Cocaine Addiction Symptoms

What is the History of Cocaine?
Cocaine is derived from the leaves of the coca bush, which grows in South America. Cocaine has been used for centuries by Indians to combat the effects of hunger, hard work, and thin air. In the mid 1800s its effects were praised by Freud, among others. Until 1906, this substance was a chief ingredient of Coca-Cola and was also used as a anaesthetic. Widespread use and addiction led to government efforts against cocaine in the early 1900s. The danger associated with cocaine was ignored in the 1970s and early 1980s, and cocaine was proclaimed by many to be safe. With the accumulating medical evidence of cocaine's deleterious effects and the introduction and widespread use of cocaine, the public and government have become alarmed again about its growing use.

What is Cocaine?
Cocaine, the most potent stimulant of natural origin, is extracted from the leaves of the coca plant (Erythroxylon coca), which is indigenous to the Andean highlands of South America. It is a potent brain stimulant and one of the most powerfully addictive drugs. Cocaine is produced as a white chunky powder. It is sold most often in aluminium foil, plastic or paper packets, or small vials. Cocaine is usually chopped into a fine powder with a razor blade on a small mirror or some other hard surface, arranged into small rows called "lines," then quickly inhaled (or "snorted") through the nose with a short straw or rolled up paper money. It can also be injected into the blood stream.

How is cocaine used?
There are four primary methods of ingesting cocaine. These are:
"Snorting" - absorbing cocaine through the mucous membranes of the nose.
Injecting - users mix cocaine powder with water and use a syringe to inject the solution intravenously.
Freebasing - Cocaine hydrochloride is converted to a "freebase" which can then be smoked.
Crack Cocaine - Cocaine hydrochloride is mixed with ammonia or sodium bicarbonate (baking soda) and other ingredients, causing it to solidify into pellets or "rocks". The crack is then smoked in glass pipes.

What are the symptoms of Cocaine use?
The symptoms of Cocaine use include but are not limited to:
-anxiety
-panic
-bloody nose
-increased energy
-talking rapidly
-rapid pulse and respiration paranoia
-confusion
-dilated pupils
-hallucinations
-altered motor activities (tremors, hyperactivity)
-stuffiness
-runny nose

What is Cocaine addiction?
Cocaine addiction can occur very quickly and can be very difficult to break. Animal studies have shown that animals will work very hard (press a bar over 10,000 times) for a single injection of cocaine, choose cocaine over food and water, and take cocaine even when this behaviour is punished. Animals must have their access to cocaine limited in order to prevent taking toxic or even lethal doses.
Researchers have found that cocaine stimulates the brain's reward system inducing an even greater feeling of pleasure than natural functions. In turn, its influence on the reward circuit can lead a user to bypass survival activities and repeat drug use. Chronic cocaine use can lead to a cocaine addiction and in some cases damage the brain and other organs. An addict will continue to use cocaine even when faced with adverse consequences. Dependency can develop in less than 2 weeks. Some research indicates that a psychological dependency may develop after a single dose of high-potency cocaine. As the person develops a tolerance to cocaine, higher and higher doses are needed to produce the same level of euphoria.

How Does Cocaine Affect the Brain?
Cocaine is a strong central nervous system stimulant that increases levels of dopamine, a brain chemical associated with pleasure and movement, in the brain’s reward circuit. Certain brain cells, or neurons, use dopamine to communicate. Normally, dopamine is released by a neuron in response to a pleasurable signal (e.g., the smell of good food), and then recycled back into the cell that released it, shutting off the signal between neurons. Cocaine acts by preventing the dopamine from being recycled, causing excessive amounts of dopamine to build up, amplifying the message, and

ultimately disrupting normal communication. It is this excess of dopamine that is responsible for cocaine euphoric effects.

With repeated use, cocaine can cause long-term changes in the brain reward system and in other brain systems as well, which may eventually lead to addiction. With repeated use, tolerance to the cocaine high also often develops. Many cocaine abusers report that they seek but fail to achieve as much pleasure as they did from their first exposure. Some users will increase their dose in an attempt to intensify and prolong the euphoria, but this can also increase the risk of adverse psychological or physiological effects.

Why would anyone become addicted to Cocaine?
The effects of cocaine are immediate, extremely pleasurable, and brief. Cocaine produce intense but short-lived euphoria and can make users feel more energetic. Like caffeine, cocaine produces wakefulness and reduces hunger. Psychological effects include feelings of well-being and a grandiose sense of power and ability mixed with anxiety and restlessness. As the drug wears off, these temporary sensations of mastery are replaced by an intense depression. The drug abuser will then "crash", becoming lethargic and typically sleeping for several days.

How does cocaine produce its effects?

A great amount of research has been devoted to understanding the way cocaine produces its pleasurable effects, and the reasons it is so addictive. One mechanism is through its effects on structures deep in the brain. Scientists have discovered regions within the brain that, when stimulated, produce feelings of pleasure. One neural system that appears to be most affected by cocaine originates in a region, located deep within the brain, called the ventral tegmental area (VTA). Nerve cells originating in the VTA extend to the region of the brain known as the nucleus accumbens, one of the brain's key pleasure centres. In studies using animals, all types of pleasurable stimuli, such as food, water, sex, and many drugs of abuse, cause increased activity in the nucleus accumbens.Researchers have discovered that, when a pleasurable event is occurring, it is accompanied by a large increase in the amounts of dopamine released in the nucleus accumbens by neurons originating in the VTA. In the normal communication process, dopamine is released by a neuron into the synapse (the small gap between two neurons), where it binds with specialised proteins (called dopamine receptors) on the neighbouring neuron, thereby sending a signal to that neuron. Drugs of abuse are able to interfere with this normal communication process. For example, scientists have discovered that cocaine blocks the removal of dopamine from the synapse, resulting in an accumulation of dopamine. This build up of dopamine causes continuous stimulation of receiving neurons, probably resulting in the euphoria commonly reported by cocaine abusers.

