Drink and drugs (4)
I believe the answer is:
coke
I believe this is a double definition.
'drink' is the first definition.
(Coke is an example)
'drugs' is the second definition.
(cocaine)
'and' acts as a link.
(Other definitions for coke that I've seen before include "Carbon fuel" , "Drug (abbr) - soft drink (abbr)" , "Carbonised fuel residue" , "Drink - drug - solid-fuel product" , "Substance left after gas and tar have been extracted from coal" .)
