People who have a long-term alcohol or drug habit usually have developed a strong psychological addiction to these substances, and it is very difficult to stop them from doing this, no matter how much effort they try. In such cases, inpatient treatment proves to be extremely effective, as patients are kept safe and have all the personal care they need while in the hospital or in the drug rehab center. The support from other family members, friends, and caregivers is most important during this period of time.
