Kind, has the dope let off (6)
I believe the answer is:
gentle
'kind' is the definition.
(I've seen this in another clue)
'the dope let off' is the wordplay.
'the dope' becomes 'gen' (both can mean information).
'off' indicates an anagram.
'let' anagrammed gives 'tle'.
'gen'+'tle'='GENTLE'
'has' acts as a link.
(Other definitions for gentle that I've seen before include "Kind - maggot" , "Merciful -- grub" , "Jane Eyre's kind person with a book? -- eternal greed (anag)" , "Mild, moderate" , "Soothing - light" .)
