FDA Exposed: Hundreds of Drugs Approved without Proof They Work
From the Brownstone Institute
The US Food and Drug Administration (FDA) has approved hundreds of drugs without proof that they work—and in some cases, despite evidence that they cause harm.
That’s the finding of a blistering two-year investigation by medical journalists Jeanne Lenzer and Shannon Brownlee, published by The Lever.
Reviewing more than 400 drug approvals between 2013 and 2022, the authors found the agency repeatedly ignored its own scientific standards.
One expert put it bluntly—the FDA’s threshold for evidence “can’t go any lower because it’s already in the dirt.”
A System Built on Weak Evidence
The findings were damning—73% of drugs approved by the FDA during the study period failed to meet all four basic criteria for demonstrating “substantial evidence” of effectiveness.
Those four criteria—presence of a control group, replication in two well-conducted trials, blinding of participants and investigators, and the use of clinical endpoints like symptom relief or extended survival—are supposed to be the bedrock of drug evaluation.
Yet only 28% of drugs met all four criteria—40 drugs met none.
These aren’t obscure technicalities—they are the most basic safeguards to protect patients from ineffective or dangerous treatments.
But under political and industry pressure, the FDA has increasingly abandoned them in favour of speed and so-called “regulatory flexibility.”
Since the early 1990s, the agency has relied heavily on expedited pathways that fast-track drugs to market.
In theory, this balances urgency with scientific rigour. In practice, it has flipped the process. Companies can now get drugs approved before proving that they work, with the promise of follow-up trials later.
But, as Lenzer and Brownlee revealed, “Nearly half of the required follow-up studies are never completed—and those that are often fail to show the drugs work, even while they remain on the market.”
“This represents a seismic shift in FDA regulation that has been quietly accomplished with virtually no awareness by doctors or the public,” they added.
More than half the approvals examined relied on preliminary data—not solid evidence that patients lived longer, felt better, or functioned more effectively.
And even when follow-up studies are conducted, many rely on the same flawed surrogate measures rather than hard clinical outcomes.
The result: a regulatory system where the FDA no longer acts as a gatekeeper—but as a passive observer.
Cancer Drugs: High Stakes, Low Standards
Nowhere is this failure more visible than in oncology.
Only 3 out of 123 cancer drugs approved between 2013 and 2022 met all four of the FDA’s basic scientific standards.
Most—81%—were approved based on surrogate endpoints like tumour shrinkage, without any evidence that they improved survival or quality of life.
Take Copiktra, for example—a drug approved in 2018 for blood cancers. The FDA gave it the green light based on improved “progression-free survival,” a measure of how long a tumour stays stable.
But a review of post-marketing data showed that patients taking Copiktra died 11 months earlier than those on a comparator drug.
It took six years after those studies showed the drug reduced patients’ survival for the FDA to warn the public that Copiktra should not be used as a first- or second-line treatment for certain types of leukaemia and lymphoma, citing “an increased risk of treatment-related mortality.”
Elmiron: Ineffective, Dangerous—And Still on the Market
Another striking case is Elmiron, approved in 1996 for interstitial cystitis—a painful bladder condition.
The FDA authorized it based on “close to zero data,” on the condition that the company conduct a follow-up study to determine whether it actually worked.
That study wasn’t completed for 18 years—and when it was, it showed Elmiron was no better than placebo.
In the meantime, hundreds of patients suffered vision loss or blindness. Others were hospitalized with colitis. Some died.
Yet Elmiron is still on the market today. Doctors continue to prescribe it.
“Hundreds of thousands of patients have been exposed to the drug, and the American Urological Association lists it as the only FDA-approved medication for interstitial cystitis,” Lenzer and Brownlee reported.
“Dangling Approvals” and Regulatory Paralysis
The FDA even has a term—”dangling approvals”—for drugs that remain on the market despite failed or missing follow-up trials.
