Jacket for cigarette? (6)
I believe the answer is:
reefer
This clue is a double definition.
'jacket' is the first definition.
(I've seen this before)
'cigarette?' is the second definition.
(I've seen this before)
'for' acts as a link.
(Other definitions for reefer that I've seen before include "roll of hemp" , "Double-breasted jacket for a man" , "Jacket for a sailor" , "Canvas trimmer" , "packed with cannabis?" .)
