I read an article recently about the failure of this measure. It attributed a large part of the failure to a lack of training. For example, police were significantly less likely to hand out tickets for minor possession than they were to make arrests (before the measure), because they didn’t see what the point was. To them, it was just a significantly more lenient system and the article argued that training could’ve helped them to see that the ticket isn’t meant to be a punitive measure, but a way to pull people towards the increased support.
The police were essential outreach, but they weren’t given training to understand how their role was different. The tickets that were being handed out were a standard one, instead of a custom ticket made for this new citation, which would’ve explained that you can get the ticket waived if you call the support number listed.
