Yes
A brief comment on the extent of sub-national legislation:
Several states and cities have issued their own smoke-free laws. States which have released their own smoke free laws in accordance with the FCTC include: Amazonas (population: 4.2 million inhabitants), Paraíba (4 million inhabitants), Paraná (11.5 million inhabitants), Rio de Janeiro (17.4 million inhabitants), Rondonia (1.8 million inhabitants), Roraima (630,000 inhabitants), and São Paulo (46.3 million million inhabitants). All mentioned laws do not have exceptions for smoking areas in indoor places.
The smoke-free laws of the states of São Paulo, Paraná, and Rio de Janeiro were the subject of constitutional challenges. In each case, the court upheld the state law.
