The soothing effect of menthol may lead people to become quickly addicted to cigarettes because it reduces the respiratory response to irritants present in smoke. The discovery by researchers at Yale University in the United States and has potential application for young people who have a preference for menthol cigarettes.

The agent of refreshing peppermint is added to almost all cigarettes sold in the marketplace today, in varying degrees. But until now, little was known about the pharmacological effects of menthol on smoking and its connection with addiction and related diseases.

The researchers found that rats who inhaled menthol immediately abolished the response of airway receptors that promote feelings of irritation to protect the respiratory system. The equivalent of a smoker's cough "in mice was almost completely blocked when they inhaled menthol and tobacco together.

By removing the irritating sensation, menthol can make smoke inhalation easier to be tolerated and, therefore, promote nicotine addiction and related diseases. This is a particular risk to young people who are just starting to smoke. Studies indicate that most smoke menthol cigarettes. So they are being exposed to higher levels of nicotine and other toxic substances at an early age, which can quickly lead to dependence and, ultimately, the development of smoking-related diseases, "noted teacher and author of the study Sven-Eric Jordt.

In 2009, Congress passed the Law on the Family Smoking Prevention and Tobacco Control, which banned the use of flavored additives such as cloves, cinnamon candies, chocolate or fruit flavors. However, menthol has been exempted from the ban. The regulatory agency of the U.S. Food and Drug (FDA Food and Drug Administration) is currently evaluating scientific data on the substance refreshing, however, and may decide to ban it if it is considered harmful.
