Nitrous oxide, commonly known as laughing gas, is increasingly being used recreationally, especially among young people, despite its potentially deadly effects. The gas is sold in cartridges, often under names like “Galaxy Gas” and “Miami Magic,” and is available in stores and online. Frequent use can cause severe health issues, such as cognitive impairment, memory loss, and irreversible brain damage. The number of deaths linked to nitrous oxide abuse has more than doubled in recent years. Despite its dangers, nitrous oxide remains unregulated in many areas, with some states enacting restrictions or bans on its recreational use. Research and prevention efforts are essential to curbing the rise in misuse.
The U.S. Food and Drug Administration is warning Americans about the ever-increasing and potentially deadly recreational use of nitrous oxide products, particularly among young people.
Marketed with names like “Galaxy Gas” and “Miami Magic,” and often sold in steel cartridges known as “whippets,” these products are cheap and readily available at gas stations, convenience stores, smoke shops and major retail outlets, including Walmart. They’re also sold online.
Recreational and continued use of nitrous oxide can cause a wide range of serious health problems, and in some cases, death.
A long list of potential harms
The list of serious side effects from frequent use is long. It includes: cognitive impairment, memory problems, hallucinations, headaches, lightheadedness, mood disturbances, blood clots, limb weakness, trouble walking, peripheral neuropathy, impaired bowel or bladder function, spinal cord degeneration and irreversible brain damage. Vitamin B-12 deficiency is common and can lead to nerve and brain damage.
Deaths in the U.S. attributed to abuse of nitrous oxide jumped more than 100% between 2019 and 2023; over a five-year period, emergency department visits rose 32%.
All told, more than 13 million Americans have misused nitrous oxide at least once during their lifetimes. This includes children: In 2024, just over 4% of eighth graders and about 2% of 12th graders said they’ve tried inhalants. Nitrous oxide is among the most abused of these inhalants due to its low cost, easy availability and commercial appeal – one flavor of the gas is named “pink bubble gum.”
Pure nitrous, inhaled for a quick high, can be lethal.
The few studies on the use of nitrous oxide are limited mainly to case reports – that is, a report on a single patient. Although limited in scope, they’re alarming.
Physicians began using it in the U.S. around the mid-19th century after Horace Wells, a dentist, attended a stage show – called “Laughing Gas Entertainment” – and saw the numbing effect that nitrous oxide had on audience volunteers. By coincidence, Wells was having a wisdom tooth removed the next day, so he tried the gas during his procedure. The nitrous oxide worked; Wells said he felt no pain. Thereafter, medicinal use of the gas was gradually accepted.
As of May 2025, four U.S. states – Louisiana, Michigan, Alabama and California – have banned the recreational use of nitrous oxide, and more than 30 states are working on legislation to ban or at least restrict sale of the products. In addition, numerous lawsuits filed against the manufacturers are in court.
Through appropriate legislation, regulation, education and intervention, nitrous oxide abuse can be slowed or stopped. Otherwise, these products – with their sleek packaging and attractive social media campaigns that obscure their dangers – remain a growing threat to our children.

Federal cuts to research funding under the Trump administration threaten both scientific progress and ethical oversight in biomedical research. The National Institutes of Health (NIH) has been pivotal in supporting innovations such as cancer treatments, but cuts and hiring freezes have led to suspended clinical trials and delayed studies. Ethical concerns surrounding emerging biotechnologies like brain organoids underscore the importance of federal research infrastructure in safeguarding scientific integrity. This oversight is vital to prevent exploitation, ensure voluntary consent, and protect participants from harm, maintaining global leadership in biomedical research. The article calls for continued support to sustain medical advancements and safeguard public health.

