Drugs said to relieve anxiety (4)
I believe the answer is:
ease
'relieve anxiety' is the definition.
'ease' can be an answer for 'relieve' (easing is a kind of relieving). I am not sure about the 'anxiety' bit.
'drugs said' is the wordplay.
'drugs' becomes 'es' (ecstasy tablets).
'said' indicates a 'sounds like' (homophone) clue.
'es' sounds like 'EASE'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for ease that I've seen before include "Loosen - relax" , "composure" , "Leisure, relaxation" , "Comfort or freedom from difficulty" , "Rest and leisure" .)
