On the presidential campaign trail, former President Donald Trump is, once again, promising to repeal and replace the Affordable Care Act — a nebulous goal that became one of his administration’s splashiest policy failures.

“We’re going to fight for much better health care than Obamacare. Obamacare is a catastrophe,” Trump said at a campaign stop in Iowa on Jan. 6.

The perplexing revival of one of Trump’s most politically damaging crusades comes at a time when the Obama-era health law is even more popular and widely used than it was in 2017, when Trump and congressional Republicans proved unable to pass their own plan to replace it. That failed effort was a big part of why Republicans lost control of the House of Representatives in the 2018 midterms.

Despite repeated promises, Trump never presented his own Obamacare replacement. And much of what Trump’s administration actually accomplished in health care has been reversed by the Biden administration.

Still, Trump secured some significant policy changes that remain in place today, including efforts to bring more transparency to prices charged by hospitals and paid by health insurers.

Trying to predict Trump’s priorities in a second term is even more difficult given that he frequently changes his positions on issues, sometimes multiple times.

The Trump campaign did not respond to a request for comment.

Perhaps Trump’s biggest achievement is something he rarely talks about on the campaign trail. His administration’s “Operation Warp Speed” managed to create, test, and bring to market a covid-19 vaccine in less than a year, far faster than even the most optimistic predictions.

Many of Trump’s supporters, though, don’t support — and some even vehemently oppose — covid vaccines.

Here is a recap of Trump’s health care record:

Public Health

Trump’s pandemic response dominates his overall record on health care.

More than 400,000 Americans died from covid over Trump’s last year in office. His travel bans and other efforts to prevent the global spread of the virus were ineffective, his administration was slower than other countries’ governments to develop a diagnostic test, and he publicly clashed with his own government’s health officials over the response.

Ahead of the 2020 election, Trump resumed large rallies and other public campaign events that many public health experts regarded as reckless in the face of a highly contagious, deadly virus. He personally flouted public health guidance after contracting covid himself and ending up hospitalized.

At the same time, despite what many saw as a politicization of public health by the White House, Trump signed a massive covid relief bill (after first threatening to veto it). He also presided over some of the largest boosts for the National Institutes of Health’s budget since the turn of the century. And the mRNA-based vaccines Operation Warp Speed helped develop were an astounding scientific breakthrough credited with helping save millions of lives while laying the groundwork for future shots to fight other diseases including cancer.

Abortion

Trump’s biggest contribution to abortion policy was indirect: He appointed three Supreme Court justices, who were instrumental in overturning the constitutional right to an abortion.

During his 2024 campaign, Trump has been all over the place on the red-hot issue. Since the Supreme Court overturned Roe v. Wade in 2022, Trump has bemoaned the issue as politically bad for Republicans; criticized one of his rivals, Florida Gov. Ron DeSantis, for signing a six-week abortion ban; and vowed to broker a compromise with “both sides” on abortion, promising that “for the first time in 52 years, you’ll have an issue that we can put behind us.”

He has so far avoided spelling out how he’d do that, or whether he’d support a national abortion ban after any number of weeks.

More recently, however, Trump appears to have mended fences over his criticism of Florida’s six-week ban and more with key abortion opponents, whose support helped him get elected in 2016 — and whom he repaid with a long list of policy changes during his presidency.

Among the anti-abortion actions taken by the Trump administration were a reinstatement of the “Mexico City Policy” that bars giving federal funds to international organizations that support abortion rights; a regulation to bar Planned Parenthood and other organizations that provide abortions from the federal family planning program, Title X; regulatory changes designed to make it easier for health care providers and employers to decline to participate in activities that violate their religious and moral beliefs; and other changes that made it harder for NIH scientists to conduct research using fetal tissue from elective abortions.

All of those policies have since been overturned by the Biden administration.

Health Insurance

Unlike Trump’s policies on reproductive health, many of his administration’s moves related to health insurance still stand.

For example, in 2020, Trump signed into law the No Surprises Act, a bipartisan measure aimed at protecting patients from unexpected medical bills stemming from payment disputes between health care providers and insurers. The bill was included in the $900 billion covid relief package he opposed before signing, though Trump had expressed support for ending surprise medical bills.

His administration also pushed — over the vehement objections of health industry officials — price transparency regulations that require hospitals to post prices and insurers to provide estimated costs for procedures. Those requirements also remain in place, although hospitals in particular have been slow to comply.

Medicaid

While first-time candidate Trump vowed not to cut popular entitlement programs like Medicare, Medicaid, and Social Security, his administration did not stick to that promise. The Affordable Care Act repeal legislation Trump supported in 2017 would have imposed major cuts to Medicaid, and his Department of Health and Human Services later encouraged states to require Medicaid recipients to prove they work in order to receive health insurance.

