Initially when I noticed them for the 1st time a few years back I thought that might be something to do with getting high.
You might be right, but I ussually see them on the road as some one stoped and mended on the spot. Not a forensinc but seem they were dropped from a low height as they are not widely scattered(too much explanation).
I would guess if it were kids fooling around they would be a bit more secluded I guess. Also encounterd them on lanes too.
It's probably cyclists ditching them once the light CO2 is used up and the cartridge fills up with that heavy air to save those precious, precious micrograms
