By making marijuana illegal, the agricultural people can't grab hold of it like they did with corn and wheat. So those companies are scrambling around trying to get hold of it, but they can't, because it's a cottage industry, and it will always be a cottage industry. Because the minute the big companies try to make it their own, like they did with soybeans...like Monsanto, they put their own patent on seeds, and you can't do that with marijuana.
