Bogus cure, often it's dodgy (11)
I believe the answer is:
counterfeit
'bogus' is the definition.
('counterfeit' can be similar in meaning to 'bogus')
'cure often it's dodgy' is the wordplay.
'dodgy' is an anagram indicator.
'cure'+'often'+'it'='cureoftenit'
'cureoftenit' anagrammed gives 'COUNTERFEIT'.
(Other definitions for counterfeit that I've seen before include "Forgery" , "Pretended, sham" , "Phoney" , "Sham, fake" , "Forge" .)
