM.

Based on the mode in which the drug gets administered, ketamines effects can last from 5 minutes to 30 minutes. After the drug administration, ketamine is metabolized at a higher rate by the liver into less active metabolites. An estimate of 90% ketamines gets egested inform of metabolites in the urine. About 2.5 hours is the estimated time of ketamines to be reduced by half in adults and children, an estimate of around 1 to 2 hours.

Ketamines metabolism

As part of the primary body organ, the liver is the organ that processes drugs like ketamine in the body and removes them from the body. The half-life of ketamine is estimated to be one to two hours, which means that ketamines concentration in the body gets halved within that period. 

The liver metabolizes ketamines; it is first broken down into metabolites by the name norketamine. Later long norketamine is metabolized into metabolite dehydronorketamine, which gets excreted from the body through urine.

Ketamines Drug Testing and Detection Times

Ketamine detection from the human body system is through various tests that analyze saliva, blood, hair, and urine. The detection period of ketamines for every test varies because of test sensitivity and effectiveness.

Ketamine Detection Times

Drug tests for determining ketamines

Urine test

Urine test is the least invasive and the most common drug detection method. Ketamine detection standard time in urine is estimated to be around three days. Nevertheless, the research indicates that ketamines traces may be detected in urine in some instances for approximately 14 days.

Ketamines excessive use may lead to exceeded detection time that surpasses the two-day standard window. Other varying urine analysis methods, known as urinalysis, which is the process meant for drug detection in the urine, may also vary based on the time taken to detect the drug.

Saliva tests

The other mode of ketamines detection is saliva, which takes an estimate of around 24 hours from use. The ketamines detection method in saliva may vary in terms of accuracy. Home-based saliva tests that are purchased seem not to be accurate than the results that are analyses from a laboratory setting. 

Blood Tests

It is believed that ketamines can remain in the blood at some detectable levels for around twenty-four hours from the last time of its use. It gets considered a small window of detection and the cost of tests associated with blood, making the method not standard for the ketamines model of drug testing.

Hair Tests

As part of ketamine testing, a hair test involves an intensive analysis of hair follicles for any drug-related traces. It is known to have the most extended detection window. According to hair tests, ketamines usage may remain detectable up to around ninety days after the use.

Factors associated with ketamines detection time

The ketamine detection period may vary based on various known personal factors. These identifiable personal factors can affect the rate at which the body’s capacity to metabolize the ketamine drug and excrete it from the human body systems. 

The list below indicates the factors that may have impacts on the period that ketamine is detectable in the human body:


Aging, the rate at which the body is growing old, causes slowing the metabolism processes in humans. Aging can lengthen the period it takes for the human body to process the drugs fully. This means that people with old age seem to have longer detection times than young ones who have a faster metabolism process.


Ketamine amount consumed can influence the period unto which it is detectable into your system. Single-dose administration can lead to detection in the urine for a timeline of around 2-3 days. On the other hand, multiple dosage intakes can extend the detection window and increase the detection period to two weeks. Lower or higher drug dosages have the capability of influencing the detection time.

Abuse of Ketamine

The ideal standard detection times are not applicable in the excessive use of the drug and for chronic or frequent use. Long-term or systematic ketamine abuse raises the time taken for a given body to completely remove or excrete the drug from your body system.


Health is known to be the normal functioning of the body organs. Together with the vital organs, health can impact the drug metabolism. People with health-related problems, especially with kidney and liver disease, tend to experience detection times that are relatively longer. 

Ketamine Abuse affects the brain.

Ketamine has been identified as a drug that can have adverse effects on the brain, especially when administered high and low doses. Ketamine is known to cause a perception distortion which includes sight and sound since it’s a hallucinogen. This impact can lead to one feeling a sense of detachment from your body and its environs. 

Low ketamine dosage has varying effects on the brain. These effects include; impaired memory, decreased attention, a rapid ‘high,’ and reduced learning ability. In higher ketamine dosage, a person may experience a dreamlike state that leads to amnesia, deliriousness, and hallucinations.

Ketamine effects on the body

Several ketamine effects can affect body movement and also body function. Low ketamine dosage causes intoxication effects that include a decrease in heart rate and also a decreased coordination. High dosage, on the other hand, can lead to potential harm to the human body and have other associated effects, which include: high blood pressure, seizures, breathing problems, and also nausea.

When combined with other drugs, it poses an increased risk of overdose. It is not common for a given person to overdose, especially when just taking ketamine. However, ketamine perception effects pose a high death risk by drowning, crashes, vehicular, and hypothermia. 

Ketamine addiction

There has been a minimal study on ketamine potential addiction and other related drugs such as PCP and MDMA. Nevertheless, there is a study to propose that people can become tolerant to regular ketamine usage. Drug cravings may be experienced by those with ketamine tolerance gained from regular ketamine usage. These cravings match those experienced by cocaine dependence. When snorted, ketamine can lead to a rapid high,’ increasing the drug abuse risk. There have been studies of people consuming high dosages in a short time frame. This can cause adverse effects with an increased risk of fatal respiratory disease, overdose, and high blood pressure. 

Ketamine use and addiction treatment

Prolonged and excessive ketamine abuse may lead to psychological dependence. Chronic users who have already developed cravings when not consuming the drug find it challenging to do without the prescription. It makes it hard for them to quit simply because the body has adopted operating under the influence. This leads to withdrawal symptoms that can last for around 4-5 days and may include; tiredness, chills, craving for ketamine, loss of appetite, sweating, restlessness, tremors, anxiety, and depressions. In case one is used to ketamine and finds it to quit, there are known established help and support care institutions that offer professional rehab. They offer the treatments and provide a platform where one can schedule and have treatment patterns provided by addiction specialists.

Ketamine can either have long-term or short-term effects on a person’s health based on the dosage, including an adverse effect on brain functionality. For those who have developed an addiction Treatment towards ketamine, patients will undergo an inpatient detox process to withdraw from the drug safely. In the process of detox, a person may get needed to join a program of residential rehab to have drug addiction treatment. Most of the detox gets supervised medically. Ketamine addiction treatment includes specific behavioral-related therapies that are ideal and effective for patients struggling with addiction and other drug or substance abuse.
