WHY IT MATTERS: If this bill passes in Wisconsin, patients who currently travel to neighboring states or use unregulated products could gain legal access to quality-tested cannabis under the guidance of their physicians. CLINICAL OVERVIEW: Wisconsin lawmakers have introduced a significant bipartisan bill with 47 co-sponsors to legalize marijuana, establish a regulated market, and expunge past cannabis convictions. From a clinical perspective, regulated legalization would give patients in Wisconsin legal access to tested, labeled cannabis products rather than relying on unregulated sources, while expungement provisions address the longstanding public health harms caused by criminalization.
