Authorities say six New York high school students who were checked out at a hospital had eaten a candy bar containing marijuana.

School officials said Friday afternoon that the students from Sachem (SAY-chem) High School North on Long Island were all OK.

Authorities said they went to a hospital as a precaution after consuming candy that made them "uncomfortable." All were later released.

Superintendent Dr. Ken Graham says the candy bar was prepackaged with a label indicating it contained marijuana.

It's unknown where the students obtained the candy bar.

Graham says school officials are taking the incident "very seriously" and are reviewing the situation.
