Women warned against using ‘skinny jabs' whilst pregnant
The UK Medicines and Healthcare products Regulatory Agency (MHRA) also said women should not take weight loss drugs if they are breastfeeding or trying to get pregnant, because there isn't enough safety data to know whether the medicine could affect their baby.
'Anyone who gets pregnant while using them should speak to their healthcare professional and stop the medicine as soon as possible,' the agency said.
Meanwhile, all women taking the jabs should ensure they are using a form of contraception that works, the MHRA said.
One of the drugs, Mounjaro, may make birth control pills less effective, so the agency says women taking the jab should also use a non-oral form of contraception, like an implant or intrauterine device (IUD).
'Obesity reduces fertility in women. So, women with obesity taking GLP-1 drugs are more likely to get pregnant than before they lost weight,' Dr Channa Jayasena, a reproductive endocrinology researcher at Imperial College London, said in a statement.
'Women are advised to do all they can to prevent pregnancy while taking [these] drugs,' Jayasena added.
In the UK, women already receive these warnings when they get their prescriptions for the blockbuster jabs, which include Ozempic, Wegovy, Saxenda, and Victoza as well as Mounjaro.
The drugs, known as GLP-1 receptor agonists, work by mimicking hormones that help regulate appetites and make people feel full for longer. They have been approved to treat type 2 diabetes and obesity.
But the MHRA issued the reminder Thursday due to concerns that the drugs' growing popularity means women are buying them illegally online or at beauty salons, without seeing a doctor.
'Skinny jabs are medicines licensed to treat specific medical conditions and should not be used as aesthetic or cosmetic treatments,' Dr Alison Cave, MHRA's chief safety officer, said in a statement.
'They are not a quick fix to lose weight and have not been assessed to be safe when used in this way,' she added.
Between 'unprecedented' cocaine availability, counterfeit painkillers that contain deadly synthetic opioids, and evasive trafficking networks, Europe's drug problems are more complex than ever.
That's according to the European Union Drugs Agency (EUDA), which says illegal drugs are taking their toll across the entire bloc due to addiction, increases in gang violence, and burdened health systems.
'Today we face a fast-changing situation everywhere in Europe,' Alexis Goosdeel, the agency's executive director, told Euronews.
An estimated 7,500 people died from drug overdoses in 2023, up from about 7,100 the year before, the analysis found.
Most overdose deaths involved opioids, but the risks are changing as more people turn to synthetic drugs and use multiple substances.
EU officials called for more proactive efforts to prevent and treat addiction, rather than simply monitoring drug use, as well as increased police efforts to dismantle criminal networks that traffic drugs.
Here's what the latest data shows on illegal drug trends across the EU, Norway, and Turkey – and what health authorities are most worried about going forward.
Europe's opioid market is changing, with other substances emerging alongside long-term heroin risks.
After the Taliban took over in Afghanistan in 2021 and banned opium production the following year, European officials warned that heroin could become harder to find, prompting people to turn to dangerous fentanyl derivatives or synthetic opioids.
In 2023, authorities dismantled 14 heroin production sites in Europe, mostly in the Netherlands.
One type of synthetic opioid, called nitazenes, is already causing problems in places like Denmark and the Netherlands, where health authorities have warned that people could be buying counterfeit painkillers that actually contain nitazenes.
In 2023, the number of nitazene powders detected in Europe tripled. The drugs are so potent that even a small dose can be life-threatening.
Germany, France, Sweden, and Norway have reported clusters of overdoses linked to nitazenes, the EUDA said, while the drugs appear to be responsible for a 'significant share' of overdose deaths in Estonia and Latvia.
'What we see already is people who are buying on the internet molecules, believing that they are medicines while in fact they contain other substances,' Goosdeel said.
In the past year, about 4.6 million European adults have used cocaine, making it the bloc's most commonly used illegal stimulant.
It's also becoming more popular. In 2023, EU member states seized 419 tonnes of cocaine – marking the seventh year in a row of record seizures.
The biggest busts were in Belgium (123 tonnes), Spain (118 tonnes), and the Netherlands (59 tonnes), which are key entry points for cocaine trafficked into Europe from elsewhere in the world.
Last year, Spain seized 13 tonnes of cocaine, which were hidden in bananas from Ecuador – its largest ever haul from a single bust.
Cocaine is also developed in the EU, with authorities dismantling 34 production sites in 2023.
The competitive market is driving an uptick in cocaine-related crime and gang violence, the report found.
The EUDA expects there to be a surge of people seeking addiction treatment in the coming years, given that there tends to be a lag of about 13 years between someone's first time trying cocaine and their first time seeking treatment.
'We need to build the capacity to be prepared for treatment,' Goosdeel said, because at the moment, 'we are not ready'.
An estimated 8.4 per cent of adults – 24 million people – used cannabis in the past year, making it Europe's most commonly used illegal drug, the report found.
Cannabis seizures rose slightly in 2023 after falling the year before, the report found. The market is worth at least €12.1 billion, and is run by organised criminal groups that cultivate, traffic, and sell the drug across Europe.
Cannabis may be common, but it isn't without its health risks. It can cause or worsen chronic respiratory issues and psychotic symptoms, with long-term, regular users at higher risk.
Meanwhile, a class of drugs known as synthetic cannabinoids are a growing concern, the EUDA said.
These highly potent drugs may be added to edibles or other cannabis products without people's knowledge, raising the risk of poisoning or other health problems.
Last year, European countries detected 20 new cannabinoids, representing more than 40 per cent of the new substances identified by the EU's early warning system.
The possible health consequences of cannabinoids are 'poorly understood,' the report said. Still, they may be tied to fatal poisonings or other problems because they have such a high concentration of THC, the active ingredient in cannabis that makes people feel high.
'So yes, there is a danger,' Goosdeel said.

