No one wants to be a drug addict or alcoholic; no one wants to be controlled by a substance and feeling hopeless. The drug addict's family and friends most commonly ask these drug rehab questions: how could my son, daughter, father, mother, sister, brother or friend become a liar, a thief, someone who cannot be trusted? And why won't they stop?

What you need to understand about drug addiction/drug rehab is that alcohol and addictive drugs are basically painkillers. Drugs chemically kill physical or emotional pain and alter the mind's perception of reality. They make a person numb to the pain they want to be rid of, but drugs also make them numb to all other emotions, including happiness and life in general.

For a person to start taking drugs there must first exist an underlying situation of unhappiness, a sense of hopelessness, or physical pain. Since the substances that they are taking to 'kill the pain' are chemicals and toxic to the body, they actually add in creating depression. A good alcohol and drug rehab program will include detox, which aims at ridding the body and mind of the toxins accumulated by drug use.

Bodies need vitamins, minerals, oils and water to function properly; when they are deprived of proper nourishment they become very depleted. The vitamin deficiencies will cause the person to experience problems sleeping, depression, physical aches and pains, and severe mood swings.
