It seems to me, that if it becomes legal in California, the "value" will drop dramatically and that would mean the big boys can't make the "big bucks" they are now making. This is not like a lot of pills, it is something virtually anyone can grow - lol, that's why they call it (a) weed!
Now if by "big guys" you mean law enforcement; that does not seem like the best place to spend taxpayer dollars. But then, that's nothing new.
