The product is Schedule 1 at the Fed level. That is still very much illegal no matter what the states do. But the state can choose not to pursue law enforcement and/or prosecution. And that is what decriminalization is.

The States are at the mercy of the Fed schedule. States can do a lot of things. Legalize is not one of them. The best a state can do is decriminalize.

Put another way, as we all know, these dispensaries are overflowing rich in cash. Why? Because they can't get bank accounts? Why? Because of a lack of true legalization. Again, this is the difference between legalization and decriminalization.
