Here's what would be nice:
A continually updated overview of how much of any given drug counts as "personal use" in different countries. Either on here or as an off-board resource.
Say, for example for LSD, "[Country A] - 500ug," "[Country B] - 250 ug," and so on, A-Z, all the way down. And ditto for, well, pretty much every other drug there is.
I shall help and put Israel's amounts.
