(Press-News.org) Researchers have shown that there is strong evidence that e-cigarette use may act as a gateway to cigarette smoking and other health issues in young people.
A review of reviews has revealed that there is a consistent link between e-cigarette use and later cigarette smoking, as well as potential links between vaping and a range of health issues, including asthma, mental health concerns, and drug use.
Researchers, from the University of York and the London School of Hygiene and Tropical Medicine (LSHTM), argue that more research is needed to determine whether there is a direct cause and effect, but the consistency of the findings between the studies conducted so far provide a strong case for precautionary policies, such as restricting youth access to e-cigarettes and strengthening public education efforts.
Su Golder, Associate Professor in Health Science at the University of York, said: “Our previous reviews have shown that commonly used marketing strategies for e-cigarettes on social media networks resulted in more young people vaping, and this new review looks at what happens when vaping is a regular practice.
“The consistency in the evidence is striking. Across multiple studies, young people who use e-cigarettes are more likely to smoke in the future. These findings support stronger public health measures to protect teens from the risks associated with vaping.”
Researchers not only showed an increased smoking risk, but that young people who once vaped, may go on to smoke more frequently and intensely. The review also found that vaping in young people often is followed by alcohol and marijuana use.
A number of studies showed links between e-cigarette use and asthma, coughing, and airway irritation, and experts highlighted that the associated risk of depression and suicidal thoughts in teens, needed more research to better inform on the mental health risks of vaping.
Many young people report signs of nicotine dependence, including cravings and difficulty quitting, but despite concerns about nicotine’s effects on the adolescent brain, very few reviews have examined this issue.
Dr Greg Hartwell, Clinical Assistant Professor at the London School of Hygiene Tropical Medicine, said: “Our review provides the most comprehensive picture to date on the range of risks vaping poses to young people. In particular, we found consistent evidence around transitions to smoking which of course, in turn, opens the door to the multitude of harms that conventional cigarettes bring.”
Researchers are also calling for urgent, longitudinal research into e-cigarettes and areas such as brain development, cardiovascular impacts, oral health, and dual use of e-cigarettes and tobacco.
The research is published in the journal Tobacco Control.

Youth vaping consistently linked to subsequent smoking, marijuana and alcohol use
2025-08-20
Vaping among teens and young people is consistently linked to subsequent smoking, marijuana and alcohol use, finds an overarching (umbrella) review of systematic reviews of the evidence, published online in the journal Tobacco Control.
And it’s associated with other harmful consequences, including heightened risks of asthma, cough, injuries and mental ill health as well as possibly pneumonia, bronchitis, headaches, migraine, dizziness/lightheadedness, low sperm count, and poor mouth health.
The findings reinforce policy measures to restrict sales and marketing ...
Diet rich in omega-3 fatty acids may help ward off short sightedness in children
2025-08-20
A diet rich in omega-3 fatty acids, found predominantly in fish oils, may help ward off the development of short sightedness (myopia) in children, while a high intake of saturated fats, found in foods such as butter, palm oil, and red meat, may boost the risk of the condition, finds research published online in the British Journal of Ophthalmology.
The global prevalence of myopia is rising, especially in East Asia, and it’s predicted that around half of the world’s population will be affected by 2050, note the researchers.

For apes, out of sight isn’t out of mind
2025-08-20
A series of hide-and-seek experiments with a bonobo named Kanzi shows for the first time that apes can mentally keep track of multiple familiar humans at once, even when they are out of sight.
Kanzi could also recognize caregivers from their voices alone, an ability never before tested on bonobos.
The work, led by Johns Hopkins University’s Social and Cognitive Origins Group, answers key questions about how animals manage to keep track of their groupmates and uncovers yet another aspect of human social cognition shared with our closest relatives.
“People think social intelligence is a thing that makes humans unique—that because we have to manage so many different relationships, ...
Mysterious fickle hill earthquake in Northern California may have unexpected source
2025-08-20
What lies beneath Fickle Hill in northern California? Maybe the answer to an earthquake mystery that has puzzled seismologists for decades.
The origin of the 1954 magnitude 6.5 earthquake that rattled residents around Humboldt Bay has been unclear, but a new study now suggests a surprising source: the Cascadia subduction interface.
In the Bulletin of the Seismological Society of America, a team of researchers shares the scientific sleuthing that led them to that conclusion, in a tale that combines fading paper records, modern methods and modeling, and eyewitness accounts of the event.

Boys can help break taboo around periods
2025-08-20
Teaching about periods in schools is still too focused on basic biological facts with insufficient information around how menstruation can affect a woman’s mood and wellbeing, problems associated with menstrual bleeding and the impact on physical and academic performance, concludes a new study by UCL (University College London) researchers.
The survey and focus group based research, published in the academic journal Women’s Health, also suggests that periods should be taught amongst mixed sex groups as well as single sex at both primary and ...
Illinois researchers pair nanocatalysts, food waste to reduce carbon emissions in aviation
2025-08-19
For researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign, a new avenue for reducing carbon emissions can be found on the side.
A side of salad dressing, that is.
In 2020, the United States federal government committed to achieving net-zero carbon emissions by 2050. An important step towards carbon neutrality is embracing sustainable aviation fuel (SAF), an alternative to conventional jet fuel that is made from renewable feedstocks. As part of this initiative, Grainger engineers have been hard at work creating the critical nanocatalysts for converting biocrude oil ...
New research shows how nerve cells can be protected against ALS
2025-08-19
By analyzing millions of messenger RNA molecules (mRNA) during the course of ALS, researchers at Stockholm University, in collaboration with scientists at the Paris Brain Institute and Örebro University, have identified why certain nerve cells are resistant to the disease and what happens in the sensitive nerve cells when they are affected. The study, published in the scientific journal Genome Research, focuses on a hereditary form of ALS caused by mutations in the SOD1 gene.
“We have gained a better understanding of how nerve cells can be protected against ALS. This opens up new targets ...
Timing is everything: Finding treatment windows in genetic brain disease
2025-08-19
A Yale research team has created a new computer tool that can pinpoint when exactly genes turn on and off over time during brain development — a finding that may one day help doctors identify the optimal window to deploy gene therapy treatments.
Dubbed “chronODE,” the tool uses math and machine learning to model how gene activity and chromatin (the DNA and protein mix that forms chromosomes) patterns change over time. The tool may offer a variety of applications in disease modelling and basic genomic research and perhaps lead to future therapeutic uses.
“Basically, we ...
MSU scientist partners on biofuel policy for a carbon-neutral agricultural future
2025-08-19
MSU has a satellite uplink/LTN TV studio and Comrex line for radio interviews upon request.
Why this matters:
Biofuels have long been regarded as a key tool for reducing reliance on fossil fuels, but current policies often overlook the carbon benefits of sustainable farming practices. Therefore, farmers could be rewarded for adopting practices such as no-till farming, crop rotation, cover cropping, variable rate input, precision conservation and emerging climate-smart technologies like biochar and enhanced rock weathering.
Climate-smart ...
Building blocks and quantum computers: New research leans on modularity
2025-08-19
What do children’s building blocks and quantum computing have in common? The answer is modularity. It is difficult for scientists to build quantum computers monolithically – that is, as a single large unit. Quantum computing relies on the manipulation of millions of information units called qubits, but these qubits are difficult to assemble. The solution? Finding modular ways to construct quantum computers. Like plastic children’s bricks that lock together to create larger, more intricate structures, ...
