The choking game has been around for decades, billed as a "safe" way to get a rush or a high from passing out. According to a new study, about 6 percent of adolescents have played it at least once. But doctors believe kids who play it may have little idea how deadly it is.
In the choking game, a person cuts off oxygen and blood flow to the brain with a towel, belt or rope, or hyperventilates until they pass out. When the blood and oxygen rush back to the brain, it creates a euphoric high.
