Stupefied, practising social distancing? (6,3)
I believe the answer is:
spaced out
This clue is a double definition.
'stupefied' is the first definition.
'practising social distancing?' is the second definition.
(Other definitions for spaced out that I've seen before include "Not quite all there?" , "in a dazed state" , "Disorientated through drug use" , "Separated" , "Placed well apart - unaware of one's surroundings" .)
