Known as “laughing gas,” nitrous oxide is sold legally at gas stations, smoke shops and online retailers, and its misuse is quietly leaving young people with permanent neurological damage.

What Happened to Lu

The woman, identified only as Lu, revealed in an interview with the Australian program A Current Affair that her dependency on nitrous oxide escalated rapidly until she was consuming between 1,200 and 2,400 small aluminum canisters per day.

Lu described losing all motor function at the height of her addiction: “I couldn’t flip a pancake, I couldn’t grip a fork, I couldn’t walk. I was army crawling around my house, like dragging myself, because I couldn’t move my legs.”

Her condition has been linked to permanent spinal cord injuries, with nitrous oxide abuse known to cause severe neurological damage, including nerve deterioration and spinal degeneration. She also reported experiencing psychosis and hallucinations as her addiction deepened.

Why Nitrous Oxide Is So Accessible

Nitrous oxide has legitimate uses across multiple industries, as a sedative in medical and dental settings and as a propellant in whipped cream dispensers, and small canisters are widely sold online and in retail stores. That accessibility is a core part of the problem.

In the United States, the number of nitrous oxide poisoning cases rose from 28 in 2003 to more than 400 in 2024. Brightly colored, flavor-infused canisters are marketed on social media platforms and sold under brand names that bear little resemblance to a medical product.

The FDA warns that repeated inhalation can result in blood clots, frostbite, paralysis and brain damage. Yet in many states, there are no age restrictions or purchase limits on the product.

How Nitrous Oxide Damages the Body

Nitrous oxide interferes with the body’s ability to absorb and use vitamin B-12. Without adequate B-12, the nervous system cannot send and receive signals normally, which can result in numbness, tingling and paralysis, effects that may become permanent with heavy use.

Lu’s case is not isolated. A former professional pilot admitted to the University of Florida’s addiction treatment center was left irreversibly paralyzed after months of nitrous oxide abuse, according to Dr. Kent Mathias, director of the UF Health Florida Recovery Center.

An Oregon man named David Warwick described developing lesions up and down his spine after a year of heavy use, saying he initially turned to the drug to cope with work stress and difficult emotions. The short duration of each high, roughly 15 minutes, accelerates compulsive use patterns.

The Regulatory Gap Fueling the Crisis

Louisiana became the first U.S. state to ban retail sale of nitrous oxide in 2024, while Oregon passed a law in June 2025 requiring buyers to be 18 or older. Arizona and Ohio have enacted similar age-restriction measures, but federal oversight remains limited.

Dr. Mathias has called on the FDA to regulate nitrous oxide’s distribution the same way it controls other restricted medications, warning that “without that, this problem will continue to get worse.”

In Australia, where Lu’s story originated, regulation varies by state. The Therapeutic Goods Administration has stated that monitoring and enforcement of nitrous oxide controls falls to individual states and territories, not the federal government.

What This Means for Treatment Seekers

Nitrous oxide addiction often goes unrecognized as a substance use disorder, by families, physicians and sometimes patients themselves.

Because the product is legal and inexpensive, people may not realize their use has crossed into dependency until severe physical damage has already occurred.

Treatment for nitrous oxide addiction typically involves medical evaluation for neurological damage, nutritional intervention (particularly B-12 supplementation), and behavioral addiction treatment addressing the underlying patterns that drove compulsive use.

If you or someone you love has been using nitrous oxide heavily, speaking with a physician and an addiction specialist promptly is critical. Early intervention can limit long-term neurological harm.

Finding the Right Rehab

Substance use disorders involving legal or over-the-counter products are treatable, but they require the same evidence-based care as any other addiction.

Rehab centers experienced in inhalant and substance use disorders can provide medically supervised evaluation, co-occurring mental health support, and individualized recovery planning.

Steps to take now:

  1. Speak with a treatment advisor about programs equipped to address inhalant or non-traditional substance use disorders
  2. Ask about medical detox and neurological assessment at intake
  3. Verify that a facility uses evidence-based therapies and addresses co-occurring conditions like anxiety or depression, which commonly underlie inhalant use
  4. Understand your insurance coverage for rehab, many plans cover inpatient and outpatient addiction treatment
