Marlboro Light is a brand of cigarette manufactured by Philip Morris USA, a subsidiary of Altria Group, Inc. Marlboro Lights are also known as Marlboro Gold or Marlboro Milds in some countries. The cigarettes are marketed as a “light” or “mild” version of Marlboro’s traditional full-flavored cigarettes. However, it is important to note that the terms “light” and “mild” do not necessarily mean that the cigarettes are less harmful than regular cigarettes. All cigarettes, including light cigarettes, are harmful and can cause serious health problems, including lung cancer, heart disease, and respiratory problems.
