Grass, coke and E smuggled by artist whose mum got framed? (7-6)
I believe the answer is:
whistle-blower
'grass' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for whistle-blower that I've seen before include "Person with inside information making public some illicit activity" , "Informer on illicit activities" , "One who exposes wrongdoing" , "Teller of tales to the authorities - referee?" , "One who informs on malpractice" .)
