How much coffee to drink per dayPhoto:ShutterstockIt turned out that people who enjoy caffeine in coffee and energy drinks often enjoyed amphetamines and cocaine, and in large doses. Such conclusions were made during a survey of 22 people and a placebo pill. Later, they were offered an amphetamine pill, after which the study participants had to record their impressions. As a result, most people who chose caffeine also spoke positively about the narcotic substance. According to the professor, the data obtained will allow us to better identify people predisposed to drugs, since addiction is based on the body's response to psychomotor stimulants. Recall that earlier scientists managed to prove that the invigorating effect of coffee may be just an illusion.
