Health risks of synthetic drug use in Europe still unknown – DW – 06/05/2025
An EU drug report shows synthetic substances are on an upward trend. Drugs like cathinones are now made in Europe to keep up with demand. The health risks are largely unknown.
What you need to know:
Synthetic stimulants like cathinones continue to rise in Europe
Researchers lack knowledge about the long-term health risks of synthetic drug use
Cocaine remains Europe's illicit drug of choice, and it's moving from big cities to small towns
Fentanyl and nitazene use are increasing, driven by a ban on opium poppy cultivation in Afghanistan
The European Union Drugs Agency (EUDA) monitored 1,000 new psychoactive substances at the end of 2024 and found that local drug users were increasingly consuming new forms of synthetic drugs.
This has been the dominant trend in Europe over the past 5-10 years.
But what is new is that increasing amounts of these synthetic drugs are now being produced in Europe — previously, they were largely trafficked from India, China or the Middle East.
"This is a result of the demand for taking synthetic [drugs]," said Andrew Cunningham, head of policy, crime and markets at the EUDA in Lisbon, Portugal.
Cocaine, however, is still Europe's most popular illicit stimulant drug. Imported from Latin American countries like Ecuador and Colombia, about 4.6 million Europeans used cocaine in 2024.
The report also shows more Europeans are taking multiple drugs at the same time. As in previous years, so-called polysubstance use is the leading cause of drug deaths in Europe.
The findings were published in the European Drug Report 2025 , June 5.
Why is synthetic drug use a problem?
Synthetic drug use is a major public health concern. Many synthetic substances have very high potency, and because they are relatively new and ever-evolving, scientists have not been able to track the long-term effects.
The report shows that Europeans are increasingly using cathinones, either in combination with, or instead of, amphetamines and MDMA.
Cathinones, such as 3-MMC (mephedrone), are synthetic stimulants, which have "gained recreational popularity over the past 20 years in Europe," said Jan Ramaekers, a psychopharmacologist at Maastricht University in the Netherlands.
Ramaekers said the long-term health effects of cathinones were not well known. Researchers needed to better understand consumption patterns among users: What is a "normal" dose? How does it range? What is lethal?
"We need controlled studies with 3-MMC in these 'normal' dose ranges that focus on health risks, but also on potential health benefits," said Ramaekers.
Most cathinones were imported from India and China, primarily through the Netherlands. But production has steadily moved to Central Asia and Europe, "influenced by the Ukraine war," said Cunningham.

Cocaine spreading from cities to smaller towns
A significant amount of global cocaine product ends up in Europe.
For the seventh year in a row, record quantities of cocaine were seized by EU countries, amounting to 419 tons in 2023, up from 323 tons in 2022.
"It's a very significant amount considering global cocaine production is estimated at 2,600 tons per year," he said.
But it's not just cocaine: Wastewater analysis in 128 European cities found overall increases in cocaine, but also MDMA and amphetamine use in 2024.
The analysis suggests that urban patterns of drug use in big cities may be spreading to smaller towns.
Cunningham, whose team tracks the effects of geopolitical situations on Europe's drug market, said most of Europe's cocaine (70%) comes from Colombia.
"Global [cocaine] production is up every year since 2016 after the Colombian government made a [peace] deal with FARC," he said. FARC, also known as the Revolutionary Armed Forces of Colombia, were a Marxist militant group, suspected of involvement in illicit drug trade.
Large seizures in Europe's ports show drug traffickers continue to smuggle the drug in from the sea. In 2024, Spain reported its largest ever seizure of cocaine (13 tons), concealed in bananas originating in Ecuador.

