Ketamine, the First Associative Anesthetic? Some Considerations on Classifying Psychedelics, Entactogens, and Dissociatives

Summary & key facts

This short paper argues that ketamine doesn't fit neatly into old drug categories. The authors suggest calling it an “associative anesthetic” because, while it is an anesthetic drug, the mental state it produces can promote new associations and overlaps with experiences caused by classic psychedelics and by drugs like MDMA. They say this idea could help researchers and clinicians think differently about how ketamine might help with mental health, but it is a conceptual proposal that needs more study.

Key facts:

• The authors propose a new label — “associative anesthetic” — to describe ketamine because it combines anesthetic effects with a mind state that can increase unusual associations and imagery.
• Ketamine’s subjective effects share some features with classic psychedelics (like psilocybin) and with entactogens (drugs such as MDMA), even though ketamine works on different brain systems than those other drugs.
• Reclassifying ketamine matters because how scientists name and group drugs affects research directions and the ways treatments are developed and used in mental health care.
• The paper is a conceptual discussion, not a report of a new experiment, so the authors emphasize that the proposed label is a way to think about ketamine rather than a proven fact.
• Ketamine is already used in medical settings and for treating depression, and this discussion is meant to clarify how its psychological effects relate to other psychoactive drugs.
