Studies by condition
Conditions with a Dr. Weedy guide link to it. The rest have studies behind them but no guide from us yet.
Other topics researchers study
Not conditions, but often the subject of cannabis research: how people use it, the plant itself, how it acts in the body.
How strong is the evidence?
For doctors and careful readers: what kind of studies stand behind the numbers above, for the filters you chose.
Study design
Stronger designs at the top. Reviews pool earlier studies; trials test cannabis against a control.
92,491 studies are not classified yet: our pipeline has not read them.

About this library
The library collects published research on cannabis and cannabinoids from OpenAlex, PubMed and Semantic Scholar. A paper found in several databases is counted once. The library is updated every night. Retracted papers are left out.
Body areas and conditions are matched from each paper's title, keywords and medical subject headings, and from our AI reading of the full paper where we have it. One study can touch several organs. This page summarises research. It is not medical advice: talk to a doctor before using cannabis for a health condition.
