What is your response, when someone tells you drinking or taking drugs is merely a habit and not an addiction? Is there a fine line between the two or does it mean the same thing? Personally, I feel the two are the interchangeable terms, but I am not an expert. I am, just someone who has dealt far too many times with family member and friends falling astray to addiction. Seeing them break a "habit" is far and in between. For them to remain clean proves to be difficult at best, and sometimes impossible without professional help. What I do understand is that the fear they will fall back into their behavior pattern of destruction is possible. Especially, if they take their addiction or habit too lightly without thinking about the consequences.
