Drug is removed with the fingers (7)
I believe the answer is:
digital
'with the fingers' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for digital that I've seen before include "form of technology" , "Works with through numerals, like watch" , "Using fingers" , "As most computers" , "Of watch, showing time in numbers" .)
