Today, New York Mayor Bill de Blasio's administration announced through the New York Times that it may stop making arrests for low-level marijuana possession, opting instead to issue tickets without detaining the suspect. This would feel like an important step toward reasonable weed policy if New York state hadn't already mandated it 37 years ago.

Several months ago, Brooklyn District Attorney Ken Thompson announced his plan to stop prosecuting small-time pot possession arrests, and this week, he'll begin to carry it out, effectively enacting a limited version of legalization in the borough.
