Historically, drug addiction and those suffering with it were maligned as morally weak people who made bad choices. This pure behavioral model, however, fails to account for the biological changes that addiction triggers in the body and brain. Furthermore, it overlooks the issue of comorbidity; many people who are addicted to drugs also suffer from mental health problems and use drugs to self-medicate for those problems.
The first step in treatment is brief intervention. The physician states unequivocally that the patient has a problem with alcohol and emphasizes that this determination stems from the consequences of alcohol in that patient's life, not from the quantity of alcohol consumed. Emphasizing the effects on family, friends, and occupation, as well as any physical manifestations, is important. Pointing out that loss of control and compulsive use indicate alcohol dependence also is important.
Certain drugs (like cocaine, heroin, and methamphetamines) are infamous for how they can mess up the brain. Most people know to beware of their potency and danger. Other substances (such as alcohol, marijuana and painkillers) tend to be viewed quite differently. For many Americans, they are deemed to be much less dangerous. But is this view accurate?
In order to effectively address drug addiction as well as the co-occurring issues that may be underlying the problem, most patients will require residential or inpatient care. At a residential treatment program, the addicted patient will live at the treatment facility with access to 24-hour care and support that can be critical in helping them to avoid relapse in the early stages of recovery.

Stimulants, such as tobacco, cocaine or prescription amphetamines, stimulate the brain and nervous system, causing increased alertness. Depressants, such as barbiturates and benzodiazepines, slow activity in the brain and nervous system, causing relaxation. Hallucinogens, such as LSD and PCP, drastically disrupt the way the brain and nervous system communicate, causing hallucinations. Rehab: Last Week Tonight with John Oliver (HBO)
