Those people may accept charge for treatment (7)
I believe the answer is:
therapy
'treatment' is the definition.
('therapy' can be a synonym of 'treatment')
'those people may accept charge' is the wordplay.
'those people' becomes 'they' (I've seen this before).
'may accept' is an insertion indicator.
'charge' becomes 'rap' (I have seen 'Criminal charge ' mean 'rap' so perhaps 'charge' could also mean 'rap').
'they' placed around 'rap' is 'THERAPY'.
'for' acts as a link.
(Other definitions for therapy that I've seen before include "See 7" , "They rap (anag.)" , "Healing treatment" , "Medical treatment" , "will do you good" .)
