Benjamin Han, a geriatrician and addiction medicine specialist at the University of California-San Diego, tells his students a cautionary tale about a 76-year-old patient who, like many older people, struggled with insomnia.

“She had problems falling asleep, and she’d wake up in the middle of the night,” he said. “So her daughter brought her some sleep gummies” — edible cannabis candies.

“She tried a gummy after dinner and waited half an hour,” Han said.

Feeling no effects, she took another gummy, then one more — a total of four over several hours.

Han advises patients who are trying cannabis to “start low; go slow,” beginning with products that contain just 1 or 2.5 milligrams of tetrahydrocannabinol, or THC, the psychoactive ingredient that many cannabis products contain. Each of the four gummies this patient took, however, contained 10 milligrams.

The woman started experiencing intense anxiety and heart palpitations. A young person might have shrugged off such symptoms, but this patient had high blood pressure and atrial fibrillation, a heart arrhythmia. Frightened, she went to an emergency room.

Lab tests and a cardiac work-up determined the woman wasn’t having a heart attack, and the staff sent her home. Her only lingering symptom was embarrassment, Han said. But what if she’d grown dizzy or lightheaded and was hurt in a fall? He said he has had patients injured in falls or while driving after using cannabis. What if the cannabis had interacted with the prescription drugs she took?

“As a geriatrician, it gives me pause,” Han said. “Our brains are more sensitive to psychoactive substances as we age.”

Thirty-nine states and the District of Columbia now allow cannabis use for medical reasons, and in 24 of those states, as well as the district, recreational use is also legal. As older adults’ use climbs, “the benefits are still unclear,” Han said. “But we’re seeing more evidence of potential harms.”

A wave of recent research points to reasons for concern for older users, with cannabis-related emergency room visits and hospitalizations rising, and a Canadian study finding an association between such acute care and subsequent dementia. Older people are more apt than younger ones to try cannabis for therapeutic reasons: to relieve chronic pain, insomnia, or mental health issues, though evidence of its effectiveness in addressing those conditions remains thin, experts said.

In an analysis of national survey data published June 2 in the medical journal JAMA, Han and his colleagues reported that “current” cannabis use (defined as use within the previous month) had jumped among adults age 65 or older to 7% of respondents in 2023, from 4.8% in 2021. In 2005, he pointed out, fewer than 1% of older adults reported using cannabis in the previous year.

What’s driving the increase? Experts cite the steady march of state legalization — use by older people is highest in those states — while surveys show that the perceived risk of cannabis use has declined. One national survey found that a growing proportion of American adults — 44% in 2021 — erroneously thought it safer to smoke cannabis daily than cigarettes. The authors of the study, in JAMA Network Open, noted that “these views do not reflect the existing science on cannabis and tobacco smoke.”

The cannabis industry also markets its products to older adults. The Trulieve chain gives a 10% discount, both in stores and online, to those it calls “wisdom” customers, 55 or older. Rise Dispensaries ran a yearlong cannabis education and empowerment program for two senior centers in Paterson, New Jersey, including field trips to its dispensary.

The industry has many satisfied older customers. Liz Logan, 67, a freelance writer in Bronxville, New York, had grappled with sleep problems and anxiety for years, but the conditions grew particularly debilitating two years ago, as her husband was dying of Parkinson’s disease. “I’d frequently be awake until 5 or 6 in the morning,” she said. “It makes you crazy.”

Looking online for edible cannabis products, Logan found that gummies containing cannabidiol, known as CBD, alone didn’t help, but those with 10 milligrams of THC did the trick without noticeable side effects. “I don’t worry about sleep anymore,” she said. “I’ve solved a lifelong problem.”

But studies in the United States and Canada, which legalized nonmedical cannabis use for adults nationally in 2018, show climbing rates of cannabis-related health care use among older people, both in outpatient settings and in hospitals.

In California, for instance, cannabis-related emergency room visits by those 65 or older rose, to 395 per 100,000 visits in 2019 from about 21 in 2005. In Ontario, acute care (meaning emergency visits or hospital admissions) resulting from cannabis use increased fivefold in middle-aged adults from 2008 to 2021, and more than 26 times among those 65 and up.