Deadly synthetic opioids on the rise
The EUDA report estimates there were 7,500 drug-induced deaths in Europe in 2023, the majority of which were due to opioid drugs.
Fake medicines containing synthetic opiates called nitazenes increased in at least 12 European countries in 2024.
Some nitazene compounds are even stronger than fentanyl, which itself is 50 times stronger than heroin and has an extremely high risk of overdose.
Synthetic opioids have been a major issue in the US for years, but the report shows they are a growing problem on the European drug market, too.
"We fear an increase in synthetic opioids, such as fentanyl and nitazenes, on the illegal drug market, particularly as a result of the ban on opium poppy cultivation in Afghanistan," said Daniel Deimel, an addiction expert at Nuremberg Technical University, Germany.
Fentanyl, America's silent killer

In recent months, there has been an increase in overdose clusters in Europe, which, Deimel said, may be a result of people mixing synthetic opioids with heroin.
"Tests in drug consumption rooms in Germany have shown evidence of fentanyl or nitazene in heroin. If these substances become more common, the number of overdoses and fatal overdoses is likely to increase," said Deimel.
Drug seizures in Europe have found nitazenes in fake prescription drugs, mimicking oxycodone or benzodiazepines bought on the illegal drug market.
These fake pills have much higher potency and carry a significant risk of drug poisoning and overdose, especially as people do not know the drugs they are taking contain nitazenes.
The EUDA report shows authorities seized 10 kilograms of nitazenes powder in 2023 — potentially sufficient to make millions of pills containing enough nitazenes to cause an overdose.
Many experts are calling for more drug checking services to detect which substances are circulating on the drug scene. This allows public warnings to be issued when dangerous compounds are found in substances.

Fecal transplants: Study is a 'wake-up call' for the field – DW – 06/06/2025
They are hailed as a promising method to restore gut microbiomes, but a study suggests fecal transplants may bring unintended health risks. Fecal microbial transplants (FMTs) can be traced back to the 4th Century, but it is only since their approval by the US Food and Drug Administration in past decade that the procedure has entered wide practice. They have been hailed as a treatment for Clostridium difficile or a common bacterial infection that can cause inflammation and gastrointestinal issues. The FDA first approved FMTs as a treatment for in 2013 and approved the first drug for FMT treatment in 2022. Some think FMTs may also be an option for treating Crohn's disease— a chronic autoimmune condition — ulcerative colitis and irritable bowel disorder. But researchers warned in a study published June 6, 2025, that FMTs may introduce microbes that could hijack the host environment to suit their needs and thrive, potentially introducing new health risks. The study, which was performed in mice, human tissue samples and with a small volunteer group, found "mismatches" between the donor fecal matter and destination gut environment could have unintended consequences on the recipient's immune and metabolic function. "Even a single FMT will cause a change in the host-microbe relationships in these very different regions of the bowel that may be very difficult to reverse," said Eugene Chang, the study's senior author and a professor of medicine at the University of Chicago, US, in a press statement. How does a fecal transplant work? Every human has a unique mix of microbes in their gastrointestinal tract — the gut. This includes trillions of bacteria, fungi, viruses and other microorganisms that perform biological duties within the body. Collectively, this collection of microbes is called gut flora. For some people, this ecosystem of microbes is disrupted by infections, autoimmune issues and other problems. This disrupted state is called gut dysbiosis. FMT donors need to meet a range of requirements: For instance, they must be free of blood-related infections, such as hepatitis and HIV, and they cannot have gut issues themselves. Doctors usually perform a colonoscopy to extract the donor's stool and, after further preparation, insert the donor microbes via a long tube into the recipient's gut. How does a Fecal Microbiota Transplant work? To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Colonizing the colon In the study, microbes were taken from three separate regions of the small and large intensities and implanted into mice recipients. Each batch of newly introduced gut flora appeared to take over — or, as described by the researchers, "terraform" — the entire intestinal tract of each mouse, rather than simply occupying the same region they originated from in the donor's gut. The colonizing microbes also transformed genes and proteins in the tissues of the recipient mice to make a more accommodating environment — even at a microbial level, these introduced species appeared to thrive. An assessment in seven human volunteers over a month also found high levels of microbe colonization in the small intestine. Because this caused modifications to immune and metabolic functions, the researchers say greater care should be given to designing fecal transplants that use specific, targeted microbes for the intestines. The gut is not only for digestion To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video A 'wake-up call' for the FMT field The study's lead author, Orlando DeLeon, University of Chicago, said it was a "wake-up call to the field that maybe we shouldn't willy-nilly put large bowel microbes into different parts of the intestine that shouldn't be there." OMT — omni microbial transplantation — administers a batch of good gut flora as a pill or through endoscopy, targeting specific intestinal regions with "matched" microbes. DeLeon said it's a better way forward for fecal transplants. "The microbes that were supposed to be there are better suited for it," said DeLeon, "so they're more naturally going to fill it even in the presence of other microbes." DW approached the research group for further comment but did not receive a response in time for publication. Ed Kuijper, an expert at the Leiden University Medical Centre, Netherlands, who was not involved in the study, told DW via email that the research "clearly demonstrates that FMT […] affects the microbiota composition throughout the entire intestinal tract, in both humans and mice." But Kuijper said he had concerns with the conclusion that FMT leads to "microbiota mismatches" and "unintended consequences" in various regions of the intestinal tract. Just as the research team acknowledged the limitations of only investigating seven human subjects over a month, Kuijper said a more extensive assessment in patients would be important to conclusively assess the potential negative health outcomes of fecal transplants. "A more appropriate conclusion would be that FMT induces changes in both the small and large intestines in mice, with systemic effects that vary depending on the region affected. It remains unclear if these changes persist in humans." In Europe, an inter-organization group called EurFMT exchanges research and information, and maintains a continental registry for patient follow-up. Edited by: Zulfikar Abbany

