A residential rehab can be suggested in order to help the person end his or her addiction. However, the whole process of convincing that person would be so much difficult. Remember that it is an addiction and ending it is really tough. But if you send him or her to some sessions of counseling and all, it would be easier for him to go for the rehab treatment.
In a rehab center, the patient is treated from the substance addiction while being around his or her peers. This kind of setting actually works in a positive way for the patient since he or she will not find the rehab center as a place of torture. At the end of the sessions, the patient will learn how to resist the temptations of such substances.
