Jason and Mark have been friends for the past 5 years.  For four of those five years Mark has battled addiction to alcohol.  Recently, Mark lost his job, his home, his marriage, and custody of his children due to his drinking habits.  As a result, Mark has realized that he no longer can deny the depth of his issues with alcohol.  Mark asks Jason, a licensed substance abuse counselor, to work with Mark to overcome his substance use issues.  Mark feels that the only way he can get better is by working with Jason as Jason has firsthand experience with Mark’s addiction.   Should Jason agree to be Mark’s substance abuse counselor?
