Lure specialist with crystal meth (6)
I believe the answer is:
entice
'lure' is the definition.
(synonyms)
'specialist with crystal meth' is the wordplay.
'specialist' becomes 'ent' (abbreviation of ear nose and throat).
'with' is a charade indicator (letters next to each other).
'crystal meth' becomes 'ice' (I can't justify this - if you can you should give a lot more credence to this answer).
'ent'+'ice'='ENTICE'
Can you help me to learn more?
(Other definitions for entice that I've seen before include "Persuade with promise of reward" , "Allure" , "Tempt, lead astray" , "act like clickbait" , "Trap" .)
