Obtain smokers' instruments (8)
I believe the answer is:
bagpipes
'instruments' is the definition.
(bagpipe is a kind of instrument)
'obtain smokers'' is the wordplay.
'obtain' becomes 'bag'.
'smokers'' becomes 'pipes' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'bag'+'pipes'='BAGPIPES'
Can you help me to learn more?
(Other definitions for bagpipes that I've seen before include "Scottish musical instrument" , "Traditional musical instrument of Scotland" , "Scottish wind instrument" , "Instrument associated with Scotland and Ireland" , "Wind instrument with a chanter" .)
