Cigarette

A cigarette (French: "small cigar", from cigare + -ette) is a small roll of finely cut tobacco leaves wrapped in a cylinder of thin paper for smoking. Its smoke is inhaled from the other end, which is held in or to the mouth and in some cases a cigarette holder may be used as well. Most modern manufactured cigarettes are filtered and include reconstituted tobacco and other additives. Cigars are typically composed entirely of whole-leaf tobacco.

 Until 1920, cigarettes were widely known as sedative that can release smokers from stress. Many doctors in that era supported the opinion. Seventy years after, scientists were able to discover the negative effect of cigarettes.
