As for campfire/bonfire smoke - First - if you have someone who knows what they're doing, there's little smoke. Second, if you pick the right woods, the smoke can be quite pleasant to breathe in fairly small quantities (assuming you can handle smoke at all). I collect and dry about 8 different types of wood for the bonfires at my church. The list includes oak, willow, cypress, camphor, mesquite, and orange. I burn most of them at different times of the year. My fires are pretty well known to be nearly smoke free, yet fragrant.

We occasionally burn tobacco in the fire too - though in small quantities and only as a reverential nod to the Indians who called Florida home before we came, or as a powerful herb associated with the season of Samhain, the Celtic feast of the Dead.
