https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3002194/ is the one I was mainly thinking of. This is about indoor solid fuel burning. They looked at coal and wood, and found very strong effects in coal (duh) but also some effects in wood. But, I didn't see any comparison to cigarettes or secondhand smoke from either of them.
It would be really surprising to me if it were the case, because secondhand smoke certainly seems like it creates more particulates in a house, since most wood smoke goes up the chimney. Plus, if you smoke, you're probably not only smoking for part of the year, like with fireplace use.
But, my intuition is not a strong argument, so that's why I'd love to see the study.
