“While there is still some debate around the potential increase in drunk driving, there is a vast, peer-reviewed, scientific literature around the harms of secondhand smoke inhalation, and around the massive health benefits associated with the sharp decline in smoking in part due to smoke-free policies.
We know that smoking bans have been effective at reducing secondhand smoke exposure. Bans in restaurants, bars, and other hospitality establishments have the added benefit of ensuring that workers are not forced to carry the health costs against their will simply due to their place of employment. Bans have also been effective at reducing smoking and “reducing opportunities to smoke, changing smoking norms, and reducing smoking rates.”
Smoking and exposure to secondhand smoke increases the risk of cardiovascular disease, pulmonary disease, cancer, and death. Research has shown that heart attack admissions “rapidly declined” after the implementation of 100 percent smoke-free laws.
All of this to say that if there was in fact a small increase in fatal drunk driving accidents as a result of these bans, the bans were still worth it.”
