Quest,
Has the person you speak of ever had a job, attended college? The first thing I think is one shouldnt always blame the addiction for a person being unmotivated to live a somewhat normal life. Maybe there are other issues? Or maybe this person never had any direction in their life ? Lots of people who are addicted to drugs still work jobs, go to school, have a home, pay their bills. I guess what Im saying is be sure to see the person for who they are, and dont assume drug use is the whole problem. It may be a symptom of a bigger issue.
