Consuming ecstasy, drink and dance (4)
I believe the answer is:
leap
'dance' is the definition.
(thesaurus)
'consuming ecstasy drink' is the wordplay.
'consuming' indicates putting letters inside.
'ecstasy' becomes 'e' (informal term for the drug).
'drink' becomes 'lap' (lapping is a kind of drinking).
'e' put within 'lap' is 'LEAP'.
'and' is the link.
(Other definitions for leap that I've seen before include "Jump suddenly" , "Basket" , "identify extra day?" , "Jump, spring" , "Sudden bound" .)
