It is impossible to give an unambiguous answer to the question of how drugs act on the body. Each species produces a specific effect. However, in general, they give a short-lived sense of friendliness, flight, fun and lightness. During the period of their impact, all problems seem to be easily solved and insignificant. After the effect of taking the drug dies away, all unsolved problems are returned. In this case, psychological dependence arises. After all, you can get away from problems without solving them.
In order to understand how drugs act, you need to find out what they are for the body. At its core, it is poison. Their impact and impact on the human condition, depends on the dose taken. A small amount is exciting. A large dose can inhibit activity. An even greater number of them can be fatal, showing the effect of the poison. In many areas of human life, we can observe the effect of drugs on the body. This may be the effect of a cup of coffee, psychotropic drugs, alcohol and nicotine.
The effect of drugs is manifested in blocking sensations. They may have the desired result in the fight against pain, however, they will certainly destroy abilities and blur thoughts.
The signs of drug addiction can be said in the affirmative if the body is already accustomed to involving exogenous substances in its metabolism, without which the normal functioning of all systems and organs for a long time becomes impossible. The manifestation of dependence is expressed in withdrawal syndrome. The so-called "breaking" occurs as a result of the cessation of the intake of elements that produce effects on the central nervous system, and the restructuring of metabolism. Symptoms in the form of which withdrawal syndrome manifests itself can be expressed by mild discomfort and a feeling of heat, as well as twisting of joints, cramps and severe pain.
Dependence on narcotic substances is divided into two types. It can be physical and mental. Addiction becomes the cause of the formation of a conditioned reflex, which will accompany a person all his life. This dependence refers to the mental mind and is associated with obtaining pleasant sensations. How do drugs that cause physical dependence? They simply change the metabolism that occurs in the body.
Addiction is a pathology. Its cause is dependence on psychotropic substances or addictive drugs. This is a serious illness, a manifestation of which is the constant need for the use of drugs. The mental and physical condition of the patient is directly dependent on their admission. Drugs interfere with the vital functions of the body, exerting a negative effect on all its functions.
Psychologically, their action leads to social degradation. How do drugs affect the development of this disease? Slowly and gradually they lead him to a chronic course. This is due to the ability of drugs to cause a feeling of intoxication, which is accompanied by the appearance of complete health and well-being. Poisons slowly but constantly destroy the human psyche and brain.
Addicts die from tearing of the heart muscle or from thinning of the nasal septum, which cracks, causing fatal bleeding. Acceptance of a poisonous potion leads to dysfunction of the respiratory system.
The effect of drugs is the cause of the loss of sensitivity of chemoreceptors. In this case, there is a decrease, and then inhibition of the function of the respiratory center. The body experiences constant oxygen starvation. In this case, a fatal outcome occurs from respiratory arrest or unintentional overdose. Drugs adversely affect digestion mechanisms, the functioning of the cardiovascular system and sexual functions.
