Problem
You are the case worker for a single mother (Mary) who has a 15yr old son (Toby). Mary is struggling with alcohol addiction and states she also smokes marijuana when her son is at school.
Mary has said that she hasn't worked since her son was born and had previously managed by doing odd jobs for friends and neighbours. However, Mary has said that now her son is older she would like to get a full-time job but is worried that she will not be successful due to her addiction.
When 'probing' further into Mary's addiction, you come to understand that she regularly has her first glass of wine with breakfast and states that without it she can't 'think' straight. Mary said she found a half-smoked marijuana joint in her son's room when she was cleaning, and she is worried that he maybe experimenting with drugs. Mary states that she would like to be able to stop drinking and smoking marijuana but every time she has tried before it hasn't worked.
