Galaxy Gas is a brand of nitrous oxide chargers sold primarily for making whipped cream and other culinary foams. The small canisters contain pressurized nitrous oxide (N₂O), the same gas used in whipped cream dispensers at coffee shops and restaurants. While that’s the product’s intended purpose, Galaxy Gas has gained widespread attention because of recreational misuse, particularly among young people who inhale the gas for a brief high.
How It Works in the Kitchen
Nitrous oxide chargers like Galaxy Gas are designed to be used with a handheld device called a cream whipper. You load heavy cream into the dispenser, puncture a charger, and the gas dissolves into the fat in the cream. When you press the lever, the cream comes out as a light, fluffy foam. This works because nitrous oxide dissolves easily in fat without causing the cream to oxidize or spoil, which makes it ideal compared to other gases.
Beyond whipped cream, professional kitchens use the same chargers to create flavored foams for cocktails and desserts, to rapidly infuse liquids with herbs or spices, and to aerate mousses and sauces. The gas itself is tasteless, though Galaxy Gas sells flavored versions, which is part of what has drawn criticism. Those flavors have no culinary benefit and appear designed to make the product more appealing to inhale.
Why People Inhale It
Inhaling nitrous oxide produces a short-lived feeling of lightheadedness and euphoria, typically lasting under a minute. This practice, sometimes called “doing whippets,” has existed for decades with standard whipped cream cans, but Galaxy Gas has become especially popular on social media due to its colorful branding and flavored varieties. The product is widely available in convenience stores, smoke shops, and from online retailers, making it easy to purchase without any age verification in many states.
The FDA has issued a direct advisory telling consumers not to inhale nitrous oxide products, stating that intentional misuse or inhalation of the contents can lead to serious health events, including death.
Short-Term Health Risks
Inhaling nitrous oxide displaces oxygen. Your brain is temporarily starved of air, which is actually responsible for much of the “high” people feel. This oxygen deprivation can cause fainting, falls, seizures, and dangerous heart rhythms. The pressurized gas is also extremely cold when released, which can cause frostbite injuries to the lips, mouth, and throat.
Other acute effects reported in emergency departments include vomiting (with the risk of choking if unconscious), confusion, hallucinations, and lung injuries from the pressure of the gas. Because the high is so brief, people often use multiple canisters in a short period, which increases the risk of losing consciousness and suffocating.
What Happens With Repeated Use
The longer-term danger of nitrous oxide is less obvious but potentially more devastating. Nitrous oxide interferes with your body’s ability to use vitamin B12, a nutrient essential for maintaining the protective coating around your nerves, called the myelin sheath. Without functional B12, that coating breaks down.
The results can be severe. A case documented by Yale School of Medicine described a patient with chronic nitrous oxide use who developed numbness, weakness, and difficulty walking. An MRI revealed damage to the sensory pathways in his spinal cord. This condition, called subacute combined degeneration, is the same type of nerve damage seen in people with extreme B12 deficiency. The difference is that in nitrous oxide users, B12 levels in the blood may appear normal because the gas doesn’t reduce B12 stores. It simply renders the vitamin inactive.
The FDA notes that for people who regularly inhale nitrous oxide, the habit can lead to prolonged neurological effects including spinal cord or brain damage, even after they stop using it. Other documented consequences of chronic use include blood clots, paralysis, psychiatric disturbances like paranoia and psychosis, and impaired bladder and bowel function. Yale researchers found that these effects are often reversible with early treatment, but the key word is early. The longer the damage goes untreated, the less likely a full recovery becomes.
Legal Status and Restrictions
Nitrous oxide chargers are legal to sell in the United States because they have legitimate uses in food preparation, dentistry, and automotive applications. However, the gap between legal sale and harmful misuse has prompted a growing number of states and local governments to act. In Washington state, legislators have introduced bills to ban retail sales of nitrous oxide while exempting medical, dental, culinary, and automotive uses. The Suquamish Tribe has updated its laws to explicitly prohibit misuse of nitrous oxide, specifically targeting flavored products marketed toward young people.
Some food-grade nitrous oxide products now contain bittering agents to discourage inhalation, though this is not universal. Galaxy Gas’s flavored varieties work in the opposite direction, which is a central part of the criticism from health advocates and lawmakers. The regulatory landscape is shifting quickly, and more restrictions on retail sales are likely in the coming years.
Food-Grade vs. Medical-Grade Nitrous Oxide
Not all nitrous oxide is the same. Medical-grade N₂O, the kind used by dentists and in hospital settings, must meet strict purity standards of at least 99% with tight limits on contaminants. Food-grade nitrous oxide, like what’s found in Galaxy Gas, meets lower purity thresholds. Industrial-grade N₂O can be as low as 95% pure, with the remainder consisting of various impurities. When someone inhales a product designed for whipping cream, they’re breathing in a gas that was never tested or purified for safe human inhalation, with no monitoring of what else might be in the canister.
