Let us begin with the impact of alcohol on the informational low-frequency processes in psyche that have similar duration as the lifespan of an individual. What happens when the alcohol content exceeds the frequency of the body's natural level?
The red blood cells in the blood begin to ball up in big quantities. The blood vessels of the brain are different: some vessels are so thin that they are unable to let through two clotted red blood cells. What happens as a result of this? - Some groups of neurons will be deprived of oxygen and die. Neurons are known to never regenerate under the current human physiology. Those information and algorithmic processes that take place on the basis of the neural networks consisting of these neurons will collapse which will lead to the loss of information in the psyche of an individual.
In addition to the fact that intelligence activities will be perverted within the time when a stupefied individual sleeps it off, and the level of alcohol and alcohol toxins comes to the natural level, the mosaic world view will lose some meaningful units and the links between them will break or distort: the mosaic will become less detailed and complete, and some of its fragments will break into a kaleidoscope. This means that simulating some processes in order to assess the situation and its potential for change on the basis of a damaged mosaic world view will be more rough and less detailed in terns of accuracy of the predicted future. Accordingly, this will reduce many processes that can be managed by this individual, so his attempts to control the progress of such processes, whose modeling errors have exceeded the critical level in his psyche, would inevitably result in the collapse of controlling.
The neurons killed by alcohol do not recover. But the psychic algorithms are such that the effects of alcohol shock are followed by the process of restoring of the destroyed mosaic world view: the lost meaningful units and the links between them will start restoring. The performance of this process is that after 100g of vodka, new year’s or wedding glass of champagne (12% 200-250 g ), half a liter of beer (with volume of 6%) it will take about three years before the intellectual activity can reach again its potency and the damage caused by a single case of intoxication (that is nowadays considered as slight) is compensated. And such individual gets blocked from controlling sufficiently long-term (low-frequency) processes at least for three years. During these three years a lot of things may happen, and not any processes, once left, can be entered again ...
The brain of those who systematically have "light" alcoholic liquids, even if they do not get stiff, becomes a cemetery of neurons killed by alcohol. That is approximately how F. Uglov, academician of the USSR Medical Sciences Academy, described the effects of alcohol on the structures of the brain in his books "In the captivity of illusions" and "Out of the captivity of illusions."
Of course, an individual has the right to choose the alcoholic method of suicide. But here we are talking about personnel policy; above all, in the domain of controlling, which predetermines life of society as a whole. And since the impact of controlling process, deteriorated by alcohol, has to be cleared up by the entire society, a time will come when self-intoxicating policy makers will not have the right to say, that they did not know that and were not warned ... This text is a warning.
Without going into these details, some of which are visible only under an electron microscope, for centuries Islam and many occult and magical schools insist on absolute soberness of their followers, taking care of their highest capacity. The Christian churches call their flock for unsober sacrament, intimidating the objectors of alcohol with everlasting hellfire: that is cringe worthy. And the secular pseudoscience and publicism keep promoting "civilized intoxication": purporting that one does not have to intoxicate oneself blind, but moderately to make life funnier and less stressful, to get the cholesterol out of your body and so on and so forth.
While the problem of stress is solved by forming a personal culture of perception and understanding of life, with a behaviour which, firstly, eliminates unexpected troubles, referred to as "stress", and secondly, whose representative in society is emotionally self-sufficient and does not need "amusing" substances; as for the problems of cholesterol, heart attacks, strokes, oncology, these are the problems of violated healthy lifestyle and eating habits that are consistent with genetic settings of the physiological nature of homo sapience.
The described mechanism of alcohol impact on the mosaic world view leads to the fact that there is no simply talking on some topics to a person who regularly has beer: to get the hang of such topics requires a certain level of developed mosaic world view (detail and sufficient number of links between meaningful units), but this level is not achievable for a person because he systematically destructs his information and algorithmic processes of long duration.
If someone reading these lines and belonging to the category of those who get intoxicated regularly although in small quantities, immediately accepts absolute soberness with regard to alcohol, cigarettes and other legal (and illegal) drugs, it will take at least three years before he realizes how much there is behind this text. If such person doesn't go into absolute soberness, he will keep considering the above words to be irrelevant nonsense.
The other side of the impact of alcohol, other drugs and psychotropic substances is that intelligence is a bio-field process. With respect to the body of human beings, one can introduce the notion of genetically normal settings for bio-fields: this includes a list of fields, frequency characteristics (carrier and clock frequencies, phase shifts), polarization, transmit-receive surfaces (bioantennas) and waveguides in the body, etc.
These settings of the bio-field system are normal by themselves, when an individual who does not have any inborn deviations from a standard norm in his chromosome sticks to the right bio-rythm, when his diet does not have any products alien to his genetics. The latter, in particular, does not presuppose injection of alcohol from outside, nor does it include cigarettes and other drugs; in addition, it should be borne in mind that anatomically (i.e. genetically) a human being is not carnivorous.
By introducing alcohol and other drugs into their allowance people alter genetically normal setting of their biofield system. This results both in distorting the work of the mind itself and letting the individual psyche take in a flow of such informational streams that are not acceptable under genetically normal setting of the bio-field system. As a result, the information background which tiles the mosaic is distorted; previous links between meaningful units break; information streams alien to normal genetics produce information modules alien to normal mindset of humanity, part of which, if we do parallels with the computer world, in their functions and influence, are similar to installers of complex information products and computer viruses (some of them in the past used to be called "dickens", overwhelming an individual and people affected by them used to be called "obsessed").
As a result of all this - alien to genetically normal setting of the bio-field system, - an individual may cease to be himself if not to lose his ability to be human at all. In less severe cases, there is "mere" distortion and destruction of the mosaic world view.
By consuming any drug or almost any psychotropic drug, an individual opens some kind of information channel into his psyche. This channel may allow two-way information movement. If so, by opening such a channel, an individual is able to exert influence on the outward things if he has sufficient self-command and willpower. In this case, he will become a "shaman", whose practices are based on the intentional narcotization of himself and others. But shamans are few. The victims of shamanism and shamans are far more: Shamans got the north-American Indians addicted to tobacco because tobacco opened a free channel for shamans to enter the psyche of each weak and less knowledgeable member of the tribe, but all that has ended in the collapse of their civilization.
