It's ridiculous. I could, technically, grow my own tobacco plants. I can grow my own hops, or grapes, or potatoes. I should be able to grow my own cannabis. Treat it like all the other drugs we're encouraged to buy!
If I can brew beer and ferment wine in my basement for my own use, then there is no logical reason I shouldn't be able to grow a handful of pot plants in my back yard.
Fucking prudes.
