LONDON: Archaeologists have discovered that smoking leaves permanent traces in the bones of individuals, persisting not only throughout their lives but also for centuries after their deaths. This revelation comes from a study conducted by researchers at the University of Leicester, who examined human remains buried in Britain between the 12th and 19th centuries. The findings highlight the significant impact of tobacco on bones and its association with bone-related conditions, such as an increased risk of fractures.

According to Azerbaijan State News Agency, the study underscores how the introduction of tobacco to Western Europe around 500 years ago led to noticeable changes in human skeletal structure. Traditionally, archaeologists relied on dental evidence to determine if a skeleton belonged to a smoker, searching for stains or wear caused by pipe use. However, this method often proved ineffective when teeth were missing or did not survive over time.

The research team from the University of Leicester analy
zed 323 cortical bones, the dense outer layer providing strength, from individuals known to have used tobacco and those with unknown smoking histories. Employing mass spectroscopy, they identified 45 distinct molecular features differentiating the bones of smokers from those of non-smokers. The study, published in Science Advances, states: “Tobacco consumption leaves a metabolic record in human bone distinctive enough to identify its use in individuals of unknown tobacco consumption.”

Dr. Sarah Inskip, a co-author of the study, noted, “Our research shows significant differences in the molecular features of bones from past tobacco users and non-users. This finding indicates that tobacco use impacts the structure of our skeletons. Our ongoing research aims to understand how these differences emerge, which may have implications for understanding why tobacco use is a risk factor for certain musculoskeletal and dental disorders.”

While the adverse effects of smoking on soft tissues and organs, such as increased
risks of lung, bladder, and throat cancers, as well as stroke and coronary artery disease, are well-documented, the impact on bones has received less attention. Smoking has been linked to bone-related conditions, including low bone density, an increased risk of fractures, and periodontitis.

This research not only provides insight into the historical prevalence of smoking but also emphasizes the extensive and enduring impact of tobacco on human health. It offers valuable insights into the skeletal consequences of this widespread habit, contributing significantly to the understanding of tobacco’s long-term effects.
