LIBERTY, Ky. - Two students have been suspended from school and criminally charged after inhaling a toxic cleaner on school grounds.

The two boys - ages 17 and 16 - are each charged with one felony count of selling or giving a volatile substance on school property and possession of a volatile substance, a misdemeanor.

The two boys and three other students were taken to Casey County Hospital Tuesday after they were caught inhaling Air Duster, a dust cleaner for computers, typewriters and telephones, said Sgt. Joey Miller with the Liberty Police Department. The incident occurred in a classroom at 11:40 a.m.

Miller said the juveniles were placed on heart monitors for an hour and were given fluids intravenously.

"It says in bright red letters on the can: 'inhaling contents could be fatal,' " Miller said.

"They seemed to be doing it for the ultimate high."

Miller said inhaling the substance has the same effect as sniffing gasoline.

It also causes a high-pitched voice.

The two boys were released to their parents. All five students were suspended from school.
