Cocaine, grass and ecstasy put in a container (5)
I believe the answer is:
crate
'put in a container' is the definition.
'crate' can be an answer for 'container' (crate is a kind of container). I'm unsure of the 'put in a' bit.
'cocaine grass and ecstasy' is the wordplay.
'cocaine' becomes 'C' (drugs abbreviation).
'grass' becomes 'rat' (both can mean a snitch or informer).
'and' says to put letters next to each other.
'ecstasy' becomes 'E' (informal term for the drug).
'c'+'rat'+'e'='CRATE'
Can you help me to learn more?
(Other definitions for crate that I've seen before include "Old soldiers might be found in this" , "Carton; old plane" , "Old car" , "Dilapidated vehicle" , "Box for shipping" .)
