A 15-year-old student at Conway High School was suspended for 10 days following a report by a fellow student to school officials that he was in possession of suspected marijuana.

The school's assistant principal searched the student and located a clear plastic bag and a small clear bottle, each containing a green leafy substance.

The assistant principal provided a voluntary statement. The student told school officials the substance was salvia, bought from an online store under the "legal high" section.

The substance was submitted to the Arkansas State Crime Lab for testing.

Police say criminal charges could follow pending the outcome of lab analysis.
