==Flavored cigarettes==
[[Cigarette]]s may be flavored to mask the taste or odor of the tobacco smoke, enhance the tobacco flavor, or decrease the social stigma associated with smoking.<ref name=Carpenter /> Flavors are generally added to the tobacco or rolling paper, although some cigarette brands have unconventional flavor delivery mechanisms such as inserting flavored pellets or rods into the cigarette filter.<ref name=Carpenter /> Cigarette flavors include anise, clove, cinnamon, spearmint, wintergreen, citrus, fruit, and alcohol (especially [[rum]] and [[cocktails]]).<ref name=Carpenter /><ref name=Simpson>{{Cite journal| issn = 1468-3318| volume = 13| issue = 2| pages = 105–106| last1 = Simpson| first1 = David| title = USA/Brazil: the flavour of things to come| journal = Tobacco Control| date = 2004-06-01| url= | pmid = 15175519| pmc = 1747868}}</ref> Flavors may be added to the tobacco, cigarette paper, filter, or even to the foil wrapper.{{r|WHO|pp=34}} Some tobacco companies have developed unconventional flavor delivery systems, including polymer pellet technology, using a flavored filter pellet (polyethylene bead), flavor micro-encapsulation in the paper or packaging technology, flavor fibers inserted into the filter, and flavored tips.{{r|WHO|pp=34}} Flavorings are typically added at the end of the cigarette manufacturing process.{{r|WHO|pp=25}} Flavored cigarettes are heavily preferred by youth, with a 2008 study finding that adolescents and young adults ages 17–25 use flavored cigarettes at about twice the rate of adults age 25 and older, with 17- to 18-year-olds being the heaviest users of flavored cigarettes, using them three times as much as adults.<ref>{{cite journal |last1=Klein |first1=Sarah M. |last2=Giovino |first2=Gary A. |last3=Barker |first3=Dianne C. |last4=Tworek |first4=Cindy |last5=Cummings |first5=K.
