Dried leaves for smoking (7)
I believe the answer is:
tobacco
'dried leaves for smoking' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for tobacco that I've seen before include "Dangerous plant" , "Pipe leaves" , "20 [CASTRO] 's favourite leaves" , "Put that in your pipe and smoke it!" , "Addictive substance" .)
