Seems that if you are worried that you might somehow get in trouble for carrying these around than dont carry them, how simple is that?
Most of the sketchballs around this forum could get arrested for carrying just the balloon anyway.
Kind of missing the point.
The alternative being leaving it on the ground for someone else to have to deal with it, which seems somehow wrong. I understand the wisdom of leaving a pipe or a container of drugs for someone who might appreciate them to find, but the canisters (and now the balloons) are Just Garbage in my mind. Kinda like toilet paper or feathers.
My impulse is to pick it up and pack it out.
Ignorance having been bliss this time around, I did just that.
It just seems a shame to have to think twice about it next time, and to leave it there for someone else to pick up. Is there not a "hazardous moop" dropoff spot for such things?
