  • Blood Tests: Ketamine can be found in the blood for up to 24 hours.
  • Saliva Tests: Tests on saliva can find ketamine for up to 24 to 48 hours.
  • Hair Tests: These tests can find ketamine for up to 90 days, but they are not used very often to find ketamine.

  • Not Using Again: If you do not use ketamine anymore, your body will naturally get rid of it over time.
