COLUMBIA, Tenn. -- A mysterious drug that left two teenagers almost unconscious Friday night at the Maury County Fair may have been taken by some other kids as well, said police.

The teenagers were taken to the hospital after they were found on the verge of passing out.

Channel 4's news partners at the Columbia Daily Herald newspaper reported that Sheriff Enoch George believes there are other teens who took the unknown substance.

Authorities have sent the drug they believe that was used to a lab for analysis.
