Fag or gasper (9)
I believe the answer is:
cigarette
I believe this clue is a double definition.
'fag' is the first definition.
(synonyms)
'gasper' is the second definition.
(I've seen this before)
(Other definitions for cigarette that I've seen before include "tobacco in consumable form" , "Cylinder of tobacco" , "Fag, coffin nail" , "Gasper" , "Fag, smoke" .)
