“Bobby, Stop Smoking That Candy.”

What will kids think of next:

Summit Middle School in Frisco, Colo., is a tobacco-free campus. Students who smoke cigarettes are suspended.

But when a lunchtime crew of sixth-graders last fall started “smoking” Smarties, the tart, chalky candy discs wrapped in cellophane, lunchroom monitors and the school nurse were flummoxed.

The children didn’t light the candy. They crushed it into a fine powder in its wrapper, tore off one end, poured the powder into their mouths and blew out fine Smarties dust, mimicking a smoker’s exhale.

“It was freaky,” says Corinne McGrew, a nurse for Summit School District. “My biggest concern was that they would aspirate the wrapper or a whole Smarties and it would be a choking hazard.”

The fad at Summit Middle School died down after a few days and some harsh words from the lunchroom staff. But at other schools and across the Internet, “smoking Smarties,” as the activity has been labeled, is gaining popularity. Some children have even taken to snorting it, all to the horror of parents, teachers and the 60-year-old company that manufactures the candy . . . .

Oren Friedman, a Mayo Clinic nose specialist, cautioned that frequent use could lead to infections or even worse, albeit rare, conditions, such as maggots that feed on sugary dust wedged inside the nose.

Yes, kids, you heard that right: Maggots.