“It’s not reflective of everyone who’s using cannabis,” cautioned Daniel Myran, an investigator at the Bruyère Health Research Institute in Ottawa and lead author of the Ontario study. “It’s capturing people with more severe patterns.”

But since other studies have shown increased cardiac risk among some cannabis users with heart disease or diabetes, “there’s a number of warning signals,” he said.

For example, a disturbing proportion of older veterans who currently use cannabis screen positive for cannabis use disorder, a recent JAMA Network Open study found.

As with other substance use disorders, such patients “can tolerate high amounts,” said the lead author, Vira Pravosud, a cannabis researcher at the Northern California Institute for Research and Education. “They continue using even if it interferes with their social or work or family obligations” and may experience withdrawal if they stop.

Among 4,500 older veterans (with an average age of 73) seeking care at Department of Veterans Affairs health facilities, researchers found that more than 10% had reported cannabis use within the previous 30 days. Of those, 36% fit the criteria for mild, moderate, or severe cannabis use disorder, as established in the Diagnostic and Statistical Manual of Mental Disorders.

VA patients differ from the general population, Pravosud noted. They are much more likely to report substance misuse and have “higher rates of chronic diseases and disabilities, and mental health conditions like PTSD” that could lead to self-medication, she said.

Current VA policies don’t require clinicians to ask patients about cannabis use. Pravosud thinks that they should.

Moreover, “there’s increasing evidence of a potential effect on memory and cognition,” said Myran, citing his team’s study of Ontario patients with cannabis-related conditions going to emergency departments or being admitted to hospitals.

Compared with others of the same age and sex who were seeking care for other reasons, research shows these patients (ages 45 to 105) had 1.5 times the risk of a dementia diagnosis within five years, and 3.9 times the risk of that for the general population.

Even after adjusting for chronic health conditions and sociodemographic factors, those seeking acute care resulting from cannabis use had a 23% higher dementia risk than patients with noncannabis-related ailments, and a 72% higher risk than the general population.

None of these studies were randomized clinical trials, the researchers pointed out; they were observational and could not ascertain causality. Some cannabis research doesn’t specify whether users are smoking, vaping, ingesting or rubbing topical cannabis on aching joints; other studies lack relevant demographic information.

“It’s very frustrating that we’re not able to provide more individual guidance on safer modes of consumption, and on amounts of use that seem lower-risk,” Myran said. “It just highlights that the rapid expansion of regular cannabis use in North America is outpacing our knowledge.”

Still, given the health vulnerabilities of older people, and the far greater potency of current cannabis products compared with the weed of their youth, he and other researchers urge caution.

“If you view cannabis as a medicine, you should be open to the idea that there are groups who probably shouldn’t use it and that there are potential adverse effects from it,” he said. “Because that is true of all medicines.”

Julie Rovner is chief Washington correspondent and host of KFF Health News’ weekly health policy news podcast, “What the Health?” A noted expert on health policy issues, Julie is the author of the critically praised reference book “Health Care Politics and Policy A to Z,” now in its third edition.

After narrowly passing in the House in May, President Donald Trump’s “One Big Beautiful Bill” has now arrived in the Senate, where Republicans are struggling to decide whether to pass it, change it, or — as Elon Musk, who recently stepped back from advising Trump, is demanding — kill it. 

Adding fuel to the fire, the Congressional Budget Office estimates the bill as written would increase the number of Americans without health insurance by nearly 11 million over the next decade. That number would grow to approximately 16 million should Republicans also not extend additional subsidies for the Affordable Care Act, which expire at year’s end. 

This week’s panelists are Julie Rovner of KFF Health News, Jessie Hellmann of CQ Roll Call, Alice Miranda Ollstein of Politico, and Lauren Weber of The Washington Post.

