Q: On a box of parliament light 100's cigarettes it'll say charcoal right above where it says recessed filter. What does the charcoal mean?
A: CHARCOAL RECESSED FILTER Some cigarettes today boast the inclusion of a "charcoal filter" in addition to the more common dense, synthetic fiber filters seen in almost all filter cigarettes. Manufacturers claim that charcoal filters, which contain bits of charcoal embedded within the fiber filters, reduce certain toxins in the smoke. But no evidence exists that these cigarettes are significantly less dangerous for the user.
