Clean Indoor Air Act


  • The Maryland Clean Indoor Air Act (CIAA) of 2007 prohibits smoking in virtually all indoor workplaces in order to “preserve and improve the health, comfort, and environment of the people of Maryland by limiting exposure to environmental tobacco smoke.”
  • The law provides for fair and consistent statewide protection from exposure to secondhand smoke in indoor settings.
  • People in Maryland will now have clean, smoke-free air while working, dining, shopping, or relaxing throughout the state.
  • The CIAA went into effect February 1, 2008.