As cocaine abuse continues, tolerance often develops. This means that higher doses and more frequent use of cocaine are required for the brain to register the same level of pleasure experienced during initial use. Recent studies have shown that during periods of abstinence from cocaine use, the memory of the euphoria associated with cocaine use or mere exposure to cues associated with drug use, can trigger tremendous craving and relapse to drug use even after long periods of abstinence.

What are the physical effects of cocaine addiction?

With the accumulating medical evidence of cocaine's deleterious effects and the introduction and widespread use of cocaine, the public and government have become alarmed again about its growing use. To many, especially health care and social workers who deal with cocaine users and have witnessed the personal and societal devastation it produces, cocaine addiction is by far the most serious drug problem.

Cocaine use increases the risk of sudden heart attack and may also trigger stroke, even in users who otherwise are not at high risk for these sometimes fatal cardiovascular events. The risk is related to narrowing of blood vessels and increases in blood pressure and heart rate. Recently, NIDA-supported researchers at the Alcohol and Drug Abuse Research Centre at McLean Hospital in Belmont, Massachusetts, have identified changes in blood components that may also play a role in cocaine-related heart attack and stroke.

The physical effects of cocaine addiction include but are not limited to:

-Changes in blood pressure, heart rates, and breathing rates

-Nausea

-Vomiting

-Anxiety

-Convulsions

-Insomnia

-Loss of appetite leading to malnutrition and weight loss

-Cold sweats

-Swelling and bleeding of mucous membranes

-Restlessness and anxiety

-Damage to nasal cavities

-Damage to lungs

-Possible heart attacks, strokes, or convulsions

What are the long term effects of cocaine?

Cocaine is a powerfully addictive drug. Once having tried cocaine, an individual may have difficulty predicting or controlling the extent to which he or she will continue to use the drug. Cocaine's stimulant and addictive effects are thought to be primarily a result of its ability to inhibit the re-absorption of dopamine by nerve cells. Dopamine is released as part of the brain's reward system, and is either directly or indirectly involved in the addictive properties of every major drug of abuse.

The long-term effects of cocaine include but are not limited to:

-Irritability

-Mood disturbances

-Restlessness

-Paranoia

-Auditory hallucinations

-Addiction

An appreciable tolerance to cocaine's high may develop, with many addicts reporting that they seek but fail to achieve as much pleasure as they did from their first experience. Some users will frequently increase their doses to intensify and prolong the euphoric effects. While tolerance to the high can occur, users can also become more sensitive (sensitization) to cocaine's anaesthetic and convulsant effects, without increasing the dose taken. This increased sensitivity may explain some deaths occurring after apparently low doses of cocaine.

Use of cocaine in a binge, during which the drug is taken repeatedly and at increasingly high doses, leads to a state of increasing irritability, restlessness, and paranoia. This may result in a full-blown paranoid psychosis, in which the individual loses touch with reality and experiences auditory hallucinations.

What Adverse Effects Does Cocaine Have on Health?

Abusing cocaine has a variety of adverse effects on the body. For example, cocaine constricts blood vessels, dilates pupils, and increases body temperature, heart rate, and blood pressure. It can also cause headaches and gastrointestinal complications such as abdominal pain and nausea. Because cocaine tends to decrease appetite, chronic users can become malnourished as well.

Different methods of taking cocaine can produce different adverse effects. Regularly snorting cocaine, for example, can lead to loss of the sense of smell, nosebleeds, problems with swallowing, hoarseness, and a chronically runny nose. Ingesting cocaine can cause severe bowel gangrene as a result of reduced blood flow. Injecting cocaine can bring about severe allergic reactions and increased risk for contracting HIV and other blood-borne diseases. Binge patterns of use may lead to irritability, restlessness, anxiety, and paranoia. Cocaine abusers can suffer a temporary state of full-blown paranoid psychosis, in which they lose touch with reality and experience auditory hallucinations.

Regardless of how or how frequently cocaine is used, a user can experience acute cardiovascular or cerebrovascular emergencies, such as a heart attack or stroke, which may cause sudden death. Cocaine-related deaths are often a result of cardiac arrest or seizure followed by respiratory arrest.

Added Danger: Cocaethylene

When people consume cocaine and alcohol together, they compound the danger each drug poses and unknowingly perform a complex chemical experiment within their bodies. Researchers have found that the human liver combines cocaine and alcohol to produce a third substance, cocaethylene, which intensifies cocaine euphoric effects. Cocaethylene is associated with a greater risk of sudden death than cocaine alone.

What Treatment Options Exist?

Behavioral interventions particularly, cognitive-behavioral therapy have been shown to be effective for decreasing cocaine use and preventing relapse. Treatment must be tailored to the individual patient needs in order to optimize outcomesthis often involves a combination of treatment, social supports, and other services.

Currently, there are no medications for treating cocaine addiction. Researchers are looking for medications that help alleviate the severe craving experienced by people in treatment for cocaine addiction, as well as medications to counteract other triggers of relapse, such as stress. Several compounds are currently being investigated for their safety and efficacy, including a vaccine that would sequester cocaine in the bloodstream and prevent it from reaching the brain. Research so far suggests that addiction medications are most effective when used as a part of a comprehensive treatment program.
