Deputies from a Siberian republic are calling for a nationwide ban on the sale to children of energy drinks containing alcohol.
The drinks are not currently classified as alcoholic, though in addition to alcohol, they also contain very large doses of other stimulants.
Doctors say this can cause a range of problems, including insomnia and heart disease. The regular consumption of energy drinks is also said to encourag teenagers to drink alcohol.
Alcohol-containing energy drinks are most popular among 10 to 17-year-olds in Russia.
