Can this possibly prohibit injecting drug? (4)
I believe the answer is:
bean
'can this' is the definition.
The definition suggests a singular noun which matches the answer. I also know that 'can' relates to this answer.
'prohibit injecting drug?' is the wordplay.
'prohibit' becomes 'ban' (banning is a kind of prohibiting).
'injecting' is an insertion indicator.
'drug?' becomes 'e' (E is another name for ecstasy).
'ban' enclosing 'e' is 'BEAN'.
'possibly' is the link.
Can you help me to learn more?
(Other definitions for bean that I've seen before include "Fava, kidney or mung, say" , "Seed; head" , "Vegetable; coffee seed" , "Nut" , "Haricot, for example" .)
