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)

Usage of E-Cigarettes In American Teens Have Reached ‘Epidemic Proportions’: FDA

Gottlieb slammed the e-cigarette makers for approaching the problem of underage use as "a public relations challenge.''

American teens’ use of e-cigarettes has hit “epidemic proportions,” the U.S. Food and Drug Administration said in a statement released Wednesday.

In what it called the “largest coordinated enforcement effort in FDA history,” the agency issued written warnings and fines to 1,300 retailers for their role in selling the devices to children.

According to the data cited by the FDA, last year more than 2 million middle school and high school students used the devices, which deliver nicotine in an inhalable form.

In a speech at FDA headquarters, Commissioner Scott Gottlieb said, “The disturbing and accelerating trajectory of use we’re seeing in youth and the resulting path to addiction must end.”

Until now, the FDA had eyed e-cigarettes as a powerful tool to help adults break their habit of using conventional tobacco products. But research has found little evidence of such products’ effectiveness.

Gottlieb admitted that the agency had neglected to take into account how attractive the flavored products would be to youths.

The commissioner said the FDA would continue to study e-cigarettes as a less harmful alternative for adult smokers, but “that work can’t come at the expense of kids.”

The FDA said it was giving the makers of Juul, Vuse, MarkTen XL, Blu and Logic, the five top-selling brands, 60 days to present the agency with a viable plan to prevent vaping among children. If they fail, it could order the products off the market.

The five brands account for more than 97 percent of U.S. sales, according to the FDA.

Critics have long argued that the manufacturers of e-cigarettes are deliberately targeting children by offering their products in sugary flavors.
