Drug addiction and substance abuse Consumption of various drugs - drug addiction - a real scourge in many countries of the world. Often the first step towards drugs is taken out of curiosity (up to 60% of drug addicts have "tried" drugs for the first time this way). At the same time, everyone is convinced that he personally can always stop if necessary. But this is a profound delusion. Usually, years pass before a drunkard becomes an alcoholic, while drug addiction is formed within a few months, and the process of degradation is so fast that at the age of 30-40 a drug addict is already a very old man. From psychological addiction to physical dependence takes only 2-3 months. Addiction - a disease resulting from the abuse of drugs and narcotic active substances. Drug addiction is manifested by the constant need to take narcotic substances, since the mental and physical state of a person depends on whether he has taken the drug he needs or not. Drug addiction leads to a gross violation of the body's vital functions and social degradation. Addiction It is a disease with a chronic course, which begins gradually. The cause of the disease is the ability of narcotic substances to cause a state of intoxication, accompanied by a feeling of complete physical and mental comfort and well-being. The development of a painful addiction to drugs is the conscious use of drugs in order to obtain the effect of drug intoxication. As a rule, emotionally unstable, mentally immature, dependent, prone to imitative actions, extremely selfish, whose interests are limited to elementary needs, tend to do this. Such people lack self-control, so the desire for intoxication does not meet with internal resistance, drug addiction develops quickly and is accompanied by the absorption of large doses of narcotic substances. Drug addiction begins with repeated drug use due to the desire to again and again experience the sensations caused by drug intoxication. Without taking a drug, a person experiences dissatisfaction, he lacks "something". Calm and pleasure brings only the next use of the drug. This is how drug addiction is formed. Addiction is painful because it does not reflect a natural need and gradually suppresses and displaces natural drives. As the drug is used, the effect of the drug weakens, and the patient is forced to increase the dose of the narcotic substance in order to achieve the same effect. Intoxication becomes pleasant rather because the state of sobriety is unpleasant, the person becomes restless, tense, unable to concentrate on anything, distract from thoughts about the drug. Only the introduction of the next portion of the drug brings him to a "normal" state. This is how addiction develops. Substance abuse is formed according to the same principles, only drug addiction is associated with potent and psychotropic drugs. According to the World Health Organization, drugs have taken the first place among the culprits of premature death in people and have already outstripped cardiovascular diseases and malignant tumors.
