You've probably seen the little silver canisters littering the sidewalk outside a concert or a house party. They look like something out of a soda fountain, which, honestly, is exactly what they are. These are chargers for whipped cream dispensers, but in the context of a Saturday night, they aren't being used for dessert. People call them "whippets" (or whip-its). It's a quick, dizzying high that lasts about as long as a TikTok video, but there is a massive amount of misinformation floating around about what is actually happening to your brain when you inhale that gas.
Nitrous oxide (N2O) isn't new. It’s been around since the late 1700s. Back then, "Laughing Gas" parties were a legitimate upper-class social event before doctors realized the stuff was actually great for dulling pain during surgery. Today, the medical world still uses it, and the culinary world uses it to make foam. But when someone asks how to do whippets, they are usually looking for a shortcut to a dissociative state.
It feels like a vibration. A "wah-wah" sound in the ears. A total loss of motor control for about 30 seconds. But that fleeting feeling comes with some pretty heavy biological baggage that most casual users completely ignore until their hands start tingling or they can't walk straight.
The Mechanics of How People Use Nitrous Oxide
The process is technically simple, which is why it's so common. People use a "cracker" or a whipped cream dispenser (a "siphon"). The cracker is a small metal device designed to puncture the seal of the pressurized N2O canister. Because the gas is under immense pressure, it comes out freezing cold—cold enough to give you instant frostbite on your lungs or throat if you inhaled it directly from the nozzle.
To avoid literal ice burns, users discharge the gas into a balloon. This allows the gas to warm up to room temperature and lowers the pressure before inhalation. You'll see people clutching a balloon, taking a deep breath, holding it, and then exhaling back into the balloon or out into the room.
It's a "clean" high in the sense that it leaves the system quickly. However, that's a bit of a trap. Because it's so short-lived, people often do "back-to-back" chargers. They’ll go through a box of 24 or 50 in a single sitting. That’s where the real danger starts to manifest. It’s not necessarily the gas itself that is the primary killer in the short term; it’s the displacement of oxygen. When you fill your lungs with N2O, you aren't filling them with oxygen. You are essentially holding your breath while forcing a dissociative anesthetic into your bloodstream.

What's Actually Happening in Your Brain?
Nitrous oxide is a dissociative anesthetic. It works by blocking NMDA receptors while simultaneously stimulating the release of endogenous opioids and dopamine. It basically puts a barrier between your conscious mind and your sensory input. That’s why you feel "floaty."
But here is the part that gets glossed over in Reddit threads: Nitrous oxide effectively "shuts off" your body's ability to use Vitamin B12. It’s not just that it lowers your levels; it inactivates the B12 already in your system by oxidizing the cobalt atom in the B12 molecule.
Why does that matter? Because B12 is the primary ingredient your body needs to maintain the myelin sheath. Think of the myelin sheath as the plastic insulation on an electrical wire. Your nerves are the wires. Without the insulation, the signals short-circuit. This leads to a condition called Subacute Combined Degeneration of the spinal cord. It starts with a weird tingling in the fingers (paresthesia) and can end with you being unable to walk or control your bladder. This isn't some "scare tactic" from a D.A.R.E. poster; it's a documented medical reality seen in emergency rooms every single week.
The Risk of Asphyxiation and "Fishing Out"
In the world of recreational drug use, there's a term called "fishing out." This happens when someone takes enough nitrous oxide that they lose consciousness and start convulsing or twitching. To an observer, it looks like a seizure. To the person experiencing it, they usually remember nothing.
This happens because of hypoxia—lack of oxygen to the brain. If you're standing up when this happens, you're going to hit the floor. Hard. Head injuries are one of the most common "side effects" of doing whippets. People fall into coffee tables, concrete, or down stairs because their legs simply stop working for five seconds.

