Caffeine consumption by adolescents and young adults

Abstract Caffeine is considered a legal psychoactive substance, but its consumption in large quantities can cause specific significant psychophysiological symptoms in both adults and adolescents. Adolescents and young adults consume caffeine primarily in the form of coffee, tea and energy drinks, which in the case of the latter may pose a risk to their health, because the caffeine content in energy drinks is different (sometimes large, exceeding the amount of caffeine in a cup of coffee), which as a result can result in various psycho-physiological symptoms in the form of a feeling of arousal and insomnia, but also heart rhythm disorders, or even (in some people with higher doses of caffeine) significant mood disorders and aggression.
