45. Yeah, what about car exhaust?
Us tyrannical nanny staters are making cars ever cleaner and once electrics are adopted your straw man will finally die.

Cigarettes more polluting than diesel exhaust

The air pollution emitted by cigarettes is 10 times greater than diesel car exhaust, a small Italian study finds.

Researchers compared the particulate matter in the exhaust fumes from a modern car engine, fuelled with low-sulphur diesel, and in cigarette smoke. Three smouldering cigarettes produced a 10-fold increase in air particles compared to those produced by the idling vehicle.

I was very surprised. We didnt expect to find such a big difference in the particulate matter produced, says Giovanni Invernizzi from the Tobacco Control Unit of Italys National Cancer Institute in Milan, who led the study.

Ivan Vince, an air pollution expert from Ask Consultants in London, UK, says the findings are reasonable. He notes that cigarettes give off a lot more respirable particulates than the new generation of low-sulphur diesels, which help cut particulate emissions.

California's Low Emission Vehicle (LEV) program defines automotive emission standards which are stricter than the United States' national "Tier" regulations. There have been two major phases. The first began in the 1990s and ended when the Low Emission Vehicle II (LEV II) standards began to be phased in for 2004. Several states other than California now use the same restrictions. These include Maine, Massachusetts, New York, Oregon, Vermont, and Washington and are frequently referred to as "CARB states" in automotive discussions since the regulations are defined by the California Air Resources Board.

The first LEV standard created six major emission categories, each with several targets available depending on vehicle weight and cargo capacity. Vehicles with a test weight up to 14,000 pounds (6,350 kg) were covered by the regulations. The major emission categories were:

Tier I least restrictive, based on national regulations
TLEV Transitional Low Emission Vehicle
LEV Low Emission Vehicle
ULEV Ultra Low Emission Vehicle
SULEV Super Ultra Low Emission Vehicle
ZEV Zero Emission Vehicle
