A new study by the University of California, San Francisco, found that exposure to on-screen smoking in movies is strongly correlated with beginning or becoming established smokers among young adults aged 18-25. The research team also identified positive expectations about smoking and exposure to friends and relatives who smoke as key ...

The study suggests that quitting smoking is the most effective way to lower risk for tobacco-caused premature death.
A recent study by Oregon State University researchers suggests that tobacco company-sponsored anti-smoking advertising aimed at youths may actually increase teen smoking rates. The study found that each additional youth-targeted prevention ad viewed resulted in a 3% stronger intention among all students to smoke in the future, and that...
A large survey of male Marine Corps recruits aged 18-20 found that young men who started drinking at a young age were more likely to be risky drinkers. Risk factors also included tobacco use, rural hometown, and childhood abuse.
A study at the University at Buffalo found that synthetic cannabinoid AM-1346 can improve fertility in male smokers with poor semen quality, doubling fertilizing capacity. Researchers believe a communication imbalance between cannabinoid and cholinergic receptor systems may be responsible for nicotine-induced infertility.
A recent analysis of tobacco industry defense strategies reveals a shift in arguments as companies publicly admitted to smoking causing cancer. The study found that the industry initially claimed a lack of scientific proof and shifted its focus to mitigating factors and plaintiff free will as public admissions increased.
Dr. Stephen S. Hecht is recognized for over three decades of research on tobacco carcinogenesis, identifying nicotine's role in lung cancer formation. His work has led to the development of biomarkers for exposure to tobacco smoke and informed public policies on smoking restriction.
The Lancet calls out false allegations against Julio Frenk, Margaret Chan, and Elena Salgado, who are running for WHO Director-General. Frenk's tobacco control record is highlighted as a priority in Mexico.
A new study finds that high-tech ventilation systems are no match for secondhand smoke and may even perform worse than standard dilution ventilation. Despite proper design and operation, the systems failed to reduce exposure to carcinogenic chemicals and toxic particles in non-smoking sections.
