Wrong to consume heroin and crack in lively celebration (7)
I believe the answer is:
shindig
'lively celebration' is the definition.
(I've seen this before)
'wrong to consume heroin and crack in' is the wordplay.
'wrong' becomes 'sin' (I've seen this in another clue).
'to consume' is an insertion indicator.
'heroin' becomes 'H' (synonyms).
'and' says to put letters next to each other.
'crack in' becomes 'dig' (I can't explain this - if you can you should give a lot more credence to this answer).
'sin' placed around 'h' is 'shin'.
'shin'+'dig'='SHINDIG'
Can you help me to learn more?
(Other definitions for shindig that I've seen before include "Hooley" , "Noisy disturbance" , "Noisy knees-up" , "Bash" , "Hidings (anag) - party" .)
