Why? Because you don't like the findings?Sounds like incorrect information and bogus research.
"The study found smoke residue on surfaces and in the air of both smoking and non-smoking rooms in 30 California hotels where smoking was allowed. Levels were highest in the smoking rooms, but levels in non-smoking rooms were much higher than those found at 10 smoke-free hotels."
Is this really surprising? If you allow smoking within a structure, smoke will migrate to other rooms.
