Researchers found that e-cig liquids contain primarily free-base nicotine, the most addictive form, and often do not match label concentrations. This suggests that e-cigarettes can be just as hazardous to health as traditional tobacco products.
A two-year study by UCSF researchers found that smokers who switched to low-nicotine cigarettes were unable to quit smoking in the long term. Despite initial drops in nicotine levels, participants' smoking habits rebounded when they returned to regular cigarettes.
A Stanford University School of Medicine researcher found that six otolaryngologists were paid by tobacco companies to testify that environmental factors, not smoking, caused head and neck cancers. The physicians' testimony was scientifically invalid and part of a defense strategy to create doubt in jurors' minds.
Scientists found that flowers with both scent and nectar attract more pollinators, increasing outcrossing rates. Nectar has a larger impact on female moths laying eggs than floral scent.
The study estimates the total cost of smoking in California at $18.1 billion for 2009, down from $7.6 billion and $15.8 billion in previous years. This decline is attributed to a decrease in adult smoking prevalence and a shift towards less intense smoking habits.
The Moffitt Cancer Center has received a $3.6 million grant to investigate the long-term use of e-cigarettes as a quit-smoking strategy. The five-year study will enroll 2,500 e-cigarette users and follow them for 24 months to gather data on their effectiveness.
Leading doctors and academics call for divestment from fossil fuel companies, citing the need to prevent runaway climate change and unprecedented harm to global health. The authors argue that shareholder engagement is ineffective in switching dependence on fossil fuels with renewables.
The BMJ investigation reveals a sharp divide within the public health community regarding e-cigarettes and 'harm reduction'. Experts debate the products' potential to help smokers quit and the tobacco industry's true intentions. Some argue for collaboration with the industry, while others fear it may be a Trojan horse.
A new study finds that as smoking declines overall, remaining smokers are actually less likely to smoke and more likely to quit. The study challenges the need to promote e-cigarettes as a harm reduction strategy, suggesting that current tobacco control policies have been successful in reducing smoking prevalence.
Researchers at Georgia State University found a doubling of establishments permitting smoking in designated dining areas and outdoor spaces. The percentage of restaurants and bars allowing smoking nearly doubled from 9.1% to 17.6% between 2006 and 2012.

Research published in Tobacco Control found that including experimenters in e-cigarette prevalence studies can lead to inaccurate results. The study suggests setting a threshold of six days out of the past 30 for more accurate monitoring of population health trends. Current smokers were more likely to use e-cigarettes than former or ne...
Research suggests pyrazines, found in low tar cigarettes, can act independently of nicotine to prompt dopamine release and enhance tobacco dependence. The study calls for swift regulation of pyrazine additives to mitigate their role in nicotine addiction.
A study by Dr Erdogan Ozturk and colleagues found that smokers need more anaesthetic and painkillers compared to non-smokers, while passive smokers also require higher doses. The researchers suggest that nicotine may affect anaesthetic metabolism or desensitize pain-sensing nerve cells.

The World Health Organization recommends a 30% reduction in smoking rates by 2025. Countries must triple tobacco taxes to achieve this goal, which could save an estimated 200 million lives by the end of the century. Quitting smoking before age 40 can substantially reduce risk.
A survey of French people aged 40-75 found that many incorrectly believed low cigarette consumption was risk-free for lung cancer. Only half of current smokers considered themselves at higher risk than the average population.

The study, which followed 168 pregnant smokers, discovered that breastfeeding was the only significant predictor of change in smoking behaviors among these women.
A recent study found that some e-cigarette flavors contain high levels of chemicals that exceed recommended exposure limits and could be respiratory irritants. The research analyzed 30 products and found that 13 contained flavoring chemicals totaling more than 1% by volume, with some levels reaching as high as 3% by weight.

The report highlights the tobacco industry's expanding array of tactics to preserve profits, including aggressive marketing and legal action, which cause economic, social, and environmental harm.
Standardized packaging in Australia has been associated with increased thinking about quitting and quit attempts, as well as a decrease in appeal among school children. In contrast, retail prices for cigarettes have increased across the board, despite no evidence of an increase in illicit cigarette consumption.
Standardized packaging with large graphic health warnings was associated with increased thoughts of quitting and quit attempts among adult smokers. The study found that smokers were more likely to report intentions to try to quit, conceal their packs from view, and stub out cigarettes prematurely during the introduction period.
A comprehensive survey of toxicants in smokeless tobacco products found that hydrazine is not a prevalent contaminant. Trace levels were detected in some samples but significantly lower than previous reports.

Researchers found that e-cigarette advertising with vaping visuals increased tobacco cravings in daily and former smokers. The study suggests that unregulated e-cigarette ad spending could lead to increased exposure to smoking cues, posing a public health risk. The findings are significant, considering the growing e-cigarette ad industry.
A new study of adult daughters found that women whose parents smoked during pregnancy had an increased risk of developing diabetes mellitus. Prenatal environmental tobacco smoke exposure appears to be a modifiable risk factor for diabetes in offspring.
A Concordia University study found no significant change in home smoking habits after a Quebec ban. The presence of non-smokers and social networks were key factors in influencing quitting behavior, rather than the law itself.
A new study reveals that up to two-thirds of Australian smokers can expect to die from their habit if they don't quit, with a three times higher risk than non-smokers. The research found that smoking is a major cause of cardiovascular disease and cancer, highlighting the need for continued tobacco control efforts.
Extending UK anti-smoking legislation to parks and squares aims to support healthy lifestyle choices, particularly among young people. The proposal is based on evidence from successful smoking bans worldwide, which have been shown to reduce smoking prevalence and improve public health.

The study analyzed four popular brands of shisha tobacco and found that the levels of heavy metals in smoke were significantly higher than in water, with uranium being the most abundant metal present.
The UK government is set to introduce standardized packaging for tobacco products, building on evidence from Australia and other countries that suggests it can reduce smoking rates. Studies have shown that plain packaging may decrease the appeal of cigarette brands and increase awareness of health warnings, saving lives.
E-cigarettes have shown potential in helping smokers reduce or quit, with a significant role to play in public health. Research suggests that about 9% of smokers who used electronic cigarettes were able to stop smoking for up to one year, compared to 4% of those using nicotine-free placebos.
A suite of globally harmonized test methods is needed to measure a wider selection of toxicants in cigarette smoke. The International Organization for Standardization (ISO) must coordinate these methods to ensure reproducible and comparable results.
