Tobacco usefully wrapped (5)
I believe the answer is:
cigar
'tobacco' is the definition.
(cigar is a kind of tobacco)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for cigar that I've seen before include "Smoked item" , "Corona, eg" , "Close, but no ___ !" , "Havana, say" , "Tobacco product" .)
