in the 1990s there was a trend of NHS staff with socially conservative views about drugs passing on info to cops, but from what I’ve heard more recently (and I’ve got relatives working in NHS emergency depts) their confidentiality rules have been tightened up and they are not allowed to do that any more
They never were in the first place but were taking advantage of the harder anti-drug social views and less monitoring by management that occured in the John Major era.
the only time NHS frontline staff can call cops for backup is if they think they are going to be attacked on entry to an area (be aware though at raves they tend to want police backup as people get paranoid of any uniform they see there) , and (other than really serious things like gunshot wounds or stabbings) they are discouraged from passing info to law enforcement unless the patient requests it (such as a case of drink spiking).
In 99% of cases if people are within a group of friends and someone is ill they can call an Ambulance for an overdose victim without any risks to themselves…
they will just get an NHS paramedic unit and nothing else like cops will arrive.
