A<unk>  and a pack of Marlboro Silver Pack (previously called Ultra Lights until the "light" name was banned as deceitful)<unk> s (labeled in certain jurisdictions as Light or Mild<unk> s) are considered to have a milder flavor than regular<unk> s. These<unk>  brands may be listed as having lower levels of tar ("low-tar"), nicotine, or other chemicals as "inhaled" by a "smoking machine". However, the scientific evidence is that switching from regular to light or low-tar<unk> s does not reduce the health risks of smoking or lower the smoker's exposure to the nicotine, tar, and carcinogens present in<unk>  smoke. The filter design, which may include perforated holes, is one of the main differences between light and regular<unk> s. When attached to a smoking machine, the small holes in the sides of the filter dilute the tobacco smoke with clean air. In ultra-light<unk> s, the filter's perforations are even larger, and on the smoking machine, they produce an even smaller smoke-to-air ratio. However, smokers react to the reduced resistance by inhaling more deeply, and tend to cover the holes with their fingers and mouth. None of these ventilation techniques reduce harm to smokers, and some may increase it; they are designed to give better readings in a smoking-machine test while minimally reducing what human smokers inhale. Belief among the general public that "light"<unk> s are less harmful and less addictive is pervasive and problematic to public health efforts. Usage of descriptors such as "light" or "mild" has thus been banned in the European Union, Australia, Malaysia, Philippines, the United States, and other countries. Tobacco manufacturers now use color-coding to allow consumers to differentiate between regular and light brands, using lighter colors and silver for "light"<unk> s. Plain tobacco packaging does not appear to be helpful in reducing marketing influence.
