a story

My stepbrother tried to quit smoking,
Some old man said: boil it and drink everything.
Old way or something.
Then my stepbrother did exactly the same.
It was old unproven way.
He got sick almost immediately,
His mom found very fast medicine for their dog and women.
Dog had more.
Make a long story short, skipping complains and something else with medical terminology d. and v,
Doctor in emergency said: don't smoke any more.
