Richmond schools to use aerosol spray to detect drugs

A school system in the eastern Georgia city of Augusta plans to use a unique method for identifying students who use illegal drugs. Here's how it works: Coat a desk or a locker with aerosol spray. If the object turns a different color, the student may be using illegal drugs.

Richmond County school officials say using the spray would be less intrusive than bringing in police dogs or conducting urine tests. It can detect marijuana, cocaine, heroin and amphetamines.

"We could actually, rather than testing the student, we may opt to go to their locker," said Dr. Dana Bedden, Richmond County's school superintendent. "It could be a parent who comes to the school and say I may be concerned that my child might be involved, and we can offer a resource to them to say do you have any of their clothing or anything that you may want to have us test."

The spray is part of a research study funded by the federal government.
