Some adults who take prescription medication for attention-deficit/hyperactivity disorder are required to have their urine tested for drugs several times a year. Others never are tested.

Such screenings are designed to check if ADHD patients are safely taking their pills, such as Adderall, and not selling them, taking too many, or using other drugs.

Several doctors told KHN there are varying opinions and no national standards on the role of urine testing to monitor adults who take ADHD medication. So patients face dramatically different requirements, depending on their clinics' and health insurers' policies.

"There really isn't much literature to guide you on how to do this," said Dr. Margaret Chaplin, a Connecticut psychiatrist who treats patients with ADHD, mental illnesses, or substance use disorders.

Chaplin first noticed the lack of testing standards about eight years ago, when she and colleagues proposed ways to prevent stimulant misuse in adult ADHD patients.

Her team recommended urine tests only if patients exhibit "red-flag behavior," such as appearing intoxicated, repeatedly reporting lost prescriptions, or frequently switching doctors. Some doctors and clinics make testing decisions on a patient-by-patient basis taking into account those red flags or patient history. Others apply universal policies, which may be aimed at preventing discrimination. Some insurance companies and state Medicaid systems also have testing requirements.

ADHD stimulants, opioid pain medications, and some other drugs are classified as controlled substances, which are tightly regulated because they can be addictive or misused.

ADHD patients subjected to frequent drug screens say the tests can be time-consuming and expensive. Some feel stigmatized.

A.C. Shilton felt relieved when she was diagnosed with ADHD in her mid-30s. The farmer and freelance journalist from rural Tennessee said the diagnosis explained why she felt so disorganized and forgetful, and as if her brain were a motor running all day. Shilton said her medication slows that motor down.

The 38-year-old Jamestown resident said her first doctor ordered urine tests once a year. That doctor eventually closed his practice, and Shilton said her next physician made her take a test at nearly every visit.

"You go in to get the standard of care, which is this medicine, and you're kind of treated like you're a bad person again; there's some shame associated with that," Shilton said.

She was also upset after learning office staffers were incorrect when they told her that urine testing was required by law — something that other ADHD patients posting on social media forums said had happened to them too.

Shilton said few doctors treat adult ADHD patients in her rural community. She now drives more than an hour to a different clinic, which doesn't require her to take as many drug tests.

Travis Gordon, 47, of Charlotte, North Carolina, has gone to the same ADHD clinic for more than 10 years. Gordon said he wasn't drug-tested in the first few years. Then, for several years, he had to give a urine sample every three months. During much of the covid-19 pandemic, he wasn't tested. Now, he's screened every six months.

"We shouldn’t have to feel like street criminals to get drugs that are needed for our daily success," Gordon said.

Gordon said it would make sense for doctors to order tests more frequently as they get to know new patients. But he said he doesn't understand why such testing should continue for people like him, established patients who properly take their medication.

Traci Camper, 50, of northeastern Tennessee, said she has "never even tried a cigarette," much less used illicit drugs, but her doctor has required urine tests every three months for more than 10 years. Camper said the process can be inconvenient but she's ultimately OK with the tests, especially since she lives in an area with high rates of drug abuse.

The clinics that Shilton, Gordon, and Camper went to did not respond to KHN's requests for interviews about their testing policies.

Adults are diagnosed with ADHD if they have multiple, frequent symptoms so severe they interfere with work, relationships, or other aspects of life. Treatments include therapy and medication, most often stimulants.

ADHD patients have been affected by the response to the opioid crisis, which has led to more scrutiny for all controlled medications. Some have reported trouble filling their prescriptions as drug distribution companies limit sales to certain pharmacies. Some patients, especially rural ones, could face obstacles if the federal government reverts to pre-pandemic rules that require at least one in-person appointment to receive controlled drugs via telehealth.

Chaplin said doctors who treat ADHD may feel the need to be extra vigilant with drug testing because of this increased scrutiny, or due to the risk of misuse.

An estimated 3.7 million Americans 12 or older misused prescription stimulants in 2021, and 1.5 million had a prescription stimulant use disorder, according to the National Survey on Drug Use and Health. Americans are more likely to misuse or be addicted to prescription opioids, sedatives, and tranquilizers, the agency said.