Drug Prices

One of the issues the Trump administration was most active on was reducing the price of prescription drugs for consumers — a top priority for both Democratic and Republican voters. But many of those proposals were blocked by the courts.

One Trump-era plan that never took effect would have pegged the price of some expensive drugs covered by Medicare to prices in other countries. Another would have required drug companies to include prices in their television advertisements.

A regulation allowing states to import cheaper drugs from Canada did take effect, in November 2020. However, it took until January 2024 for the FDA, under Trump’s successor, to approve the first importation plan, from Florida. Canada has said it won’t allow exports that risk causing drug shortages in that country, leaving unclear whether the policy is workable.

Trump also signed into law measures allowing pharmacists to disclose to patients when the cash price of a drug is lower than the cost using their insurance. Previously pharmacists could be barred from doing so under their contracts with insurers and pharmacy benefit managers.

Veterans’ Health

Trump is credited by some advocates for overhauling Department of Veterans Affairs health care. However, while he did sign a major bill allowing veterans to obtain care outside VA facilities, White House officials also tried to scuttle passage of the spending needed to pay for the initiative.

Medical Freedom

Trump scored a big win for the libertarian wing of the Republican Party when he signed into law the “Right to Try Act,” intended to make it easier for patients with terminal diseases to access drugs or treatments not yet approved by the FDA.

But it is not clear how many patients have managed to obtain treatment using the law because it is aimed at the FDA, which has traditionally granted requests for “compassionate use” of not-yet-approved drugs anyway. The stumbling block, which the law does not address, is getting drug companies to release doses of medicines that are still being tested and may be in short supply.

Trump said in a Jan. 10 Fox News town hall that the law had “saved thousands and thousands” of lives. There’s no evidence for the claim.

Lori Tipton is among the growing number of people who say that MDMA, also known as ecstasy, saved their lives.

Raised in New Orleans by a mother with untreated bipolar disorder who later killed herself and two others, Tipton said she endured layers of trauma that eventually forced her to seek treatment for crippling anxiety and hypervigilance. For 10 years nothing helped, and she began to wonder if she was “unfixable.”

Then she answered an ad for a clinical trial for MDMA-assisted therapy to treat post-traumatic stress disorder. Tipton said the results were immediate, and she is convinced the drug could help a lot of people. But even as regulators weigh approval of the first MDMA-based treatment, she’s worried that it won’t reach those who need it most.

“The main thing that I’m always concerned about is just accessibility,” the 43-year-old nonprofit project manager said. “I don’t want to see this become just another expensive add-on therapy for people who can afford it when people are dying every day by their own hand because of PTSD.”

MDMA is part of a new wave of psychoactive drugs that show great potential for treating conditions such as severe depression and PTSD. Investors are piling into the nascent field, and a host of medications based on MDMA, LSD, psychedelic mushrooms, ketamine, the South American plant mixture ayahuasca, and the African plant ibogaine are now under development, and in some cases vying for approval by the Food and Drug Administration.

Proponents hope the efforts could yield the first major new therapies for mental illness since the introduction of modern antidepressants in the 1980s. But not all researchers are convinced that their benefits have been validated, or properly weighed against the risks. And they can be difficult to assess using traditional clinical trials.

The first MDMA-assisted assisted therapy appeared to be on track for FDA approval this August, but a recent report from an independent review committee challenged the integrity of the trial data from the drug’s maker, Lykos Therapeutics, a startup founded by a psychedelic research and advocacy group. The FDA will convene a panel of independent investigators on June 4 to determine whether to recommend the drug’s approval.

Proponents of the new therapies also worry that the FDA will impose treatment protocols, such as requiring multiple trained clinicians to monitor a patient for extended periods, that will render them far too expensive for most people.

Tipton’s MDMA-assisted therapy included three eight-hour medication sessions overseen by two therapists, each followed by an overnight stay at the facility and an integration session the following day.

“It does seem that some of these molecules can be administered safely,” said David Olson, director of the University of California-Davis Institute for Psychedelics and Neurotherapeutics. “I think the question is can they be administered safely at the scale needed to really make major improvements in mental health care.”

Breakthrough Therapies?

Psychedelics and other psychoactive substances, among the medicines with the oldest recorded use, have long been recognized for their potential therapeutic benefits. Modern research on them started in the mid-20th century, but clinical trial results didn’t live up to the claims of advocates, and they eventually got a bad name both from their use as party drugs and from rogue CIA experiments that involved dosing unsuspecting individuals.

