Doctors are once again warning about the "Cinnamon Challenge," after a new study found an increasing number of calls to poison control centers about the YouTube fad in which teens compete to swallow one tablespoon of cinnamon in under 60 seconds without drinking water. The researchers at the University of Miami's Batchelor Children's Research Institute found that in the first half of 2012, poison control centers received triple the number of calls about the Cinnamon Challenge than they had in the entire previous year. Kids can experience severe coughing fits, choking, or catch pneumonia from the game. The study authors also say cinnamon is made up of cellulose fibers that don't dissolve or biodegrade, and swallowing so much of it can lead to lesions, scarring, and inflammation of the airways and lungs. Other effects may include a chronic lung disease called progressive pulmonary fibrosis and doctors are especially concerned about the effects on kids with asthma, pulmonary cystic fibrosis, chronic lung disease or a hypersensitivity to the spice.
