How to Deal With Smoke Smell

I will check out the Tenant's rights thing, thanks. Legal action, or the threat of such, may prompt them to do something, although I'd rather that be an absolute last resort.

One thing to keep in mind, at least where I live, is that tenant rights or whatever they're called amount to getting the court's permission to withhold rent until a given contractual obligation is fulfilled. I suppose it can't hurt to try, but it may not work out.
