The opening post mentioned a survey that reported that home prices could decrease by up to 29%. A more detailed report of the survey is in

"Event One is a smallish but nonetheless interesting study of real estate agents in Ontario, Canada, that suggests smoking could reduce a home's resale value by thousands of dollars. Real estate agents told pollsters commissioned by pharmaceutical manufacturer Pfizer Canada that having a regular smoker in a home can reduce its value by 20 percent, on average.
About 44 percent of the agents surveyed said smoking will reduce a home's value by some measure. Of these, one-third said the reduced value may range from 10 to 19 percent; another one-third said it could lower the value by 20 to 29 percent.
That is, of course, if the homes find buyers at all. A whopping 88 percent of the agents said that in any case, it's more difficult to sell homes where the residents are smokers.
Calculating such financial effects is a tricky thing, according to Naperville, Ill., appraiser Chip Wagner, who agreed that smells of any kind — pets, dampness, even a homeowner's profound affection for garlic — certainly could affect its sale price, though he said there's no solid formula for appraisers to follow regarding those conditions.
"Through the years, I've seen a lot of homes where people only smoke outside or in the garage," he said. "You'll walk through a home and not suspect anything, and (you) hit the garage, and it's overwhelming."
But then consider Event Two: We've become all too familiar with the concept of secondhand smoke — that's the mixture of exhaled smoke and the other ick that enters the atmosphere from the end of a lit cigarette. Health effects aside, it's a concern that has manifested itself in real estate terms, in apartment and condo buildings where residents find themselves inadvertently inhaling it via shared ventilation and heating systems and seepage through walls. Some landlords, including some of the nation's largest ones, have banned smoking because of it.
Soon, you may develop the same kind of familiarity with thirdhand smoke, which is a term that's just starting to make its way into popular usage. Thirdhand smoke is what lingers after secondhand smoke has cleared out — the noxious residue of cigarette gases and particles that settles on carpets, drapes, dust and other surfaces of a room.
Thirdhand smoke has long been suspected as a carcinogen, but at the time the Ontario real estate agents were opining that smoking could cost home sellers dearly, the scientific jury was still out.
But recently, researchers at the Lawrence Berkeley National Laboratory in California claimed that they have shown that thirdhand smoke causes significant damage to human cells. It's carcinogenic, they say, and humans can be exposed to it through inhalation, ingestion or skin contact.
"Tobacco-specific nitrosamines, some of the chemical compounds in thirdhand smoke, are among the most potent carcinogens there are," Lara Gundel, a Berkeley Lab scientist and co-author of the study, said in a statement."
