Editor with viewpoints on drugs? (10)

I believe the answer is:

substances

'drugs?' is the definition.
(I've seen this before)

'editor with viewpoints' is the wordplay.
'editor' becomes 'sub' (short for subeditor).
'with' is a charade indicator (letters next to each other).
'viewpoints' becomes 'stances' (I've seen this in another clue).
'sub'+'stances'='SUBSTANCES'

'on' acts as a link.

(Another definition for substances that I've seen is " Drugs (illegal)".)

I've seen this clue in The Telegraph.
