Tobacco products can use a range of design features to meet consumer expectations and regulatory requirements. No cigarette is safe; this applies to all variations of the conventional cigarette type, including “low tar” and “slim” cigarettes.

Whilst it is possible to reduce certain constituents in tobacco smoke, many of the currently available reduction methods rely on product features, such as filter ventilation.

Smokers should not assume that any feature reduces the health risk of smoking a tobacco product.



Filtration for tobacco products became popular in the 1950s. Today, there are many different types of filter using different raw materials, filter shapes, and contents such as activated charcoal.

Although there are filter types that have been shown to reduce some components of tobacco smoke, no cigarette should be considered safe.



Filter ventilation is the primary cigarette design tool available to reduce smoke emissions in line with regulatory requirements around the world, for example, nicotine and carbon monoxide. For some smoke components, lower levels can only be achieved through filter ventilation.

Filter ventilation is usually achieved through small cuts in the material around the filter, which allows air to pass through when a smoker inhales.

Although it is possible to reduce certain constituents in cigarette smoke both by this approach and other design features, smoke is a complex mixture and no cigarette, irrespective of design, should be considered safe. This applies equally to different formats such as “slim” cigarettes. 

No laboratory smoking regime can accurately replicate how a consumer smokes a cigarette, so we have conducted research to model how smokers use our products; these studies can be found here.
