While teens may think the condom snorting challenge goes without consequences, it can be dangerous, Bruce Y. Lee, a Forbes contributor and associate professor of International Health at the Johns Hopkins Bloomberg School of Public Health, said in a recent column.

Lee writes that with the exception of doctor-prescribed nasal sprays, “anything else that goes up your nose can damage the sensitive inner lining of your nose, cause an allergic reaction, or result in an infection.”

He notes that the condom could also get stuck in the nasal cavity or the throat and cause someone to choke.
