A cross-sectional study in 3 US states found that directory laws did not reduce flavored e-cigarette sales, instead diverting resources away from evidence-based tobacco control strategies. The findings suggest that these laws may not be effective in reducing e-cigarette use.
A new Cochrane review finds that nicotine e-cigarettes are more effective in helping people quit smoking than conventional methods like nicotine gums and patches. The review of 80 randomized controlled trials involving 29,861 participants showed that e-cigarettes led to higher quit rates, resulting in about 4 more quitters per 100 people.
A new study finds that rain falling through wildfire smoke can deliver unusually large bursts of nitrogen, phosphorus, and potassium to ecosystems in the United States. The nutrient pulses could become an increasingly important ecological consequence of fire as wildfires become more frequent.

A new study in China finds that onetime lowdose computed tomography (LDCT) screening can significantly reduce lung cancer mortality in a non–risk based population, including individuals with no smoking history. The findings support reconsideration of current eligibility criteria.
A cohort study found that smokers with negative baseline low-dose computed tomography findings had a significantly increased long-term lung cancer risk, becoming apparent only after two years of screening. This suggests supporting extended initial screening intervals and personalized long-term monitoring based on smoking history.
Maintaining a healthy lifestyle, including a high-quality diet, moderate exercise, and low alcohol consumption, was associated with lower cardiometabolic disease risk. The study found that adhering to these healthy behaviors reduced the risk of major cardiometabolic diseases independent of medication use.
Researchers have developed a new method for cleaning oil spills using massive fire whirls, which can burn through crude oil nearly twice as fast as in-situ fire pools. The results show that fire whirls produce 40% less soot and consume up to 95% of the fuel, leaving fewer harmful particles behind.
A cohort study of 47,000 adults found that males had a 63% greater risk of all-cause mortality compared to females after adjusting for demographic and behavioral factors. The study suggests intrinsic biological factors, such as sex hormones or immune response, may contribute to these sex differences in mortality.

A longitudinal cohort study found that recreational cannabis legalization was associated with increased cannabis and electronic nicotine delivery systems use, but not a significant increase in cigarette use. The study suggests that commercialization policy should be closely monitored as retail cannabis expands.
The study reveals that many people are unaware of two crucial facts that can help reduce SIDS deaths: putting babies on their backs to sleep, and avoiding secondhand smoke in the home. The survey found that only 65% know that a baby should be put to sleep on its back, highlighting a need for increased education and awareness.
A new study led by Harvard T.H. Chan School of Public Health researchers found that fire smoke exposure can alter the immune system on a cellular level, even in healthy individuals. Exposure to particulate matter, gases, and other compounds in fire smoke was linked to changes in immune cells, inflammation, and gene expression.
A recent USC study found associations between increased exposure to wildfire smoke and heat stress during preconception and the first trimester with the odds of having a small-for-gestational-age infant. Living in a climate-vulnerable neighborhood can increase these risks, particularly for women exposed to heat stress.
US-market disposable e-cigarettes contain the artificial sweetener neotame, which is 35-65 times sweeter than aspartame. Neotame was ubiquitous in nicotine-free and nicotine-containing e-cigs.
A new study by UC Riverside researchers reveals that ultrasonic cigarettes may pose significant health risks due to the presence of harmful metals in their liquids and aerosols. The study found elevated levels of metals like arsenic and selenium in u-cigarette products, which can lead to lung diseases, organ damage, and cancer.
A cross-sectional study found a strong association between chronic cannabis use and endothelial dysfunction. The findings suggest that THC may contribute to the development of cardiovascular disease through distinct mechanisms, similar to tobacco smoking.
A study published in The Lancet Respiratory Medicine found that lung capacity develops in two phases: rapid growth during childhood and slower growth until peak lung function. Lung function starts to decline after the peak age, contrary to previous models. Persistent asthma and smoking affect lung function differently than thought.
A cross-sectional study finds a doubling in nicotine pouch past-30-day use and an increase in pouch plus e-cigarette dual use, leading to decreased exclusive e-cigarette use among US 10th and 12th graders. Prioritizing surveillance, regulation, and prevention strategies is crucial for addressing pediatric nicotine pouch use.
Exposure to high levels of smoke pollution increases hospitalizations for respiratory diseases in older adults. The study highlights the need for interventions to mitigate the health impacts of wildfire smoke exposure.
A cohort study found associations between pre-pregnancy overweight, smoking during pregnancy, and formula-feeding with adverse cardiovascular health trajectories in early childhood. The study suggests that addressing these factors through interventions may optimize cardiovascular health in children.
Cigarette smoking prevalence is expected to decrease in the US by 2035, primarily among young adults in historically high-prevalence states. This trend is likely to slow health consequences, particularly for older adults.
Scientists at Stanford University suggest reducing health implications of prescribed burns by fine-tuning three conditions: moisture content, heat intensity, and oxygen levels. This can slash PAH emissions by up to 77% and cut cancer risks from smoke exposure by over 50%.

By tweaking moisture, heat, and oxygen levels, PAH emissions can be slashed by up to 77%, cutting cancer risks from smoke exposure by over 50%.
A new study by UC Davis School of Medicine identifies four major areas of need among wildfire victims, including mental health support and health information. The research reveals that mental health needs are the most predominant health-related need at all time points.
A new study by Carnegie Mellon University researchers found that smoke from US wildfires and prescribed burns caused $200 billion in health damages in 2017, resulting in 20,000 premature deaths. Senior citizens were disproportionately affected, with Native American and Black communities experiencing the greatest harms per capita.
A cross-sectional study found wildfire smoke exposure associated with increased odds of mental health-related emergency department visits. The study suggests a possible increase in demand for mental health services during wildfire events.
A new study found that exposure to fine particulate air pollution from wildfire smoke was associated with increased visits to emergency departments for mental health conditions. The study suggests that wildfire smoke may play a direct role in worsening mental health conditions like depression, anxiety, and mood disorders.
A new study suggests that menthol in electronic cigarettes may pose risks to a developing baby, inhibiting cell growth and increasing cell death. The researchers recommend discouraging the use of mentholated e-cigarettes during pregnancy until more research is conducted.
Researchers developed a low-cost, durable DIY air cleaner that works as well as HEPA filters to clear indoor air pollutants. The Corsi-Rosenthal Box, comprising common HVAC filters, performed as well or better than comparable HEPA filters in removing particles from the air.
