here's what you do

if you're a farmer, you grow some cannabis plants, sporadically in your fields, mixed in with your other crops

then you wait for the governmet to drop herbicide over your crops to destroy the weed, but it also destroys your crops

then you claim compensation, but over-exagerate a tiny bit

then you pay to replant all your crops, (including the weed), and with the big wad of cash left over you buy a big sack o' weed

holy third testicle batman, that sounds fucking rad!
