Dragon's Breath is puffy cereal that's been infused with liquid nitrogen. It produces smoke-like vapors that spew from the eater's nose and mouth, giving the snack its name.
Also sold under the names Heaven's Breath and Nitro Puff, it is especially dangerous for children with asthma, the FDA said.
It warns against buying the product because it can cause:
Severe damage to skin and internal organs if mishandled or accidentally ingested due to the extremely low temperatures it can maintain. Breathing difficulty by inhaling the vapor, especially among individuals with asthma. Life-threatening injuries.
