Welcome to Research & Development at British American Tobacco, where you will find an overview of our current research and development programmes, research data and recently published papers and posters.
Cigarette smoking is a cause of serious and fatal diseases, so our research and development activities are principally focused on better understanding the mechanisms of harm caused by tobacco use and on developing potentially less harmful products which address this issue. The science of tobacco harm reduction is complex, extremely challenging and spans many scientific disciplines. We have significantly expanded our research capabilities and expenditure over the past few years to reflect the importance we place on work in this area.
We welcome your comments on this website and are pleased to discuss our science or possible collaboration with other scientists working in related areas.
New content launched During the last 12 months we have conducted several independent reviews of the site. We have improved the breadth and depth of the scientific content and included additional pages on smoke exposure, in vitro modelling, human dosimetry and clinical assessment amoung others.

Our smoke exposure research includes both literature based research into toxicants as well as an extensive laboratory based programme investigating the effects of tobacco smoke exposure using in vitro models.

Our work in human dosimetry, therefore, is moving beyond standard machine measurements to study smokers with the aim of obtaining yields from cigarettes through analysis of smoked cigarettes.
