Turmoil in opium den man sorted out (11)
I believe the answer is:
pandemonium
'turmoil' is the definition.
(thesaurus)
'opium den man sorted out' is the wordplay.
'sorted out' indicates anagramming the letters.
'opium'+'den'+'man'='opiumdenman'
'opiumdenman' anagrammed gives 'PANDEMONIUM'.
'in' is the link.
(Other definitions for pandemonium that I've seen before include "State of chaos" , "Tumultuous uproar" , "Uproar, wild and noisy confusion" , "Chaos and confusion" , "havoc" .)
