According to a 2019 survey, almost 13 million Americans aged 12 or older have misused nitrous oxide in their lifetime. Also known by slang terms like 'whippets' and 'laughing gas,' understanding exactly what is the street drug nitrous is crucial due to its rising recreational use and potential for serious health consequences.

Quick Summary

The street drug nitrous is the inhalant nitrous oxide, often misused from culinary whipped cream chargers. This practice produces a short-lived euphoric high but carries significant risks, including severe vitamin B12 depletion, neurological damage, and asphyxiation.

Key Points

Source and Slang: The street drug nitrous is nitrous oxide ($N_2O$), commonly inhaled recreationally from "whippets," which are cartridges used for whipped cream dispensers.
Immediate Effects: Inhaling nitrous causes a short-lived, euphoric high, distorted perception, and giddiness, but can also cause dizziness, confusion, and accidental injuries.
Oxygen Deprivation: Recreational use can lead to asphyxiation and brain damage because the inhalation displaces breathable oxygen, especially in high concentrations or enclosed spaces.
Vitamin B12 Inactivation: Chronic and heavy use inactivates vitamin B12, a vital nutrient for nerve health, leading to a functional deficiency and severe neurological damage.
Neurological Damage: Long-term consequences include peripheral neuropathy (tingling, numbness), gait problems, muscle weakness, and, in severe cases, irreversible spinal cord damage.
Increased Risk with Heavy Use: The availability of larger canisters and flavored products has fueled heavy, frequent use, increasing the risk for severe health effects.
Medical vs. Recreational: Unlike controlled medical use, recreational inhalation is unsupervised, lacks supplemental oxygen, and carries a high risk for serious adverse effects.

What is the street drug nitrous?

The street drug known as “nitrous” is actually nitrous oxide ($N_2O$), a colorless gas with a faintly sweet odor and taste. While it has legitimate uses in medicine and food preparation, it is widely misused as a recreational inhalant, particularly among adolescents and young adults. Nitrous oxide is classified as a dissociative anesthetic, and its recreational effects, like euphoria and distorted perception, are both rapid and short-lived. This quick but intense high often encourages users to inhale the substance multiple times during a single session, significantly increasing the potential for harm.

Street users typically obtain nitrous oxide from small, pressurized steel cartridges designed for whipped cream dispensers, which are colloquially known as "whippets". Larger tanks of the gas are also increasingly available from vape shops and online retailers. The gas is often discharged into a balloon and then inhaled to warm it up, as inhaling directly from the cold pressurized canister can cause severe frostbite to the mouth, throat, and lungs. Other street names for the drug include "nangs," "hippy crack," "buzz bomb," and "balloons".

The pharmacology and acute effects of nitrous

The effects of nitrous oxide occur because the gas rapidly enters the bloodstream through the lungs and reaches the brain within seconds. In the brain, it acts as a noncompetitive antagonist of N-methyl-D-aspartate (NMDA) receptors and an agonist of GABA-A receptors, which produces its anesthetic and euphoric effects. It can also trigger the release of endogenous opioids, contributing to feelings of well-being. The high is intense but generally lasts for only a minute or two.

Short-term effects and dangers

Beyond the desired euphoria and giddiness, inhaling nitrous oxide can lead to several dangerous short-term side effects. Inhalation of the gas displaces oxygen in the lungs, which can cause oxygen deprivation, or hypoxia, in the brain. The risks escalate with high doses or in enclosed, unventilated spaces, and can even be fatal. Other immediate side effects include:

Dizziness and light-headedness
Disorientation and confusion
Lack of coordination
Blurred vision
Numbness or tingling
Nausea and headaches
Fainting

Accidents and injuries from falls are common due to the disorientation and motor impairment caused by the drug. Combining nitrous with alcohol or other substances further increases these risks.

Chronic use and long-term neurological damage

The most severe and insidious danger of heavy or repeated nitrous oxide use is the potential for permanent neurological damage. This occurs because nitrous oxide irreversibly oxidizes the cobalt atom in vitamin B12 (cobalamin), rendering the vitamin inactive. Vitamin B12 is essential for nerve health, and its inactivation can lead to a functional deficiency.