Adults with ADHD are more likely to have a substance use disorder than those without the condition, according to the Substance Abuse and Mental Health Services Administration.

Although there aren't formal standards, several health care organizations and professionals have made recommendations to prevent and detect adult ADHD stimulant misuse. Suggestions include requiring patients to sign prescription-agreement contracts and regularly checking databases that show all controlled medications each patient is buying.

Chaplin said there's little research into how effective any method is at preventing medication misuse.

A recent survey found that 42% of family physicians and 21% of college health professionals who treat adult ADHD require their patients to submit random urine drug screens.

Gordon, Camper, and some ADHD patients on social media forums said their drug screens have come at predictable intervals, instead of random ones.

Dr. Sidarth Wakhlu, a psychiatrist who specializes in treating substance use disorders at the University of Texas Southwestern Medical Center in Dallas, said some of his patients also have ADHD. He suggests drug-testing most ADHD patients once or twice a year. For "someone who has no addiction history, has no red flags, every three months is an overkill," he said.

The cost of drug testing is as variable as the frequency.

For example, Dr. Michael Fingerhood at Johns Hopkins University uses urine tests that cost as little as $60 before insurance. Fingerhood makes testing decisions case by case for patients who take controlled substances to treat ADHD, pain, or opioid addiction.

Gordon used to pay $110 for each of his tests when he had insurance his doctor did not accept. Shilton's insurance was billed $545 for a test. Shilton said she complained to a nurse who said, in the future, she could use a less expensive test.

Shilton said she replied, "Well, why aren't we doing that to begin with? Why are we doing this extremely fancy drug testing?"

Wakhlu said the more expensive urine tests can identify specific types and quantities of drugs. Such tests are usually used to confirm the results of initial, less pricey tests, according to the Centers for Disease Control and Prevention.

Wakhlu said that when test results show a patient might be misusing stimulants, doctors should initiate a non-accusatory conversation to discuss the results and, if needed, offer help. He also said it's important to emphasize safety, such as how taking too much ADHD medication or combining it with other stimulants, such as methamphetamine, can be dangerous.

Stanley Cup playoffs daily: Senators on the brink, while Avs, Knights, Bolts try to punch back

All but one NHL team will end the season on a bitter note, as there can be only one Stanley Cup champion. But on Saturday, we could have our very first playoff elimination of the 2025 playoffs.

The Ottawa Senators are on the brink heading into Saturday’s game. Despite taking the heavily favored Toronto Maple Leafs to overtime twice in a row, the Atlantic Division champs have scored the game winner each time in the extra session. Can the Senators win one in front of the home crowd to extend the series to five games?

Elsewhere in the Atlantic bracket, the Florida Panthers won both of the first two games in the Tampa Bay Lightning‘s building. Will this be a shorter series than many expected? And out West, the Minnesota Wild will look to extend their shocking series lead over the Vegas Golden Knights, and the Clash of the Western Titans continues in the Centennial State, as the Colorado Avalanche look to even things up with the Dallas Stars.

Read on for game previews with statistical insights from ESPN Research, recaps of what went down in Friday’s games, and the Three Stars of Friday Night from Arda Öcal.

Matchup notes

Tampa Bay Lightning at Florida Panthers
Game 3 (FLA leads 2-0) | 1 p.m. ET | TBS

Having served his suspension for performance-enhancing substances, Panthers defenseman Aaron Ekblad is eligible to return for this game. The well-rounded blueliner skated 23:30 per game during the regular season, scoring three goals and 30 assists in 56 games.

The Panthers have another defenseman who has been delivering this postseason; Nate Schmidt scored a goal in Games 1 and 2, becoming the first defenseman in franchise history with two game-winning goals in a single postseason — and they’re only two games in!

All eyes will be on the status of Aleksander Barkov, who was knocked out of Game 2 via a hit from Brandon Hagel; Hagel was assessed a five-minute major penalty for the play and suspended for Game 3.