Japan's ispace fails second lunar landing mission – DW – 06/06/2025
Japanese startup failed to land its unmanned Resilience craft on the moon. The mission was aborted as it was likely the craft had crashed after losing contact. Japan'sprivate moon mission was aborted on Friday after it was presumed that the unmanned Resilience spacecraft had crashed. Tokyo-based startup ispace had launched the mission in hopes of becoming the first private company outside the United States to achieve a controlled lunar landing. Lunar lander crashed into moon The Resilience spacecraft had begun its final descent, successfully firing its main engine "as planned to begin deceleration," ispace said. Mission control reported that the craft's position was "nearly vertical," but contact was then lost. ispace stated that the spacecraft had likely failed to decelerate sufficiently to reach the speed required for a soft lunar landing. "Based on the currently available data... it is currently assumed that the lander likely performed a hard landing. It is unlikely that communication with the lander will be restored, so it has been decided to conclude the mission," ispace said in a statement. Before signing off, the livestream announcers said, "never quit the lunar quest."

Image: Manami Yamada/REUTERS "Expectations for ispace will not waver," Japanese Prime Minister Shigeru Ishiba posted on X. Second failed attempt Two years ago, another lunar missionby the company had also ended in a crash. CEO Takeshi Hakamada told reporters he took the second failed attempt "seriously" and intended to use the outcome to inform future missions. He said they had a "strong will to move on, although we have to carefully analyze what happened." Resilience carried a four-wheeled rover built by ispace's Luxembourg subsidiary, along with five external payloads valued at a total of $16 million. The planned landing site was Mare Frigoris, a plain about 900 km (560 miles) from the moon's north pole. Lunar landings remain challenging due to the moon's rugged terrain. To date, only five nations have successfully achieved soft lunar landings: Russia, US, China, India and Japan. Private companies have recently entered the race to the moon, and ispace would have been the third such company to achieve it. The mission wanted to collect two lunar soil samples and sell them to NASA for $5,000 (€4373). In January, Resilience shared a SpaceX rocket launch with Firefly's Blue Ghost lander, which touched down successfully in March. A moon landing attempt by US-based company Intuitive Machines failed in March this year.
