The most interesting concept learned from Sheff’s novel is that drug addiction can trigger psychological challenges in families. As evidenced in the book Sheff is emotionally disturbed by Nick’s drug behavior which has compromised his life. He experiences denial feelings since he cannot accept that his son is addicted to methamphetamine substance (Sheff, 2008). Sheff later contracts a brain hemorrhage due to depression while reflecting on his son’s drug behavior. This scenario reveals the emotional challenges parents and guardians suffer while salvaging their children from drug addiction.