The 1970 Controlled Substances Act made most psychoactive drugs illegal before any treatments were brought to market, and MDMA was classified as a Schedule 1 substance in 1985, which effectively ended any research. It wasn’t until 2000 that scientists at Johns Hopkins University were granted regulatory approval to study psilocybin anew.

Ketamine was in a different category, having been approved as an anesthetic in 1970. In the early 2000s, researchers discovered its antidepressant effects, and a ketamine-based therapy, Spravato, received FDA approval in 2019. Doctors can also prescribe generic ketamine off-label, and hundreds of clinics have sprung up across the nation. A clinical trial is underway to evaluate ketamine’s effectiveness in treating suicidal depression when used with other psychiatric medications.

Ketamine’s apparent effectiveness sparked renewed interest in the therapeutic potential of other psychoactive substances.

They fall into distinct categories: MDMA is an entactogen, also known as an empathogen, which induces a sense of connectedness and emotional communion, while LSD, psylocibin, and ibogaine are psychedelics, which create altered perceptual states. Ketamine is a dissociative anesthetic, though it can produce hallucinations at the right dose.

Despite the drugs’ differences, Olson said they all create neuroplasticity and allow the brain to heal damaged neural circuits, which imaging shows can be shriveled up in patients with addiction, depression, and PTSD.

“All of these brain conditions are really disorders of neural circuits,” Olson said. “We’re basically looking for medicines that can regrow these neurons.”

Psychedelics are particularly good at doing this, he said, and hold promise for treating diseases including Alzheimer’s.

A number of psychoactive drugs have now received the FDA’s “breakthrough therapy” designation, which expedites development and review of drugs with the potential to treat serious conditions.

But standard clinical trials, in which one group of patients is given the drug and a control group is given a placebo, have proven problematic, for the simple reason that people have no trouble determining whether they’ve gotten the real thing.

The final clinical trial for Lykos’ MDMA treatment showed that 71% of participants no longer met the criteria for PTSD after 18 weeks of taking the drug versus 48% in the control group.

A March report by the Institute for Clinical and Economic Review, an independent research group, questioned the company’s clinical trial results and challenged the objectivity of MDMA advocates who participated in the study as both patients and therapists. The institute also questioned the drug’s cost-effectiveness, which insurers factor into coverage decisions.

Lykos, a public benefit company, was formed in 2014 as an offshoot of the Multidisciplinary Association for Psychedelic Studies, a nonprofit that has invested more than $150 million into psychedelic research and advocacy.

The company said its researchers developed their studies in partnership with the FDA and used independent raters to ensure the reliability and validity of the results.

“We stand behind the design and results of our clinical trials,” a Lykos spokesperson said in an email.

There are other hazards too. Psychoactive substances can put patients in vulnerable states, making them potential victims for financial exploitation or other types of abuse. In Lykos’ second clinical trial, two therapists were found to have spooned, cuddled, blindfolded, and pinned down a female patient who was in distress.

The substances can also cause shallow breathing, heart issues, and hyperthermia.

To mitigate risks, the FDA can put restrictions on how drugs are administered.

“These are incredibly potent molecules and having them available in vending machines is probably a bad idea,” said Hayim Raclaw of Negev Capital, a venture capital fund focused on psychedelic drug development.

But if the protocols are too stringent, access is likely to be limited.

Rachel del Dosso, a trauma therapist in the greater Los Angeles area who offers ketamine-assisted therapy, said she’s been following the research on drugs like MDMA and psilocybin and is excited for their therapeutic potential but has reservations about the practicalities of treatment.

“As a therapist in clinical practice, I’ve been thinking through how could I make that accessible,” she said. “Because it would cost a lot for [patients] to have me with them for the whole thing.”

Del Dosso said a group therapy model, which is sometimes used in ketamine therapy, could help scale the adoption of other psychoactive treatments, too.

Artificial Intelligence and Analogs

Researchers expect plenty of new discoveries in the field. One of the companies Negev has invested in, Mindstate Design Labs, uses artificial intelligence to analyze “trip reports,” or self-reported drug experiences, to identify potentially therapeutic molecules. Mindstate has asked the FDA to green-light a clinical trial of the first molecule identified through this method, 5-MeO-MiPT, also known as moxy.

AlphaFold, an AI program developed by Google’s DeepMind, has identified thousands of potential psychedelic molecules.

There’s also a lot of work going into so-called analog compounds, which have the therapeutic effects of hallucinogens but without the hallucinations. The maker of a psilocybin analog announced in March that the FDA had granted it breakthrough therapy status.

“If you can harness the neuroplasticity-promoting properties of LSD while also creating an antipsychotic version of it, then that can be pretty powerful,” Olson said.
