“…Air nicotine levels in smoking rooms were significantly higher than in non-smoking rooms; (but) they were also 40% higher in non-smoking rooms of hotels operating partial smoking bans than in those operating total bans…findings demonstrate that some non-smoking guest rooms in smoking hotels are as polluted with [third hand smoke] as are some smoking rooms…”
Non-smoking rooms in hotels operating a partial smoking ban don’t protect their occupants from tobacco smoke, reveals new research published online in Tobacco Control. The researchers analyzed the surfaces and air quality of rooms for evidence of tobacco smoke pollution (nicotine and 3EP), known as third hand smoke, in a random sample of budget to mid-range hotels in San Diego, California.
Ten hotels in the sample operated complete bans and 30 operated partial smoking bans, providing designated non-smoking rooms.
Non-smokers who spent the night at any of the hotels, provided urine and finger wipe samples to assess their exposure to nicotine and a cancer causing agent found specifically in tobacco smoke—known as NNK—as measured by their metabolites cotinine and NNAL.
The findings showed that smoking in hotels left a legacy of tobacco pollution in both smoking and non-smoking rooms. A partial smoking ban did not protect the occupants of non-smoking rooms from exposure to tobacco pollution.