Among the takeaways from this week’s episode:

• Even before the CBO released estimates of how many Americans stand to lose health coverage under the House-passed budget reconciliation bill, Republicans in Washington were casting doubt on the nonpartisan office’s findings — as they did during their 2017 Affordable Care Act repeal effort.
• Responding to concerns about proposed Medicaid cuts, Iowa Sen. Joni Ernst, a Republican, this week stood behind her controversial rejoinder at a town hall that “we’re all going to die.” The remark and its public response illuminated the problematic politics Republicans face in reducing benefits on which their constituents rely — and may foreshadow campaign fights to come.
• Journalists revealed that Health and Human Services Secretary Robert F. Kennedy Jr.’s report on children’s health may have been generated at least in part by artificial intelligence. The telltale signs in the report of what are called “AI hallucinations” included citations to scientific studies that don’t exist and a garbled interpretation of the findings of other research, raising further questions about the validity of the report’s recommendations.
• And the Trump administration this week revoked Biden-era guidance on the Emergency Medical Treatment and Active Labor Act. Regardless, the underlying law instructing hospitals to care for those experiencing pregnancy emergencies still applies.

Also this week, Rovner interviews KFF Health News’ Arielle Zionts, who reported and wrote the latest “Bill of the Month” feature, about a Medicaid patient who had an emergency in another state and the big bill he got for his troubles.

Millions would lose Medicaid coverage. Millions would be left without health insurance. Signing up for health plans on the Affordable Care Act marketplaces would be harder and more expensive.

President Donald Trump’s domestic policy legislation, the One Big Beautiful Bill Act that cleared the House in May and now moves to the Senate, could also be called Obamacare Repeal Lite, its critics say. In addition to causing millions of Americans to lose their coverage under Medicaid, the health program for low-income and disabled people, the measure includes the most substantial rollback of the ACA since Trump’s Republican allies tried to pass legislation in 2017 that would have largely repealed President Barack Obama’s signature domestic accomplishment.

One difference today is that Republicans aren’t describing their legislation as a repeal of the ACA, after the 2017 effort cost them control of the House the following year. Instead, they say the bill would merely reduce “waste, fraud, and abuse” in Medicaid and other government health programs.

“In a way, this is their ACA repeal wish list without advertising it as Obamacare repeal,” said Philip Rocco, an associate professor of political science at Marquette University in Milwaukee and co-author of the book “Obamacare Wars: Federalism, State Politics, and the Affordable Care Act.”

The GOP, Rocco said, learned eight years ago that the “headline of Obamacare repeal is really bad politics.”

Democrats have tried to frame Trump’s One Big Beautiful Bill Act as an assault on Americans’ health care, just as they did with the 2017 legislation.

“They are essentially repealing parts of the Affordable Care Act,” Rep. Frank Pallone Jr. (D-N.J.) said as the House debated the measure in May. “This bill will destroy the health care system of this country.”

Nearly two-thirds of adults have a favorable view of the ACA, according to polling by KFF, a national health information nonprofit that includes KFF Health News.

In contrast, about half of people polled also say there are major problems with waste, fraud, and abuse in government health programs, including Medicaid, KFF found.

“We are not cutting Medicaid,” House Speaker Mike Johnson said May 25 on CNN’s “State of the Union,” describing the bill’s changes as affecting only immigrants living in the U.S. without authorization and “able-bodied workers” whom he claimed are on Medicaid but don’t work.

The program is “intended for the most vulnerable populations of Americans, which is pregnant women and young single mothers, the disabled, the elderly,” he said. “They are protected in what we’re doing because we’re preserving the resources for those who need it most.”

The 2025 legislation wouldn’t cut as deeply into health programs as the failed 2017 bill, which would have led to about 32 million Americans losing insurance coverage, the Congressional Budget Office estimated at the time. By contrast, the One Big Beautiful Bill Act, with provisions that affect Medicaid and ACA enrollees, would leave nearly 9 million more people without health insurance by 2034, according to the CBO.

That number rises to nearly 14 million if Congress doesn’t extend premium subsidies for Obamacare plans that were enhanced during the pandemic to help more people buy insurance on government marketplaces, the CBO says. Without congressional action, the more generous subsidies will expire at the end of the year and most ACA enrollees will see their premiums rise sharply.

