Drug container? (3)
I believe the answer is:
pot
I believe this is a double definition.
'drug' is the first definition.
(slang term for cannabis)
'container' is the second definition.
(pot is a kind of container)
(Other definitions for pot that I've seen before include "Cooking vessel, plant container and street drug" , "prize" , "Storage container" , "Street name for marijuana" , "Cylindrical container" .)
