Effects of drugs on the brain: from blindness to nerve damage: function, dosage, side effects, how to use

Of course, you have heard a lot about the dangers of drug abuse. Of the many effects, did you know that the use of narcotics, psychotropic substances and other addictive substances can affect the work of the brain, which functions as the body's control center? As a result this will affect all functions of your body. So, what are the effects of drugs on the brain?

The effects of drugs on the brain that you must be aware of

Manipulating feelings, moods and behavior

Because drugs affect the work of the brain, drugs can change the mood, feelings, ways of thinking, awareness and behavior of the user. 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, which is called depressants, this will reduce consciousness, resulting in drowsiness. Examples are opioids such as opioids, morphine, heroin, pethidine), sedatives (sedatives and hypnosis) such as BK pills, Lexo, Rohyp, MG and alcohol.

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

Spur overwork of the brain

Drugs can also stimulate the work of the brain or what are often called stimulants, resulting in a feeling of freshness and enthusiasm, increased self-confidence, and close relationships with other people. However, this can lead to sleeplessness, anxiety, a faster heartbeat and increased blood pressure. Examples are amphetamines, ecstasy, methamphetamine, cocaine and nicotine found in tobacco.

Trigger hallucinations

There are also drugs that cause delusion, or which are also often called hallucinogens. An example is LSD. Apart from LSD, cannabis has various effects, such as changing perceptions of time and space, and increased imagination, so that marijuana can be classified as a hallucinogenic.

In brain cells there are various chemicals called neurotransmitters. These chemicals act on the junctions of nerve cells with one another (synapses). Some of these 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 by affecting one or more neurotransmitters. The neurotransmitter that most plays a role in dependence is dopamine.

Effects of drugs on the nervous system

Drug abuse has an influence on the work of the nervous system. Anything? Here's the explanation.

• Sensory nerve disorders. This disorder causes numbness and blurred vision which can lead to blindness.
• Autonomic nerve disorders. This disturbance causes unwanted movement through motor movements. 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 is without coordination with the motor system. For example like someone else ' on ', the head can wobble on its own, it only stops when the drug wears off.
• 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 don't use them.

In the long term, drugs can slowly damage the nervous system in the brain from mild to permanent. When using narcotics, the electric charge in the brain is excessive, if you are addicted, the nerves can be damaged over time. Do you want to be blind, have a conscience, or go to prison on purpose for drugs?

How do drug users become addicted?

So, what happens to someone who is addicted? Addiction is a kind of "learning" brain cells at the pleasure center. When you try to take drugs, your brain will read your body's response. When you feel comfortable, your brain releases the neurotransmitter dopamine and makes a pleasant impression.

The brain records it as something that it seeks as priority because it is perceived as fun. As a result, the brain makes wrong programming, as if the person needs it as a basic need and there is an addiction or dependence. In a state of dependence, the addict feels very uncomfortable and in pain. To get drugs, he will do everything he can, such as stealing, even killing.

In cases of dependence, a person must always use drugs, otherwise, withdrawal symptoms (also known as withdrawal) occur, if the use is stopped or the amount is reduced. Symptoms depend on the type of drug used.

Symptoms of opioid withdrawal (heroin) are similar to those of a severe flu, namely runny nose, tears, standing body hair, muscle aches, nausea, vomiting, diarrhea, and difficulty sleeping. Drugs also interfere with 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 the dosage until they 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, damaged relationships with family and friends, damaged moral life, dropping out of school., unemployment, and the ruin of his future.

Consuming drugs continuously causes an increase in body tolerance so that the user cannot control its use and tends to keep increasing the dosage until finally the body can no longer accept it. This is known as an overdose.

Nerves are one of the important organs in humans that regulate body systems. If it is damaged, it can cause permanent disability and is difficult to repair. You don't want to be disabled just because of drugs?
