I am watching this with great interest, as we have problems in our condo where second hand smoke seeps from neighbouring units and it can be nearly intolerable. It comes in through the AC/heat ventilation, from holes in walls around pipes and wiring, etc. I've spray-foamed every crack in our place. We've gone through two air purifiers (they help a bit but not much, and lose effectiveness after 6 months or so) and complained to the condo board, who sympathize but say their hands are tied. There's not much else I can do. Even when I open the window during nice weather the nearby smoking unit apparently does the same, because smoke drifts in through the window, too.
The smell is strong. It burns my eyes. My wife has serious allergies to almost everything under the sun including dust, and the smoke aggravates them. We spend $300 several times a year for allergy shots. We removed all broadloom, we sealed our mattress in an expensive anti-mite/allergen cover, we don't don't have a cat even though we both would like to, all because of her allergies. Now these sacrifices are being undone by a selfish neighbour.
This is our HOME. We work hard to pay a mortgage, and we have invested tens of thousands of dollars in renovations into it. But in the blink of an eye a single neighbour can move in nearby and degrade our quality of life drastically. Walking down the hall, I know that there are precisely two smokers on out entire floor of about 24 units. How do I know? The smell outside the doors. A non-smoker can pick that up easily.
How many other units do these few smokers infiltrate with the smell? Why should the rights of a tiny minority of residents overpower those of the vast majority of non-smoking units? Why is it up to me to try to spend time and money trying to seal my unit, rather than the responsibility of smokers to seal theirs? Why am I protected by law from cigarette smoke when I'm in a public place or at work, but not in my own home?
The same old tired arguments of smokers with their "totalitarianism" and "rights" complaints infuriate me. This is not a minor inconvenience, like the odours of a neighbour cooking, which are short-term and harmless. Smoking is a known carcinogen, and exposures to small amounts over long periods of time is shown to cause cancer. All I ask is to be healthy and comfortable in my own home. Now, I'm pretty sure that is my right.
