FDA Nitrous Oxide Warning: Nerve Damage and Other Risks

Andreas Weiland 2017

Inhaling nitrous oxide for a high is not harmless. The FDA has told consumers not to inhale nitrous oxide from any canister, tank or charger, because misuse can cause vitamin B12 deficiency, nerve and spinal cord damage, loss of consciousness and, in some cases, death. Damage can show up weeks later as numbness or trouble walking.

This guide is for anyone who has used "laughing gas" recreationally, or who is worried about a friend, partner or teenager who has. It explains what the warning says, why the gas hurts nerves, and which symptoms mean you should see a doctor now.

Key takeaways

  • The FDA advises against inhaling nitrous oxide products of any size or flavor, including those sold as whipped cream propellants.
  • Heavy or regular use can drain your usable vitamin B12, which can lead to nerve damage, tingling, numbness and, in severe cases, paralysis.
  • The most immediate danger is lack of oxygen: people can pass out, suffocate or have accidents.
  • Numbness, tingling, weakness or balance problems after use need prompt medical care. Tell the doctor what you used.
  • Stopping use early, and getting checked, gives you the best chance of recovery.

What did the FDA actually say about nitrous oxide?

In March 2025 the U.S. Food and Drug Administration issued a safety alert, later updated in June 2025, telling people not to inhale nitrous oxide products. The FDA advisory covers any flavor and any size of canister, tank or charger. These products are often marketed as food-processing propellants for whipped cream, and the agency notes they are sold online, in smoke and vape shops and at gas stations.

The FDA says it has seen an increase in reports of adverse events and is continuing to track them. It does not give a case count, so be wary of social posts that quote dramatic numbers without a source. If you spot one, our guide on how health misinformation spreads and how to spot it is a useful filter.

The health effects listed in the advisory include:

  • Vitamin B12 deficiency and abnormal blood counts
  • Numbness, tingling, limb weakness, trouble walking and paralysis
  • Loss of consciousness, lightheadedness, headache and asphyxiation
  • Blood clots, palpitations and frostbite
  • Impaired bowel and bladder function
  • Psychiatric effects such as delusions, hallucinations, paranoia and depression
  • Death, in some cases

The FDA also notes that regular inhalation can lead to prolonged neurological effects, including spinal cord or brain damage, that may persist after someone stops.

Why does nitrous oxide damage nerves?

The short version: vitamin B12. Your nerves need B12 to keep their protective coating healthy, and nitrous oxide interferes with it. The NHS lists nitrous oxide alongside certain medicines as something that can lower the B12 in your body.

The UK drug advice service FRANK explains that heavy regular use can lead to B12 deficiency, and that severe deficiency can cause serious nerve damage, with tingling and numbness in the fingers and toes. That damage can be painful, can make walking difficult and, in some cases, can leave lasting paralysis.

Here's what makes it tricky. Nerve symptoms often build slowly. Someone may feel fine after a weekend of use, keep going for weeks, and only notice pins and needles or clumsy legs much later. By then the problem is already underway.

Who has less margin for error?

Anyone can be harmed, but people whose B12 is already low have less room to spare. According to the NHS, that includes people who don't regularly eat meat, fish or dairy and don't use supplements or fortified foods, people with pernicious anaemia or other conditions that affect absorption, people who've had stomach surgery, and people taking certain medicines such as metformin or acid-reducing drugs. If any of those apply to you, nitrous oxide is an even worse bet.

What are the immediate dangers?

Nerve damage is the slow risk. The fast risk is oxygen. FRANK warns that taking too much can make you fall unconscious or suffocate from lack of oxygen, and that people have died this way. Its specific safety points are worth knowing even if you never plan to use it:

  • Inhaling straight from a canister is far more dangerous. The gas comes out extremely cold and can injure the throat and lungs.
  • Large canisters make it hard to judge how much you've taken.
  • Using it in an enclosed space is very dangerous.
  • Never put a plastic bag over your head.
  • Fainting can cause falls, injuries and accidents, especially near roads, water or stairs.

Mixing it with other substances adds unpredictable risk. And driving after use is never safe.

