For your information state constitutions existed way before the federal constitution. Every state has it's own constitution, each constitution states the functions, structure, and role in state and local governments. State constitutions can continually change upon the will and vote of the population of that state. State constitutions affect people's lives on a daily basis whereas the federal constitution does not. It's the states and local government ordinances that determine the majority of the rules we live by with each state having varying rules. Even if the federal government would decide to make marijuana legal it does not mean that states have to legalize it, it would be up to the will of the voters to change state laws. I know that has to be hard for you to come to grips that each state already allows for citizens to participate in what their "communities" can and cannot do more so than the federal government, it sort of blows that forming communities instead of governments theory apart because it's already implemented within state and local governments.
