I'll play, briefly.
Can't come up with a another rationalization as to why smokers can't be allowed their own places to smoke?
Businesses, bars, clubs, etc., usually have employees. Employees have a right to a safe work environment (consistent with their duties and the job requirements - e.g. mining has different requirements from office or restaurant work).

Environmental Tobacco Smoke (ETS)
Because the organic material in tobacco doesn't burn completely, cigarette smoke contains more than 4,700 chemical compounds. Although OSHA has no regulation that addresses tobacco smoke as a whole, 29 CFR 1910.1000 Air contaminants, limits employee exposure to several of the main chemical components found in tobacco smoke. In normal situations, exposures would not exceed these permissible exposure limits (PELs), and, as a matter of prosecutorial discretion, OSHA will not apply the General Duty Clause to ETS.
Emphasis added.
OSHA has [link|http://www.osha.gov/SLTC/indoorairquality/recognition.html|lots of information] on indoor air quality standards, as does the [link|http://www.epa.gov/iaq/index.html|EPA].
Indoor cigarette smoke is a health hazard that should be minimized. It's not a discrimination issue to insist that smokers go outside to light up.
Cheers,
Scott.
