As the brain matures, experiences prune excess neural connections while strengthening those that are used more often. Many scientists think that this process contributes to the steady reduction in gray matter volume seen during adolescence (depicted as the yellow to blue transition in the figure). As environmental forces help determine which connections will wither and which will thrive, the brain circuits that emerge become more efficient. However, this is a process that can cut both ways because not all tasks are desirable. The environment is like an artist who creates a sculpture by chipping away excess marble; and just like bad artists can produce bad art, environments with negative factors (like drugs, malnutrition, bullying, or sleep deprivation) can lead to efficient but potentially harmful circuits that conspire against a person's well-being.

Alcohol dependence or abuse rates were shown to have no correspondence with any person's education level when populations were surveyed in varying degrees of education from ages 26 and older. However, when it came to illicit drug use there was a correlation, in which those that graduated from college had the lowest rates. Furthermore, dependence rates were greater in unemployed populations ages 18 and older and in metropolitan-residing populations ages 12 and older.
Nalmefene, an opiate antagonist that is similar in its chemical structure to naltrexone, is one of the most recent drugs being investigated for the treatment of alcoholism. Like naltrexone (sold as ReVia, Depade, or Vivitrol), nalmefene deprives the person struggling with substance use of the pleasurable feelings associated with drinking. But nalmefene is less toxic to the liver than naltrexone. As of 2013, nalmefene was still undergoing clinical trials through the U.S. National Institutes of Health before receiving FDA approval.

Drug addiction starts with drug use. Experimental use, recreational use, social use, occasional use, medical use – any use of an addictive substance for any purpose can and often does lead to a dependence upon that drug. While any and all drug use has the potential for harm, the most dangerous type of drug use in terms of the likelihood that it will lead to addiction, is the type that stems from a desire to numb pain or negative feelings or to cope with problems in one’s life.

Disulfiram (Antabuse®) interferes with the breakdown of alcohol. Acetaldehyde builds up in the body, leading to unpleasant reactions that include flushing (warmth and redness in the face), nausea, and irregular heartbeat if the patient drinks alcohol. Compliance (taking the drug as prescribed) can be a problem, but it may help patients who are highly motivated to quit drinking.
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)
