I thought this was a good article, and together with the article about Portland last week, highlights a change a lot of those "on the left" (myself included) are coming to: there are significant negative side effects to decriminalization that are worse than many expected.

Personally, as someone who was strongly in favor of decriminalization, my mind changed a bit a couple years ago when I went through the pedestrian mall in downtown Denver. I have nothing against weed use, but walking down there was like "zombieland": tons of people walking around completely stoned out of their minds.

This doesn't mean I'm for "recriminalization", but public use was never legalized (at least in CO), but those rules are now all but completely ignored.
