The drugs said to bring you comfort? (4)
I believe the answer is:
ease
'comfort?' is the definition.
(easing is a kind of comforting)
'the drugs said' is the wordplay.
'the drugs' becomes 'es' (E is a term for an ecstasy pill).
'said' shows a homophone (sound like).
'es' is a homophone of 'EASE'.
'to bring you' acts as a link.
(Other definitions for ease that I've seen before include "Lack of worry or agitation" , "'Comfort, rest (4)'" , "Alleviate" , "Move gently or carefully" , "Free from pain" .)
