Sailor isn't worried - he has strong drinks (9)

I believe the answer is:

absinthes

'strong drinks' is the definition.
(absinthe is a kind of strong drink)

'sailor isn't worried he has' is the wordplay.
'sailor' becomes 'ab' (abbreviation for able seaman).
'worried' is an anagram indicator.
'he has' becomes 'hes' (he's).
'isnt' with letters rearranged gives 'sint'.
'ab'+'sint'+'hes'='ABSINTHES'

(Another definition for absinthes that I've seen is " Drinks".)

I've seen this clue in The Independent.