Tampa Bay needs its stars and its scoring depth to get rolling to charge back into this series, with just two goals total in two games. Goaltender Andrei Vasilevskiy has not been up to his typical, superhuman standards thus far, allowing seven goals on 39 shots (.821 save percentage).

In Stanley Cup playoff history, teams that start 2-0 in a best-of-seven series have won 86% of the time; that number rises to 98% if a team starts 3-0.

Vegas Golden Knights at Minnesota Wild
Game 4 (MIN leads 2-1) | 4 p.m. ET | TBS

If nothing else, this series has been a unique one from a starting-time perspective; each of the first four games will have had a different scheduled start time once the puck is dropped Saturday — 10 p.m. ET for Game 1, 11 p.m. ET for Game 2, 9 p.m. ET for Game 3 and 4 p.m. ET for this one.

Most observers didn’t believe the Wild were going to win this series. Nor did many predict that Minnesota players would be all over the scoring leaderboard midway through Round 1. Kirill Kaprizov is tied for the playoff scoring lead with Adrian Kempe and Cam Fowler (seven points), and is tied with teammate Matt Boldy for the goal-scoring lead, with four. The current playoff assists leader? Wild blueliner Jared Spurgeon.

This has been an uncharacteristically rough opening round for Adin Hill. He’s allowed 10 goals on 57 shots, generating a .825 save percentage and 3.78 goals-against average. Those rates were .932 and 2.17, respectively, in Hill’s 16 games played during the Knights’ 2023 Stanley Cup run.

While “Playoff” Tomas Hertl has shown up this series — to the tune of two goals and an assist — some of the Knights’ other offensive standbys have been quiet. Jack Eichel, Mark Stone and Ivan Barbashev — who combined for 212 points in the regular season — all have a goose egg thus far.

Toronto Maple Leafs at Ottawa Senators
Game 4 (TOR leads 3-0) | 7 p.m. ET | TBS

The Maple Leafs have been led by a consistently strong performance of their Core Four of Auston Matthews, Mitch Marner, William Nylander and John Tavares; the quartet leads Toronto in scoring through three games. Perhaps a narrative is being rewritten before our eyes, after years of playoff disappointment for that group?

One specific area where Toronto has been dominant is the power play; their 55.6% conversion rate is tops in the league this postseason (and makes up, somewhat, for a penalty kill that is just 77.8% effective).

The Senators have had five different goal scorers this series, including Brady Tkachuk, who has been giving his all in his first playoff experience. Ottawa’s captain has two goals — and four penalty minutes, as he has kept himself in the mix whenever the action has gotten rowdier.

Will Ottawa stick with Linus Ullmark in goal for Game 4? The veteran has an .815 save percentage through the first three games — and an .874 mark in his postseason career.

Dallas Stars at Colorado Avalanche
Game 4 (DAL leads 2-1) | 9:30 p.m. ET | TBS

Game 3 was all about the return of Avalanche captain Gabriel Landeskog after an absence of 1,032 days. Landeskog skated 13:16 in the game, but did not record a point or a shot on goal.

While other teams are generating historic numbers on the power play this postseason, the Avs have struggled to a 15.4% conversion rate (fourth worst). This is in stark contrast to the regular season, when the Avs’ 24.8% rate was eighth in the league.

Tyler Seguin‘s overtime goal sealed the deal for Dallas in Game 3. it was just the second OT game winner in his career, after a span of 13 years (April 22, 2012).

The other good news on the Dallas front is that Mikko Rantanen — former Av, who was acquired on March 7 — finally picked up his first point of the series, an assist on the OT game winner. Have the floodgates opened?


Arda’s three stars from Friday night

1. The Oilers-Kings series
LA up 2-1 | 30 goals in three games

The first three games have been bonkers. Game 1 almost had an all-timer comeback, then the Kings rocked Edmonton in Game 2, while Game 3 saw multiple lead changes, quick back-to-back goals, a failed coaches challenge by L.A. on an Edmonton goal — which led to an Oilers’ power-play goal to take the lead. Just incredible.

