The green line represents arrests in the 500 meter area around the unauthorized consumption site. The dotted line delineates when the site opened: five years of data before, five years of data after. “What you see there is that it was actually increasing in that neighborhood, steadily, the five years before. And then really, the line was very clear, that after it opened, it steadily started decreasing,” said Alex Kral, a researcher who co-authored the study. The red line shows arrests in a similar neighborhood during the same time period. “our main point here is that, you know, at worst, the site looks just like another neighborhood that doesn’t have this,” Kral said.
