The USPSTF recommends prescribing statins for adults aged 40-75 with one or more CVD risk factors and estimated 10-year CVD risk of 10% or greater. For those aged 76 or older, the evidence is insufficient to make a recommendation. Statin use can significantly reduce CVD events and mortality in this population.

A pilot vape shop voucher scheme helped 42% of entrenched smokers quit smoking within four weeks, according to a new study. The scheme, which targeted vulnerable and disadvantaged smokers, saw improved results compared to other forms of smoking cessation support.
The prevalence of past-year quit attempts among adult smokers decreased in 2020, while nicotine replacement therapy sales dropped. This suggests that reengaging smokers who faced negative outcomes during the pandemic should be a priority for quit attempt assistance.
A study of 2,700 children in the Netherlands found a possible association between maternal smoking and suboptimal brain development among offspring. The research suggests that tobacco use during pregnancy may impact preadolescent brain development.
Climate change is intensifying Western US wildfire activity, resulting in taller smoke plumes and more aerosols injected into the atmosphere. The study models 4.6 million smoke plumes and finds that maximum plume height increased by an average of 320 ft per year in four regions, with some areas experiencing a 750 ft per year increase.

A study of 994,000 US adults found a slight decrease in current e-cigarette use between 2018 and 2020, mainly among young adults aged 18-20. Daily e-cigarette use increased, particularly among those aged 21-24, indicating greater nicotine dependence.
A recent study on adult e-cigarette use highlights the need for a more nuanced public health approach. While e-cigarettes pose risks, they also offer potential benefits for cessation of combustible cigarette smoking. Researchers suggest balancing concerns with evidence-based strategies to promote e-cigarette use as a tool for quitting.
Scientists have developed a new method to estimate the impact of black carbon from wildfires on climate change, using measurements of light absorption by coated soot particles. The study provides a more accurate way to forecast global climate change and resolves a long-standing uncertainty in earth system models.
A study found that cannabis use and daily use are more common in US states with recreational cannabis laws compared to those without. Cigarette smokers in these states have even higher rates of cannabis use.

The researchers observed a decrease in milk yield for seven consecutive days during the smoke exposure period, which persisted for another seven days post-exposure.
Children are at higher risk of health changes due to air pollution and climate change impacts, including increased asthma rates and vector-borne diseases. Caregivers can take steps to minimize exposure by making personal and family changes such as using electric cars, reducing meat consumption, and improving indoor air quality.
A UNLV study analyzed nearly 30,000 broken bone cases and found that smoking increases the risk of breaking a bone by as much as 37%. The study also found that men are more likely to experience fractures, particularly in the wrists, spine, and shoulders, due to nicotine's negative impact on bone cells and calcium absorption.
Researchers discovered that dermal contact with nicotine concentrations found in thirdhand smoke and electronic cigarette spills can impair wound healing, increase susceptibility to skin infections, and cause oxidative stress in skin cells. The study suggests that even a short exposure of 24 hours is sufficient to cause skin damage.
A nationally representative study found that menthol cigarettes increase frequency of smoking among US youth, leading to higher nicotine dependence. The study suggests a strong case for the FDA's proposed ban on menthol flavoring in cigarettes to protect young smokers.
The proposed ban on menthol cigarettes aims to address health inequities in the Black community. The Rutgers Center for Tobacco Studies has found a strong link between menthol use and higher smoking rates among young people and reduced success in quitting.
Total US cigarette retail sales declined significantly, with a -12.8% decrease in annual sales from 2015 to 2021. Cigarette prices also decreased, with a average annual price drop of $0.75 per pack.
A randomized clinical trial found that smokers who received cigarette packs with graphic warning labels hid their packs 38% more often. However, when they returned to regular packs without the labels, hiding behavior returned to baseline levels. The study suggests that graphic warnings may not be effective in reducing smoking behavior.
The study reveals disparities in receiving smoking cessation assistance based on regional differences, with some areas having significantly lower access. The research highlights the importance of addressing these disparities to ensure equitable healthcare for smokers.
