It's just very weird that everyone is expected to just ignore their discomfort as we adjust our lives around the idea that people will inject drugs in bathrooms rather than say if its that common we need to change our drug policy. As you point out, we have things that if not 'solve' certainly help. That's before you get into how a safe injection site could help with larger problems like dirty needles spreading disease or making services available to people wary of the government. Its reminds me of a disfunctional family, those who try to talk about it directly are treated as the problem, while everyone is expected to adjust quietly around it without acknowledging that it's happening much less that the constant effort is a sign something is wrong.
