What was done

The authors conducted a narrative review of the origin, historical usage, and recent literature surrounding the terms "empathogen" and "entactogen" for MDMA and related compounds. They examined the psychological profiles associated with each term, compared these to classic psychedelics, and proposed a unified conceptual framework and nomenclature.

What was found

The abstract reports no numerical data. The review notes that published studies rarely articulate specific justifications for selecting either "entactogen" or "empathogen." The authors argue that both reflect an overarching theme of intense connection, proposing the term "connectogen" to encompass intrapersonal connection (entactogenic effects), interpersonal connection (empathogenic effects), and emerging broader connective domains such as connection to the body, the present moment, the world, and spiritual principles.

Why it matters

It offers a unified theoretical taxonomy ("connectogen") to reconcile a long-standing terminological divide in psychedelic psychopharmacology and provide a clearer framework for categorizing MDMA's psychological effects.

Limits

This is a non-systematic conceptual and narrative paper that presents no new experimental or clinical trial data. No quantitative outcomes, search methodologies, or formal evidence syntheses are provided in the abstract.
