Marijuana was not legalized completely in the states of Washington and Colorado, it was just an initiative for it to happen. You still can't go onto the streets and smoke or you will be arrested. It's still against the law.

There is still a long ways to go until it's legal, this was just a pretty good stepping stone I guess for it to be.
