Our story

We are BAT Science

Millions of adult smokers around the world are switching to alternative products.

Here at BAT, we have used our 117+ years of expertise in tobacco to develop a range of vapour, tobacco heating and modern oral products which we believe could be less risky than smoking cigarettes.

Our story

We are proud of our world-leading scientific research and we are committed to providing our consumers with less risky tobacco and nicotine choices.

Find out how we are transforming both our company and industry through sound science and constant innovation. Explore our potentially reduced-risk products and the science behind them.


Our focus

Our potentially reduced-risk products are rigorously tested by our scientists to make sure they are as safe and as satisfying as possible. Our five-step risk assessment framework analyses how people use the products, what is in the emissions, how the emissions impact human cells in the lab, how the products affect the body in clinical trials, and what impact the products could have on the population.

Safe and satisfying products

Open communication

We take an open and transparent approach to our work, and all our scientific papers are available for everyone to read and learn from. You can take a look at our library. Our scientists proudly present their research at conferences all over the world and further their learning by collaborating with other experts. Find out more about our science engagement.


Science powering innovation

We are proud of our diverse community of experts whose scientific research is powering our technology and product innovation. We believe an inspired culture of curious, agile and forward-thinking professionals will always be our most competitive differentiation. We acquired Reynolds American Inc. in July 2017 and this brought two strong research & development organisations together, both with a strategic goal of transforming tobacco. RAI’s scientific papers and conference materials, published from 2018 onwards, can be found in our library.




Technology and innovation

Innovation is key to our pipeline of potentially reduced-risk products. Our new-to-world technology, the puretech distiller plate, featured in the Vype iSwitch, was the result of an innovative partnership with an Austrian inventor. Find out more about our collaborations with inventors. Our technology scouting unit helps us predict a world that doesn’t exist yet and stay well ahead of the curve. We have become experts in consumer electronics and other new technologies, and our success in this area has been accelerated by recruiting brilliant people from the tech world.


Transforming Tobacco

By working with regulators, politicians, industry peers, academics and the media, we believe we can help transform tobacco and give consumers accurate information to help them make informed choices.

Less toxicants

ePen 3 has 95% less toxicants than cigarettes*

*Comparison to 1R6F ref cigarette and vapour from Vype ePen 3, ref to 9 harmful components WHO recommends to reduce in cigarette smoke. This quality does not necessarily mean this product is less harmful than tobacco products.
