Chicago alderman Ed Burke brought his proposed ban on those popular energy drinks to a council committee today.
He discussed the details of his plan to ban all energy drinks with more than 180 milligrams of caffeine.
Coffee with higher levels of caffeine would be not be included in the ordinance.
Burke says the drinks are dangerous for kids and teens and he suggests parents should know what their kids are drinking.
The makers of the drinks say they are safe.
The committee did not vote on the ban – but they agreed to discuss it further on another date.
If approved Chicago will become the first city in the U.S. to ban the drinks.
