There are thousands of videos on YouTube with young people trying something called the "cinnamon challenge." People try to swallow a spoonful of cinnamon in less than a minute without any liquid. They sputter, cough and choke from the dry powder.
"If you think about it, there's nothing about this that makes people feel good, except maybe looking at the video after the fact," said Dr. Steven Lipshultz, professor of pediatrics at the University of Miami Miller School of Medicine. "And for some, it could have short-term or even lifetime health risks."
