Introduction: The tobacco industry has a long history of manipulating science to conceal the harms of its products. As part of its proclaimed transformation, the world's largest tobacco company, Philip Morris International (PMI), states it conducts "transparent science". This paper uses recently leaked documents from PMI and its Japanese affiliate, Philip Morris Japan (PMJ), to examine its contemporary scientific practices.
In 2012, the U.S. Food & Drug Administration (FDA) published an established list of 93 harmful and potentially harmful constituents (HPHCs) targeting four tobacco product types (cigarettes, cigarette tobacco, roll-your-own tobacco, smokeless tobacco).
Background and aims: The use of e-cigarettes may influence later smoking uptake in young people. Evidence and gap maps (EGMs) are interactive on-line tools that display the evidence and gaps in a specific area of policy or research. The aim of this study was to map clusters and gaps in evidence exploring the relationship between e-cigarette use or availability and subsequent combustible tobacco use in people aged < 30 years.
Infertility is intricately linked with alterations in circadian rhythms along with physiological decline and stem cell senescence. Yet, the direct involvement of circadian mechanisms in nicotine-induced injury to the testes, especially the senescence of spermatogonia stem cells (SSCs), is not well comprehended.
