In Washington the taxes collected go to health and social services.

There were supposed to be hundreds of millions going to school's infrastructures. I have read several places that less than 40 million has gone to schools. I do wonder how much extra $ is spent on law enforcement with the homelessness it has brought into the state. I have several friends who are principals and the junior high kids are bringing it into the schools in large quantities by way of chewables and other hard to detect goodies. I do believe that it needs to be readily available to those who need it for pain relief, but it is out of control how many businesses sell it.
