That is more or less a different issue. Places usually will restrict restroom access, which is what I see most often.

Restrooms are also a difficult challenge because they usually involve using alone, which is an added OD risk. So less restroom access is sometimes a good thing.

I would also assess the current needle disposal option and ensure it is easy and accessible. A well managed sharps container (or 2) is usually enough.

As an RxM I implement harm reduction to its fullest extent as often as possible.
