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).

Crack works on the automatic nervous system. The automatic nervous system controls the sympathetic system which speeds everything up such as heart rate and breathing. The autonomic nervous system also controls the para-sympathetic system which does the exact opposite (slows things down). This explains why people become hyper when the smoke crack.

Addicts are preoccupied with getting their drug, and most of their thoughts and behaviors are directed to that end. Cocaine interferes with judgment and produces exaggerated feelings of well-being and confidence. High doses can produce paranoia, and users can become aggressive and violent. In rare cases, cocaine can produce death, after first use or after prolonged use.

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 Americans, 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 in the United States.

Cocaine's effects appear almost immediately after a single dose, and disappear within a few minutes or hours. Taken in small amounts (25 to 150 mg), cocaine usually makes the user feel euphoric, energetic, talkative, and mentally alert, especially to the sensations of sight, sound, and touch. It can also temporarily decrease the need for food and sleep.

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 reabsorption 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 amount of electricity produced by the Acuscope is measured in microamps (millionths of an amp), an extremely tiny amount of current in comparison to the amount of electricity flowing from a wall socket. It has been scientifically proven that this level of current produces the most beneficial effect on the body's cells.

Just clean air. The Austin Air Cleaner does NOT produce OZONE, IONS, or NEGATIVE IONS. Ozone is active Oxygen and can be dangerous to people with respiratory problems, such as asthma and emphysema. Periodic vacumming of the four sides on the outside screen is the only maintenance required for the Austin Air Cleaner. Typically, the filter only needs to be changed every five years.

It produces XHTML compatible with the XHTML 1.0 specification. A cascading stylesheet is required for proper viewing with a modern graphical browser. Correct rendering of the HTML produced depends on the CSS support of the browser. A general-purpose stylesheet, html4css1.css is provided with the code, and is embedded by default. It is installed in the "writers/html4css1/" subdirectory within the Docutils package.

Although both cocaine and methamphetamine are psychostimulants that trigger the release of dopamine, the drugs are quite different. For one thing, methamphetamine produces a stronger and longer-lasting high than the high produced by cocaine. Animal studies conducted at UCLA show that cocaine releases 350 units of dopamine, while methamphetamine releases almost four times as much -- about 1,200 units (See a slideshow on the neuroscience of meth).

The U.S./Mexico border is the primary point of entry for cocaine shipments being smuggled into the United States. According to a recent interagency intelligence assessment, approximately 65 percent of the cocaine smuggled into the United States crosses the Southwest border. Cocaine is readily available in nearly all major cities in the United States. Organized crime groups operating in Colombia control the worldwide supply of cocaine.

Through the use of sophisticated technology, scientists can actually see the dynamic changes that occur in the brain as an individual takes cocaine. They can observe the different brain changes that occur as a person experiences the "rush," the "high," and finally the craving of cocaine. They can also identify parts of the brain that become active when a cocaine addict sees or hears environmental stimuli that trigger the craving for cocaine.

In order to answer this question we first need to review how our body builds muscles. The key to building muscle mass is protein metabolism (to learn more about protein click here). Interestingly, our body does not make muscles while we workout, it is during the recovery time after we workout that muscles are made. Our body goes through a constant cycle of catabolism and anabolism.

Acute or chronic stresses, whether minor or major, register in your mind as danger. Your body gears up to help you "fight" or "flee" the situation at hand. Blood sugar, fatty acids, adrenaline and other stimulating chemicals and hormones enter your blood stream to increase brain and body arousal. In turn, your immune and digestive system shut down to support this process. Evolutionarily, the fight or flight response was meant to be swift and decisive.

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 aluminum foil, plastic or paper packets, or small vials.
