A gas mask was actually another option I had considered. Dual use may include a canister that attaches to the end, for when you absolutely must use something with harmful vapors.
I made one once about 35 years ago that included a small pump, hose, copper tubing with a hole in the top and the end open, with my finger over the end, kind of like the bong principle except with a joint, which goes in the top hole.
It would suck down a dube in about 15 seconds! The only problem was the resin, which would gum up the pump.
