What role do Rehabilitation Centres have in addressing addiction in India?

Addiction is a deadly disease that does not have any sympathy for you or your loved one. Many times when a family brings their patient to me, I see their pain and hear their sadness through the words they do not express. There are so many de-addiction centres in India, working on this problem. Throughout India there is a cry for help going on, thousands of families are unable to comprehend what is going on with their loved ones, is it a habit making them drown their lives or is it a disease?
