Neurons communicate with each other by sending messages along axons and dendrites via electrical impulses. The axons turn these impulses into chemical signals, sending neurotransmitters across synapses. The receiving dendrite then converts neurotransmitters back into the right electrical signals, so we understand the message; for example, that bite of pie was delicious, I’ll take another one. These exchanges happen countless times in the brain, and they control mood, behavior, movement, and cognition.
People who are addicted to drugs need to be in a drug-free environment with people who will hold them accountable for their goal of getting off drugs. Drug rehab may begin with detoxification, which helps the addict rid his or her body of the drugs and treat any withdrawal symptoms. Not everyone needs to go through detox, but detox alone is not enough treatment to effectively break the addictive cycle long-term. Once detox is completed, the real work of addiction treatment begins.
Aftercare services are primarily designed to help recovering alcoholics maintain their sobriety once their treatment has finished. According to the National Center for Biotechnology Information (NCBI), a good after-care service can make a who difference to whether a person's alcoholism treatment is successful. Some states provide sober houses, which provide somewhere to live for people who are trying to stay sober. While it is not formal treatment, staff members who supervise the houses will remind individuals if they have a therapy appointment or support group meeting. They also, along with other residents, offer support and the chance to live in a completely alcohol-free environment.
Where alcoholics are concerned, their brains have become so accustomed to dealing with alcohol that the volume of chemicals being produced to overcome the effects of alcohol is excessive. As blood alcohol levels start to fall, those same brain chemicals start causing unpleasant withdrawal symptoms. The only two solutions are to either consume more alcohol or wait it out until the body readjusts.

Substance abuse therapy: Used as a part of many inpatient and outpatient programs, therapy is one of the cornerstones of drug addiction treatment. Individual, group and family therapy help patients and their loved ones understand the nature and causes of addiction. Therapy teaches coping strategies and life skills needed to live a productive, sober life in the community. For individuals with a co-occurring mental illness, intensive psychotherapy can also address psychiatric symptoms and find the underlying issues that contribute to addiction.
