Of course the idea is to reduce overdoses; but man this seems like a tacit endorsement of drug use. If opioid use/abuse is the issue why would we subsidize safe centers to do drugs? Why wouldn't we fund more MAT centers to treat the addiction? Talk about NIMBY. Part of So Fla (Delray and others) are already like the Walking Dead with the amount of addicts, imagine having an injection site on the corner of your street.
I don't see the logic here, but thought it might make for an interesting debate/discussion
perhaps the answer to your question is contained within your post.
perhaps you need to not over think what the actual purpose of said sites are, and what they aren't, and that what they aren't, is because it isn't effectively possible.
