The impact of drugs is a voluminous question about the negative effects of drug use. However, a lack of awareness of the specific impact of drug use is the leading cause of the spread of the disease.
It is important to know how drugs affect the body, to understand what specific consequences await a drug addict - in relation to his physical and mental health, cognitive processes, and abilities.
All narcotic substances of natural or synthetic origin are a poison that destroys the human body. From the beginning of their use, they become part of the metabolism and have a tangible effect on biochemical, endocrine processes (otherwise drugs would not have a powerful psychotropic effect). Therefore, mental influence is not the only result of use, every organ system is subject to the influence of drugs.
The respiratory system is not only negatively affected when the patient smokes the drug. The ingestion of tar, poisons, soot into the lungs when smoking is not the only negative consequence.
If drugs are used in a different way (heroin, morphine), the cough center of the brain is suppressed. Cough is a protective reaction of the body and a way to free the lungs from mucus, dust, foreign particles, and when this important reflex is inhibited, excess substances continue to remain in the lungs, provoking the multiplication of bacteria, a high risk of lung infections.
Features of the effect of drugs on the heart
The effect of drugs on the heart has a different mechanism depending on the type of substance used.
Opiates (heroin, morphine). They provoke oppression of the centers of regulation of the work of the heart muscle and blood vessels. The effect of drugs on the human body is to lower blood pressure and heart rate, the body experiences hypoxia - oxygen starvation, there is a violation of the metabolic processes of the heart muscle. The risk of developing her dystrophy increases, deterioration of heart function closes the vicious circle of "hypoxia-cardiac dysfunction-hypoxia".
Stimulants (cocaine, amphetamine, ecstasy). How do drugs affect the body? They cause an increase in heart rate, an increase in blood pressure, an increase in the load on the heart muscle, a spasm of peripheral vessels, an increase in body temperature. Disrupted thermoregulation processes increase the load, the heart muscle is subject to rapid wear.
The result is arrhythmias, heart attacks, dystrophy of the heart muscle, heart failure.
How drugs affect the nervous system
It is known what effect drugs have on the body in relation to the nervous system - especially when one has seen with one's own eyes the consequences of use. However, disorders of its function in the form of three days of insomnia or increased irritability are particular manifestations of a global problem.
It is difficult to overestimate the role of the brain in the regulation of all body processes. When the poison enters the body, it reacts with sharp vasoconstriction - it tries to protect the brain from intoxication. The spasm provides temporary preservation of functions, but together with the poison, useful substances and oxygen cease to flow into the brain. Hypoxia leads to the death of nerve cells, a violation of the metabolic processes of the brain exacerbates the situation. Depletion of the resources of the nervous system leads to the following consequences:
It will take a long time to list all possible complications, and an article on drug use will turn into scientific work. It is difficult to predict how drugs affect the body, what kind of consequences the patient will get - it depends on the damage to specific brain structures.
Deterioration of the functions of the gastrointestinal tract when taking drugs is provided due to the following mechanisms:
The effect of drugs on the body through indigestion is expressed by a stable decrease in appetite, a deterioration in the digestibility of food, spasms, and chronic constipation. This leads to a deficiency of nutrients - vitamins, trace elements, poisoning of the body with its own feces, the decomposition of which occurs in the intestines.
The liver is the first organ that "takes a hit" when using the drug, therefore, over time, it begins to cope poorly with function. The resulting toxins are carried with the blood throughout the body, continue to poison it with the decay products of drugs.
The effect on the human body of drugs in relation to the genitals is unambiguous - the addict has every chance of remaining childless, but even when conception has occurred, the risk of having an inferior offspring is very high.
Infertility applies to both sexes. Impotence, amenorrhea (cessation of menstruation), decreased sex drive are common consequences of short-term use.
In both sexes, structural changes occur - atrophic processes of the genital organs. With the refusal of drugs, their long-term use earlier leads to the impossibility of carrying a fetus in women.
