How Long Does Ketamine Stay in Your System?

Ketamine is a potent dissociative anesthetic that was originally intended for medical use in animals and humans. The Schedule III controlled substance is commonly abused for its hallucinogenic effects.

This guide addresses one important issue: how long does ketamine stay in your system?

Ketamine Half-Life

For those wondering, “What is the half-life of ketamine”, the ketamine elimination half life is around 3 hours. After this time, blood concentration levels of the drug will reduce by half. A substance is entirely eliminated from the system after five half-lives – up to 15 hours in the case of ketamine.

Despite its relatively short half-life, ketamine can be detectable in the body for an extended duration through various testing methods:

  • Saliva test: Ketamine can be identified in saliva for approximately 24 hours after consumption.
  • Blood test: Ketamine can be traced in the bloodstream for up to 3 days after ingestion, with optimal detection occurring within the first 24 hours.
  • Urine test: Ketamine remains detectable in urine for about 14 days, although some studies suggest detection may extend up to 30 days after the last use.
  • Hair test: Residues of ketamine can linger in the hair and hair follicles for as long as 4 months following a single instance of use.

Several factors can influence the duration of time ketamine remains detectable in your system:

  • Age and general health: Younger, healthier individuals tend to eliminate ketamine more rapidly due to their faster metabolisms.
  • Hydration levels: Ketamine primarily exits the body through urine. Therefore, individuals who maintain proper hydration and consequently urinate more frequently tend to eliminate ketamine more swiftly.
  • Metabolic rate: Individuals with a faster metabolic rate can break down and eliminate ketamine more efficiently than those with slower metabolisms.
  • Kidney and liver function: Efficient kidney and liver function are crucial for eliminating ketamine from the body. Impaired functioning of these organs can lead to a prolonged elimination process.
  • Body mass: Individuals with higher body mass can potentially metabolize ketamine more rapidly, as the amount of ketamine taken represents a smaller proportion of their overall body mass.
  • Dosage: Higher doses of ketamine can extend the time required for the body to eliminate the drug, as the system must work harder to process and expel it.
  • Frequency of use: Regular ketamine use can result in overlapping doses, causing the substance to accumulate in the body and prolonging the elimination process.
  • Concurrent drug use: Mixing ketamine with other substances can complicate the body’s detoxification process, as it must concurrently break down multiple substances, delaying the elimination of ketamine.

Symptoms of Ketamine Withdrawal

If you or a loved one are struggling with ketamine addiction and trying to get sober, ketamine withdrawal can occur. While ketamine withdrawal can be different for everyone, there are common symptoms to look out for to determine if withdrawal is occurring.

The signs of ketamine leaving your system can include:

  • Cravings
  • Depression
  • Anxiety
  • Insomnia
  • Fatigue
  • Difficulty Concentrating
  • Mood Swings
  • Sweating/Chills
  • Nausea/Vomiting
  • Muscle Cramps
  • Body Aches

The severity of these symptoms can vary from person to person, depending on factors like length of use, amount being taken, and existing health status. If you or a loved one have decided to quit ketamine, seeking a treatment center that specializes in ketamine detox can provide the safest and most successful recovery.