Warning signs: when to see a doctor

Use this checklist if you, or someone you know, has used nitrous oxide recently or regularly.

What you noticeWhat to do
Someone is unconscious, not breathing normally, has collapsed or can't be wokenCall your local emergency number now. In the US, call 911.
New numbness, tingling, "pins and needles," weakness in arms or legs, or trouble walking or balancingGet seen promptly, the same day if you can. Don't wait to see if it passes.
Bladder or bowel changes, confusion, hallucinations or paranoiaSeek urgent medical care.
No symptoms, but you've used it heavily or oftenStop, and book a visit with your doctor to talk about B12 and a check of your nerves.

Be honest with the clinician about what you used and how often. A common reason these cases get missed is that nobody asks and the patient doesn't mention it. Doctors aren't there to judge you, and the detail can change which tests they run. The FDA also asks people with symptoms to contact a health care provider and to report adverse events through the agency.

Why do people use it, and what helps instead?

The high is brief, cheap and easy to get, and many people think it's the same as what a dentist gives you. It isn't. In a dental chair, the gas is mixed with oxygen and given under supervision. A balloon or canister at a party has none of those safeguards.

For some people the draw is less about fun and more about escape from stress, social anxiety or low mood. If that sounds familiar, the underlying need is real and deserves a better answer. Our guides on somatic exercises for anxiety and on how to calm nerves are a starting point. If use has become hard to stop, our piece on whether addiction cravings ever go away explains what recovery tends to look like over time.

How to talk to someone you're worried about

  1. Pick a calm, private moment, not mid-party.
  2. Lead with what you've noticed ("you mentioned your feet feel numb") rather than labels.
  3. Share the specific risk: nerve damage that can creep up slowly.
  4. Offer practical help, such as booking a doctor's appointment or going with them.
  5. Expect some pushback, and keep the door open.

FAQ

Can one time using nitrous oxide cause damage?

The clearest risks described by health agencies come from heavy or regular use, which can lead to B12 deficiency and nerve damage. But even a single session can be dangerous, because the gas can make you pass out or suffocate, and inhaling from a canister can cause cold injuries. There's no level of recreational use that health authorities describe as safe.

Is nerve damage from nitrous oxide reversible?

Sometimes, partly or fully, especially when it's caught early and the person stops using. Doctors usually test B12 and related markers and may give B12 treatment. However, the FDA notes that neurological effects, including spinal cord damage, can persist after stopping, and FRANK warns some cases lead to lasting paralysis. Getting checked quickly gives you the best odds.

Is the nitrous oxide at the dentist dangerous too?

Dental use is different. It's mixed with oxygen, given for a short time and monitored by trained staff. If you have a known B12 problem or a condition affecting B12, mention it before any procedure. The FDA warning is aimed at people inhaling nitrous oxide from canisters, tanks and chargers sold for other purposes.

What to do next

  • If you use nitrous oxide, stop now, and don't use it alone, in an enclosed space or from a canister directly.
  • If you have numbness, tingling, weakness or balance problems, book a same-day appointment and say what you used.
  • If you're struggling to stop, in the US call the free, confidential SAMHSA National Helpline at 1-800-662-4357, any time.

Muscle Gain Diet: What Actually Works, Kept Simple

Image
To build muscle, most people who lift regularly need about 1.4 to 2.0 grams of protein per kilogram of body weight a day, spread over meals of roughly 20 to 40 grams each, plus enough total food to fuel training. Add consistent strength training and decent sleep, and that covers most of the results. Everything else is fine-tuning. This guide is for anyone who has started lifting and feels buried in conflicting advice about meal timing, shakes and supplement stacks. Here's the short, evidence-based version. Key takeaways The International Society of Sports Nutrition (ISSN) says 1.4 to 2.0 g of protein per kg per day is enough for most exercising people building muscle. Spread protein across the day, about 20 to 40 g per meal, every 3 to 4 hours. Exact timing around your workout matters less than total daily intake. Eating before or after training both work. Creatine monohydrate is the best-supported supplement. Protein powder is a convenience, not a requirement. If you...

