Drug report (5)
I believe the answer is:
crack
I believe this is a double definition.
'drug' is the first definition.
(I know that crack is a stimulant)
'report' is the second definition.
(thesaurus)
(Other definitions for crack that I've seen before include "Chat" , "Break sharply; a joke" , "Try" , "Joke; split" , "First-rate" .)
