The world is smoking less, but the tobacco epidemic is far from over. A new WHO global report shows the number of tobacco users has dropped from 1.38 billion in 2000 to 1.2 billion in 2024. Since 2010, the number of people using tobacco has dropped by 120 million – a 27% drop in relative terms. Yet, tobacco still hooks one in five adults worldwide, fuelling millions of preventable deaths every year.
“Millions of people are stopping, or not taking up, tobacco use thanks to tobacco control efforts by countries around the world,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “In response to this strong progress, the tobacco industry is fighting back with new nicotine products, aggressively targeting young people. Governments must act faster and stronger in implementing proven tobacco control policies.”
For the first time, WHO has estimated global e-cigarette use – and the numbers are alarming: more than 100 million people worldwide are now vaping. This includes:
The tobacco industry is introducing an incessant chain of new products and technologies for its aim to market tobacco addiction with not just cigarettes but also e-cigarettes, nicotine pouches, heated tobacco products among others, which all harm people’s health, and more worryingly the health of new generations, youth and adolescents.
“E-cigarettes are fuelling a new wave of nicotine addiction,” said Etienne Krug, WHO Director of Health Determinants, Promotion and Prevention Department. “They are marketed as harm reduction but, in reality, are hooking kids on nicotine earlier and risk undermining decades of progress.”
While there has been a steady decline in tobacco use for both men and women across all age-groups during 2000–2024, women have been leading the charge to quit tobacco. They hit the global reduction target for 2025 five years early, reaching the 30% milestone back in 2020. Prevalence of tobacco use among women dropped from 11% in 2010 to just 6.6% in 2024, with the number of female tobacco users falling from 277 million in 2010 to 206 million in 2024.
By contrast, men are not expected to reach the goal until 2031. Today, more than four out of five tobacco users worldwide are men, with just under 1 billion men still using tobacco. While prevalence among men has fallen from 41.4% in 2010 to 32.5% in 2024, the pace of change is too slow.
WHO is urging governments everywhere to step up tobacco control. This means fully implementing and enforcing the MPOWER package and the WHO Framework Convention on Tobacco Control, closing loopholes that allow the tobacco and nicotine industries to target children, and regulating new nicotine products like e-cigarettes. It also means raising tobacco taxes, banning advertising, and expanding cessation services so that millions more people can quit.
“Nearly 20% of adults people still use tobacco and nicotine products. We cannot let up now,” said Jeremy Farrar, WHO Assistant Director-General for Health Promotion and Disease Prevention and Care. “The world has made gains, but stronger, faster action is the only way to beat the tobacco epidemic.”
Findings of the new report titled, “WHO global report on trends in prevalence of tobacco use 2000–2024 and projections 2025–2030” are based on 2034 national surveys, covering 97% of the global population. The data underpin global reporting on SDG Target 3.a and the WHO NCD Global Action Plan, which aimed for a 30% relative reduction in tobacco use by 2025. Current progress: 27% reduction, falling short by 50 million users.
Through landmark new guidelines released today, leading reproductive health agencies are calling for a major shift in how postpartum haemorrhage (PPH) is prevented, diagnosed and treated. The recommendations highlight the urgent need for earlier detection and faster intervention – steps that could save the lives of tens of thousands of women each year.
Defined as excessive bleeding after childbirth, PPH affects millions of women annually and causes nearly 45 000 deaths, making it one of the leading causes of maternal mortality globally. Even when not fatal, it can lead to lifelong physical and mental health impacts, from major organ damage to hysterectomies, anxiety and trauma.
“Postpartum haemorrhage is the most dangerous childbirth complication since it can escalate with such alarming speed. While it is not always predictable, deaths are preventable with the right care,” said Dr Jeremy Farrar, Assistant Director-General for Health Promotion and Disease Prevention and Care. “These guidelines are designed to maximize impact where the burden is highest and resources are most limited – helping ensure more women survive childbirth and can return home safely to their families.”
Published by the World Health Organization (WHO), the International Federation of Gynecology and Obstetrics (FIGO) and the International Confederation of Midwives (ICM), the guidelines introduce new objective diagnostic criteria for detecting PPH, based on the largest study on the topic to date – also published today in The Lancet.
Many PPH cases occur without identifiable risk factors, meaning early detection and rapid response is critical. Yet in many settings, especially where healthcare resources and labour wards are overstretched, delays in treatment result in devastating consequences.
Typically, PPH has been diagnosed as a blood loss of 500 mL or more. Now, clinicians are also advised to act when the blood loss reaches 300 mL, and any abnormal vital signs have been observed. To diagnose PPH early, doctors and midwives are advised to monitor women closely after birth and use calibrated drapes – simple devices that collect and accurately quantify lost blood – so that they can act immediately when criteria are met.
The guidelines recommend the immediate deployment of the MOTIVE bundle of actions once PPH has been diagnosed. This includes:
In rare cases where bleeding continues, the guidelines recommend effective interventions such as surgery or blood transfusion to safely stabilize a woman’s condition until further treatment becomes available.
