Source of marijuana in nick gets support (7)
I believe the answer is:
armrest
This clue might be a double definition.
'source of marijuana in nick' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'support' is the second definition.
(I know that armrest is a type of rest)
'gets' is the link.
Can you help me to learn more?
(Other definitions for armrest that I've seen before include "giving a member support" , "Support attached to the side of a chair" , "Part of a carver chair" , "Side part of chair" , "Support for one member" .)
