Dope pockets pound in depressed Scots area (4)
I believe the answer is:
glen
'depressed scots area' is the definition.
(Scottish term for a piece of low land)
'dope pockets pound' is the wordplay.
'dope' becomes 'gen' (both can mean information).
'pockets' is an insertion indicator.
'pound' becomes 'L' (the pound sign is based on an L).
'gen' placed around 'l' is 'GLEN'.
'in' is the link.
(Other definitions for glen that I've seen before include "Scottish mountain valley" , "Highland valley" , "Valley, dale" , "Campbell perhaps" , "Depression in Scotland" .)
