(CNN) - Nine Central Washington University students hospitalized this month after an off-campus party were sickened by "Four Loko," a caffeinated malt liquor also known as "blackout in a can," according to a police investigation.
Investigators concluded that none of the students were drugged or given alcohol without their knowledge and no sexual assaults occurred, according to a school statement.
The findings convinced university President James Gaudino to ban "alcohol energy drinks" from his campus. CNN's senior medical correspondent, Elizabeth Cohen discussed the concerns raised over the drink.