“Women affected by PPH need care that is fast, feasible, effective and drives progress towards eliminating PPH-related deaths,” said Professor Anne Beatrice Kihara, President of FIGO. “These guidelines take a proactive approach of readiness, recognition and response. They are designed to ensure real-world impact – empowering health workers to deliver the right care, at the right time, and in a wide range of contexts.”
The guidelines emphasize the importance of good antenatal and postnatal care to mitigate critical risk factors such as anaemia, which is highly prevalent in low- and lower-middle income countries. Anaemia increases the likelihood of PPH and worsens outcomes if it occurs. Recommendations for anaemic mothers include daily oral iron and folate during pregnancy and intravenous iron transfusions when rapid correction is needed, including after PPH, or, if oral therapy fails.
The publication also discourages unsafe practices such as routine episiotomies while promoting preventive techniques like perineal massage in late pregnancy, so as to reduce the likelihood of trauma and severe bleeding after birth.
During the third stage of labour, the guidelines recommend administering a quality-assured uterotonic to support uterine contraction, preferably oxytocin or heat-stable carbetocin as an alternative. If intravenous options are not available and the cold chain is unreliable, misoprostol may be used as a last resort.
“Midwives know first-hand how quickly postpartum haemorrhage can escalate and cost lives,” said Professor Jacqueline Dunkley-Bent OBE, ICM’s Chief Midwife. “These guidelines are a game-changer. But to end preventable deaths from PPH, we need more than evidence and protocols. We call on governments, health systems, donors, and partners to step up, adopt these recommendations, adopt them quickly, and invest in midwives and maternal care so that postpartum haemorrhage becomes a tragedy of the past.”
The guidelines are accompanied by a suite of training and implementation resources, developed with partners including UNFPA. These tools consist of practical modules for frontline health workers, national-level guides for introducing new practices, and simulation-based training to strengthen emergency response.
These consolidated guidelines – the first to uniquely focus on PPH – are being launched at the 2025 FIGO World Congress in Cape Town, South Africa. They are a crucial step in the implementation of the Global roadmap to combat postpartum haemorrhage between 2023 and 2030.
The guidelines contain 51 recommendations, drawing together existing and new evidence-based recommendations relevant to preventing, diagnosing and treating PPH.
A new study from WHO and the UN Special Programme on Human Reproduction (HRP) on diagnostic accuracy of indicators of serious postpartum bleeding involving over 300 000 women across 23 countries was also published today in The Lancet:

The World Health Organization (WHO) emphasizes that there is currently no conclusive scientific evidence confirming a possible link between autism and use of acetaminophen (also known as paracetamol) during pregnancy.
Globally, nearly 62 million people (1 in 127) have autism spectrum disorder, a diverse group of conditions related to development of the brain. Although awareness and diagnosis have improved in recent years, the exact causes of autism have not been established, and it is understood there are multiple factors that can be involved.
Extensive research has been undertaken over the past decade, including large-scale studies, looking into links between acetaminophen use during pregnancy and autism. At this time, no consistent association has been established.
WHO recommends that all women continue to follow advice of their doctors or health workers, who can help assess individual circumstances and recommend necessary medicines. Any medicine should be used with caution during pregnancy, especially in the first three months, and in line with advice from health professionals.
Also, a robust, extensive evidence base exists showing childhood vaccines do not cause autism. Large, high-quality studies from many countries have all reached the same conclusion. Original studies suggesting a link were flawed and have been discredited. Since 1999, independent experts advising WHO have repeatedly confirmed that vaccines—including those with thiomersal or aluminum—do not cause autism or other developmental disorders.
Childhood vaccine schedules are developed through a careful, extensive and evidence-based process involving global experts and country input. The childhood immunization schedule, carefully guided by WHO, has been adopted by all countries, and has saved at least 154 million lives over the past 50 years. The schedule remains essential for the health and wellbeing of every child and every community. These schedules have continually evolved with science and now safeguard children, adolescents and adults against 30 infectious diseases.
Every vaccine recommendation by the Strategic Advisory Group of Experts on Immunization (SAGE), an independent advisory group to WHO, is grounded in rigorous review of evidence and carefully designed to offer the best protection against serious diseases and to be delivered when most needed.
When immunization schedules are delayed or disrupted, or altered without evidence review, there is a sharp increase in the risk of infection not only for the child, but also for the wider community. Infants too young to be vaccinated and people with weakened immune systems or underlying health conditions are at greatest risk.
Autism and neurodevelopmental disorders are among priority mental health and neurological conditions being discussed at the 4th UN High-Level Meeting on NCDs and mental health this Thursday, 25 September. As a global community, we need to do more to understand the causes of autism and how best to care for and support the needs of autistic people and their families.
WHO is committed to advancing this goal working together with partners including autistic-led organizations and other organizations representing persons with lived experience. WHO also stands with people who are living with autism and their families, a dignified community entitled to evidence-based considerations free of stigma.
