This paper examines the harmful effects of alcohol and drug consumption in children and young people, as well as the quantitative research conducted on this topic. In order to approach and explain the problem of this phenomenon, we should first of all properly explain alcoholism and its elements. The term alcoholism refers to the uncontrolled consumption of alcohol in which alcohol is an obsession in the life of an individual and has negative and destructive implications on everyday life and relationships with the environment.. Alcohol has a direct toxic effect on the liver, brain, heart and the entire cardiovascular system. Continuous absorption of significant amounts of alcohol over time results in the development of tolerance to the intoxicating effects on a psychological, physical and cognitive level. Although the level of tolerance is increasing, the level of health and quality of life is decreasing, which brings these two variables into an inversely proportional relationship. Considering the age and developmental process in which children and adolescents find themselves, the effects of alcohol on the organism are multiplied. In order to gain a better insight into the attitude and beliefs of children and young people about alcohol and drug consumption, a study was made and carried out, the purpose of which was to examine attitudes about alcohol and drug consumption, knowledge about harmful effects, the effects that alcohol and drug consumption brings with it, ways information, reasons for experimenting with alcohol and other intoxicants, and general effects on health and further development. Prevention measures at the family, educational and community level are considered the best protection against the onset of alcohol and drug consumption among children and young people. If the existence of problems related to the consumption of alcohol or other intoxicants is observed through the monitoring of children through counseling, health education or systematic examinations, it is extremely important to provide adequate help that will respond to the needs of the individual.
