Whippets are small pressurized canisters of nitrous oxide. People inhale the gas for a short, strong high. Although the gas wears off in minutes, harm from repeated use can last and affect the nerves, spinal cord, and brain.
By 2019, almost 13 million Americans aged 12 and older had misused nitrous oxide at least once. The figure comes from the National Survey on Drug Use and Health. Despite their party-gas image, nitrous oxide whippets can cause serious harm. The medical evidence helps explain those risks and when to seek treatment for inhalant addiction.
What Are Whippets?
Whippets are small steel chargers filled with nitrous oxide, a colorless gas with a faint sweet smell. They are made for use in whipped cream dispensers. The food industry uses the gas as a foaming agent in whipped cream. In dental settings, medical professionals mix nitrous oxide with oxygen to sedate patients and provide pain relief. This medical use of nitrous oxide is brief and closely watched.
Recreational nitrous oxide use lacks those medical safeguards. The gas can still produce euphoria and dissociation for a minute or two. Global Drug Survey findings describe use among voluntary respondents and do not provide a representative estimate for the general population.
Other names and common forms include:
- Laughing gas, whip-its, and hippy crack
- Small whipped cream chargers
- Large flavored tanks sold in fruit and candy flavors
Nitrous oxide is not federally scheduled under the Controlled Substances Act, but sales and misuse are subject to other federal and state restrictions. In June 2025, the FDA renewed its warning against inhaling nitrous oxide products and named 15 brands, Galaxy Gas among them [1]. The brand story is in our post on what is galaxy gas.
How Nitrous Oxide Affects the Brain and Body
Nitrous oxide acts directly on the brain, while recreational use can also displace oxygen. With repeated exposure, it can disable vitamin B12 and damage nerves and the spinal cord.
The Short High and the Oxygen Problem
Nitrous oxide is a central nervous system depressant that slows brain activity within seconds. It can cause lightheadedness, giggles, and a sense of distance from the surroundings.
The whippet high fades within minutes, which can lead people to use it repeatedly in one sitting. This feeling of being cut off from the surroundings is called dissociation. Ketamine belongs to the same class of dissociative drugs, and our post on is ketamine addictive explores its potential for misuse.
Another major danger is oxygen deprivation, as each breath of pure gas lacks enough oxygen. This shortage can starve brain cells within minutes.
The FDA warns that inhaling these products can cause:
- Blackouts and asphyxiation, meaning suffocation
- Blood clots
- Frostbite from inhaling directly out of a freezing cold canister
- Limb weakness, paralysis, and trouble walking
- In some cases, even death
Oxygen loss also puts stress on the heart. Poison reports often note a racing or irregular heartbeat. Deaths tied to the gas in the United States rose from 23 in 2010 to 156 in 2023 [2]. A 2025 JAMA Network Open study found this increase in CDC records.
Emergency medicine teams report a similar rise in poisonings and 911 calls, with most cases involving young people and adults under 40.
How the Gas Disables Vitamin B12
Nitrous oxide disrupts the body’s vitamin B12 metabolism by changing the cobalt atom at the vitamin’s core. This change does not reverse on its own. The disabled B12 cannot support an enzyme called methionine synthase. Nerves need this enzyme to build and repair myelin, the soft coating that protects them.
The harm can build with repeated exposure as impaired B12 function disrupts nerve maintenance. Eating more B12-rich foods or taking supplements does not reliably prevent damage while nitrous oxide use continues.
Long-Term Effects of Nitrous Oxide
The long-term effects of nitrous oxide can seriously harm the brain and spinal cord. Doctors call this harm nitrous oxide toxicity. For a broader comparison with other substances, see our guide to the most addictive drugs here.
Subacute Combined Degeneration Explained
Subacute combined degeneration damages myelin inside the spinal cord, especially in the back and side columns. These areas carry signals for touch, balance, and movement. Symptoms often begin with numbness and tingling in the feet, followed by muscle weakness, poor balance, and difficulty walking. Some people also lose fine muscle control in their hands.
A 2021 case report in Cureus describes this damage along a man’s upper spinal cord after recreational use [3]. His symptoms partly improved after he stopped using the gas and began vitamin B12 shots.
