How Long Will Ketamine Last in Your System?

Drugs differ in the amount of time that they stay present in the body. Some substances can last in the body for a relatively short while, whereas others can stick around for longer.

How Long Ketamine Stays In Your System

The approximate amount of time that ketamine will still be detectable in urine after use is 3-5 days.

However, the substance can be detectable in urine tests for up to 14 days and in hair follicle tests for up to 90 days.

While a urine test and hair follicle test could potentially detect ketamine in the body 14 days and three months after use, respectively, these will just be trace amounts of the drug.

It’s important to note that after taking ketamine, your liver will quickly metabolize the substance into less active metabolites (e.g. norketamine). 

Different Factors Affect The Detectability Of Ketamine

The huge variation in the detectability of ketamine comes down to many different factors. Let’s explore each of these in turn.

Individual Drug Metabolism

Drug metabolism rates vary between individuals. Some people metabolize a drug quickly, whereas, for others, the process can be much slower. 

Ketamine Dosage

Dosage is another crucial factor that can alter how long ketamine lasts in the body’s system. When taking a small dose of ketamine, it will stay in your body for a much shorter amount of time.
