Crack, Viagra, injecting cocaine and ecstasy at church residence … (8)
I believe the answer is:
vicarage
'church residence' is the definition.
(I've seen this before)
'crack viagra injecting cocaine and ecstasy' is the wordplay.
'crack' indicates anagramming the letters.
'injecting' indicates putting letters inside.
'cocaine' becomes 'c' (drugs abbreviation).
'and' means one lot of letters go next to another.
'ecstasy' becomes 'e' (informal term for the drug).
'viagra' anagrammed gives 'viarag'.
'viarag' going around 'c' is 'vicarag'.
'vicarag'+'e'='VICARAGE'
'at' acts as a link.
(Other definitions for vicarage that I've seen before include "Minister's place" , "cleric's place" , "Parish residence" , "Church dwelling" , "6's residence" .)
