Drug Addiction
Drug addicts are typically those individuals who are addicted to some substance other than alcohol. Drug addiction is a three stage process according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). They are preoccupation/anticipation, binge/intoxication, and withdrawal/negative affect. The Drug Addict, as opposed to the alcoholic, can be addicted to anything. It is common for drug addicts to have a “drug of choice,” or a particular drug that they prefer over other drugs. There are typically “upper” people who prefer stimulant drugs such as cocaine and/or methamphetamine, and there are “downer” people who prefer drugs such as heroin, prescription pain killers, and marijuana. Recently there has been an influx of multidrug addicts who use both uppers and downers.
The drug addict can also be addicted to alcohol and many drug addicts who assume that they are not alcoholics and attempt to drink without doing drugs find this a difficult task to accomplish. Many drug addict are alcoholics and visa versa.
Alcohol Addiction
There are many types of alcoholics. Some are binge drinkers and others have developed into daily drinkers. According to the DSM-IV, the alcoholic is someone who continues to drink despite negative consequences. Often the dependent alcoholic will develop severe withdrawal and tolerance to alcohol. The alcoholic will also have a preoccupation with drinking.
It is currently unclear what causes a person to become an alcoholic, but the general consensus is that it is a combination of environmental and genetic factors. Many people assume that a person must enjoy alcohol to be an alcoholic, but this is not true. An alcoholic may detest alcohol, but drink it anyway. An alcoholic drinks alcohol essentially because they like the effect produced by alcohol.
Coke Addiction
Cocaine is essentially a dopamine reuptake inhibitor. It suppresses appetite, produces a euphoric feeling, and increases energy. Cocaine can be smoked (freebasing), inhaled (Insufflation), or injected. Often people begin using the drug recreationally by inhaling into the nasal passage (snorting or sniffing). Cocaine is a highly addictive drug. People who use the drug only once or twice can become addicted to the drug physically. Cocaine is almost never pure. Cocaine is mixed with other substances such as baby laxative by dealers looking to increase their profit.
Crack Addiction
Crack is the most addictive form of cocaine. It produces and intense high that only last for minutes. Only half of Crack is made up of actual cocaine. The rest is often baking soda or some other adulterant. Crack addiction is hard to treat. The euphoric recall of the drug is intense and often people in recovery who’s primary drug of choice is Crack tend to have a lower chance of success in treatment. Crack cocaine releases a tremendous amount of dopamine quickly and then the level of dopamine drops suddenly, causing depression and an intense feeling of sadness. The extreme highs and lows of the drug is what often creates psychological addiction.
Meth Addiction
Methamphetamine or Meth is a cheap and highly addictive drug. There are often methamphetamine epidemics in towns across America as methamphetamine labs pop up and people begin to abuse the drug and then offer it to their friends, who then become addicted. There have been reports that the methamphetamine currently being produced in makeshift labs across the country is the most addictive drug there is. Methamphetamine produces a tremendous amount of energy coupled with euphoria. Methamphetamine addicts can stay awake for days and even weeks at a time. Methamphetamine often causes symptoms identical to Paranoid Schizophrenia after extended periods of use (Amphetamine induced psychosis). The symptoms often dissipate after drug use stops, but sometimes the symptoms persist for some time. The drug can be smoked, inhaled, ingested, or injected.

Meth and the Brain

- Meth releases a surge of dopamine, causing an intense rush of pleasure or prolonged sense of euphoria.
- Over time, meth destroys dopamine receptors, making it impossible to feel pleasure.
Although these pleasure centers can heal over time, research suggests that damage to users’ cognitive abilities may be permanent.
- Chronic abuse can lead to psychotic behavior, including paranoia, insomnia, anxiety, extreme aggression, delusions and hallucinations, and even death.
“There [are] a whole variety of reasons to try methamphetamine,” explains Dr. Richard Rawson, associate director of UCLA’s Integrated Substance Abuse Programs. “[H]owever, once they take the drug … their reasons are pretty much the same: They like how it affects their brain[s].” Meth users have described this feeling as a sudden rush of pleasure lasting for several minutes, followed by a euphoric high that lasts between six and 12 hours, and it is the result of drug causing the brain to release excessive amounts of the chemical dopamine, a neurotransmitter that controls pleasure. All drugs of abuse cause the release of dopamine, even alcohol and nicotine, explains Rawson, “[But] methamphetamine produces the mother of all dopamine releases.”
For example, in lab experiments done on animals, sex causes dopamine levels to jump from 100 to 200 units, and cocaine causes them to spike to 350 units. “[With] methamphetamine you get a release from the base level to about 1,250 units, something that’s about 12 times as much of a release of dopamine as you get from food and sex and other pleasurable activities,” Rawson says. “This really doesn’t occur from any normally rewarding activity. That’s one of the reasons why people, when they take methamphetamine, report having this euphoric [feeling] that’s unlike anything they’ve ever experienced.” Then, when the drug wears off, users experience profound depression and feel the need to keep taking the drug to avoid the crash.
When addicts use meth over and over again, the drug actually changes their brain chemistry, destroying the wiring in the brain’s pleasure centers and making it increasingly impossible to experience any pleasure at all. Although studies have shown that these tissues can regrow over time, the process can take years, and the repair may never be complete. A paper published by Dr. Nora Volkow, director of the National Institute on Drug Abuse, examines brain scans of several meth abusers who, after 14 months of abstinence from the drug, have regrown most of their damaged dopamine receptors; however, they showed no improvement in the cognitive abilities damaged by the drug. After more than a year’s sobriety, these former meth users still showed severe impairment in memory, judgment and motor coordination, similar to symptoms seen in individuals suffering from Parkinson’s Disease.
In addition to affecting cognitive abilities, these changes in brain chemistry can lead to disturbing, even violent behavior. Meth, like all stimulants, causes the brain to release high doses of adrenaline, the body’s “fight or flight” mechanism, inducing anxiety, wakefulness and intensely focused attention, called “tweaking.” When users are tweaking, they exhibit hyperactive and obsessive behavior, as journalist Thea Singer’s sister Candy did on her meth binges. “When she was high, which was almost always, she had to be on the computer — diddling with programs to make them run faster, ordering freebies on the Internet,” writes Singer. “Then computers faded, and she was obsessed with diving into dumpsters — rescuing audio equipment from behind Radio Shack, pens from behind Office Depot.” Heavy, chronic usage can also prompt psychotic behavior, such as paranoia, aggression, hallucinations and delusions. Some users have been known to feel insects crawling beneath their skin. “He picks and picks and picks at himself, like there are bugs inside his face,” the mother of one meth addict told Newsweek . “He tears his clothes off and ties them around his head.” The same article told the story of another former addict, who, even after five years of sobriety, can’t go to the bathroom without propping a space heater against the door, in case someone is after him.
