As far as I can find no there are none dealing with the combustion of it. A bunch dealing with it in water supplies and it's been found to be non toxic. I also found papers saying they found it on stored tobacco leaves. Isolation of Bacillus thuringiensis from Stored Tobacco and Lasioderma serricorne (F.)
& Occurrence of Bacillus thuringiensis on cured tobacco leaves.
If it's on tobacco leaves, somebody has been smoking it at some point. You are right that not enough research has been done on the combustion of pesticides, I figure tobacco is the closest mainstream thing that people do smoke. If it's considered non-toxic on tobacco, I would assume it's non toxic on weed, but realistically it needs it's own research done. Which costs money. Which isn't coming on a federal level, only from private funding. So yeah. It might be a while still.
