Take a drag and give a smile? (5,2)
I believe the answer is:
light up
This clue is a double definition.
'take a drag' is the first definition.
(as in lighting up a cigarette)
'give a smile?' is the second definition.
(light up can mean to look happy)
'and' acts as a link.
(Other definitions for light up that I've seen before include "Become animated" , "Start (a cigarette)" , "Display joy" , "Start dragging in" , "Start smoking" .)
