Took drugs, thought to blow money (4)
I believe the answer is:
used
'took drugs' is the definition.
(to use can mean to take drugs)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for used that I've seen before include "worked unfairly" , "cast off" , "Second-hand; exploited" , "Second-hand, not new" , "Manipulated American editor" .)
