High priest's tone delights recruits (6)
I believe the answer is:
stoned
'high' is the definition.
(on drugs)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for stoned that I've seen before include "High; intoxicated" , "On a drug-induced high" , "Like Olive perhaps" , "High on a drug" , "Slangily drunk or biblically executed" .)
