Dope found in rainforest... (4)

I believe the answer is:

info

'dope' is the definition.
(dope can informally mean information)

'in rainforest' is the wordplay.
'in' indicates a hidden word.
'INFO' is hidden within 'rainforest'.

'found' acts as a link.

(Other definitions for info that I've seen before include "counsel?" , "Gen (abbr)" , "What's known" , "Facts; knowledge gained" , "details" .)

I've seen this clue in The Irish Times.
