Summary

This trial tests whether allowing adults in Basel to buy cannabis from pharmacies, instead of the illegal market, changes how much they use and their mental and physical health. About 374 adults who use cannabis at least monthly will be randomly assigned to either regulated pharmacy access or the illegal market. Researchers will track changes in problematic use, depression, anxiety, and psychosis over time.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Regulated cannabis access in pharmacies
What this could lead to
If it works, this could point toward a safer way for adults to obtain cannabis, potentially reducing problematic use and improving mental and physical health.
What could go wrong
This is a single-city study, and results may not apply elsewhere. The trial does not test the health effects of cannabis itself, and outcomes depend on how participants respond to regulated access.
