Research from the Children of the 90s study at the University of Bristol found that men who started smoking before age 11 had sons with significantly higher body fat content compared to those who started smoking later. This study suggests a potential transgenerational effect of tobacco exposure on metabolic changes in the next generation.
Hundreds of agricultural fires burn across Sierra Leone, predominantly due to slash and burn agriculture. The fires, which peak in March and April, release greenhouse gases and particulates posing a threat to human health and regional climate.
A recent study by IHME found that a small number of US counties are driving declines in smoking rates, with some seeing significant drops over the past decade. These counties tend to have more progressive tobacco control policies and programs.
Research from The Netherlands found that high-potency cannabis users still take in more THC than lower potency smokers. Despite attempting to compensate by inhaling less smoke, titration efforts were only partially successful, resulting in roughly half of the THC strength being absorbed.
Researchers found a significant decrease in snuff smoke exposure among non-smokers in Spain after the implementation of tobacco control laws. The perception of being exposed to snuff smoke decreased by 36.5% at home and 25% overall, indicating smokers are restricting indoor smoking.
Researchers have found that third-hand smoke compounds can cause DNA damage and stick to it, potentially leading to cancer. The biggest risk is for babies and toddlers who are more vulnerable to environmental hazards. Removing affected items and taking steps like vacuuming and washing clothes can help reduce exposure.
A study published in Science of the Total Environment found that over half of non-smoking pregnant women (55%) are passive smokers. Exposure to tobacco smoke increases the risk of miscarriage, low birth weight, and cognitive development issues. Researchers attributed this largely to their partners' smoking at home.
Researchers created temperature maps to study how RIP bands influence cigarette burn rate and chemical composition. Temperature differences were found between RIP and regular cigarettes, potentially affecting PAH levels.
