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.

About this library
The library collects published research on cannabis and cannabinoids from Semantic Scholar, OpenAlex and PubMed. A paper found in several databases is counted once. The library is updated every night. Retracted papers are left out.
One study can touch several organs and conditions. This page summarises research. It is not medical advice: talk to a doctor before using cannabis for a health condition.
