A spoonful of sugar, sure, but cinnamon? That’s a little tougher.

The principal of Clinton Avenue School, Carmen Ana Rodriguez, has been placed on administrative leave after she saw some students taking the “cinnamon challenge” at lunch, the New Haven Register reported Monday. Apparently the young people are going crazy over the fad, which has gone viral via YouTube videos in which young people try to swallow a spoonful of cinnamon and start coughing violently, gasping for air and sometimes vomiting.

Connecticut’s Department of Children and Families is investigating the matter, and Assistant Principal Sandra Kaliszewski is in charge of the school while Rodriguez is on leave, Chief Operating Officer William Clark told the Register on Monday.
