The Jones County Sheriff's Office issued a warning for parents in Jones County Tuesday night.
The sheriff's office says within the past 24 hours, two students went to the hospital after possibly taking LSD.
They posted a photo on Facebook of the paper the students digested. Officers think it's LSD but want to have it tested to make sure.
The Facebook post says they made two arrests in the case.
The sheriff's office is advising parents to make sure their kids haven't taken the substance and don't have contact with it.
They are asking anyone with information to call them at 478-986-3489.
