A popular beverage that was created in partnership with the Bob Marley family and sold in some New Jersey schools has been banned after its stated effects made children feel sleepy and ill, according to Fox News.

Marley’s Mellow Mood, which is typically found in convenience stores and gas stations, is part of a new trend of “relaxation” products.  The drink, which prominently features an image of the late reggae star on its label, was also available for sale at the William R. Satz School and Holmdel High School in Holmdel, N.J.

The beverage contains valerian, which is a medicinal herb that has not been subjected to extensive testing.  Valerian is used for treating insomnia, stress, and anxiety, and there reportedly hasn’t been much research done on the potential effects it has on children.

Ironically, the beverage’s label has a warning that indicates it may cause drowsiness and is not intended for children.

The Marley family drink also contains other ingredients, such as lemon balm, hops, passion flower, and chamomile.

The company issued a statement in which it said it takes this situation very seriously.

It’s unclear what the students’ symptoms were.
