“Smoking Ban”
• “Smoking Ban” is not an adequate description
More descriptive….
• “Comprehensive Smoke Free” legislation
• “Smoke Free” Policy
Smoke Free Legislation
• Typically, legislation that eliminates smoking in public places
• The smoker is NOT the medical focus of this type of legislation
(not protecting the smoker from themselves)
• Focus in on reducing injury inflicted on others
