iHealthBuzz - You have certainly heard a lot about the dangers posed by drug abuse.

Manipulate feelings, moods, and behavior

Because drugs affect the work of the brain, drugs can change the mood of feelings, ways of thinking, awareness and behavior of the wearer. That is why narcotics are called psychoactive substances. There are several kinds of effects of drugs on the brain, such as inhibiting the work of the brain, called depression, this will reduce awareness resulting in drowsiness. Examples are opioids such as opium, morphine, heroin, petidine), sedatives (sedativa and hypnotics) such as BK, Lexo, Rohyp, MG and alcohol pills.

Drugs affect the part of the brain responsible for the "life" feeling, which is called the limbus system. The hypothalamus as a pleasure center in the brain is part of the limbus system.

Spur excessive brain work

Drugs can also stimulate the work of the brain or what is often called a stimulant, so that arises a sense of freshness and enthusiasm, increased confidence, and relationships with other people become close. However, this can cause you to be unable to sleep, restlessness, faster heart palpitations and increased blood pressure. Examples are amphetamine, ecstasy, crystal meth, cocaine, and nicotine found in tobacco.

Trigger hallucinations

There are also drugs that cause delusions, or what are often called hallucinogens. An example is LSD. In addition to LSD, there are cannabis that cause various influences, such as changing perceptions of time and space, as well as increasing imagination, so that cannabis can be classified as hallucinogenic.

In brain cells there are various chemicals called neurotransmitters. These chemicals work at the connection of one nerve cell with other nerve cells (synapses). Some neurotransmitters are similar to several types of drugs.

All psychoactive substances (narcotics, psychotropic substances and other addictive substances) can change a person's behavior, feelings and thoughts through their effects on one or several neurotransmitters. The neurotransmitter that plays the most role in dependence is dopamine.

Effects of drugs on the nervous system

Narcotics abuse has an influence on the work of the nervous system. Anything? The following explanation.

Sensory nerve disorders. This disorder causes numbness and blurred vision that can cause blindness.
Autonomic nervous disorders. This disturbance causes unwanted movements through motor motion. So that people who are drunk can do anything outside of their consciousness. For example when drunk, these users can disturb people, fight and so on.

Motor nerve disorders. This movement without coordination with the motor system. For example like another person 'on', his head can shake itself, the new movement stops if the influence of the narcotics is gone.

Vegetative nerve disorders. This is related to language that comes out of consciousness. Not only that, the effects of drugs on the brain can cause fear and lack of confidence if you do not use it.
In the long run, drugs can slowly damage the nervous system in the brain from mild to permanent. When using narcotics, excessive electrical charge in the brain, if you are addicted, then over time the nerves can be damaged. Do you want to be blind, distracted, or intentionally incarcerated for drugs?

How can drug users become addicted?

Then, what happens to someone who is addicted? Addiction is a kind of 'learning' of brain cells at the center of enjoyment. When you try to take drugs, the brain will read your body's response. If you feel comfortable, the brain secretes the neurotransmitter dopamine and will give a pleasant impression.

The brain records it as something that is sought as a priority because it is considered fun. As a result, the brain makes a wrong program, as if the person needs it as a basic need and addiction or dependence occurs. In a state of dependency, addicts feel very uncomfortable and in pain. To get drugs, he will do everything possible like stealing, even killing.

In the case of dependency, a person must always use drugs, otherwise symptoms of drug withdrawal (or also called sakau) arise, if the use is stopped or the amount is reduced. Symptoms depend on the type of drug used.

Symptoms of sakio opioida (heroin) are similar to those with severe cold, namely runny nose, tears coming out, standing body hair, muscle aches, nausea, vomiting, diarrhea, and difficulty sleeping. Drugs also disrupt the function of other body organs, such as the heart, lungs, liver and reproductive system, so that various diseases can arise.

Drug users will continue to increase their dosage until overdose

So, the feeling of pleasure, comfort, calm or joy that is sought by drug users, must be paid handsomely by its bad effects, such as dependence, damage to various organs, various diseases, damage to relationships with family and friends, damage to moral life, school dropouts , unemployment, and the destruction of his future.

Consuming drugs continuously causes an increase in body tolerance so that the user cannot control their use and tends to continue to increase the dose of use until finally the body can no longer accept. This is called overdose.

Nerves are one of the important organs in humans that regulate body systems. If he is damaged it can cause permanent disability and is difficult to repair. You do not want it, disability only because of drugs?
