The problem as summarized by the photo isn't drugs. The problem everywhere -- not just in Oregon -- is Human Overpopulation. The severity of it in Oregon has increased because of populations spilling over from elsewhere, most notably California. Sadly, Portland is finally a large city, thus it has the same issues all other large cities have. This overall problem of Human Overpopulation which is the root cause of pretty much every other problem in the entire world (climate change, wealth gap, dwindling resources, etc) is exacerbated by certain politicians opposing birth control.