Nemec scored the overtime winner in Newark to win the game for the Devils over the Canes — and avoid going down 0-3 in the series. This came after stints in the AHL this season, and being a healthy scratch earlier in the series.

“Goal” Caufield had a goal and an assist in Montreal’s emphatic 6-3 win over Washington in Game 3.

Friday’s scores

The Bell Centre was electric for the Canadiens’ first home game in quite some time — and the fans were sent home quite happy on Friday night after a wild game. The two teams traded goals through most of the first two periods before Cole Caufield put Montreal up one at the end of the second — and a brawl ensued that spilled into the Washington bench. Although Alex Ovechkin scored 2:39 into the third to tie the game 3-3, the Habs poured it on thereafter with three straight goals, sending the “Olé!” chants to unforeseen decibel levels. Recap.

Down 0-2 in the series, the Devils went up 2-0 in their first game back home, on goals from Nico Hischier and Dawson Mercer. But a pair of third-period, power-play goals — from Seth Jarvis and Sebastian Aho — knotted things up, and the game went to overtime. Scoreless after one extra period, the game was ended by Simon Nemec, the second overall pick in the 2022 draft, who had been a healthy scratch previously in the series. Recap.

It takes a full-team effort to get up off the proverbial canvas when down 0-2 in a series, and that’s just what the Oilers got on Friday. Ten different Oilers hit the scoresheet in this one, including superstars like Connor McDavid, Leon Draisaitl and Evan Bouchard, as well players further down the lineup like Connor Brown and Evander Kane. The Oilers also made the switch in goal to Calvin Pickard for this game, and he responded with 24 saves on 28 shots. On the Kings’ side, Adrian Kempe had his fourth goal and fifth assist of the playoffs, putting him into first in the points race and tied for first in the goals race. Recap.

Who was at the Pope's funeral - and who wasn't

The Pope’s funeral is taking place today at St Peter’s Basilica at the Vatican.

A pope’s funeral traditionally brings world leaders together, and several were in attendance.

Watch full coverage of the Pope’s funeral live on Sky News from 8am

Here’s a look at the list.

The Prince of Wales attended the funeral of Pope Francis on behalf of the King.

The King was in Rome with Queen Camilla earlier this month, and met the pontiff at the Vatican.

The trip came just a week-and-a-half after Buckingham Palace confirmed the King had been taken to hospital following side effects related to his ongoing cancer treatment.

Number 10 confirmed the prime minister received an invite and so he attended the ceremony.

Speaking on Tuesday, Sir Keir said there had been “an outpouring of grief and love” for the Pope.

He added: “I think it reflects the high esteem in which he was held, not just by millions and millions of Catholics, but by many others, across the world, myself included.”

Trump pays respects to Pope

The US president was one of the first to confirm he would be flying to Rome, adding he would be joined by first lady Melania Trump.

Writing on his social media platform Truth Social on Monday, he said: “Melania and I will be going to the funeral of Pope Francis, in Rome. We look forward to being there!”

The Pope had been critical of Mr Trump at times during his tenure.

In January, he said it would be a “disgrace” if the president went ahead with his crackdown on immigration, telling an Italian television station: “It would make the migrants, who have nothing, pay the unpaid bill.

“It doesn’t work. You don’t resolve problems this way.”

The president of Pope Francis’s native Argentina was also at the ceremony, despite having launched insults at Francis in recent years.

Before taking office in December 2023, the far-right politician called him “an imbecile, the representative of evil on Earth”.

Mr Milei alluded to their “differences” in his tribute to the late Pope, writing: “It is with profound sorrow that I learned this sad morning that Pope Francis, Jorge Bergoglio, passed away today and is now resting in peace.

“Despite differences that seem minor today, having been able to know him in his goodness and wisdom was a true honour for me.”

Joe Biden

The Brazilian president and first lady Janja Lula da Silva were also at the funeral.

Brazil had also declared a seven-day mourning period for the Pope.

“Humanity is today losing a voice of respect and welcome for others,” the president said in his tribute.

“Pope Francis lived and propagated in his daily life the love, tolerance and solidarity that are the basis of Christian
teachings.”

