Repressive measure of drug bust? (9)
I believe the answer is:
crackdown
'repressive measure' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?
'drug bust?' is the wordplay.
I cannot really understand how this works, but
'drug' could be 'crack' (crack is a kind of drug) and 'crack' is found within the answer.
The remaining letters 'down' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for crackdown that I've seen before include "Draconian measures" , "getting tough" , "Repression" , "Repressive action" , "severe action" .)
