And before you begin the long boring lecture about the health expenses to the public by tobacco related illnesses, guess what?
Providing health care isn't the proper sphere of government.
Here's another thing:
Dictating automotive fuel efficiencies isn't the proper role of government, either. The government is currently in the business of collecting taxes from the gasoline prices it's helped to inflate by arbitrarily and unreasonably denying drilling permits to domestic oil companies, and propagandizing the "need" for it to control fuel efficiencies by legislative fiat because the price of fuel is being driven by despot laden oil from overseas, even though the United States has the largest known reserves of oil on the planet.
Drilling domestically is going to be what keeps Obama out of office in 2013.
