Again experienced taking ecstasy, being liberated (8)
I believe the answer is:
relieved
'being liberated' is the definition.
(I've seen this before)
'again experienced taking ecstasy' is the wordplay.
'again' becomes 're' (prefix meaning 'again').
'experienced' becomes 'lived' (living is a kind of experiencing).
'taking' indicates putting letters inside.
'ecstasy' becomes 'E' (informal term for the drug).
'lived' enclosing 'e' is 'lieved'.
're'+'lieved'='RELIEVED'
(Other definitions for relieved that I've seen before include "Thankful" , "Raised siege - made to feel better" , "destressed" , "Grateful" , "Given a break" .)
