From March 1 to March 31, 2024, psychologist of NCJSC “Semey Medical University” N. Ersenkyzy  conducted psychological testing for 1st year students of  “General Medicine” and “Dentistry” specialties in order to identify drug addiction, smoking, harmful activities. In general, smoking, alcoholism and drug addiction are widespread among young people. Teenagers do not realize that they are destroying their lives for the sake of satisfying their curiosity. One of the current problems among young people is smoking electronic cigarettes. Much has been said about the problem of smoking and its harm. However, the concern of scientists, educators and doctors caused by the spread of this addiction is growing, since there are a lot of young people who do not consider smoking harmful to health. Smoking is not a harmless activity that can be quit without effort. It is a real drug addiction, and all the more dangerous because it is not taken seriously by majority of people. As a result, many young people end up in hospital with lung disease.
