Cleaner cup possibly leads to excessive drinking (10)

I believe the answer is:

crapulence

'excessive drinking' is the definition.

'cleaner cup possibly' is the wordplay.
'possibly' is an anagram indicator.
'cleaner'+'cup'='cleanercup'
'cleanercup' with letters rearranged gives 'CRAPULENCE'.

'leads to' is the link.

(Other definitions for crapulence that I've seen before include "sloshed" , "Drinking" .)

I've seen this clue in The Independent.