As the Trump administration continues to make significant cutsto NIH budgetsand personnel and to freeze billions of dollars of funding to major research universities – citing ideological concerns – there’s more being threatened than just progress in science and medicine. Something valuable but often overlooked is also being hit hard: preventing research abuse.
The Trump administration has deeply culled U.S. science across agencies and institutions.
It is clear to us, as legal andbioethics scholars whose research often focuses on the ethical, legal and social implications of emerging biotechnologies, that these directives will have profoundly negative consequences for medical research and human health, with ripple effects that will last decades. Our scholarship demonstrates that in order to contribute to knowledge and, ultimately, to biomedical treatments, medical research at every stage depends on significant infrastructure support and ethical oversight.
Our recent focus on brain organoid research – 3D lab models grown from human stem cells that simulate brain structure and function – shows how federal support for research is key to not only promote innovation, but to protect participants and future patients.
History of NIH and research ethics
The National Institutes of Health began as a one-room laboratory within the Marine Hospital Service in 1887. After World War I, chemists involved in the war effort sought to apply their knowledge to medicine. They partnered with Louisiana Sen. Joseph E. Ransdell who, motivated by the devastation of malaria, yellow fever and the 1928 influenza pandemic, introduced federal legislation to support basic research and fund fellowships focusing on solving medical problems.
As science advanced, so did the need for guardrails. After World War II, among the top Nazi leaders prosecuted for war crimes were physicians who conducted experiments on people without consent, such as exposure to hypothermia and infectious disease. The verdicts of these Doctors’ Trials included 10 points about ethical human research that became the Nuremberg Code, emphasizing voluntary consent to participation, societal benefit as the goal of human research, and significant limitations on permissible risks of harm. The World Medical Association established complementary international guidelines for physician-researchers in the 1964 Declaration of Helsinki.

In the 1970s, information about the Tuskegee study – a deceptive and unethical 40-year study of untreated syphilis in Black men – came to light. The researchers told study participants they would be given treatment but did not give them medication. They also prevented participants from accessing a cure when it became available in order to study the disease as it progressed. The men enrolled in the study experienced significant health problems, including blindness, mental impairment and death.
The public outrage that followed starkly demonstrated that the U.S. couldn’t simply rely on international guidelines but needed federal standards on research ethics. As a result, the National Research Act of 1974 led to the Belmont Report, which identified ethical principles essential to human research: respect for persons, beneficence and justice.
Federal regulations reinforced these principles by requiring all federally funded research to comply with rigorous ethical standards for human research. By prohibiting financial conflicts of interest and by implementing an independent ethics review process, new policies helped ensure that federally supported research has scientific and social value, is scientifically valid, fairly selects and adequately protects participants.
These standards and recommendations guide both federally and nonfederally funded research today. The breadth of NIH’s mandate and budget has provided not only the essential structure for research oversight, but also key resources for ethics consultation and advice.
Brain organoids and the need for ethical inquiry
Biomedical research on cell andanimal models requires extensive ethics oversight systems that complement those for human research. Our research on the ethical and policy issues of human brain organoid research provides a good example of the complexities of biomedical research and the infrastructure and oversight mechanisms necessary to support it.
Brain organoids are built on knowledge about the fundamentals of biology that was developed primarily in universities receiving federal funding. Organoid technology began in 1907 with research on sponge cells, and continued in the 1980s with advances instem cell research. Since researchers generated the first human organoid in 2009, the field has rapidly expanded.

These advances were only possible through federally supported research infrastructure, which helps ensure the quality of all biomedical research. Indirect costs cover operational expenses necessary to maintain research safety and ethics, including utilities, administrative support, biohazard handling and regulatory compliance. In these ways, federally supported research infrastructure protects and promotes the scientific and ethical value of biotechnologies like brain organoids.
Brain organoid research requires significant scientific and ethical inquiry to safely reach its future potential. It raises potential moral and legal questions about donor consent, the extent to which organoids should be grown and how they should be disposed, and consciousness and personhood. As science progresses, infrastructure for oversight can help ensure these ethical and societal issues are addressed.
New frontiers in scientific research
Since World War II, there has been bipartisan support for scientific innovation, in part because it is an economic and national security imperative. As Harvard University President Alan Garber recently wrote, “[n]ew frontiers beckon us with the prospect of life-changing advances. … For the government to retreat from these partnerships now risks not only the health and well-being of millions of individuals but also the economic security and vitality of our nation.”
Cuts to research overhead may seem like easy savings, but it fails to account for the infrastructure that provides essential support for scientific innovation. The investment the NIH has put into academic research is significantly paid forward, adding nearly US$95 billion to local economies in fiscal year 2024, or $2.46 for every $1 of grant funding. NIH funding had also supported over 407,700 jobs that year.
Organoid research is just one of the essential components in the process of learning about the brain and using that knowledge to find better treatment for diseases affecting the brain.
Science benefits society only if it is rigorous, ethically conducted and fairly funded. Current NIH policy directives and steep cuts to the agency’s size and budget, along with attacks on universities, undermine globally shared goals of increasing understanding and improving human health.
The federal system of overseeing and funding biomedical science may need a scalpel, but to defund efforts based on “efficiency” is to wield a chainsaw.

