Container — sort of basin or pot (8)
I believe the answer is:
cannabis
'pot' is the definition.
(synonyms)
'container sort of basin' is the wordplay.
'container' becomes 'can' (can is a kind of container).
'sort of' is an anagram indicator.
'basin' is an anagram of 'nabis'.
'can'+'nabis'='CANNABIS'
'or' acts as a link.
(Other definitions for cannabis that I've seen before include "illegal drug supply" , "Hemp plant, illegal intoxicant drug" , "Smoked drug" , "Hash" , "Most commonly used (mostly) illicit drug" .)
