What do drugs do?

The human body is able to excrete toxins, the body copes with them without too much difficulty. Drugs are toxins. But the study of these toxins involved drug treatment. In medical terms, drugs are toxic substances that can have a negative effect on the human body. Constant use of drugs leads the body to addiction, as well as violates its activities.

The effect of drugs largely depends on the volume of the dose. If the body has received a small amount of toxic substances, then it becomes active. A large number of toxic substances, by contrast, have a calming effect on the body. Treatment methods for drug addiction depend on the type of narcotic substances. In this article, you can read about what drugs do to people and how they affect the human body.

Effects of drugs

If viewed from the side of psychopharmacological influence, the effects of narcotic substances can be divided into three main groups.

  • Narcotic drugs that inhibit the central nervous system.These substances are able to relieve mental stress, reduce self-doubt or fearfulness. The emotional reaction to pain changes, coordination of movement is disturbed, and intelligence slows down. The use of such drugs in excessively large quantities causes sleep, a violation of consciousness occurs and, in the worst case, death. The effects of such narcotic substances are used not only in medicine, but also among drug addicts are very popular in order to create a short-term illusion of pleasure.
  • Narcotic substances that excite the central nervous system. From the name it is clear what the drugs do with the body. These substances stimulate the higher nervous system, prevent falling asleep and remove fatigue. The minimum dose of such drugs causes the body to work actively, dulls the feeling of hunger. Overdose causes aggression, anxiety, persecution and hallucinations. For medical purposes, these substances are used to relieve fatigue, drowsiness, if a person is obese, then to reduce appetite.
  • Hallucinogenic drugs. These narcotic substances violate the psyche, distort the perception of time and space, moreover, change the perception of himself. Being under the influence of hallucinogenic drugs, a person moves to another world, more vibrant and colorful. At these moments, visual sensitivity increases, leading to hallucinations. In medicine, there are a number of terms related to hallucinogenic substances: hallucinogens are substances that cause hallucinations; psychotomimetics - lead to a state resembling psychosis; Fiction - substances that cause fantastic vision and more.

The effect of drugs on the body

It is worth understanding how drugs affect a person and his body as a whole.

The effect of drugs on breathing

Consider what breathing drugs do. It is the main condition for human life. Of course, we all know that when we breathe in, we get oxygen, and we exhale carbon dioxide. The body itself regulates the depth and frequency of breathing. Chemoreceptors that are activated by carbon dioxide are involved in the regulation of respiration.When the amount of carbon dioxide exceeds the norm, the receptors are excited and transmit information to the respiratory center. And the respiratory center, in turn, increases the frequency and depth of your breathing.

Narcotic drugs interfere with the work of chemoreceptors, because of this, an excessive amount of carbon dioxide is accumulated. Then decreases the activity of the process of respiration. The addict will not be able to breathe fully. Often, drug addicts die because of respiratory arrest.

The effect of drugs on coughing

When an obstacle to the passage of air in the respiratory tract occurs, it is then that a cough occurs. By coughing we give impetus to this obstacle, thereby eliminating it. This is a kind of protective reaction of the body. Drugs reduce the activity of the cough center. Previously used drugs for cough, with the content of drugs. A person who uses drugs turns off the cough mechanism, as a result, sputum, dust, and smoke begin to accumulate in the lungs, gradually turning the lungs into an urn with dirty spitting.

The effect of drugs on cardiovascular activity

Consider what drugs do with the cardiovascular system. Everyone knows how important the body for the full work of the heart and blood vessels. It is these organs that are responsible for the transportation of vital substances, as well as the removal of harmful particles from tissues. But drugs inhibit the work of the vasomotor center, this leads to a slow pulse. The addict will never be able to overcome the usual amount of work.

The effect of drugs on the digestive system

Food is simply necessary for us to live. Together with food all the most necessary substances that support the full activity of the body enter the body. Drugs disrupt digestive processes. Addicts are deprived of a full taste and olfactory sensations. They do not enjoy food. Food completely ceases to digest. Using drugs, a person condemns himself to constant starvation.

Drugs are the most harmful substitutes for real pleasure. You should not give preference to narcotic substances for pleasure, because you can choose another way to get pleasure from life.
