I want to know the answer to the following question:
Mrs. Dubose suffers from an addiction to what?
All the background I'm provided with is that "In a statement that foreshadows Atticus' motivation for defending Tom Robinson and describes Mrs. Dubose, who is determined to break herself of a morphine addiction, Atticus tells Jem that courage is "when you're licked before you begin but you begin anyway". Is that enough to answer the question?
Answer: yes
