The endocannabinoidome, an expanded network of endocannabinoid-like mediators and receptors, provides targets for non-psychoactive cannabinoids like CBD and connects to the gut microbiome's role in neuropsychiatric disorders.

CBD's wide therapeutic window may come from hitting multiple eCBome targets simultaneously
What the researchers found
The endocannabinoidome extends beyond classical CB1/CB2 to include numerous lipid mediators, receptors, and enzymes involved in neuropsychiatric disorders. Non-euphoric plant cannabinoids like CBD have a wide therapeutic window because they hit multiple eCBome targets. The eCBome also connects to the microbiota-gut-brain axis, emerging as important for affective and cognitive functions.
Why it matters
This framework from a leading researcher explains why CBD may help diverse neuropsychiatric conditions and introduces the gut microbiome as a new frontier for understanding cannabinoid therapeutics.
The numbers in context
No specific effect sizes; the review provides a conceptual framework connecting the eCBome, plant cannabinoids, and the gut-brain axis.
How the study worked
Expert review by Vincenzo Di Marzo (a pioneer of endocannabinoid research) covering the eCBome concept, its role in neuropsychiatric disorders, the pharmacology of non-psychoactive cannabinoids, and the gut-brain connection.
What this study cannot tell us
Conceptual review by a single author; many proposed connections are still theoretical; the gut-brain-eCBome axis in humans remains poorly characterized.
How to read the evidence
Expert review from a field pioneer providing conceptual framework rather than new data.
When this study was published
Published in 2020.
The bigger picture
The connection between the endocannabinoidome and gut microbiome opens entirely new avenues for understanding how cannabis and cannabinoids affect mental health, potentially through mechanisms unrelated to traditional brain receptor pharmacology.
Questions still open
- Can gut microbiome interventions enhance or mimic cannabinoid effects on mental health? Which specific eCBome targets explain CBD's therapeutic effects?
Common questions
What is the endocannabinoidome?
How does the gut microbiome connect to cannabinoids?
