What's in store at the chemist's? (4)
I believe the answer is:
drug
'chemist's?' is the 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?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for drug that I've seen before include "Perhaps an upper" , "LSD, say" , "Chemical medicament" , "Substance used in medicine, often abused" , "Medication" .)
