When 15-year-old Emma Caldwell posted her first “dusting challenge” video on TikTok, she never imagined it would be the last. In recent weeks, a reckless new trend dubbed “dusting” — inhaling compressed air from canned dusters to achieve a brief high — swept through social media, luring teenagers with promises of an adrenaline rush. But for Emma, the thrill turned tragic: she collapsed at home on June 12 and could not be revived. Now her devastated parents are issuing an urgent warning to families everywhere to recognize the hidden dangers lurking behind viral stunts.
Emma’s mother, Lisa Caldwell, told NBC News that her daughter seemed “happy and healthy” just hours before. “She was joking about how silly the trend was,” Lisa said. “Then she gasped for air, fell backward, and never woke up.” Paramedics arrived within minutes, but Emma’s heart had already stopped. An autopsy confirmed acute asphyxiation and cardiac arrhythmia triggered by inhalant toxicity from difluoroethane — the propellant in many canned air dusters.
“It seemed harmless — a quick buzz,” says grieving father Mark Caldwell. “We never thought a can of air could kill our little girl.” #DustingDanger— NBC News (@NBCNews) June 15, 2025
The “dusting” trend involves removing the nozzle from an air-duster can, placing one’s lips around the opening, and inhaling deeply. Teens describe fleeting euphoria, dizziness, and giggles, unaware—or unconcerned—about the chemical’s effects on the heart and brain. According to poison control data cited by the CDC, inhalant abuse accounts for more than 45,000 emergency visits annually in the U.S., with compressed gases responsible for a growing share.
Social media influencers initially framed the practice as a harmless prank, posting step-by-step guides that went viral. One popular clip by @TrendTokGuru showing a teen “dusting” and then dancing in slow motion amassed over 10 million views before TikTok removed it for violating its “dangerous challenges” policy. Yet countless reposts persist under hashtags like #DustingChallenge and #JustDustIt.

In a joint alert, the American Academy of Pediatrics and the National Association of School Nurses urged educators to discuss inhalant dangers in health classes, noting that “half of youth aged 12–17 experiment with inhalants before graduation.” Their statement, featured on AAP’s website, emphasizes that products like keyboard-cleaning dusters often contain difluoroethane or tetrafluoroethane, which can induce fatal arrhythmias by sensitizing the heart to adrenaline.
Emma’s case isn’t isolated. In January, 14-year-old Darius Miller died under similar circumstances in Ohio after inhaling from a can of duster he found in his dad’s garage, as reported by The Plain Dealer. In March, two California students suffered seizures and hospitalization following the trend, prompting a school district-wide ban on bringing canned air to campus.

Experts agree that legal restrictions alone won’t stop the craze—education and parental vigilance are key. The Substance Abuse and Mental Health Services Administration recommends parents store dusters and other aerosol cans out of reach and discuss the life-threatening risks openly. “Silence feeds the myth of safety,” says SAMHSA director Dr. Juan Melendez in an interview with USA Today.
In the Caldwell household, life has been irrevocably altered. Younger brother Tyler, 10, clutches Emma’s sketchpad each night, while Lisa Caldwell started a support group called “GunnerStrong” in her memory—named after Emma’s beloved stuffed bear “Gunner”—to help other bereaved families share resources and grief counseling.
“We never imagined a can of air could endanger our child,” writes Lisa Caldwell on the group’s page. “If one parent learns from our tragedy, Emma’s life will have made a difference.” #GunnerStrong— Caldwell Family (@CaldwellFamily) June 16, 2025
As the investigation into Emma’s death continues, coroner Michael Reed urges communities to treat inhalant abuse with the same gravity as opioids or vaping. “Compressed gas kills silently and instantly,” he said in a press conference covered by The Washington Post. “We need policies, awareness, and swift intervention.”
Parents, educators, and teens themselves share their survival stories under #DustingSurvivor, describing dizziness, hallucinations, and near-fatal heart palpitations. Many recount how mere seconds of inhaling the gas triggered panic and long-term anxiety.
“I blacked out for ten seconds and woke up on the bathroom floor,” writes one teen. “Never again.” #DustingSurvivor— Anonymous (@InhalantAbuse) June 16, 2025
Retailers are also taking note: major office supply chains like Staples now require customers to show ID for bulk aerosol purchases, a policy change announced on their corporate site. Some states, including California and New York, are moving to reclassify canned air as restricted inhalants, subject to age verification.
Emma’s untimely death stands as a heartbreaking testament to how quickly curiosity can turn deadly in the digital age. Her parents’ plea is simple yet urgent: talk to your kids, secure dangerous household products, and recognize that viral challenges can carry real-world consequences. Because in a heartbeat, laughter can transform into loss—and a moment’s thrill can steal a lifetime.
