Japanese food gets us high? Not entirely (5)
I believe the answer is:
sushi
'japanese food' is the definition.
(sushi is a type of Japanese food)
'gets us high? not entirely' is the wordplay.
'not entirely' indicates the answer is hidden within the clue.
'SUSHI' can be found hidden inside 'gets us high'.
(Other definitions for sushi that I've seen before include "Rice and raw fish wrapped in seaweed" , "Exotic food" , "rice dishes" , "put away in Japan" , "Rice, seafood cuisine" .)