Women with chronic gynecological pain, such as endometriosis and vulvodynia, often face skepticism and dismissal from healthcare providers, a phenomenon known as medical gaslighting. Many are told their pain is psychological, leading to years of misdiagnosis and mistreatment. Historical gender bias, lack of medical research, and societal stigma contribute to this issue. Studies show that women’s pain is frequently undervalued, and they are often offered psychological care instead of effective treatment. The underfunding of women’s health research exacerbates this problem, with some patients turning to social media for support. Addressing medical gaslighting requires systemic change, including better clinical training and increased research funding.
For people with chronic gynecological pain conditions, pain can be constant, making everyday activities like sitting, riding a bicycle and even wearing underwear extremely uncomfortable. For many of these people – most of whom identify as women – sexual intercourse and routine pelvic exams are unbearable.
Endometriosis and vulvodynia, or chronic genital pain, are common gynecological conditions that can cause severe pain. They each affect about 1 in 10 American women.
Yet many women face skepticism and gaslighting in health care settings when they seek care for this type of pain.
We know this well through our research on social cognition and on how people with misunderstood health conditions manage difficult conversations with their doctors and family, as well as through volunteer work alongside people living with these conditions.
We’ve consistently found that medical gaslighting around chronic gynecological pain is a complex societal problem, fueled by holes in medical research and training.
‘It’s all in your head’
A 2024 study of patients who went to a clinic for vulvovaginal pain – pain experienced in the external female genitals and vagina – found that 45% of these patients had been told that they “just needed to relax more” and 39% were made to feel that they were “crazy”. A staggering 55% had considered giving up on seeking care.
These results echo what one of us – Elizabeth Hintz – found in her 2023 meta-synthesis: Female patients with chronic pain conditions frequently hear this “It’s all in your head” response from doctors.
Another study followed patients in two different major U.S. cities who were seeking care for vulvovaginal pain. The researchers found that most patients saw multiple clinicians but never received a diagnosis. Given the challenges of seeking medical care, many patients turn to social media sources like Reddit for support and information.
These studies, among others, illustrate how people with these conditions often spend years going to clinician after clinician seeking care and being told their pain is psychological or perhaps not even real. Given these experiences, why do patients keep seeking care?
“Let me describe the pain that would drive me to try so many different doctors, tests and treatments,” a patient with vulvovaginal pain said to her doctor. For her, sex “is like taking your most sensitive area and trying to rip it apart.”
“I can now wear any pants or underwear that I want with no pain,” said another patient after successful treatment. “I never realized how much of a toll the pain took on my body every day until it was gone.”
The World Health Organization estimates that at least 1 in 10 women suffers from endometriosis, yet many doctors miss it or dismiss it.
This cycle of gaslighting compounds the burden of the pain and might lead to long-term psychological effects like anxiety, depression and post-traumatic stress symptoms. For some, the repeated experience of being dismissed by clinicians erodes their sense of trust in the health care system. They might hesitate to seek medical attention in the future, fearing they will once again be dismissed.
Although some chronic gynecological pain conditions like endometriosis are gaining public attention and becoming better understood, these dynamics persist.
A funding crisis
Part of the reason for the misunderstanding surrounding chronic gynecological pain conditions is the lack of research on them. A January 2025 report from the National Academies found that research on diseases disproportionately affecting women were underfunded compared with diseases disproportionately affecting men.
This problem has gotten worse over time. The proportion of funding from the National Institutes of Health spent on women’s health has actually declined over the past decade. Despite these known disparities, in April 2025 the Trump administration threatened to end funding for the Women’s Health Initiative, a long-running women’s health research program, further worsening the problem.
Without sustained federal funding for women’s health research, conditions like endometriosis and vulvodynia will remain poorly understood, leaving clinicians in the dark and patients stranded.
Disparities in care
As hard as it is for any female patient to have their pain believed and treated, gaining recognition for chronic pain is even harder for those who face discrimination based on class or race.
One 2016 study found that half of the white medical students surveyed endorsed at least one false belief about biological differences between Black and white patients, such as that Black people have physically thicker skin or less sensitive nerve endings than white people. The medical students and residents who endorsed these false beliefs also underestimated Black patients’ pain and offered them less accurate treatment recommendations.

These lingering erroneous beliefs about gender and race are key reasons patients’ pain is dismissed, misunderstood and ignored. The very real-life consequences for patients include delayed diagnosis, treatment and even death.
Practical steps to disrupt medical gaslighting
Correcting these problems will require a shift in clinical training, so as to challenge biased views about pain in women and racial minorities and to educate clinicians about common pain conditions like vulvodynia. Research suggests that medical training needs to teach students to better listen to patients’ lived experiences and admit when an answer isn’t known.
In the meantime, people navigating the health care system can take practical steps when encountering dismissive care.
Although these steps do not address the roots of medical gaslighting, they can empower patients to better understand the medical conditions that could cause their symptoms, helping to counteract the effects of gaslighting.
If someone you know has experienced medical gaslighting and would like support, there are resources available.