Nerve, Blood, and Mental Health Damage
Beyond the spinal cord, nitrous oxide effects can include:
- Peripheral neuropathy, meaning nerve damage in the hands and feet, with weakness that hits the legs hardest
- Depressed bone marrow and abnormal blood counts
- Psychiatric symptoms such as paranoia, mood swings, and auditory hallucinations (hearing sounds that are not there)
- Cognitive impairment, the medical term for dulled thinking and memory
- Lasting brain damage after severe oxygen loss
Whippets belong to the family of inhalant drugs, which also includes flammable substances such as glue and sprays. Our post on are inhalants addictive covers the risks of other inhalant drugs and the group as a whole.
A routine blood test may show vitamin B12 levels in the normal range. However, the vitamin can still be deficient, making diagnosis harder. Levels often drop in heavy users, but a normal result does not rule out a problem. Clinicians may therefore check homocysteine and methylmalonic acid alongside other tests. A review reports elevated levels of at least one in more than 90 percent of patients with nitrous oxide-related neurological illness [4]. This figure applies to that illness rather than everyone who uses the gas.
Are Whippets Addictive?
Whippet addiction may differ from dependence on opioids or alcohol. Researchers still debate whether the gas causes true physical dependence. However, case reports clearly describe compulsive use, including daily sessions, growing amounts, and continued use despite numbness or falls.
The National Institute on Drug Abuse explains: “It is not very common, but yes, you can become addicted to inhalants” [5]. Heavy use can cause psychological dependence, a strong mental pull to keep using. Some people who stop also report withdrawal symptoms such as irritability, anxiety, and strong cravings.
Whippet addiction can be easy to miss because the gas is legal and cheap. Questions about dependence also arise with cannabis, which we discuss in our post on whether marijuana is addictive. A 2020 survey in England and Wales found that nitrous oxide was the second most used recreational drug among young adults aged 16 to 24, behind cannabis.
Signs of a Whippet Problem
Warning signs of whippet use often show up in the body first:
- Numbness or tingling in the fingers or feet
- Unsteady walking or balance problems
- A slide in mood, memory, or focus
- Escalating daily use, with sessions growing from a few canisters into dozens
- Needing a high dose to feel anything
- Unexplained spending or secrecy
People may hide nitrous oxide misuse, allowing damage to build before others notice. Other legal-seeming highs sold at gas stations and vape shops also carry risks, including synthetic cannabis sold as K2 or Spice.
Treatment for Nitrous Oxide Abuse
Treatment begins with stopping the gas and getting medical care, often including high-dose vitamin B12 shots to help nerves heal. When treatment starts early, much of the damage can be reversed.
Recovery is common, though it is not guaranteed. A 2024 narrative review reports some improvement in 95 to 97 percent of patients in the studies it discusses [4]. However, more than a third of hospitalized patients still had neurological symptoms after months of treatment, so improvement does not always mean full recovery.
When use becomes compulsive, stopping alone can be hard. Doctors treat nitrous oxide addiction as they would other substance use disorders. Care may begin with supervised detox, with addiction treatment options ranging from outpatient counseling to residential care. Behavioral therapy helps prevent relapse, while psychiatric care can address mood problems that persist.
Stopping whippets involves both breaking a compulsive use pattern and assessing medical harm. The first days of heroin withdrawal symptoms raise different care needs, but numbness, weakness, or trouble walking after nitrous oxide use also needs prompt medical attention.

Frequently Asked Questions About Nitrous Oxide Misuse
How Long Does a Whippet High Last?
A whippet high usually lasts a few minutes or less, which can encourage people to use the gas repeatedly in one sitting and increase oxygen loss. As the effects wear off, the comedown may bring a headache, dizziness, confusion, and low mood.
Is Nerve Damage From Nitrous Oxide Reversible?
Nerve damage from nitrous oxide can often be partly reversed when treatment begins early. Stopping the gas and starting vitamin B12 shots can help recovery. Most people in published studies improve, but prolonged heavy use makes lasting damage more likely.
What Happens If You Take Nitrous Oxide Every Day?
Daily use leaves the body short of working vitamin B12, allowing nerve and spinal cord damage to develop within a few months. Each session also increases the risk of fainting, falls, and oxygen loss, so daily use calls for professional treatment.
