Yes, Colorado just passed Prop 122. https://ballotpedia.org/Colorado_Proposition_122,_Decriminal...

But it's not "legalized" in the way that weed is "legalized". It's "legalized" in that it's no longer an offense to purchase/obtain/possess/use shrooms; but it's still a crime to sell shrooms (except for supervised mental health treatment), so you still need to "know people" to get them.
