The Food and Drug Administration advises consumers not to inhale nitrous oxide products from any size canisters, tanks, or chargers [1]. That advisory is the plainest federal statement on this subject, and it was updated twice in 2025 [1].
The reason it exists is not the high. It is what regular inhaling does to nerves. The FDA says that for some individuals who regularly inhale nitrous oxide, the habit can lead to prolonged neurological effects, including spinal cord or brain damage, even after stopping use [1].
If you are reading this because your hands or feet have started to tingle, that is the part to act on. It is a reason to see a clinician now.
This page covers what nitrous oxide is, what the FDA advisory says, the short-term dangers, the nerve and blood problems, why a nitrous oxide emergency is not an opioid emergency, who uses it, what stopping involves, and what treatment looks like. Our page on inhalants covers the wider class, and our drug addiction hub covers the rest.
What Nitrous Oxide Is and Where It Comes From
It is a gas with two ordinary jobs and one dangerous misuse.
The federal food regulation describes it plainly. Nitrous oxide is also known as dinitrogen monoxide or laughing gas, and it is a colorless gas, about 50 percent heavier than air, with a slightly sweet smell [2]. The same regulation affirms it as generally recognized as safe as a direct human food ingredient, used as a propellant, aerating agent and gas [2].
Read that carefully, because it is the sentence people misread. It is a food rule about what may go into a whipped cream dispenser. It says nothing about breathing the contents, and the FDA’s advisory is the agency’s statement on that [1].
The National Institute on Drug Abuse groups nitrous oxide with the inhalant gases, alongside anesthetics such as ether and halothane, and notes it is often called laughing gas [3]. NIDA also records how it reaches people: it is sold in small vials known as whippets or chargers [3].
What the FDA Advisory Actually Says
It is short, and every clause in it is doing work.
The FDA advises consumers not to inhale nitrous oxide products from any size canisters, tanks, or chargers [1]. It notes that these products are marketed as both unflavored and flavored canisters and are sold as a food processing propellant for whipped cream and culinary food use [1]. And it states that intentional misuse or inhalation of contents can lead to serious adverse health events, including death [1].
The advisory also explains why it was written. The FDA says it has observed an increase in reports of adverse events after inhalation of nitrous oxide products [1]. It first warned in March 2025 and updated the notice in June 2025 to add more brand names [1].
Those brand names are worth knowing if you have found a canister and do not recognize it. The FDA’s list includes Galaxy Gas, Whip-it!, Cosmic Gas, Baking Bad and Monster Gas, and the agency says the list is not exhaustive [1]. Its advice to anyone who has already used these products and is worried is to contact a health care provider [1].
The Short-Term Effects, and How People Get Hurt Quickly
The immediate dangers are mechanical as much as chemical.
The FDA’s list of reported effects includes lightheadedness, headache, palpitations, loss of consciousness, asphyxiation and frostbite [1]. Frostbite is on that list because the gas leaves a pressurized container extremely cold. Asphyxiation is on it because a lungful of gas is a lungful that is not air.
MedlinePlus puts the worst case in one sentence. Using inhalants, even once, could lead to an overdose, which can cause you to have seizures or your heart to stop, and it can be deadly [4]. NIDA says the same thing from the other direction: the toxic chemicals in inhalants and the way people use them can cause a person to stop breathing, and these fatal effects can happen even when a person uses inhalants just one time [3].
If someone is having a seizure, is unresponsive or has trouble breathing, call 911. For a mental-health crisis call or text 988.
The blood counts matter too, and they are easy to miss. Abnormal blood counts and blood clots are both on the FDA’s list of reported effects [1].

Nerve Damage, Vitamin B12 and Why Numbness Is the Warning Sign
This is the section that changes what people do, so it is worth reading slowly.
The FDA’s list of reported effects runs through the nervous system from one end to the other: vitamin B12 deficiency, numbness, tingling, limb weakness, trouble walking, paralysis, and impaired bowel and bladder function [1]. Psychiatric disturbances are on the same list, and the FDA names delusions, hallucinations, paranoia and depression [1].
Then comes the sentence that matters most. For some individuals who regularly inhale nitrous oxide, this habit can lead to prolonged neurological effects, including spinal cord or brain damage, even after stopping use [1].
NIDA says the same thing about inhalants as a class. Perhaps the most significant toxic effect of long-term exposure to inhalants is damage to the brain and other parts of the nervous system [3]. MedlinePlus lists loss of coordination, spasms in the arms and legs and brain damage among the long-term effects [4].
So the practical rule is simple. Tingling or numbness in the hands or feet, weakness, or a change in how you walk are reasons to be seen by a clinician quickly, not reasons to wait and watch. The FDA’s own instruction is to contact a health care provider if you have recently used these products and are concerned about your health [1]. What to do about a B12 result belongs to whoever runs the test, and this page publishes no supplement plan of its own.
Why a Nitrous Oxide Emergency Is Not an Opioid Emergency
This part gets confused often enough that it is worth stating in full.
Naloxone is a life-saving medication that can reverse an overdose from opioids, including fentanyl, heroin and prescription opioid medications, when given in time [5]. Nitrous oxide is an inhaled gas, and it is not an opioid, so naloxone is not the treatment for what it does.
That is not the end of the answer, though, and the CDC supplies the rest of it. Naloxone will not harm someone if they are overdosing on drugs other than opioids, so the CDC says it is always best to use it if you think someone is overdosing [5]. The CDC also says that if you cannot tell whether a person is high or overdosing, treat it like an overdose [6].