One notorious case is Avastin, approved in 2008 for metastatic breast cancer.
It was fast-tracked, again, based on ‘progression-free survival.’ But after five clinical trials showed no improvement in overall survival—and raised serious safety concerns—the FDA moved to revoke its approval for metastatic breast cancer.
The backlash was intense.
Drug companies and patient advocacy groups launched a campaign to keep Avastin on the market. FDA staff received violent threats. Police were posted outside the agency’s building.
The fallout was so severe that for more than two decades afterwards, the FDA did not initiate another involuntary drug withdrawal in the face of industry opposition.
Billions Wasted, Thousands Harmed
Between 2018 and 2021, US taxpayers—through Medicare and Medicaid—paid $18 billion for drugs approved under the condition that follow-up studies would be conducted. Many never were.
The cost in lives is even higher.
A 2015 study found that 86% of cancer drugs approved between 2008 and 2012 based on surrogate outcomes showed no evidence that they helped patients live longer.
An estimated 128,000 Americans die each year from the effects of properly prescribed medications—excluding opioid overdoses. That’s more than all deaths from illegal drugs combined.
A 2024 analysis by Danish physician Peter Gøtzsche found that adverse effects from prescription medicines now rank among the top three causes of death globally.
Doctors Misled by the Drug Labels
Despite the scale of the problem, most patients—and most doctors—have no idea.
A 2016 survey published in JAMA asked practising physicians a simple question—what does FDA approval actually mean?
Only 6% got it right.
The rest assumed that it meant the drug had shown clear, clinically meaningful benefits—such as helping patients live longer or feel better—and that the data was statistically sound.
But the FDA requires none of that.
Drugs can be approved based on a single small study, a surrogate endpoint, or marginal statistical findings. Labels are often based on limited data, yet many doctors take them at face value.
Harvard researcher Aaron Kesselheim, who led the survey, said the results were “disappointing, but not entirely surprising,” noting that few doctors are taught about how the FDA’s regulatory process actually works.
Instead, physicians often rely on labels, marketing, or assumptions—believing that if the FDA has authorized a drug, it must be both safe and effective.
But as The Lever investigation shows, that is not a safe assumption.
And without that knowledge, even well-meaning physicians may prescribe drugs that do little good—and cause real harm.
Who Is the FDA Working for?
In interviews with more than 100 experts, patients, and former regulators, Lenzer and Brownlee found widespread concern that the FDA has lost its way.
Many pointed to the agency’s dependence on industry money. A BMJ investigation in 2022 found that user fees now fund two-thirds of the FDA’s drug review budget—raising serious questions about independence.
Yale physician and regulatory expert Reshma Ramachandran said the system is in urgent need of reform.
“We need an agency that’s independent from the industry it regulates and that uses high-quality science to assess the safety and efficacy of new drugs,” she told The Lever. “Without that, we might as well go back to the days of snake oil and patent medicines.”
For now, patients remain unwitting participants in a vast, unspoken experiment—taking drugs that may never have been properly tested, trusting a regulator that too often fails to protect them.
And as Lenzer and Brownlee conclude, that trust is increasingly misplaced.

A walk through a dozen convenience stores in Montgomery County, Pennsylvania, says a lot about how US nicotine policy actually works. Only about one in eight nicotine-pouch products for sale is legal. The rest are unauthorized—but they’re not all the same. Some are brightly branded, with uncertain ingredients, not approved by any Western regulator, and clearly aimed at impulse buyers. Others—like Sweden’s NOAT—are the opposite: muted, well-made, adult-oriented, and already approved for sale in Europe.
Yet in the United States, NOAT has been told to stop selling. In September 2025, the Food and Drug Administration (FDA) issued the company a warning letter for offering nicotine pouches without marketing authorization. That might make sense if the products were dangerous, but they appear to be among the safest on the market: mild flavors, low nicotine levels, and recyclable paper packaging. In Europe, regulators consider them acceptable. In America, they’re banned. The decision looks, at best, strange—and possibly arbitrary.
