As taken for a trip? (4)
I believe the answer is:
dope
'trip?' is the definition.
The definition and answer can be both related to consumption as well as being verbs in their base form.
Perhaps you can see an association between them that I can't see?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for dope that I've seen before include "Aircraft fabric varnish" , "cheat thereat?" , "Information, fool" , "Dolt -- drug" , "Idiot; information" .)
