Heavenly drink producing trance when drunk (6)
I believe the answer is:
nectar
'heavenly drink' is the definition.
(I've seen this before)
'trance when drunk' is the wordplay.
'when drunk' indicates anagramming the letters (I've seen this in other clues).
'trance' is an anagram of 'NECTAR'.
'producing' acts as a link.
(Other definitions for nectar that I've seen before include "Recant (anag.)" , "Bees drink it" , "That's sweet" , "Divine beverage" , "Drink of gods and insects" .)
