How Long Does Ketamine Stay In Your System? Let’s Find Out.

Table of Contents

Ketamine, a powerful anesthetic, and dissociative drug, has gained prominence in medical and recreational circles alike. As its usage diversifies, questions surrounding its duration in the human system have become increasingly pertinent. 

This comprehensive guide delves into how long Ketamine lasts in the body, shedding light on factors that influence its duration and providing valuable insights.

Timelines: How Long Does Ketamine Stay In Your System?

How Long Does Ketamine Last

Short-Term Effects:

The immediate effects of Ketamine, often referred to as the “trip,” typically last for a duration of 45 to 90 minutes. During this period, users may experience altered perceptions, hallucinations, and a dissociative state. It’s crucial to note that the intensity of these effects can vary based on factors mentioned earlier.

Long-Term Considerations:

In chronic users or individuals with a history of prolonged ketamine use, the drug’s metabolites may persist in the body for an extended duration. Studies suggest that traces of Ketamine and norketamine may be detectable in biological samples for up to two weeks after the last use.

Detection in Biological Samples

Let’s explore how long Ketamine stays in your body, examining detection timelines across various biological samples—saliva, blood, urine, and even hair:


Saliva testing offers insights into recent ketamine use. After ingestion, Ketamine and its metabolites can be detected in saliva for a relatively short period, typically ranging from one to two days. This method is particularly effective for identifying recent exposure, making it a valuable tool in specific testing scenarios.


Blood tests provide a real-time snapshot of ketamine presence. Following administration, Ketamine rapidly enters the bloodstream, allowing for immediate detection. However, the detection window is relatively brief, usually spanning a few hours to a day. Blood tests are often employed in emergencies or scenarios requiring precise, immediate results.


Urine testing is the most common method for detecting Ketamine and its metabolites. This method offers a broader detection window, extending from one to four days after use. The variability in detection time is influenced by factors such as individual metabolism, frequency of use, and dosage. Urine tests are widely utilized in employment screenings and rehabilitation programs.


Hair testing provides a unique perspective on long-term ketamine use. Unlike other biological samples, hair can retain traces of Ketamine and its metabolites for an extended period. Detection in hair typically covers up to 90 days, offering a historical record of substance exposure. This method is valuable for assessing prolonged or chronic ketamine use.

What Factors Affect How Long Does Ketamine Stay in Your System?

It’s crucial to delve into the various factors influencing its duration. Ketamine, a powerful anesthetic, and psychedelic drug, undergoes complex processes within the human body, and its stay can vary from person to person.

Here are some factors that affect How Long Does Ketamine Stay In Your System in the human body:

Metabolic Rate and Ketamine:

The metabolic rate of an individual plays a pivotal role in determining how long Ketamine lingers in their system. Individuals with a high metabolism tend to process and eliminate Ketamine more rapidly than those with a slower metabolic rate. Metabolism directly impacts the breakdown of Ketamine in the liver, influencing the duration of its presence in the body.

Liver Function:

A healthy liver is essential for efficient drug metabolism. The liver’s enzymatic activity is responsible for breaking down Ketamine into metabolites that can be excreted. If someone has liver conditions or impaired liver function, the process may be slowed down, leading to an extended duration of Ketamine presence in the system.

Impact of Ketamine Dosage:

The dosage of Ketamine administered significantly affects its duration in the body. Higher doses take longer to metabolize and eliminate. Individuals using Ketamine for medical purposes or recreational use should be aware that a more significant initial amount may extend the drug’s presence in their system.

Frequency of Ketamine Use:

Frequent use of Ketamine can result in its accumulation in the body over time. Chronic users may experience a prolonged presence of Ketamine metabolites, even with lower doses. Understanding the impact of usage frequency is vital for those seeking to manage the duration of Ketamine in their system.

Body Mass and Composition:

Body mass and composition are crucial determinants of how long Ketamine stays in the system. Individuals with higher body fat may retain Ketamine for a more extended period as the drug is lipophilic, meaning it has an affinity for fat tissues. Lean individuals may experience a faster elimination rate.

Age and Health Status:

Age and overall health contribute to the body’s ability to process and eliminate substances. Younger individuals, generally possessing more robust metabolic systems, may clear Ketamine more efficiently than older individuals. Additionally, overall health status influences the efficiency of the organs responsible for Ketamine metabolism.

Importance of Hydration:

Staying well-hydrated is crucial for expediting the elimination of Ketamine from the body. Adequate hydration supports kidney function, enhancing the excretion of Ketamine and its metabolites through urine. Dehydration, however, can lead to a slower elimination process.

Urinary pH Levels:

The pH levels of urine can impact the elimination of Ketamine. Alkaline urine facilitates the excretion of Ketamine and its metabolites more effectively than acidic urine. Monitoring and maintaining optimal urinary pH levels can influence the duration of Ketamine in the system.
