However, today our focus on not on negative health effects on the smoker…..

Secondhand Smoke(Passive Smoking)

• Negative effects of smoke on people who aren’t doing the smoking

• No longer speculation that this is dangerous for those exposed to secondhand smoke

Secondhand Smoke DeathsUnited States• Lung cancer – 3,000 deaths annually • Heart Disease – 35,000 deaths annually

North Dakota• 80-140 deaths annually

Second Hand Smoke and Cardiovascular Risk (Heart Attack)• Cardiovascular Risk (Heart Attack) is

~80-90% of primary smoking

• Secondhand smoke increases risk of heart attack by 30%

• Well understood phenomenon- no longer speculative concerning harmful effects

“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
