Summary

This study tests whether a digital web application can help regular cannabis users adopt protective strategies to lower cannabis-related risks. About 565 adults in Lausanne, Switzerland, who already take part in a cannabis sales regulation pilot, will use the app freely and complete surveys every six months. Researchers compare different app modules to see which ones work best for harm reduction.
