Fix up men with drug on break (7)
I believe the answer is:
restore
'fix up' is the definition.
(thesaurus)
'men with drug on break' is the wordplay.
'men with' becomes 'or' (I've seen this in other clues).
'drug' becomes 'e' (E is another name for ecstasy).
'on' means one lot of letters go next to another.
'break' becomes 'rest' (a rest is taking a break).
'or'+'e'='ore'
'ore' put after 'rest' is 'RESTORE'.
(Other definitions for restore that I've seen before include "Refurbish" , "Bring back, reinstate" , "Strengthen" , "hand it back?" , "Bring back; renovate" .)
