I'm a fan of farmers but this mass-media notion that farmers are losing their shirts doesn't hold water in the real world. Unless they are VERY stupid, there are so many federal subsidies available, along with other programs, that farmers would never even consider growing pot. Plus, as pointed out by others, to just pick fresh plants and throw them into a garbage is not the way pot is sold (or so i've been told. Nod, nod, wink wink.) The movie itself is shallow, the characters ridiculous.
