Heh, can you imagine trying to skin a joint or smoke a bong in space?
Of all the silly ideation that has graced my mind when stoned, I can't believe I have never thought about smoking weed in space!
You'd have to make one of those smudge stick type things out of bud and wave it around. Alternately, the forced draft air-cooled weed vaporiser! With the added bonuses of less fire risk, less mess, and less gunk in the air filters to clean out afterward.
I imagine when packing a bowl you do it over the air intakes for the air con, like they do when cutting their nails. Maybe with an extra fine removable filter to collect all those little loose bits of weed on.
You know, this makes me wonder why none of the vape companies have sent a vape pen up into space as the ultimate marketing stunt. Nobody with that kind of cash to throw at publicity in that space, maybe?
Other fun party tricks in space: turn the air circulation off for a bit, form up a ball of smoke in mid air (perhaps with vortices) and then take turns swimming through it. I imagine with some clever fluids engineering you could get a stable weed-smoke trap in microgravity, and then it'll reset itself without wasting smoke. Oh the fun that could be had, if only we could get NASA to put more funding toward this critical problem : P
And we're missing the most amazing possibility. Tripping in microgravity would be absolutely mindblowing, especially looking out the window at the entire earth below you, or gazing out into the depths of space, aside from just the feeling of floating around while your brain's full of fireworks.
