TREASURE ISLAND, Fla. — Andrew McClave Jr. loved to lift weights. The 6-foot-4-inch bartender resembled a bodybuilder and once posed for a photo flexing his muscles with former pro wrestler Hulk Hogan.

“He was extremely dedicated to it,” said his father, Andrew McClave Sr., “to the point where it was almost like he missed his medication if he didn’t go.”

But the hobby took its toll. According to a police report, a friend told the Treasure Island Police Department that McClave, 36, suffered from back problems and took unprescribed pills to reduce the pain.

In late 2022, the friend discovered McClave in bed. He had no pulse. A medical examiner determined he had a fatal amount of fentanyl, cocaine, and xylazine, a veterinary tranquilizer used to sedate horses, in his system, an autopsy report said. Heart disease was listed as a contributing factor.

McClave is among more than 260 people across Florida who died in one year from accidental overdoses involving xylazine, according to a Tampa Bay Times analysis of medical examiner data from 2022, the first year state officials began tracking the substance. Numbers for 2023 haven’t been published.

The death toll reflects xylazine’s spread into the nation’s illicit drug supply. Federal regulators approved the tranquilizer for animals in the early 1970s and it’s used to sedate horses for procedures like oral exams and colic treatment, said Todd Holbrook, an equine medicine specialist at the University of Florida. Reports of people using xylazine emerged in Philadelphia, then the drug spread south and west.

What’s not clear is exactly what role the sedative plays in overdose deaths, because the Florida data shows no one fatally overdosed on xylazine alone. The painkiller fentanyl was partly to blame in all but two cases in which the veterinary drug was included as a cause of death, according to the Times analysis. Cocaine or alcohol played roles in the cases in which fentanyl was not involved.

Fentanyl is generally the “800-pound gorilla,” according to Lewis Nelson, chair of the emergency medicine department at Rutgers New Jersey Medical School, and xylazine may increase the risk of overdose, though not substantially.

But xylazine appears to complicate the response to opioid overdoses when they do happen and makes it harder to save people. Xylazine can slow breathing to dangerous levels, according to federal health officials, and it doesn’t respond to the overdose reversal drug naloxone, often known by the brand name Narcan. Part of the problem is that many people may not know they are taking the horse tranquilizer when they use other drugs, so they aren’t aware of the additional risks.

Lawmakers in Tallahassee made xylazine a Schedule 1 drug like heroin or ecstasy in 2016, and several other states including Pennsylvania, Ohio, and West Virginia have taken action to classify it as a scheduled substance, too. But it’s not prohibited at the federal level. Legislation pending in Congress would criminalize illicit xylazine use nationwide.

The White House in April designated the combination of fentanyl and xylazine, often called “tranq dope,” as an emerging drug threat. A study of 20 states and Washington, D.C., found that overdose deaths attributed to both illicit fentanyl and xylazine exploded from January 2019 to June 2022, jumping from 12 a month to 188.

“We really need to continue to be proactive,” said Amanda Bonham-Lovett, program director of a syringe exchange in St. Petersburg, “and not wait until this is a bigger issue.”

‘A Good Business Model’

There are few definitive answers about why xylazine use has spread — and its impact on people who consume it.

The U.S. Drug Enforcement Administration in September said the tranquilizer is entering the country in several ways, including from China and in fentanyl brought across the southwestern border. The Florida attorney general’s office is prosecuting an Orange County drug trafficking case that involves xylazine from a New Jersey supplier.

Bonham-Lovett, who runs IDEA Exchange Pinellas, the county’s anonymous needle exchange, said some local residents who use drugs are not seeking out xylazine — and don’t know they’re consuming it.

One theory is that dealers are mixing xylazine into fentanyl because it’s cheap and also affects the brain, Nelson said.

“It’s conceivable that if you add a psychoactive agent to the fentanyl, you can put less fentanyl in and still get the same kick,” he said. “It’s a good business model.”

In Florida, men accounted for three-quarters of fatal overdoses involving xylazine, according to the Times analysis. Almost 80% of those who died were white. The median age was 42.

Counties on Florida’s eastern coast saw the highest death tolls. Duval County topped the list with 46 overdoses. Tampa Bay recorded 19 fatalities.

Cocaine was also a cause in more than 80 cases, including McClave’s, the Times found. The DEA in 2018 warned of cocaine laced with fentanyl in Florida.

In McClave’s case, Treasure Island police found what appeared to be marijuana and a small plastic bag with white residue in his room, according to a police report. His family still questions how he took the powerful drugs and is grappling with his death.

He was an avid fisherman, catching snook and grouper in the Gulf of Mexico, said his sister, Ashley McClave. He dreamed of being a charter boat captain.

“I feel like I’ve lost everything,” his sister said. “My son won’t be able to learn how to fish from his uncle.”

Mysterious Wounds

Another vexing challenge for health officials is the link between chronic xylazine use and open wounds.

The wounds are showing up across Tampa Bay, needle exchange leaders said. The telltale sign is blackened, crusty tissue, Bonham-Lovett said. Though the injuries may start small — the size of a dime — they can grow and “take over someone’s whole limb,” she said.

Even those who snort fentanyl, instead of injecting it, can develop them. The phenomenon is unexplained, Nelson said, and is not seen in animals.

IDEA Exchange Pinellas has recorded at least 10 cases since opening last February, Bonham-Lovett said, and has a successful treatment plan. Staffers wash the wounds with soap and water, then dress them.

One person required hospitalization partly due to xylazine’s effects, Bonham-Lovett said. A 31-year-old St. Petersburg woman, who asked not to be named due to concerns over her safety and the stigma of drug use, said she was admitted to St. Anthony’s Hospital in 2023. The woman, who said she uses fentanyl daily, had a years-long staph infection resistant to some antibiotics, and a wound recently spread across half her thigh.

The woman hadn’t heard of xylazine until IDEA Exchange Pinellas told her about the drug. She’s thankful she found out in time to get care.

“I probably would have lost my leg,” she said.

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.
