Heroin detoxification, to ensure success, involves several components such as the acceptance and admittance on the part of the person affected that there is, indeed, a problem to be solved, and that the must enter a rehab center. The individual must be willing to avail professional medical help, and do whatever he can do be rehabilitated. It is common knowledge that a relapse can occur. Hence, both the patient, his family and friends, the physicians or other people concerned in the program must work as one to make the effort successful.
