A new study shows that so-called “light” cigarettes have likely contributed to the rise of adenocarcinomas – one of the two most frequently diagnosed lung cancers. James expert Dr. Peter Shields explains that, although there are fewer smokers now, adenocarcinomas cases have increased in frequency over recent years, and a new study points to light cigarettes as the culprit. It turns out that the tiny filter holes designed to enable manufacturers to market the cigarettes as light may actually have made them even more dangerous. While technically allowing for less tar and nicotine, smokers began inhaling deeper and smoking more – increasing the level of carcinogens inhaled – in order to satisfy addictive cravings.