French left urges Macron to act over US plan to destroy contraceptives
A State Department spokesperson told AFP this week that "a preliminary decision was made to destroy certain" birth control products from "terminated Biden-era USAID contracts." The US Agency for International Development, the country's foreign aid arm, was dismantled by Donald Trump's administration when he returned to office in January, replacing former president Joe Biden. Under the plan, some $9.7 million worth of implant and IUD contraceptives stored in Belgium are reportedly set to be incinerated in France. An open letter signed by French Green leader Marine Tondelier and several female lawmakers called the US decision "an affront to the fundamental principles of solidarity, public health and sexual and reproductive rights that France is committed to defending." In the letter, they urged the French president "not to be complicit, even indirectly, in retrograde policies," saying women's contraception products such as IUDs and implants were intended for "low- and middle-income countries." "Cutting aid for contraception is shameful, destroying products that have already been manufactured and financed is even more mind-boggling," Tondelier told AFP. The Greens urged Macron to request the suspension of the plan "as part of a joint initiative with the European Commission." They also called on him to back humanitarian organisations that say they are ready to redistribute the contraception products. Separately, Mathilde Panot, parliamentary leader of the hard left France Unbowed (LFI) party, also urged Macron and Prime Minister Francois Bayrou to take action. "You have a responsibility to act to prevent this destruction, which will cost lives," she said on X. Advertisement "These resources are vital, particularly for the 218 million women who do not have access to contraceptive care." The US plan has sparked outrage from global health NGOs, with Doctors Without Borders denouncing the "callous waste." "It is unconscionable to think of these health products being burned when the demand for them globally is so great," said Rachel Milkovich of the medical charity's US office. The State Department spokesperson said the destruction will cost $167,000 and "no HIV medications or condoms are being destroyed." Doctors Without Borders says that other organisations have offered to cover the shipping and distribution costs of the supplies, but the US government declined to sign off. US lawmakers have approved slashing some $9 billion in aid primarily destined for foreign countries.

Climate change made recent European heatwave 'up to 4C hotter'
The high temperatures probably led to more heat-related deaths than would have occurred without the influence of global warming, concluded a rapid study of the episode by over a dozen researchers from five European institutions. Temperatures between late June and early July soared well above 40C in many European countries as the first heatwave of the summer broke records and triggered health warnings. The EU's climate monitor Copernicus said on Wednesday that June 2025 was the hottest on record in western Europe, where some schools and tourist sites were shuttered as the mercury soared. To assess what role climate change played, scientists compared how intense a heatwave would have been in a world that had not warmed due to burning masses of fossil fuels. Using historical weather data, they concluded the heatwave 'would have been 2 to 4C cooler' without human-induced climate change in all but one of the 12 cities studied. The added degrees greatly elevated the risk in these cities, which have a combined population of more than 30 million and include major capitals Paris, London and Madrid. 'What that does is it brings certain groups of people into more dangerous territory,' said researcher Ben Clarke, from Imperial College London, which co-led the study with the London School of Hygiene and Tropical Medicine. 'For some people it's still warm, fine weather. But for now a huge sector of the population, it's more dangerous.' The study, for the first time, also sought to estimate the death toll from the heatwave in the 12 cities studied, and how many could be attributed to climate change. Based on peer-reviewed scientific methods and established research on heat and mortality, the study concluded the heatwave likely caused about 2,300 deaths between June 23rd and July 2nd across the 12 cities studied. Advertisement An estimated 1,500, or roughly two thirds, of these deaths would not have occurred had climate change not pushed temperatures to such dangerous highs, researchers said. The authors, from research institutions in the UK, Netherlands, Denmark and Switzerland, stressed this estimate was just a snapshot of the wider heatwave, as no official count was yet available. Heatwaves are particularly dangerous for the elderly, the sick, young children, outdoor workers, and anyone exposed to high temperatures for prolonged periods without relief. The effect on health is compounded in cities, where heat is absorbed by paved surfaces and buildings, making urban areas hotter than their surroundings. Copernicus said large parts of southern Europe experienced so-called 'tropical nights' during the heatwave, when overnight temperatures don't fall low enough to let the body recover. 'An increase in heatwave temperature of just two or four degrees can mean the difference between life and death for thousands of people,' said Garyfallos Konstantinoudis, a lecturer at Imperial College London. Advertisement 'This is why heatwaves are known as silent killers. Most heat-related deaths occur in homes and hospitals out of public view and are rarely reported,' he told reporters. Authorities say it could take weeks to tally a more definitive death toll from the recent heatwave, but similar episodes have claimed tens of thousands of lives in Europe during previous summers.

Climate change made European heatwave up to 4C hotter: study
