Except most people are far too ignorant to realize that federal law will still trump state law, even if California passes Prop 19. The Department of Justice has said they will not follow state law so possession will still be a criminal offense. Therefore, most selling will still be underground, therefore the tax revenue on marijuanna will be nearly impossible to collect, yielding not much money for the state.
I realize I will probably get roasted for this, but whatever. This is clearly one viewpoint, you dont have to believe it. Just realize the implications of the proposal. I just really do not see what it will change.
