Caught, possesses ecstasy, being run after (5)
I believe the answer is:
chase
'run after' is the definition.
(thesaurus)
'caught possesses ecstasy' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'possesses' becomes 'has' ('have' can be a synonym of 'possess').
'ecstasy' becomes 'e' (informal term for the drug).
'c'+'has'+'e'='CHASE'
'being' acts as a link.
(Other definitions for chase that I've seen before include "Pursuit" , "Pursue, run after" , "grave, as before?" , "Composed type accommodated in this" , "Follow" .)
