It's not just the drug problem, it's the lack of mental health care for those who can't afford it. I remember when Washington State (I grew up and spent my early adult years in Spokane), along with many other states, emptied the state mental health hospitals in the 70's and shut them down to save money. The people who were in those institutions were released, many of them poor and without any way of providing for themselves. What do you think they did? They hit the streets and became homeless. There are homeless people with severe mental health problems all across this nation and now nothing is done until one of them goes over the edge. IOW, nothing is done until it's too late. Some states try to do something about it, California for one, but the problems and numbers of people who need help are overwhelming. These homeless turn to drugs as a way to numb themselves from the reality of their shitty lives. Some states choose to do absolutely nothing except toss them in jail for a bit when they break the law. Wow, room, warmth and food for a bit and then they are back on the streets. Some kind of help that is.
It's only going to get worse the longer we go without doing anything about it. The sane public is going to have to buck up and pay the state to take care of the mentally ill or they are going to have to learn to accept seeing their communities deteriorate. The wealthy, well to do and their politicians who could do something about this mess have pretty much isolated themselves from the problem so there is no sense of urgency for them to do anything.
We either care enough to do something about this or we suck it up and eat the shit sandwich.
