Drugs Affecting the Brain Work
Posted on 5:06 AM by publisher
One result of narcotics is affecting the brain works. Drug influenced the workings of the brain that serves as a central control body and affect the whole body functions. Since work on the brain, drugs change the mood a feeling, a way of thinking, consciousness and behavior of its users. That is why drugs called psychoactive substances.
According to Agent Daniel Lawrence, SKM, Lecturer Nursing Darma Insan Pontianak, there are several kinds of drug effects on brain works. There's inhibiting the brain works, called depresansia, thus decreasing consciousness and drowsiness occur. Examples of this type is that the community opioida clouds known as opium, morphine, heroin and petidin. Then tranquilizers or sleeping pills (sedativa and hipnotika) such as the pill BK, Lexo, Rohyp, MG and others, as well as alcohol.
But there are drugs that stimulate the brain, called stimulansia, which raised the fresh taste and passion, confidence increased, relations with others become familiar. But the cause could not sleep, anxiety, heart beat faster and blood pressure increase. Examples are amphetamines, ecstasy, shabu, cocaine, and nicotine contained in tobacco. There is also a drug that causes delusion, called halusinogenika. Examples of LSD. Marijuana cause various effects, such as changing the perception of time and space, and increased imagination, so that marijuana can be classified as halusinogenika.
The agent said, the brain cells have a variety of chemicals called neurotransmitters. These chemicals work on the connection of one nerve cell to other nerve cells (synapses). Some of the neurotransmitter that is similar to several types of drugs. All psychoactive substances (narcotics, psychotropic and other addictive substances) can change the behavior, feelings and thoughts affect a person through one or more neurotransmitters. Neurotransmitter most responsible for the occurrence of dependence is dopamine.
Part of the brain responsible for feelings of life is the limbus system. The hypothalamus is the part of the limbus, as the pleasure center. If the drug enters the body, by way of ingested, inhaled, or injected, the drugs change the order of biochemical neurotransmitters limbus system. Because there are drug intake from the outside, the body's production halted or interrupted, so he will always need drugs from outside.
"What happened to learning the dependency is a kind of brain cells in the pleasure center. If taking drugs, the brain responses of people read it. If you feel comfortable, remove the brain neurotransmitter dopamine, and will provide good impression. If you do drugs again, people feel good again as if his inner needs satisfied. The brain will record it as something to be sought as a priority for the fun. As a result, the brain makes the wrong program, as if someone was needed as a staple. Occurs addiction or dependence, "he said.
In dependence, one should always take drugs, if not, a substance withdrawal symptoms occur if use is stopped or reduced in number. The symptoms depend on type of drug used. Opioida withdrawal symptoms (heroin) is similar to the severe cold, ie runny nose, the tears, hairs standing body, muscle aches, nausea, vomiting, diarrhea, and insomnia.
Drugs also interfere with the function of organs, such as heart, lungs, liver and reproductive system, which can arise various diseases. Example: opioida cause constipation, menstrual disorders, and impotence. If you use needles at risk of contracting viral hepatitis B / C (inflammation of the liver disease). Also at risk of contracting HIV / AIDS which lowers immunity, so prone to infection, and can cause death. Marijuana causes loss of interest, disturbed memory, mental disorders, confusion, depression, and declining fertility. While cocaine may cause nasal septum bone thinning or holes, memory loss, mental disturbances, increased heart work and heart attacks.
Thus, feelings of pleasure, comfort, quiet or excitement that initially sought by drug users, very expensive to be paid by the bad effects. Like dependence, damage to various organs of the body, various diseases, broken relationships with family and friends, undermining even the financial bankruptcy, the destruction of the moral life, dropout, unemployment, and the destruction of the future itself.
Another result he was threatened by sexual dysfunction. In this case resulted in drug addiction that is difficult to overcome because of the withdrawal syndrome
known as "sakauw". These days more and more widespread abuse in the community, both young and old. Many reasons stated. From a lifestyle, persuaded other people to depend and then penjadi regulars, as an escape from problems, and recently popular notion of drugs can improve sexual function. This assumption was not proven, otherwise may damage sexual function and other body organs.
There are several drug groups; narcotics (opiates, opium), halusinogenik (hashish or marijuana), stimulants (ecstasy, shabu-shabu), depressants (sedatives). Each has its own effects on its users.
Opiates that produce heroin or putauw make users feel like flying, good or great happy (euphoria). Hashish or marijuana (halusinogenik group) resulted in the emergence of hallucinations, as users seem happy dream. 40 to 60% users reported side effects such as unpleasant vomiting, headaches, tremors, muscles may feel weak, confused, anxious, wanting to kill themselves and others. While the stimulant substances (ecstasy, shabu-shabu), a substance contained in it stimulates the central nervous system and cause physical and psychological stimulation. Ecstasy users high-spirited, always happy, want to move on, to not want to sleep and eat.
Drug abuse lead to physical and psychological disorders. All depends on what type of drugs used, how the use and duration of use. The disturbance that took place between other brain damage, liver disorders, kidney, stomach, lung / respiratory, cardiovascular, HIV / AIDS through needles used interchangeably, muscle paralysis, neurological disorders, pregnancy, hormonal disorders, and cancer .
While psychological disturbance is; attitude of apathy, euphoria, emotional instability, depression, suspicion is groundless, losing control of behavior to experience mental illness. Due to physical and psychic is less social contact with other people, harm others, eg, fights, traffic accidents.
Drugs, said the agent, also interfere with sexual function of reproduction. Heroin, although the cause euphoria, but a bad influence for sexual function. In the male could lower testosterone levels, decreased sex drive, erectile dysfunction and ejaculation barriers. In women decreased sex drive, failure of orgasm, inhibition of menstruation, fertility disorders, smaller breasts and her discharge from the breast.
Meanwhile, in addition to causing hallucinations Marijuana is bad also for men sexual. The effect, can make the size of the testes or testicles shrinking. The decline in testosterone levels, male breast enlargement, decreased sex drive, erectile dysfunction, disturbances in sperm. While the women bias resulting interference with the egg cell, the resistance became pregnant / delivery delays, decreased sexual drive.
Ecstasy alone his stimulant properties make users keep high-spirited, excited, wanted to move on. Although stimulating impact, but does not provoke a positive effect on sexual function. Ecstasy increases the release of the neurotransmitter dopamine in the brain, which then stimulates sexual behavior and may result in loss of ability to control sexual behavior. Users so brave to have sex without thinking about the risks that may occur.
While depressants or sedatives can also cause bad effect on sexual function. The use of barbiturates causing disruption of testosterone and estrogen metabolism
. In the men can reduce sexual drive and erectile dysfunction. In the female lead to menstrual disorders, decreased sex drive and difficulty reaching orgasm.
