Weird and revolting rage suppressed by drugs (5)
I believe the answer is:
eerie
'weird' is the definition.
(both can mean strange or unsettling)
'revolting rage suppressed by drugs' is the wordplay.
'revolting' says the letters should be written backwards.
'rage' becomes 'ire' (I've seen this before).
'suppressed by' is an insertion indicator (I've seen this in other clues).
'drugs' becomes 'ee' (an abbreviation for ecstasy written twice).
'ire' inserted into 'ee' is 'eiree'.
'eiree' written backwards gives 'EERIE'.
'and' is the link.
(Other definitions for eerie that I've seen before include "Spine-tingling" , "Spooky, creepy" , "Bloodcurdling" , "Awesome" , "Unnerving" .)