Top 10 Exercises to Help You Sleep Longer and Better

Image
The best exercises for sleep are the ones you'll do most days: brisk walking, yoga, swimming, cycling, strength training and gentle evening stretching all have research linking them to falling asleep faster and sleeping more deeply. Moderate activity can fit almost any time of day. Hard, sweaty workouts are usually best kept away from the last couple of hours before bed. This guide is for you if you lie awake at night, wake up unrefreshed, or want a drug-free way to sleep better, and you'd like to know which kind of movement to try first. Key takeaways Regular activity over weeks matters more than any single workout. Expect gradual change, not an overnight fix. Morning walks outdoors pair movement with daylight, which helps set your body clock. Slow, breath-focused practices such as yoga, tai chi and stretching are the best fit for evenings. Save high-intensity workouts for morning or early afternoon if late sessions keep you up. Exercise helps most sleep problems but...

Plant-Based Diet for Kidney Disease: Foods, Benefits, Meals

Image
A plant-based diet can suit many people with chronic kidney disease (CKD), and kidney organizations say eating more plants in place of red meat may help slow its progression. The catch is that potassium, phosphorus, protein and sodium still need managing, and your limits depend on your lab results. A renal dietitian should set them. This guide is for people living with CKD, and the family members who cook for them, who want to eat more plants without upsetting their blood work. Key takeaways The National Kidney Foundation says eating more plant-based foods in place of red meat may help prevent and slow the progression of chronic kidney disease. The body absorbs more phosphorus from animal foods than from plant foods, and phosphate additives in processed foods are almost completely absorbed. Foods with 200 mg or more of potassium per serving count as high-potassium, and that includes many fruits, vegetables, beans and nuts. Most adults should keep sodium to no more than 2,300 m...

Can Pinworms Last for Years? Why Infections Keep Coming Back

Image
No, a single pinworm can't live in your body for years. Adult worms live for only a few weeks. What makes an infection seem to last for months, or even years, is reinfection: eggs get swallowed again and start a new cycle before the old one ends. Break that cycle and the infection clears. This is for parents who've treated a child, seen the itching come back a few weeks later, and started to wonder whether something more serious is going on. Key takeaways Pinworms live for weeks, not years. Long-running "infections" are almost always repeated reinfections. Treatment is two doses of medicine, two weeks apart, because the medicine kills worms but not eggs. Everyone in the household needs treating at the same time, even people with no symptoms. Eggs can survive on bedding, clothes and surfaces for around two to three weeks, so cleaning matters as much as medicine. Pinworm rarely causes serious harm, but see a doctor for babies under 2, during pregnancy, or if t...

Plant Protein Powder for Acne-Prone Skin: What to Know

Image
If your skin broke out after you started whey protein shakes, switching to a plant-based protein powder is a reasonable experiment. Cow's milk has been linked with acne, and case reports describe acne flares that cleared after whey was stopped. A pea protein powder can support muscle growth, and one trial found results similar to whey. This guide is for people who lift or train and want to keep building muscle without guessing about their skin. It covers what the evidence does and doesn't show, how to choose a powder and how to run a fair test. Key takeaways The milk link is real but not fully explained: the American Academy of Dermatology (AAD) says studies link cow's milk with acne, though the reason isn't clear. Whey evidence is limited: it comes mostly from small case reports and observational studies, not large trials. Pea protein can build muscle: in a 12-week trial, pea and whey produced similar gains in muscle thickness. Sugar matters too: high-gly...

Soursop Benefits and Risks: Fruit, Leaves and Tea

Image
Soursop fruit is a healthy, fibre-rich tropical fruit that's safe to enjoy in normal amounts. Its leaves and tea have traditional uses with some early lab and animal evidence, but no human trials show soursop treats or cures cancer. High-dose leaf extracts and supplements also raise real concerns about nerve damage, so they deserve caution. This is for anyone who enjoys soursop, has been told to drink the leaf tea for a health problem, or has seen posts claiming it beats chemotherapy and wants a straight answer. Key takeaways The fruit pulp offers fibre, vitamin C and potassium, and fits well in a varied diet. Soursop extracts kill some cancer cells in lab dishes, but that hasn't been shown in people. No reputable cancer organisation supports it as a treatment. Compounds in soursop, especially concentrated in leaves, seeds and bark, can harm nerve cells. Heavy long-term use has been linked to Parkinson-like symptoms. Occasional leaf tea is different from daily concentr...

