Havana export (5)
I believe the answer is:
cigar
'havana export' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cigar that I've seen before include "Cylinder of tobacco" , "Eg, a cheroot" , "Something to smoke" , "Close, but no ___ !" , "Smoked item" .)
