APOTHECARY: Put this in any liquid you wish and drink it down. If you had the strength of twenty men, it would still kill you instantly.
ROMEO: There's your gold. Money is a worse poison to men's souls and causes more deaths in this hateful world than these poisons you are forbidden to sell.
I have sold you poison. You have sold me none.
Farewell. Buy yourself food and put flesh on your bones.
You are medicine, not poison, and I will take you to Juliet's grave.
For there I must use you.
