Being addicted to some harmful substances such as heroin can be life threatening. What is even worse, you might not realize that you are an addict until your family sends you for heroin detox simply because they care so much about you. There are two ways to deal with addictions: physical intervention and psychological intervention. It takes approximately 8 hours to get rid of an addiction with the help of 8 hour detox, but after the procedure a certified psychologist should also intervene to prevent a person from relapsing.
