In a groundbreaking study, researchers at British American Tobacco’s Southampton lab are investigating the genetic and environmental factors influencing smoking-related diseases by studying twins—one smoker and one non-smoker. This research could pave the way for the development of safer cigarettes, potentially reducing the health risks associated with smoking.
Scientists have long been fascinated by the genetic and environmental variables that contribute to smoking habits and their effects. By comparing the health of monozygotic (identical) twins, where one smokes and the other does not, researchers can isolate environmental factors such as tobacco exposure. This method effectively eliminates genetic differences as a variable, providing clearer insights into how smoking affects the body.
The study identified ten biomarkers that were more pronounced in the smoking twins, including elevated levels of carbon monoxide, increased heart rate, and markers linked to inflammation and early-stage vascular disorders. These findings are crucial as they help target specific physiological changes caused by smoking, which future "reduced-risk" cigarettes could potentially mitigate.
Despite the innovative approach, the concept of "safer" cigarettes is met with skepticism. Health experts argue that no form of tobacco is safe. Amanda Sandford from Action on Smoking and Health (ASH) emphasizes that modifying cigarette contents might delay smokers from quitting, as they might perceive these new products as less harmful.
The tobacco industry, including giants like British American Tobacco, which employs around 60,000 staff globally, is keen on developing products that could potentially reduce smokers' risk of disease. However, public health advocates are concerned that these efforts could undermine smoking cessation campaigns by implying that smoking can be safe if the right products are used.
As research progresses, the first clinical trials' results are eagerly anticipated. These will provide more concrete data on whether the prototype cigarettes genuinely reduce health risks compared to conventional cigarettes. The ongoing debate between potential harm reduction and the encouragement of smoking cessation continues to shape tobacco research and public health policies.
According to the World Health Organization, tobacco kills more than 8 million people each year. Studies like the twin research at British American Tobacco’s lab are part of broader efforts to reduce this number, either by making safer products or by providing more data to support robust anti-smoking regulations.
The twin study by British American Tobacco represents a significant step in understanding how smoking affects health and opens up new avenues for developing potentially safer tobacco products. However, the balance between innovation in tobacco products and the promotion of quitting smoking remains a contentious issue in public health discourse.
