Alright, no state has legalized a distribution-model of marijuana. The most relaxed state is by far Alaska which has removed any penalties for possession of less than an ounce as long as you smoke it at home. You may not grow, sell, or buy it though, but once you have it, you are safe.
Denver, not the state of Colorado voted to do the same thing, but police in Denver still right tickets using state law... so nothing changed.

There are still court battles pitting California against the govs for their medical distribution program. Think about these battles on a whole new state-level scale.
