The Maryland Occupational Safety and Health (MOSH) advisory board recently proposed a smoking ban in most Maryland workplaces, including bars and restaurants, unless smoking is restricted to a separately ventilated area where nonsmoking workers cannot be required to enter. Results from the 1992-1993 Current Population Survey strongly suggest that there is broad support among Maryland residents for such restrictions and that the MOSH rules would merely extend an already widespread practice in the state. Efforts by the tobacco industry to gain an injunction against the proposed MOSH regulations would not appear to be supported by a clear majority of Maryland residents.
