Drugs carts coin around (9)
I believe the answer is:
narcotics
'drugs' is the definition.
(I know this)
'carts coin around' is the wordplay.
'around' is an anagram indicator.
'carts'+'coin'='cartscoin'
'cartscoin' is an anagram of 'NARCOTICS'.
(Other definitions for narcotics that I've seen before include "Addictive drugs" , "Drugs that cause sleep or drowsiness" , "Stupefying drugs" .)
