One drug wasted in sink (2,5)

Ross

I believe the answer is:

go under

'sink' is the definition.
(synonyms)

'one drug wasted' is the wordplay.
'wasted' indicates an anagram.
'one'+'drug'='onedrug'
'onedrug' anagrammed gives 'GO UNDER'.

'in' is the link.

(Other definitions for go under that I've seen before include "Become bankrupt" , "Sink" .)

I've seen this clue in The Sun.
