Decriminalized? As I noted in my other comment, it's still illegal federally, and the state and federal governments are separate sovereigns that can and do independently create and enforce laws (subject to various federal constitutional limitations).
But there are recreational cannabis dispensaries, collecting state sales and cannabis taxes, in (almost literally) every other strip mall commercial district in many US states. They might be more common than liquor stores, honestly.
That fits no practical definition of "illegal" in an ordinary person's daily life.
