Can new basin be pot? (8)

Ross

I believe the answer is:

'be pot?' is the definition.
(I've seen this before)

'can new basin' is the wordplay.
'new' is an anagram indicator.
'basin' is an anagram of 'nabis'.
'can'+'nabis'='CANNABIS'

(Other definitions for cannabis that I've seen before include "Soft drug", "Ban Incas from using this drug", "Grass", "Pot", "Most commonly used (mostly) illicit drug".)
