It is vitally important that we show people that the use of tobacco cigarettes has harmful consequences throughout the body, including large muscle groups needed for daily living, and develop strategies to stop the damage triggered by the detrimental components of cigarette smoke

If you believe that smoking affects only the lungs, then you may be wrong as a new study showed that components in cigarette smoke may directly damage the muscles in your leg as well.

According to the researchers, smoking could directly damage the muscles by reducing the number of blood vessels in leg muscles, which in turn reduce the amount of oxygen and nutrients the muscles received.

“It is vitally important that we show people that the use of tobacco cigarettes has harmful consequences throughout the body, including large muscle groups needed for daily living, and develop strategies to stop the damage triggered by the detrimental components of cigarette smoke,” said lead author Ellen Breen from the University of California-San Diego, US.

Under a mouse model, a team of researchers from California along with Universidade Federal do Rio de Janeiro in Brazil and Kochi University in Japan, exposed the mice to smoke from tobacco cigarettes for eight weeks, either by inhalation or by injecting them with a solution bubbled with smoke.

The results, published in The Journal of Physiology, also showed that the reduced level of oxygen and nutrients due to reduced blood vessels may impact the metabolism and activity levels.

Both these are risk factors for many chronic diseases including chronic obstructive pulmonary disease (COPD) and diabetes.
The study, however, could not identify the chemical responsible out of the 4,000 chemicals in a cigarette smoke that caused the muscle damage.

Researchers said that further study is needed to identify them, along with understanding the process by which they reduce the number of blood vessels. (IANS)

Quit Smoking Else Develop Depression Or Schizophrenia

Study says that smoking cigarettes can increase the risk of developing depression

If you are a regular smoker, quit now as researchers have found that tobacco smoking may increase your risk of developing depression and schizophrenia.

“Individuals with mental illness are often overlooked in our efforts to reduce smoking prevalence, leading to health inequalities,” said study lead author Robyn Wootton from the University of Bristol.

“Our work shows that we should be making every effort to prevent smoking initiation and encourage smoking cessation because of the consequences to mental health as well as physical health,” Wootton added.

For the study, published in the journal Psychological Medicine, the research team used UK Biobank data from 462,690 individuals of European ancestry, comprising 8 per cent current smokers and 22 per cent former smokers.

The team applied an analytic approach called Mendelian randomisation, which uses genetic variants associated with an exposure (e.g. smoking) to support stronger conclusions about cause-and-effect relationships.

“The increasing availability of genetic data in large studies, together with the identification of genetic variants associated with a range of behaviours and health outcomes, is transforming our ability to use techniques such as Mendelian randomisation to understand causal pathways,” said study senior author Marcus Munafò.

“What this shows is that genetic studies can tell us as much about environmental influences – in this case the effects of smoking on mental health – as about underlying biology,” Munafo added.

The research also suggests that smoking can have adverse effects on mental health.This new evidence adds further weight to support the implementation of smoke-free policies.

Not only is there evidence that smoking can be detrimental to mental health, but much of the excess mortality associated with depression is due to smoking, the study added. (IANS)