Calorie Deficit and Insomnia: Why Dieting Keeps You Awake

Image
Yes, a calorie deficit can cause insomnia. Eating less than you burn lowers overnight blood sugar, raises the hunger hormone ghrelin and nudges cortisol up, and together those signals can wake you at 2 or 3 a.m. The bigger and faster the deficit, the more likely your sleep suffers. This guide is for anyone who started a diet and suddenly sleeps worse. You'll learn how to recognize diet-related sleep trouble, and how to adjust your plan so you keep losing fat without lying awake staring at the ceiling. Key takeaways Diet-related sleep trouble usually looks like waking in the second half of the night, not trouble falling asleep. Large, fast deficits disrupt sleep more than small, steady ones. Keeping protein adequate and saving some carbohydrate for the evening often helps. Poor sleep makes dieting harder: it raises hunger and can shift weight loss away from fat and toward muscle. Loud snoring, gasping, or insomnia that started before the diet needs a medical check, not a ...

Fruits That Help Reduce Cholesterol and What to Avoid

Image
Avocado, berries, oranges and an apple, fruits that fit a cholesterol-friendly diet Fruits that are rich in soluble fiber, such as apples, pears, oranges, bananas and prunes, can help lower LDL ("bad") cholesterol as part of an overall heart-healthy diet. Avocado can help too when it replaces saturated fat. Fruit alone won't fix high cholesterol, but it's one of the easiest changes to stick with. This guide is for anyone who's just seen a high cholesterol result and wants to know what to put on the plate, and what to watch out for, especially if you take a statin. Key takeaways MedlinePlus lists apples, bananas, oranges, pears and prunes as fruit sources of soluble fiber, which helps lower cholesterol. The suggested target is 10 to 25 grams of soluble fiber a day, from fruit, oats, beans and other foods. In a small controlled study, a moderate-fat diet with one avocado a day lowered LDL more than a similar diet without avocado. Grapefruit, Seville ora...

No-Sugar Diet: How to Cut Added Sugar Step by Step

Image
A no-sugar diet means cutting added sugars, not the natural sugar in whole fruit, vegetables and plain dairy. You drop soda, sweets and sweetened snacks first, then hunt down hidden sugar in sauces, bread, yogurt and cereal. Most people get through the hardest cravings within one to two weeks. It sounds simple until you start reading labels and find sugar in pasta sauce, salad dressing and "healthy" granola. This guide is for anyone who wants to cut back without a miserable, all-or-nothing approach that collapses by week two. Key takeaways The target is added and free sugars: table sugar, syrups, honey, fruit juice and sweeteners added to processed food. The WHO advises keeping free sugars under 10% of daily calories, with extra benefit below 5%, about 25 grams or 6 teaspoons a day. The CDC reports that US adults average about 17 teaspoons of added sugar a day. Expect cravings, irritability or low energy for the first few days; they usually ease within one to two we...

Why Am I Losing Muscle Mass? Causes, Signs and Fixes

Image
Most unexplained muscle loss comes from using your muscles less, getting older, or eating too little protein and energy. Less often, it's a sign of nerve damage, a hormone problem or another illness. The good news is that the common causes respond well to regular strength training and enough protein at each meal. Maybe your legs look thinner after a few months at a desk job, or the stairs feel harder than they did last year. This guide is for anyone who has noticed that change and wants to know what's behind it and what to do next. Key takeaways Disuse is the most common cause: muscles shrink when they aren't worked regularly, and this type can often be reversed with exercise and better nutrition. Age plays a part: Cleveland Clinic says age-related muscle loss (sarcopenia) starts in your 30s or 40s and speeds up between ages 65 and 80. Strength training is the main fix: adults should do muscle-strengthening activity on at least 2 days a week, according to the CD...
