A comprehensive literature review cataloged CBD interactions with endocannabinoid receptors, ion channels, cytochrome P450 enzymes, inflammatory pathways, and sex hormones, spanning effects on seizures, pain, nausea, neurodegeneration, and drug metabolism.

What the researchers found
CBD interacts with endocannabinoid receptors, multiple ion channels, cytochrome P450 enzymes (affecting drug metabolism), inflammatory pathways, and sex hormone regulation. Documented effects span psychiatric disorders, seizures, nausea/vomiting, pain, thermal regulation, neuronal signaling, neurodegenerative diseases, reproductive aging, and energy homeostasis.
Why it matters
As CBD consumption increases rapidly worldwide, understanding its full range of biological interactions is essential for clinical management — especially given the potential for CBD to interact with pharmaceutical medications through cytochrome P450 enzymes.
The numbers in context
Interactions documented with: endocannabinoid receptors (CB1, CB2), multiple ion channels, CYP450 enzymes (drug metabolism), inflammatory pathways, sex hormones. Effects on: seizures, pain, nausea, neurodegeneration, psychiatric disorders, thermal regulation, energy homeostasis.
How the study worked
Comprehensive literature review across PubMed, Web of Science, and Google Scholar. Included cell culture, animal model, biochemical, and clinical studies. Findings synthesized thematically by body system.
What this study cannot tell us
Narrative review rather than systematic review with defined search criteria. Cannot assess quality of underlying evidence systematically. Many included findings are from preclinical studies. Rapidly evolving field means some interactions may be incompletely characterized.
How to read the evidence
Comprehensive narrative review useful as reference, but not systematic and includes heterogeneous evidence quality.
When this study was published
2025 publication.
The bigger picture
CBD is increasingly used alongside pharmaceutical medications, yet many clinicians remain unaware of the full scope of CBD interactions. This review serves as a reference for the breadth of biological targets CBD affects.
Questions still open
- Which CBD-drug interactions are most clinically significant?
- At what doses do CBD interactions with CYP450 enzymes become relevant?
Common questions
What does CBD do in the body?
Can CBD interact with other medications?
