A parent in Florida is warning other parents of asthmatic children not to eat “Dragon’s Breath,” a liquid nitrogen-coated cereal-like candy that makes smoke come out of a user’s nose and mouth, after her son suffered an asthma attack after eating it.

We knew he couldn’t breathe, and we knew that we couldn’t get him to the hospital in time.” The McKennys found a fire station, where the firefighters gave Johnny albuterol, an IV and an epinephrine injection before taking him to the hospital. Johnny is now recovering at home.
