Took a stimulant, being exhausted (4)

I believe the answer is:

used

This clue is a double definition.

'took a stimulant' is the first definition.
(used drugs)

'being exhausted' is the second definition.
(I've seen this before)

(Other definitions for used that I've seen before include "Put to a purpose" , "Brought into service" , "Sued (anag.)" , "Second-hand, not new" , "Exploited group" .)

I've seen this clue in The Guardian.
