Marley's Mellow Mood is promoted to reduce stress. The drink's nutrition facts say it may cause drowsiness and is not intended for children.
However, students at Satz Middle School and Holmdel High School could buy it on campus. Several middle school students were sickened on Friday.
The Asbury Park Press reports the school district's food service provider has removed a manager pending an investigation. Chartwells School Dining Services also has removed the Marley product.
The company issued a statement in which it said it takes this situation very seriously.
It's unclear what the students' symptoms were.
