The study suggests that marijuana smoking may lead to additional lung damage beyond what is seen in tobacco smokers.
A study published in Radiology found that marijuana smokers have a higher incidence of emphysema and airway inflammation compared to non-smokers and tobacco-only smokers. The researchers suggest that the unfiltered nature of marijuana smoke and longer breath-hold puffs may contribute to these findings.
Researchers found that exposure to e-cigarettes, marijuana, and tobacco led to increased scarring, decreased blood vessels, and changes in heart nerves, all contributing to an increased risk of arrhythmias. These substances can cause similar harm to the heart as traditional cigarettes.
A new study of 200,000 patients found that those who smoke cigarettes and drink heavily are more likely to experience post-surgical complications. However, talking to a health coach about drinking-related risks before surgery can help patients cut their alcohol use in half and reduce the likelihood of surgical issues.

Research found high levels of sweet and fruit-flavour chemicals in 'tobacco-flavoured' e-cigarette liquids, particularly fruity and caramellic flavour chemicals. The study suggests manufacturers are getting around regulations by using these flavour chemicals in products marketed as 'tobacco-flavoured', raising concerns about their safety.
Reducing nicotine content in cigarettes could lessen addiction and lower exposure to toxicants, increasing a smoker's chances of quitting. The study found that smokers with mood or anxiety disorders were more likely to have quit smoking after using reduced-nicotine cigarettes.

Researchers found that children are more likely to develop asthma if their father was exposed to second-hand smoke as a child. The study also shows that the risk is higher for children whose fathers smoked themselves. Epigenetic changes may be responsible for passing on this increased risk through generations.
A recent study published in the European Respiratory Journal found that children are more likely to develop asthma if their father was exposed to second-hand smoke as a child. The risk is even higher if the father went on to become a smoker himself. The researchers suggest that smoking can damage health not only for smokers and their c...

A new UCL-led study found that most British adults support stricter tobacco regulations, including banning sales near schools and raising the legal age to 21. The survey of over 1,700 adults in England and Scotland showed strong majority support for these policies.
A recent study found that Danish smokers reduced their tobacco consumption during the COVID-19 pandemic. Regular smokers bought 20% fewer cigarettes per week, while the number of quitters increased by 10%. The study suggests that the immediate consequences of smoking made during the pandemic led to a decline in cigarette purchases.

A new study by Berkeley Lab scientists reveals that thirdhand smoke can exceed health risk guidelines, putting whole households at risk. The study found that concentrations of toxic chemicals in indoor environments where cigarettes have been smoked can lead to exposure through inhalation, dust ingestion, and dermal absorption.
Researchers mapped out the brain network responsible for nicotine's negative consequences, opening the door to interventions that boost aversive effects to help people quit smoking. The discovery suggests that manipulating this network could treat nicotine dependence by inducing an acute aversive effect.

The study suggests that increased tobacco use may be one possibility of cannabis legalization.
A study by researchers at Keck School of Medicine found that flavored oral nicotine products, such as gum and gummies, are increasingly popular among US teens, with 3.4% having used them at least once and 1.7% in the past six months. The use of these products was more common among Hispanic teens, teen girls, and LGBTQ+ teens.
A new study at Columbia University's Mailman School of Public Health found that adults who use cannabis daily perceive pack a day cigarette use as less harmful than non-cannabis users. The study suggests that diminished risk perception may contribute to the observed increase in cannabis use among adults.
A new study found that COVID-19 health risks spurred more smokers to quit, with cigarette purchases declining by 20-30% and quitting rates increasing by 10 percentage points. The decline was sustained for at least a year and may lead to longer-term benefits on population health and life expectancy.

The study, which analyzed data from the American Heart Association's COVID-19 CVD Registry, also showed that young individuals are particularly at risk.
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.
A survey study of over 12,000 high school students in Cleveland found substantial reductions in tobacco product use and decreased disparities across racial and ethnic groups. The findings support the potential of raising the minimum legal age to purchase tobacco to 21 to achieve equity.