There is also the risk of "death by plastic bag." It sounds morbid because it is. Some users try to get a more "intense" high by putting a bag over their head to trap the gas. If you pass out while that bag is over your head, you die. It’s that simple. There is no "autopilot" that will pull the bag off for you once you're unconscious.
Why Quality Matters (And Why It’s Usually Bad)
The nitrous oxide found in food-grade chargers isn't meant for human lungs. It’s meant for whipped cream. Manufacturers often coat the inside of those silver canisters with industrial oils to prevent rust and facilitate the manufacturing process. When you "crack" a whippet, you are often inhaling aerosolized machine oil.
If you’ve ever looked at the inside of a balloon after it's been used for whippets, you might see a dark, greasy residue. That is what you’re putting into your alveoli. Over time, this can lead to lipid pneumonia or chronic lung irritation.
Then there’s the "tank" vs "charger" debate. In recent years, larger cylinders (like FastGas or Exotic Whip) have become popular. These contain way more gas than the small 8g chargers. The problem here is the sheer volume. It makes it much easier to enter a "binge" state where you are inhaling N2O for hours on end, never allowing your B12 levels to recover or your brain to fully re-oxygenate.
Real-World Consequences: The Case of B12 Deficiency
Let’s talk about a specific case. In 2022, a study published in the BC Medical Journal detailed a young man who presented with "progressive leg weakness." He had been doing whippets regularly. By the time he got to the hospital, he couldn't walk without assistance. His B12 levels appeared "normal" on a standard blood test, which is the scary part—the B12 was there, but it was inactive.

Doctors had to treat him with high-dose B12 injections for weeks. Some people recover fully. Some people end up with permanent nerve damage that leaves them with a limp or chronic pain for the rest of their lives. If you find yourself doing whippets and you notice your toes or fingers feel "fuzzy" or "numb," you need to stop immediately. Not "taper off." Stop.
How to Stay Safe (If You’re Going to Do It Anyway)
If you are determined to use nitrous oxide, there are ways to mitigate the risks, though "safe" is a relative term here.
- Breathe Oxygen: Never, ever use a mask or a bag. Take a few deep breaths of actual air between every single inhalation of gas. Your brain needs oxygen more than it needs the high.
- Sit Down: Do not do whippets while standing. You will fall. You will likely hit your head. Sit on a couch or the floor.
- Supplementation is Not a Cure: Taking B12 pills while doing whippets doesn't work. The gas stops your body from processing the vitamin. You have to stop using the gas for at least 3-4 days for your body to be able to use B12 again.
- Filter the Gas: Some people put a piece of cloth or a cotton ball inside the "cracker" or over the nozzle to catch the industrial oils. It's not perfect, but it's better than coating your lungs in machine grease.
- Don't Mix with Alcohol: Alcohol and nitrous both depress your central nervous system. Mixing them increases the chance of you vomiting while unconscious, which is a leading cause of accidental death (asphyxiation on vomit).
Identifying the Signs of Addiction
Wait, can you get addicted to "laughing gas"? Chemically, it's not the same as heroin or nicotine. But psychologically? Absolutely. The high is so short that it creates a "loop" behavior. You do one, feel great, feel the "drop," and immediately want to do another to get back to that peak.
If you find yourself spending money you don't have on "tanks," or if your room is littered with hundreds of silver canisters, you’ve moved past "casual use." The psychological pull can be intense because the "hangover" is almost non-existent in the short term, which tricks your brain into thinking there’s no price to pay.
Actionable Steps for Harm Reduction
If you or someone you know is using whippets, here is the immediate checklist for staying out of the emergency room:
- Check for "Pins and Needles": If you feel tingling in your extremities, stop using nitrous oxide immediately. This is the first sign of nerve damage.
- Take Breaks: Don't do whippets every day. Your body needs days of "clean time" to restore its B12 metabolism. Binging once a month is vastly less damaging than doing one or two every single day.
- Eat B12-Rich Foods: After a session, wait 24 hours and then load up on eggs, beef, or fortified cereals.
- Dispose of Canisters Properly: Don't be the person who leaves them in the park. They are steel; they can be recycled.
- Seek Medical Help Early: If you experience weakness in your legs, go to a doctor and be honest. Tell them you’ve been using nitrous oxide. They need to know to check for functional B12 deficiency, not just total B12 levels.
Nitrous oxide is often treated as a "joke" drug because of its association with whipped cream and the dentist. But the physiology of how it interacts with your spinal cord is anything but funny. Understand the chemistry before you put the balloon to your lips.
