question:
In the United States, Congress has not attempted to enact any nationwide federal smoking ban. Therefore, smoking bans in the United States are entirely a product of state and local criminal and occupational safety and health laws. As a result, the existence and aggressiveness of smoking bans varies widely throughout the United States, ranging from total bans (even outdoors), to no regulation of smoking at all. Jurisdictions in the greater South tend to have the least restrictive smoking bans or no statewide bans at all. Of the 60 most populated cities in the United States, all but 17 ban smoking in all bars and restaurants.

question:
Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Some governments have made efforts since the 1970s to reduce the release of sulfur dioxide and nitrogen oxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes, and sulfur dioxide is produced by volcanic eruptions. Acid rain has been shown to have adverse impacts on forests, freshwaters and soils, killing insect and aquatic life-forms, causing paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues as well as having impacts on human health.
answer:

what is acid rain and what are its effects
