The anti-smoking brigade relies on proving that second hand smoke is dangerous. Even the the tobacco industry has not denied that. Further, while there is no evidence that occasional low-level exposure to cigarette smoke poses a cancer hazard, there is a clear biological hypothesis on how ETS might cause cancer at sufficiently high dose exposure. Those who reject the ETS-disease link consistently and exclusively cite the Environmental Protection Agency as the source of claim that ETS causes health effects on nonsmokers. But the suggestion that environmental tobacco smoke is not a human carcinogen can be dismissed as devoid of scientific basis.
Smokers already pay more than their share.
It is unfair to require the Industry to reimburse medical costs. Some argue here that the contribution of the Industry to our economy offsets the costs of cigarette related disease. Cigarette companies should not be held legally responsible for the health consequences of smoking. Our society is already too litigous. However, they don't acknowledge that government-assigned immunity from lawsuits already keeps the tobacco companies in business.