The EU Commission President confirmed she was attending after calling Francis a worldwide inspiration.

“He inspired millions, far beyond the Catholic Church, with his humility and love so pure for the less fortunate,” she said in her tribute.

Council President Antonio Costa, Parliament President Roberta Metsola was also expected to be in attendance.

Who was not there?

Vladimir Putin

The Russian president did not attend the funeral.

But the controversial leader paid tribute to the Pope, writing a message to Cardinal Kevin Farrell, who is interim chief of the Catholic Church.

“Please accept my most sincere condolences on the passing of His Holiness Pope Francis,” Mr Putin said.

“Throughout the years of his pontificate, he actively promoted the development of dialogue between the Russian
Orthodox and Roman Catholic churches, as well as constructive cooperation between Russia and the Holy See.”

Benjamin Netanyahu

Israeli Prime Minister Benjamin Netanyahu also did not attend the ceremony, with the country’s ambassador Yaron Sideman going instead.

The Jewish state and the Vatican have had strong relations in the past, with Israel sending a presidential delegation to the funeral of Pope John Paul II in 2005, and Pope Francis visiting Israel in 2014.

But their relationship has deteriorated since the start of the war in Gaza.

A month after the conflict started in 2023, a dispute broke out over whether Pope Francis had used the word “genocide” to describe events in Gaza. Palestinians who met with him said he did, but the Vatican said he did not.

The Pope met relatives of Israeli hostages on the same day.

Israeli officials have since lobbied the Vatican to be more forceful in its condemnation of Hamas.

In January, the Pope called the humanitarian situation in Gaza “shameful”, prompting criticism from Rome’s chief rabbi, Riccardo Di Segni, who accused Francis of “selective indignation”.

Rabbi Di Segni said he would be attending the funeral, despite it taking place on the Jewish sabbath.

Was there a seating plan?

The seats were assigned in advance, with the heads of state sitting in French alphabetical order based on their country’s name, rather than on the individual’s.

This applied to everyone apart from the presidents of Italy and Argentina, who got the best seats because the Pope lived in Italy and was an Argentinian native.

Super Earths are Quite Common Outside the Solar System, New Study Reveals

A team of international astronomers, led by Weicheng Zang from the Centre for Astrophysics | Harvard & Smithsonian (Cfa), had announced the discovery of a planet whose size is twice that of Earth, and orbits around its star at a distance farther out than Saturn. These findings reveal how planets differ from our existing solar system. The discovery was first published in the Journal Science on April 25, 2025. Scientists fetched this data from the Korea Microlensing Telescope Network (KMTNet), also known as the largest microlensing survey to date.

This Super Earth, called a planet due to its size being bigger than Earth but smaller than Neptune, is more significant as it is a large study where the masses of many planets have been measured relative to the stars that they orbit. As per physics.org, the team of researchers found fresh information about the number of planets that surround the Milky Way.

Study by KMTNet

According to the study conducted using Korean Microlensing data in which light from faraway objects is amplified through the use of an interfering body, called a planet. This technique is very effective for finding planets at a far distance, between Earth and Saturn’s orbit.

This study is considered to be large for its kind because there are about three times more planets, including planets that are eight times smaller than the previous planets found with the help of microlensing. Shude Mao, a professor, said that the current data gives a hint of how cold planets are formed. With the help of KMTNet data, we can know how these planets were formed and evolved. KMTNet has three telescopes in South Africa, Chile and Australia.

Understanding the Exoplanets

Such studies show that the other systems can have a small, medium and large variety of planets in Earth’s orbit. CFA-led research suggests that there can be more Super Earth Planets in other solar systems’ outer regions. Jennifer Yee says that there is a possibility that outside the Earth’s trajectory, other galaxies may have more such planets that are bigger than Earth’s size yet smaller than Neptune.

Findings and Implications

Youn Kii Jung, who operates KMTNet, says that in Jupiter-like orbits, the other planetary systems may not be similar to ours. Scientists will try to determine how many such planets exist. A study indicates that there are at least as many super-Earths as there are Neptune-sized planets in the universe.
