Cocaine Addiction

Cocaine is a highly addictive stimulant that mainly affects the brain. Pure cocaine was first extracted from the leaf of the Erythroxylon coca bush, which grows mainly in Peru and Bolivia. Today, cocaine is a Schedule II drug, meaning it can be administered by a doctor for medical uses, such as a local anesthetic. There are two basic forms of cocaine, hydrochloride salt and the "freebase." The hydrochloride salt form of cocaine dissolves in water and can be taken by vein or in the nose. The "freebase" form of cocaine is smokable.

In 1997, an estimated 1.5 million Americans were cocaine users. This number has not changed since 1992, even though it is a large decrease from 5.7 million cocaine users in 1985. Adults 18 to 25 years of age have a much higher rate of cocaine use than any other age group. The main routes of cocaine administration are oral, intranasal, intravenous, and inhalation. More common words used for administration are chewing,

snorting, mainlining, injecting, and smoking. Cocaine use ranges from occasional use to repeated use, with a wide range of patterns. Any route of administration can lead to absorption of toxic amounts of cocaine. Repeated cocaine use can produce addiction and other adverse health problems.

Cocaine's effects appear almost immediately and disappear within a few minutes or hours. The duration of the effects depends upon the route of administration. The short-term effects include constricted blood vessels, dilated pupils, and increased temperature, heart rate, and blood pressure. Cocaine is a powerfully addictive drug.

Once having tried cocaine an individual may have difficulty predicting or controlling the extent to which a person will continue to use the drug. A user can build up a high tolerance to cocaine's high. Some users will increase their dose to intensify and prolong

the effects. Users can also become more sensitive to cocaine's effects, which may explain some deaths occurring after apparent low doses.

There are many medical complications associated with cocaine use.

    In Less Than Zero, cocaine addiction tests a group of three friends against the backdrop of glamorous, 1980’s Los Angeles. I chose this film because I’ve read the novel by Bret Easton Ellis. While the movie differs quite a bit from the book, it still touches on some key points about drug use that Ellis speaks to in the novel. At the beginning of the film, Clay, Julian, and Blair have graduated high school in Beverly Hills. Clay chooses to leave and attend a prestigious university. Blair (Clay’s girlfriend) stays in Los Angeles because she is too afraid to go to school. Julian’s father gives him a large sum of money to start his own recording studio. By Thanksgiving, Clay returns to Los Angeles to find Julian and Blair sleeping together. At

    This system operates through the release of various neurochemical transmitters (from the nerve cells in which they are produced) and their binding to receptor sites on neighboring cells. The constant release and binding of these neurotransmitters forms a pathway of “messages” that travel throughout the body, sustaining life and making possible the organism’s response to environmental stimuli. The drug also has an impact in the autonomic (or involuntary) division of the central nervous system, which helps regulate a variety of bodily functions that are generally free of volitional impact, including respiration, circulation, digestion, and body temperature. Ordinarily, these functions are maintained at relatively stable levels throughout the day. But they are slowed down during periods of rest through diminished production, release, and binding of neurotransmitters and can be speeded up, as needed, through increased neurotransmitter activity. It operates in the system by increasing the concentration and binding activity of the body’s own neurotransmitters, particularly dopamine. Thus, what people experience as the stimulant effect is an intensification of the body’s normal stimulatory mechanisms. (Pharmacodynamics: Cocaines Interaction with the Human Organism,

Many people avoided the use of crack because of the harmful chemicals used in creating the drug. One of the reasons why crack became popular is because of not needing to inject the drug hence less risks of being infected by the AIDS virus. Carroll (2000) states cocaine is the most powerful stimulant of natural origin. Most users snort or inject the drug to enable a quicker “high.” Cocaine use brings on many health problems. Fatal complications occur from regular use, for example, liver damage, seizures, elevated blood pressure causing stroke, heart failure, or heart attack.

    Substance use disorders and mental health disorder can be challenging for human services professionals as well as for the individual; combined these disorders together and treatment can be seemingly insurmountable. The complexity of the disorders separately, as well as together raises the need for treatment that looks at the whole person not just a set of symptoms. The debate between which disorder came first is useless at helping to resolve the problems that are currently occurring with these complex disorders. According to Stevens & Smith (2013), over five million adults have a co-occurring disorder. With such high number it’s no surprise that the amount of money that is spending on co-occurring disorders is staggering and far exceeds that