Put those together and the instruction for a bystander is clear. Call 911 [6]. If naloxone is there and you do not know what the person took, use it [5]. Keep the person awake and breathing, lay them on their side to prevent choking, and stay with them until emergency assistance arrives [6].
If someone is having a seizure, is unresponsive or has trouble breathing, call 911. For a mental-health crisis call or text 988.
Who Is Using It, and What the Numbers Do and Do Not Show
The federal survey data is about inhalants as a class, and that limit should be stated rather than hidden.
NIDA reports that the rate of inhalant use has been generally declining in the United States in the past two decades [3]. In 2023, less than 1% of people aged 12 and older reported using inhalants at least once in the past year [3]. Among 8th graders, around 4% had used inhalants in the last year, according to the Monitoring the Future survey [3]. And about 0.1% of people who use inhalants, over 300,000 people, reported having an inhalant use disorder in the past 12 months [3].
None of those figures is a nitrous oxide figure. They cover solvents, aerosols, gases and nitrites together [3]. Set against them is the FDA’s observation that reports of adverse events after inhaling nitrous oxide products have increased [1]. A falling class-wide trend and a rising product-specific signal are not a contradiction. They are two different measurements.
Dependence, Stopping and What Withdrawal Looks Like
People do get stuck on it, and the honest framing keeps the sources’ hedges.
NIDA reports that many people who use inhalants report a strong need to continue using them even if they wish to stop, particularly those who have used them for long periods or over many days [3]. It adds that regular use of inhalants can lead to symptoms of withdrawal after a person stops, including irritability, anxiety and drug craving [3].
MedlinePlus is more reassuring and equally specific. Addiction to inhalants is rare, but it can happen if you use them repeatedly, and stopping them can cause withdrawal symptoms such as nausea, sweating, trouble sleeping and mood changes [4]. “Rare” is the source’s own word and it stays.
No federal source publishes a nitrous oxide withdrawal timeline, so this page does not print one. Our page on withdrawal symptoms covers the general picture across substances. What the absence of a timeline should not do is delay a call, because the medical questions here are about nerves and blood rather than about getting through a few rough days.
Getting Assessed, and What Treatment Involves
Start with a clinician rather than with a program, because the first questions are medical.
An assessment for this looks at the neurological signs, a vitamin B12 result and a blood count, alongside the usual questions about how much, how long and what else is in the picture. Those findings shape everything that follows. Our page on what the treatment process is like covers the order it usually runs in.
On the addiction side, MedlinePlus is direct: behavioral therapy may help people who are addicted to inhalants [4]. No medication is approved for inhalant use disorder, which is a fact about what exists rather than a verdict on whether help works. Our page on therapy approaches used in treatment explains what those sessions involve.
Two other threads come up often. The FDA lists psychiatric disturbances including depression among the reported effects [1], so dual diagnosis treatment is frequently the right shape of care. And getting through the acute phase is a beginning rather than an end: SAMHSA states that detoxification is not substance abuse treatment and rehabilitation [7].
Medical detox is a level of care in its own right. Some people go on to residential rehab, others to an outpatient program, and our explainer on the levels of care sets out what each one involves. Our guide to getting into rehab covers the order the calls happen in, our treatment centers lists our campuses by state, and if money is the obstacle, see what rehab costs and whether insurance covers it.
Frequently Asked Questions
What is nitrous oxide and why do people inhale it? Nitrous oxide is a colorless gas, also known as dinitrogen monoxide or laughing gas. It is affirmed as generally recognized as safe as a food ingredient used as a propellant and aerating agent, which is a food rule rather than a verdict on inhaling it. NIDA groups it with the inhalant gases and notes it is sold in small vials known as whippets or chargers. The FDA advises consumers not to inhale these products.
Is inhaling nitrous oxide dangerous? Yes. The FDA says intentional misuse or inhalation of the contents can lead to serious adverse health events, including death. Reported effects include asphyxiation, frostbite, loss of consciousness, palpitations and abnormal blood counts. MedlinePlus says using inhalants even once could lead to an overdose, which can cause seizures or the heart to stop, and can be deadly. If someone is unresponsive or has trouble breathing, call 911.
Does naloxone reverse a nitrous oxide overdose? No. Naloxone reverses an overdose from opioids, and nitrous oxide is an inhaled gas rather than an opioid. That said, the CDC states naloxone will not harm someone overdosing on drugs other than opioids, so it is always best to use it if you think someone is overdosing. Call 911 first, give naloxone if it is there and you do not know what was taken, and stay with the person. For a mental-health crisis, call or text 988.
Can inhaling nitrous oxide cause permanent nerve damage? It can. The FDA states that for some individuals who regularly inhale nitrous oxide, the habit can lead to prolonged neurological effects, including spinal cord or brain damage, even after stopping use. Its list of reported effects includes vitamin B12 deficiency, numbness, tingling, limb weakness, trouble walking and paralysis. Numbness or tingling in the hands or feet is a reason to see a clinician quickly.
How is nitrous oxide misuse treated? It starts with a medical assessment, because the nerve and blood findings come first. MedlinePlus says behavioral therapy may help people who are addicted to inhalants. No medication is approved for inhalant use disorder. Where a mood or psychiatric problem sits alongside it, both get treated together. SAMHSA notes that detoxification is not substance abuse treatment and rehabilitation, so ask what follows it.
