What is the 'dusting' challenge? 19-year old dies after participating in viral trend online

A 19-year-old Arizona teenager has died after participating in a deadly social media trend called the “dusting challenge,” sparking urgent warnings from doctors and devastated parents.

Renna O’Rourke was declared brain dead after inhaling computer dusting spray—a form of inhalant abuse known as “dusting” or “chroming”—that replaces oxygen in the body, causing sudden organ failure.

Renna’s father, Aaron O’Rourke, confirmed her death on June 1 after four days in intensive care. “She always said, ‘I’m gonna be famous, Dad. Just you watch. I’m gonna be famous,’” he told AZ Family. “Unfortunately this is not under the most optimal of circumstances.”

The “dusting” trend has gained traction online among teens, who inhale cleaning sprays to feel temporarily euphoric. Dr. Randy Weisman of HonorHealth Scottsdale Osborn Medical Center said, “It replaces the oxygen within their lungs and body,” noting it can lead to heart failure, liver damage, and death.

Renna’s official cause of death was sudden sniffing death syndrome. A GoFundMe page set up by her father is raising funds for medical and funeral costs, and aims to spread awareness of the lethal consequences of inhalant abuse.

The family is urging parents to take action. “Don’t trust. That sounds horrible, but it could save their life,” Dana added.