What the Market Shows
My October 2025 audit was straightforward. I visited twelve stores and recorded every distinct pouch product visible for sale at the counter. If the item matched one of the twenty ZYN products that the FDA authorized in January, it was counted as legal. Everything else was counted as illegal.
Two of the stores told me they had recently received FDA letters and had already removed most illegal stock. The other ten stores were still dominated by unauthorized products—more than 93 percent of what was on display. Across all twelve locations, about 12 percent of products were legal ZYN, and about 88 percent were not.
The illegal share wasn’t uniform. Many of the unauthorized products were clearly high-nicotine imports with flashy names like Loop, Velo, and Zimo. These products may be fine, but some are probably high in contaminants, and a few often with very high nicotine levels. Others were subdued, plainly meant for adult users. NOAT was a good example of that second group: simple packaging, oat-based filler, restrained flavoring, and branding that makes no effort to look “cool.” It’s the kind of product any regulator serious about harm reduction would welcome.
Enforcement Works
To the FDA’s credit, enforcement does make a difference. The two stores that received official letters quickly pulled their illegal stock. That mirrors the agency’s broader efforts this year: new import alerts to detain unauthorized tobacco products at the border (see also Import Alert 98-06), and hundreds of warning letters to retailers, importers, and distributors.
But effective enforcement can’t solve a supply problem. The list of legal nicotine-pouch products is still extremely short—only a narrow range of ZYN items. Adults who want more variety, or stores that want to meet that demand, inevitably turn to gray-market suppliers. The more limited the legal catalog, the more the illegal market thrives.
Why the NOAT Decision Appears Bizarre
The FDA’s own actions make the situation hard to explain. In January 2025, it authorized twenty ZYN products after finding that they contained far fewer harmful chemicals than cigarettes and could help adult smokers switch. That was progress. But nine months later, the FDA has approved nothing else—while sending a warning letter to NOAT, arguably the least youth-oriented pouch line in the world.
The outcome is bad for legal sellers and public health. ZYN is legal; a handful of clearly risky, high-nicotine imports continue to circulate; and a mild, adult-market brand that meets European safety and labeling rules is banned. Officially, NOAT’s problem is procedural—it lacks a marketing order. But in practical terms, the FDA is punishing the very design choices it claims to value: simplicity, low appeal to minors, and clean ingredients.
This approach also ignores the differences in actual risk. Studies consistently show that nicotine pouches have far fewer toxins than cigarettes and far less variability than many vapes. The biggest pouch concerns are uneven nicotine levels and occasional traces of tobacco-specific nitrosamines, depending on manufacturing quality. The serious contamination issues—heavy metals and inconsistent dosage—belong mostly to disposable vapes, particularly the flood of unregulated imports from China. Treating all “unauthorized” products as equally bad blurs those distinctions and undermines proportional enforcement.
A Better Balance: Enforce Upstream, Widen the Legal Path
My small Montgomery County survey suggests a simple formula for improvement.
First, keep enforcement targeted and focused on suppliers, not just clerks. Warning letters clearly change behavior at the store level, but the biggest impact will come from auditing distributors and importers, and stopping bad shipments before they reach retail shelves.
Second, make compliance easy. A single-page list of authorized nicotine-pouch products—currently the twenty approved ZYN items—should be posted in every store and attached to distributor invoices. Point-of-sale systems can block barcodes for anything not on the list, and retailers could affirm, once a year, that they stock only approved items.
Third, widen the legal lane. The FDA launched a pilot program in September 2025 to speed review of new pouch applications. That program should spell out exactly what evidence is needed—chemical data, toxicology, nicotine release rates, and behavioral studies—and make timely decisions. If products like NOAT meet those standards, they should be authorized quickly. Legal competition among adult-oriented brands will crowd out the sketchy imports far faster than enforcement alone.
