Thank you for your query.
As you rightly mentioned smoking
hurts your throat. The throat get affected and in turn the eustachian tube connecting the middle ear to the throat gets blocked. This blockage causes middle ear infection
and you can have the enlarged lymph node
in the neck due to it. I suggest that you get your throat, ear and lymph noded examined by a doctor who shall advise you the correct course of management.
As you are aware of the problems by taking cannabis why not stop it. You are capable of doing it and I know will do it for your own benefit.
I hope I have answered your query to your satisfaction.
Wishing you all the best.