The increased financial assistance led to a record 24 million people enrolled in ACA marketplace plans this year, and health insurance experts predict a large reduction without the enhanced subsidies.

Loss of those enhanced subsidies, coupled with other changes set in the House bill, will mean “the ACA will still be there, but it will be devastating for the program,” said Katie Keith, founding director of the Center for Health Policy and the Law at Georgetown University.   

Republicans argue that ACA subsidies are a separate issue from the One Big Beautiful Bill Act and accuse Democrats of conflating them.

The House-passed bill also makes a number of ACA changes, including shortening by a month the annual open enrollment period and eliminating policies from Joe Biden’s presidency that allowed many low-income people to sign up year-round.

New paperwork hurdles the House bill creates are also expected to result in people dropping or losing ACA coverage, according to the CBO.

For example, the bill would end most automatic reenrollment, which was used by more than 10 million people this year. Instead, most ACA enrollees would need to provide updated information, including on income and immigration status, to the federal and state ACA marketplaces every year, starting in August, well before open enrollment.

Studies show that additional administrative hurdles lead to people dropping coverage, said Sabrina Corlette, a research professor and co-director of the Center on Health Insurance Reforms at Georgetown University.

“Not only do people drop out of the process, but it tends to be healthier, younger, lower-income folks who drop out,” she said. “That’s dumb because they go uninsured. Also, it is bad for the insurance market.”

Supporters of the provision say it’s necessary to combat fraudulent enrollment by ensuring that ACA beneficiaries still want coverage every year or that they are not being enrolled without their permission by rogue sales agents. Most of the Medicaid coverage reductions in the bill, the CBO says, are due to new work requirements and directives for the 21 million adults added to the program since 2014 under an expansion authorized by the ACA.

One new requirement is that those beneficiaries prove their eligibility every six months, instead of once a year, the norm in most states.

That would add costs for states and probably lead to people who are still eligible falling off Medicaid, said Oregon Medicaid Director Emma Sandoe. Oregon has one of the most liberal continuous eligibility policies, allowing anyone age 6 or older to stay on for up to two years without reapplying.

Such policies help ensure people don’t fall off for paperwork reasons and reduce administrative burden for the state, Sandoe said. Requiring more frequent eligibility checks would “limit the ability of folks to get care and receive health services, and that is our primary goal,” Sandoe said.

The 2017 repeal effort was aimed at fulfilling Trump’s promises from his first presidential campaign. That’s not the case now. The health policy provisions of the House bill instead would help to offset the cost of extending about $4 trillion in tax cuts that skew toward wealthier Americans.

The Medicaid changes in the bill would reduce federal spending on the program by about $700 billion over 10 years. CBO has not yet issued an estimate of how much the ACA provisions would save.

Timothy McBride, a health economist at Washington University in St. Louis, said Republican efforts to make it harder for what they term “able-bodied” adults to get Medicaid is code for scaling back Obamacare.

The ACA’s Medicaid expansion has been adopted by 40 states and Washington, D.C. The House bill’s work requirement and added eligibility checks are intended to drive off Medicaid enrollees who Republicans believe never should have been on the program, McBride said. Congress approved the ACA in 2010 with no Republican votes.

Most adult Medicaid enrollees under 65 are already working, studies show. Imposing requirements that people prove they’re working, or that they’re exempt from having to work, to stay on Medicaid will lead to some people losing coverage simply because they don’t fill out paperwork, researchers say.

Manatt Health estimates that about 30% of people added to Medicaid through the ACA expansion would lose coverage, or about 7 million people, said Jocelyn Guyer, senior managing director of the consulting firm.

The bill also would make it harder for people enrolled under Medicaid expansions to get care, because it requires states to charge copayments of up to $35 for some specialist services for those with incomes above the federal poverty level, which is $15,650 for an individual in 2025.

Today, copayments are rare in Medicaid, and when states charge them, they’re typically nominal, usually under $10. Studies show cost sharing in Medicaid leads to worse access to care among beneficiaries.