This deficiency disrupts the synthesis of the myelin sheath that insulates and protects nerve fibers in the brain and spinal cord. The resulting nerve damage, known as subacute combined degeneration of the spinal cord and peripheral neuropathy, can manifest with the following long-term effects:

Persistent numbness and tingling (paresthesia) in the hands and feet
Significant muscle weakness and spasms
Difficulty walking, poor balance, and unsteady gait
Memory loss and cognitive impairment
Psychiatric issues like psychosis, delusions, or depression

While some symptoms can improve with immediate cessation of use and high-dose vitamin B12 injections, recovery is often protracted and sometimes incomplete. Recent reports also link chronic nitrous oxide abuse to an increased risk of venous thromboembolism (blood clots) due to elevated homocysteine levels, another consequence of vitamin B12 deficiency.

Recreational vs. medical nitrous oxide: A key difference

Crucially, the risks associated with the street drug nitrous are amplified by its unsupervised, uncontrolled nature, which is in stark contrast to its safe use in a medical setting. This distinction is vital for understanding why one is dangerous and the other is a controlled anesthetic.


Feature	Recreational Nitrous Use	Medical Nitrous Use
Source	Whipped cream canisters, large tanks from retailers, online sellers.	High-purity medical-grade gas from controlled suppliers.
Administration	Inhaled directly from a balloon or dispenser, risking frostbite and hypoxia.	Administered with a secure mask and a consistent mix of 30-70% oxygen.
Purity	Can contain impurities from industrial processes; often 100% nitrous oxide.	Strict purification process for guaranteed high purity.
Supervision	No medical oversight; users are unaware of appropriate dosage or safety protocols.	Administered and monitored by a trained medical professional in a clinical setting.
Duration	Repeated, high-dose use over a short time to sustain a brief high.	Controlled, limited duration to manage pain or anxiety during a procedure.

Public health response and signs of abuse

The rising rates of nitrous oxide misuse have prompted warnings from public health authorities, including the FDA, which advises consumers not to inhale these products. There has been a concerning increase in the availability of flavored, oversized nitrous oxide canisters, which many perceive as safer, though they carry the same risks.

Recognizing the signs of nitrous abuse is important for prevention and intervention. These signs include:

Physical evidence: Finding discarded small metal "whippet" canisters or balloons, especially in high volumes.
Unusual smells: A sweet, faint odor of gas on a person's breath or clothing.
Physical symptoms: Persistent numbness or tingling in the extremities, unsteady walking, fatigue, and weakness.
Behavioral changes: Increased social withdrawal, financial problems from purchasing the drug, or continued use despite negative consequences.

Conclusion: No laughing matter

While often dismissed as a harmless "laughing gas," the street drug nitrous oxide poses serious and potentially devastating health risks, particularly with chronic and heavy use. The ease of access, combined with a misconception of its safety, has contributed to a public health concern that demands greater awareness. The neurological and psychological damage from functional vitamin B12 deficiency is a severe complication that can have lasting consequences, highlighting the stark difference between controlled medical application and dangerous recreational misuse. Education and early intervention are critical to help those struggling with nitrous oxide abuse seek treatment before irreversible harm occurs.

Frequently Asked Questions

'Whippets,' also spelled 'whippits' or 'whip-its,' are the slang term for the small, metal cartridges containing nitrous oxide ($N_2O$) used as a propellant for whipped cream. They are often misused by recreational users to inhale the gas for a brief high.

The high from inhaling nitrous oxide is very short-lived, typically lasting only a minute or two. This brief duration often leads users to inhale the substance multiple times in one session to prolong the effects.

The most dangerous effect of chronic or heavy nitrous use is permanent neurological damage. This occurs because the gas inactivates vitamin B12, leading to nerve damage, spinal cord degeneration, and other severe, long-term health issues.

Yes, death from inhaling nitrous oxide is possible, though rare. It is most often caused by asphyxiation (suffocation) due to the gas displacing oxygen in the lungs and causing fatal hypoxia, particularly when inhaled in an enclosed space or with a bag over the head.

Medical nitrous oxide is safely administered in a controlled setting by professionals, mixed with a guaranteed percentage of oxygen (typically 30-70%) to prevent hypoxia. The street version is often 100% nitrous oxide, contains industrial impurities, and is used without medical supervision or supplemental oxygen.

Signs of nitrous oxide abuse include finding discarded whippet canisters or balloons, an unusual sweet chemical odor, unexplained dizziness or confusion, numbness or tingling in the extremities, or an unsteady gait.

While not considered physically addictive in the same way as some other drugs, repeated use of nitrous oxide can lead to psychological dependence. Some heavy users report cravings, irritability, and anxiety when they stop using the drug.
