Ketamine is a dissociative anesthetic used by health professionals in controlled medical settings. Nonmedical use can alter perception and awareness of the body and surroundings.
Health effects and risks
Effects may include confusion, impaired coordination, memory problems, and increased blood pressure. Because awareness and judgment can be impaired, accidents and other injuries are possible. Mixing ketamine with alcohol, opioids, or sedatives can increase danger. Seek emergency care for loss of consciousness or breathing problems.
Testing and next steps
Drug screens vary by specimen and by the substances listed on a test’s panel. Check the instructions and panel before selecting a test; do not assume every product detects this substance. A home screen is preliminary. For more on specimen types, read Drug Testing Methods; for a preliminary positive result, read Unexpected or Preliminary Positive Results. The Substance Information hub lists the current staging test options.
