The Tribunal de Justiça de Rondônia (TJ-RO) has ruled that the state law number 5.557/2023, which allows for the free provision of cannabidiol medications via the Sistema Único de Saúde (SUS), is constitutional. This decision came after the Rondônia government filed a Direct Action of Unconstitutionality (ADI) against the law, claiming that the state assembly could not impose obligations on the executive branch, particularly the State Secretary of Health. The government argued that only the governor has the authority to propose such legislation.

Despite these claims, the majority of the judges did not side with the government's argument and adopted the opinion of the rapporteur, Flávio Henrique de Melo. The court stated that the Brazilian Constitution permits shared responsibilities among the Union, states, and the Federal District in health matters. The rapporteur emphasized that the ruling aligns with existing national health policies supporting the use of cannabidiol for medical purposes.

This ruling is significant as it paves the way for increased access to medical cannabis products, which could provide relief for patients with various health conditions. It reflects a growing acceptance and integration of cannabis-related treatments within Brazil's public health framework, enhancing patients' rights and potentially leading to broader discussions on drug policy reform in the country.