The Bottom Line
Enforcement matters, and the data show it works—where it happens. But the legal market is too narrow to protect consumers or encourage innovation. The current regime leaves a few ZYN products as lonely legal islands in a sea of gray-market pouches that range from sensible to reckless.
The FDA’s treatment of NOAT stands out as a case study in inconsistency: a quiet, adult-focused brand approved in Europe yet effectively banned in the US, while flashier and riskier options continue to slip through. That’s not a public-health victory; it’s a missed opportunity.
If the goal is to help adult smokers move to lower-risk products while keeping youth use low, the path forward is clear: enforce smartly, make compliance easy, and give good products a fair shot. Right now, we’re doing the first part well—but failing at the second and third. It’s time to fix that.

Cigarettes kill nearly half a million Americans each year. Everyone knows it, including the Food and Drug Administration. Yet while the most lethal nicotine product remains on sale in every gas station, the FDA continues to block or delay far safer alternatives.
Nicotine pouches—small, smokeless packets tucked under the lip—deliver nicotine without burning tobacco. They eliminate the tar, carbon monoxide, and carcinogens that make cigarettes so deadly. The logic of harm reduction couldn’t be clearer: if smokers can get nicotine without smoke, millions of lives could be saved.
Sweden has already proven the point. Through widespread use of snus and nicotine pouches, the country has cut daily smoking to about 5 percent, the lowest rate in Europe. Lung-cancer deaths are less than half the continental average. This “Swedish Experience” shows that when adults are given safer options, they switch voluntarily—no prohibition required.
In the United States, however, the FDA’s tobacco division has turned this logic on its head. Since Congress gave it sweeping authority in 2009, the agency has demanded that every new product undergo a Premarket Tobacco Product Application, or PMTA, proving it is “appropriate for the protection of public health.” That sounds reasonable until you see how the process works.
Manufacturers must spend millions on speculative modeling about how their products might affect every segment of society—smokers, nonsmokers, youth, and future generations—before they can even reach the market. Unsurprisingly, almost all PMTAs have been denied or shelved. Reduced-risk products sit in limbo while Marlboros and Newports remain untouched.
Only this January did the agency relent slightly, authorizing 20 ZYN nicotine-pouch products made by Swedish Match, now owned by Philip Morris. The FDA admitted the obvious: “The data show that these specific products are appropriate for the protection of public health.” The toxic-chemical levels were far lower than in cigarettes, and adult smokers were more likely to switch than teens were to start.
The decision should have been a turning point. Instead, it exposed the double standard. Other pouch makers—especially smaller firms from Sweden and the US, such as NOAT—remain locked out of the legal market even when their products meet the same technical standards.
The FDA’s inaction has created a black market dominated by unregulated imports, many from China. According to my own research, roughly 85 percent of pouches now sold in convenience stores are technically illegal.
The agency claims that this heavy-handed approach protects kids. But youth pouch use in the US remains very low—about 1.5 percent of high-school students according to the latest National Youth Tobacco Survey—while nearly 30 million American adults still smoke. Denying safer products to millions of addicted adults because a tiny fraction of teens might experiment is the opposite of public-health logic.
There’s a better path. The FDA should base its decisions on science, not fear. If a product dramatically reduces exposure to harmful chemicals, meets strict packaging and marketing standards, and enforces Tobacco 21 age verification, it should be allowed on the market. Population-level effects can be monitored afterward through real-world data on switching and youth use. That’s how drug and vaccine regulation already works.
Sweden’s evidence shows the results of a pragmatic approach: a near-smoke-free society achieved through consumer choice, not coercion. The FDA’s own approval of ZYN proves that such products can meet its legal standard for protecting public health. The next step is consistency—apply the same rules to everyone.
Combustion, not nicotine, is the killer. Until the FDA acts on that simple truth, it will keep protecting the cigarette industry it was supposed to regulate.
