Remains with street user encountering cold turkey (7)
I believe the answer is:
carcass
'remains' is the definition.
(thesaurus)
'street user encountering cold turkey' is the wordplay.
'street user' becomes 'car' (I can't explain this - if you can you should give a lot more credence to this answer).
'encountering' is a charade indicator (letters next to each other).
'cold' becomes 'c' (eg on taps).
'turkey' becomes 'ass' (I've seen this before).
'car'+'c'+'ass'='CARCASS'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for carcass that I've seen before include "Dead body of animal" , "Framework" , "Dead animal's body" .)
