Drugs a poet is trying (7)

I believe the answer is:

opiates

I'm a little stuck... Click here to teach me more about this clue!

'drugs a poet is trying' is the definition.
I can't judge whether this definition defines the answer.

'drugs a poet is' is the wordplay.
'drugs' is an anagram indicator (I've seen 'drugged' mean this).
'a'+'poet'+'is'='apoetis'
'apoetis' with letters rearranged gives 'OPIATES'.

Can you help me to learn more?

(Other definitions for opiates that I've seen before include "Narcotic drugs" , "Branch of narcotics" , "Makes dull" , "Sedative drugs" , "Is a poet (anag.)" .)

I've seen this clue in the Sydney Morning Herald.