Contaminated milk from one plant in Illinois sickened thousands with Salmonella in 1985 − as outbreaks rise in the US, lessons from this one remain true

In 1985, contaminated milk in Illinois led to a Salmonella outbreak that infected hundreds of thousands of people across the United States and caused at least 12 deaths. At the time, it was the largest single outbreak of foodborne illness in the U.S. and remains the worst outbreak of Salmonella food poisoning in American history.
Many questions circulated during the outbreak. How could this contamination occur in a modern dairy farm? Was it caused by a flaw in engineering or processing, or was this the result of deliberate sabotage? What roles, if any, did politics and failed leadership play?
From my 50 years of working in public health, I’ve found that reflecting on the past can help researchers and officials prepare for future challenges. Revisiting this investigation and its outcome provides lessons on how food safety inspections go hand in hand with consumer protection and public health, especially as hospitalizations and deaths from foodborne illnesses rise.
Contamination, investigation and intrigue
The Illinois Department of Public Health and the U.S. Centers for Disease Control and Prevention led the investigation into the outbreak. The public health laboratories of the city of Chicago and state of Illinois were also closely involved in testing milk samples.
Investigators and epidemiologists from local, state and federal public health agencies found that specific lots of milk with expiration dates up to April 17, 1985, were contaminated with Salmonella. The outbreak may have been caused by a valve at a processing plant that allowed pasteurized milk to mix with raw milk, which can carry several harmful microorganisms, including Salmonella.
Overall, labs and hospitals in Illinois and five other Midwest states – Indiana, Iowa, Michigan, Minnesota and Wisconsin – reported over 16,100 cases of suspected Salmonella poisoning to health officials.
To make dairy products, skimmed milk is usually separated from cream, then blended back together in different levels to achieve the desired fat content. While most dairies pasteurize their products after blending, Hillfarm Dairy in Melrose Park, Illinois, pasteurized the milk first before blending it into various products such as skim milk and 2% milk.
Subsequent examination of the production process suggested that Salmonella may have grown in the threads of a screw-on cap used to seal an end of a mixing pipe. Investigators also found this strain of Salmonella 10 months earlier in a much smaller outbreak in the Chicago area.
The contaminated milk was produced at Hillfarm Dairy in Melrose Park, which was operated at the time by Jewel Companies Inc. During an April 3 inspection of the company’s plant, the Food and Drug Administration found 13 health and safety violations.
The legal fallout of the outbreak expanded when the Illinois attorney general filed suit against Jewel Companies Inc., alleging that employees at as many as 18 stores in the grocery chain violated water pollution laws when they dumped potentially contaminated milk into storm sewers. Later, a Cook County judge found Jewel Companies Inc. in violation of the court order to preserve milk products suspected of contamination and maintain a record of what happened to milk returned to the Hillfarm Dairy.
Political fallout also ensued. The Illinois governor at the time, James Thompson, fired the director of the Illinois Public Health Department when it was discovered that he was vacationing in Mexico at the onset of the outbreak and failed to return to Illinois. Notably, the health director at the time of the outbreak was not a health professional. Following this episode, the governor appointed public health professional and medical doctor Bernard Turnock as director of the Illinois Department of Public Health.
In 1987, after a nine-month trial, a jury determined that Jewel officials did not act recklessly when Salmonella-tainted milk caused one of the largest food poisoning outbreaks in U.S. history. No punitive damages were awarded to victims, and the Illinois Appellate Court later upheld the jury’s decision.
Raw milk is linked to many foodborne illnesses.
Lessons learned
History teaches more than facts, figures and incidents. It provides an opportunity to reflect on how to learn from past mistakes in order to adapt to future challenges. The largest Salmonella outbreak in the U.S. to date provides several lessons.
For one, disease surveillance is indispensable to preventing outbreaks, both then and now. People remain vulnerable to ubiquitous microorganisms such as Salmonella and E. coli, and early detection of an outbreak could stop it from spreading and getting worse.
Additionally, food production facilities can maintain a safe food supply with careful design and monitoring. Revisiting consumer protections can help regulators keep pace with new threats from new or unfamiliar pathogens.