Christopher Pope, a senior fellow with the conservative Manhattan Institute, acknowledged that some people will lose coverage but rejected the notion that the GOP bill amounts to a full-on assault on the ACA.

He questioned the coverage reductions forecast by the CBO, saying the agency often struggles to accurately predict how states will react to changes in law. He said that some states may make it easy for enrollees to satisfy new work requirements, reducing coverage losses.

By comparison, Pope said, the ACA repeal effort from Trump’s first term a decade ago would have ended the entire Medicaid expansion. “This bill does nothing to stop the top features of Obamacare,” Pope said.

But McBride said that while the number of people losing health insurance under the GOP bill is predicted to be less than the 2017 estimates, it would still eliminate about half the ACA’s coverage gains, which brought the U.S. uninsured rate to historical lows. “It would take us backwards,” he said.

With only a single vote to spare, the House passed a controversial budget bill that includes billions of dollars in tax cuts for the wealthy, along with billions of dollars of cuts to Medicaid, the Affordable Care Act, and the food stamp program — most of which will affect those at the lower end of the income scale. But the bill faces an uncertain future in the Senate.

Meanwhile, Health and Human Services Secretary Robert F. Kennedy Jr. released a report from his commission to “Make America Healthy Again” that described threats to the health of the American public — but notably included nothing on threats from tobacco, gun violence, or a lack of health insurance.

This week’s panelists are Julie Rovner of KFF Health News, Anna Edney of Bloomberg News, Sarah Karlin-Smith of the Pink Sheet, and Alice Miranda Ollstein of Politico.

Among the takeaways from this week’s episode:

• House Republicans passed their “big, beautiful” bill 215-214 this week, with one Republican critic voting present. But the Senate may have its own “big, beautiful” rewrite. Some conservative senators who worry about federal debt are concerned that the bill is not fully paid for and would add to the budget deficit. Others, including some red-state Republicans, say the bill’s cuts to Medicaid and food assistance go too far and would hurt low-income Americans. The bill’s cuts would represent the biggest reductions to Medicaid in the program’s 60-year history.
• Many of the bill’s Medicaid cuts would come from adding work requirements. Most people receiving Medicaid already work, but such requirements in Arkansas and Georgia showed that people often lose coverage under these rules because they have trouble documenting their work hours, including because of technological problems. The nonpartisan Congressional Budget Office estimated an earlier version of the bill would reduce the number of people with Medicaid by at least 8.6 million over a decade. The requirements also could add a burden for employers. The bill’s work requirements are relatively broad and would affect people who are 19 to 64 years old. 
• People whose Medicaid coverage is canceled also would no longer qualify for ACA subsidies for marketplace plans. Medicare also would be affected, because the bill would be expected to trigger an across-the-board sequestration cut.
• The bill also would impact abortion by effectively banning it in ACA marketplace plans, which would disrupt a compromise struck in the 2010 law. And the bill would block funding for Planned Parenthood in Medicaid, although that federal money is used for other care such as cancer screenings, not abortions. In the past, the Senate parliamentarian has said that kind of provision is not allowed under budget rules, but some Republicans want to take the unusual step of overruling the parliamentarian.
• This week, FDA leaders released covid-19 vaccine recommendations in a medical journal. They plan to limit future access to the vaccines to people 65 and older and others who are at high risk of serious illness if infected, and they want to require manufacturers to do further clinical trials to show whether the vaccines benefit healthy younger people. There are questions about whether this is legal, which products would be affected, when this would take effect, and whether it’s ethical to require these studies. 
• HHS released a report on chronic disease starting in childhood. The report doesn’t include many new findings but is noteworthy in part because of what it doesn’t discuss — gun violence, the leading cause of death for children and teens in the United States; tobacco; the lack of health insurance coverage; and socioeconomic factors that affect access to healthy food.

Also this week, Rovner interviews University of California-Davis School of Law professor and abortion historian Mary Ziegler about her new book on the past and future of the “personhood” movement aimed at granting legal rights to fetuses and embryos.
