My current research has revealed that smoking was common through a significant chunk of pre-history.
It was first done by dragonfly-like insects in the early Palaeozoic era as a form of extreme cannibalism. As far as I can make out from the limited texts available, the central tenet of their belief system held that inhaling the 'soul smoke' of rival clans caused 'great joy and upliftment to the skies.' Gradually, the practice came to be seen as barbarous and was sold off to the now extinct Malanga fly who developed it to a fine art, using beautifully crafted obsidian pipes in convoluted rituals. They concentrated wholly on smoking members of new species with particularly desirable character traits in the belief that they would aquire more legs or a liking for sprouts, or whatever.
They seem to have had some measure of success: the dominant theory about the eventual fate of the Malanga (one I made up all by myself) is that they evolved into 'mind bees' that live in your head and become terribly agitated the morning after you have a night on the tiles, when they cause tinnitus.
