Refraining from need to carry can (10)
I believe the answer is:
abstinence
'refraining' is the definition.
(thesaurus)
'need to carry can' is the wordplay.
'need' becomes 'absence' (I've seen this before).
'to carry' is an insertion indicator.
'can' becomes 'tin' ('tin' can be a synonym of 'can').
'absence' going around 'tin' is 'ABSTINENCE'.
'from' is the link.
(Other definitions for abstinence that I've seen before include "Staying away from" , "Teetotalism" , "giving it up" , "Non-partaking (of liquor)" , "Temperance" .)
