Some research suggests that combining caffeine with alcohol may reduce the release of dopamine, the hormone that produces the feeling of happiness that comes from alcohol. This could theoretically diminish the enjoyable drinking experience. But as the doctor points out, such conclusions are made on the basis of animal experiments and are of academic importance only.
In practice, both substances (caffeine and alcohol) are psychoactive and their uncontrolled use can lead to serious consequences. Risks include the development of mental addiction, problems with the cardiovascular system, disorders of the gastrointestinal tract and nervous system, as well as mental illnesses.
The doctor especially warned against the simultaneous use of caffeine and alcohol, considering them harmful to health.
