Nobody Told Claudia Dimit's Son That a Can of Computer Duster Could Kill Him. The Label Still Doesn't.

Claudia Dimit’s son died after inhaling difluoroethane — the compressed gas sold as computer-cleaning duster, the kind you’d find in any office supply aisle for under ten dollars. She now runs Families United Against Inhalant Abuse, one of a small number of advocacy groups working a substance category that almost nobody else covers. Between 2021 and 2024, at least 30 Oregonians died the same way hers did — 20 from difluoroethane, 10 from nitrous oxide, ranging in age from 24 to 82. Retired attorney Ray Thomas, who has represented families in these cases, put it plainly: “Very few people know about it. And then, once you find out about it, you realize, ‘Oh my goodness. This is really a problem.’”

Inhalants are the addiction category nobody assigns a beat reporter to, which is exactly backwards, because they’re the only major drug class where the deadliest dose can be the first one.

There’s no tolerance-building curve that gives you a warning. Sudden sniffing death syndrome — cardiac arrest from a single inhalation, most often the first or an early one — can happen to someone who has never used before and has no risk factors a screening tool would catch. That single fact should put inhalants near the top of every harm-reduction conversation. It almost never is.

The chemistry is boring. That’s the problem.

Here’s the plain version: difluoroethane and nitrous oxide are both legal, unregulated-at-the-federal-level products with real industrial and culinary uses — duster for cleaning keyboards, nitrous for whipping cream. Inhaled recreationally, both starve the brain and heart of oxygen fast enough to trigger a fatal arrhythmia, and repeated nitrous use depletes vitamin B12 to the point of causing spinal cord damage — nerve pain, numbness, and in serious cases, paralysis, the same mechanism documented in FDA’s own advisory against inhaling flavored nitrous canister products. None of that requires a lab, a dealer, or an ID that gets checked at most stores. That’s the entire reason this category gets under-covered: there’s no cartel, no scheduling fight, no dramatic bust. Just a can of duster and a kid who didn’t know what it does.

We have been here before, and the pattern is the reason this keeps happening. In the 1980s, a wave of gasoline-sniffing deaths among Native American youth on reservations with few other recreational options finally forced Congress to pay attention; the National Inhalant Prevention Coalition was founded in 1992, and Congress designated a National Inhalant Abuse Prevention Week in 1995 after the death toll became impossible to ignore. Public attention spiked, funding followed for a few years, and then — because inhalants never produce a dramatic supply-chain story, a cartel, or a scheduling fight — the coverage and the funding both faded well before the underlying deaths did. Thirty years later, difluoroethane and nitrous oxide are killing people in Oregon at a documented rate, and the country is having the identical fight over identical products with a new generation of teenagers who’ve never heard of the last one.

The psychology: who reaches for it, and why it isn’t about getting high

A Preventive Medicine study out of the University of Mississippi, led by Andrew Yockey using three years of national survey data, found something that should reframe how anyone screens for this: the highest-risk group isn’t the older teens experimenting with everything else first. It’s 12- and 13-year-olds — kids too young to buy most other drugs and too young for most substance-use prevention curricula, which are usually pitched at high schoolers. And within that group, teenage girls carry the highest odds of developing an actual inhalant use disorder — repeated use to the point of dependence, not a one-time experiment.

The “why” is the part worth sitting with if you work with kids, or if you are the parent of one. Yockey’s team ties girls’ elevated risk to using inhalants as a coping mechanism — for anxiety, depression, stress, or friction with peers — the same emotional terrain that drives disordered eating or self-harm in the same age group, not the sensation-seeking framing that dominates most drug-prevention messaging aimed at boys. If your mental model of “why a kid huffs duster” is thrill-seeking, you will miss the 13-year-old girl who is doing it to turn a feeling off. That’s a screening failure with a body count, and it’s fixable the moment a pediatrician, school counselor, or parent knows to ask the coping-mechanism question instead of the thrill-seeking one.

Layered on top of that: social media didn’t invent inhalant use, but it did industrialize the pitch. Nitrous videos studied alongside the research averaged over 300,000 views with no age gate and no content warning, packaging a fatal-on-the-first-try substance with the same bright, snackable production values as a makeup tutorial. Flavored recreational nitrous brands built an entire aesthetic — candy-colored canisters, fruit flavors, club and party branding — before the FDA’s advisory and a wave of lawsuits alleging marketing to minors caught up to them. One brand, Galaxy Gas, stopped consumer sales in September 2024. The canisters, the flavors, and the aesthetic that made it popular didn’t go anywhere; they just moved to the next label.

What’s actually changing, and what isn’t

Oregon is one of the only states that has moved on this with real teeth. House Bill 3447, now state law, requires anyone selling a nitrous oxide canister to verify the buyer is 18 or older with ID — in person or online — the same standard most states already apply to spray paint and other inhalant-adjacent products precisely because minors have always found the workaround. State Sen. Lisa Reynolds, a pediatrician before she was a legislator, pushed the bill while acknowledging nitrous has legitimate culinary and industrial uses that shouldn’t be swept away — the same needle every inhalant-restriction bill has to thread, which is part of why so few states have passed one.

If you are a parent reading this and your instinct is to search the house for spray cans: that instinct isn’t wrong, but it’s incomplete. The category is enormous — cleaning products, dusters, nitrous chargers, markers, glue — and physically removing every product isn’t realistic in most homes. What actually moves the needle, per the research, is asking a different question than “are you using drugs”: ask what’s stressing them out this week, and whether they’ve heard of anyone using dusters or “whippets” to cope with it. That conversation catches the coping-mechanism pathway the thrill-seeking framing misses entirely.

For providers and school-based counselors: build the coping-mechanism screening question into intake alongside the standard substance-use questions, specifically for patients under 14 — the age band where current screening tools are least likely to ask about inhalants at all, because most were designed around an older, sensation-seeking user profile that this research says is wrong for this substance.

None of this requires waiting on a scheduling fight or a federal ban that will always lag behind whatever the next flavored canister is called. Naloxone doesn’t reverse an inhalant death — there’s no equivalent rescue drug for this category, which is its own argument for why the conversation has to happen before the first can, not after. Claudia Dimit didn’t get a warning label that meant anything. The next parent reading this still can.
