Some drugs, such as marijuana and heroin, have a similar structure to chemical messengers, called neurotransmitters, which are naturally produced by the brain. Because of this similarity, these drugs are able to “fool” the brain’s receptors and activate nerve cells to send abnormal messages.

Other drugs, such as cocaine or methamphetamine, can cause the nerve cells to release abnormally large amounts of natural neurotransmitters, or prevent the normal recycling of these brain chemicals, which is needed to shut off the signal between neurons. This disruption produces a greatly amplified message that ultimately disrupts normal communication patterns.

Nearly all drugs, directly or indirectly, target the brain’s reward system by flooding the circuit with dopamine. Dopamine is a neurotransmitter present in regions of the brain that control movement, emotion, motivation, and feelings of pleasure. The overstimulation of this system, which normally responds to natural behaviors that are linked to survival (eating, spending time with loved ones, etc.), produces euphoric effects in response to the drugs. This reaction sets in motion a pattern that “teaches” people to repeat the behavior of abusing drugs.

As a person continues to abuse drugs, the brain adapts to the overwhelming surges in dopamine by producing less dopamine or by reducing the number of dopamine receptors in the reward circuit. As a result, dopamine’s impact on the reward circuit is lessened, reducing the abuser’s ability to enjoy the drugs and the things that previously brought pleasure. This decrease compels those addicted to drugs to keep abusing drugs in order to attempt to bring their dopamine function back to normal. And, they may now require larger amounts of the drug than they first did to achieve the dopamine high—an effect known as tolerance.

Long-term abuse causes changes in other brain chemical systems and circuits as well. Glutamate is a neurotransmitter that influences the reward circuit and the ability to learn. When the optimal concentration of glutamate is altered by drug abuse, the brain attempts to compensate, which can impair cognitive function. Drugs of abuse facilitate nonconscious (conditioned) learning, which leads the user to experience uncontrollable cravings when they see a place or person they associate with the drug experience, even when the drug itself is not available. Brain imaging studies of drug-addicted individuals show changes in areas of the brain that are critical to judgment, decisionmaking, learning and memory, and behavior control. Together, these changes can drive an abuser to seek out and take drugs compulsively despite adverse consequences—in other words, to become addicted to drugs.

Treatments for Drug addiction vary on many factors including the severity and duration of symptoms, the amount of damage caused by cocaine, and recovery. The most common symptoms of addiction are generally noted the desire for drugs, irritability, loss of energy, depression, anxiety, tremors want too much or insomnia, nausea and palpitations, sweating, hyperventilation, increased appetite and sleep. These symptoms can usually take several weeks – even after cessation of cocaine.

Drugs for treating cocaine addiction are not yet available, although researchers are working feverishly to identify and test new features. The drug appears to be promising experimental selegiline force still needs an appropriate method of administration. Disulfiram, a drug used to treat alcoholism, has proved to be somewhat “effective in the treatment of cocaine abuse during clinical trials. Antidepressants are prescribed primarily to treat mood swings, usually cocaine withdrawal. Treatments have been developed to deal with an overdose of cocaine.

Edits, such as cognitive behavioral skills to adapt to be effective in treating cocaine addiction, but there are only a short-term approach that focuses on the learning process. Behavioral therapy to help patients recognize, prevent and treat conditions that lead to use cocaine again.

This treatment is dedicated doctors, nurses and therapists, treatment programs to recognize the severity of addiction. On the basis that treatment programs provide well-documented medical techniques, the best choice for patients of all types of treatment available.

heroin binds to the neurotransmitter receptor and directly stimulates Refugio channels, nicotine and alcohol trigger a complex “chemical cascade which raises dopamine levels and there is also an unknown chemical in cigarettes that increases dopamine levels by blocking the enzyme MAO B.

Dopamine, as I mentioned, is more than one molecule of pleasure, also plays a special role in relation to learning and memory.

The extent to which learning and memory hold, so to speak, the addictive process is being studied. Each time a neurotransmitter such as dopamine reaches a synapse, circuits that trigger thoughts and motivation to action are fired and scattered throughout the brain. Furthermore, the neurotransmitter that keeps the addiction is so powerful that people, objects, situations and places where drugs are consumed in the memory. It has also shown that stimulated by the smell of snuff for smokers can not control the urge to light a cigarette and Pavlov’s dogs could not stop salivating.

The brain has several ways to ensure that the irrational act of taking drugs, which cause pleasure in being involved dopamine, will be repaired. PET images show that the absorption of cocaine by neurons is markedly reduced in the drug addicts in contrast with normal subjects. One possible explanation is the following: the neurons of addicts, “assaulted” by an abnormally high amount of dopamine and respond defensively and reduce the number of dopamine receptors. In the absence of drug experiments, these neurons probably a shortage of dopamine, which explains why addicts start taking drugs to feel better and then have to consume to avoid feeling caimiento and discomfort, as well as why an increasing need for substance to achieve the same effect.

The common mechanism of action is what really is a track called the path of the mesolimbic reward, which is a neurotransmitter is dopamine. All addictive drugs that stimulate the brain reward circuit d.

This circuit activates a region of the limbic system is what regulates emotion and behavior and is what gives us the perception of pleasure. When neurons release certain neurotransmitters, and these circuits are activated when we feel good. However, the drugs can alter the mechanism of reward.

What do these drugs is to teach your customer to take them again and again. It’s like a reward system booster.

Prolonged use of a substance can alter these brain systems as the brain require the presence of exogenous substances to maintain their homeotasis. Initially, the consumption of opiates increase dopamine levels, but eventually you need the addition of more substance to achieve the same effect of euphoria or pleasure.

Have published several studies showing that the greater the activation of the dopamine system, the greater the experience of euphoria. Therefore, it is known that dopamine is the critical element and that all addictive substances alter dopamine levels in this part of the brain.

The idea that everything can be related to a single chemical has a keen interest to scientists and has changed the way you watch a wide range of sponsors. Dopamine is not only a chemical that transmits pleasure signals but is also the most important molecule involved in addiction.

This does not mean that dopamine is the only chemical that determines the chronic drug abuse, we know that the brain is much more complex. Drugs modulate a wide variety of brain chemicals each of which interacts with others.

The hypothesi of dopamine provides a framework for understanding a genetic code (such as the tendency to produce little dopamine for example) can interact with the environment and create serious dysfunction in behavior.

Cocaine is a drug that makes you confident, talkative, alert, good draw for those who find it difficult, in this way is usually the feeling. However, because the drug decreases, rapidly associated with depression, anxiety and irritability with the of version.

Not immediately hooked. Some people may take the same amount over a long period and not become dependent. The availability, lifestyle and personality are all factors. However, how can a cigarette from time to time, sometimes “-benign” use of recreational cocaine in normal light, sliding nasty long-term abuse.
In the worst cases can kill the cocaine psychosis – a condition not very nice to anxiety, insomnia, paranoia, anxiety, mood swings, lack of sexual appetite and weight loss.

Some organizations, existing drugs fight against cocaine psychosis as the inevitable consequence of occasional use. It is not. It should work, but it is easy to see how much you get.
Profile care centers, centers of local treatment are now learning more
but here is some good news: stop the coke, if you can, and will become normal.
