Conventional wisdom holds the universal truth that littered cigarette butts are unsightly; an undesirable side effect of a habit which most smokers wish they could drop. But while many smokers may not be successful in dropping their habit, they are far too successful at dropping their cigarette butts in the streets. According to Litter Free Planet, a nonprofit anti-litter organization, 4.5 trillion cigarette butts are littered worldwide annually, accounting for 75% of the 6 trillion sold. Keep America Beautiful, another anti-litter educational group, reports that cigarette butts account for an estimated 38% of litter in the United States, and states, counties, and municipalities spend a collective $1.3 billion on litter abatement annually. Another $9 billion and $241 million annually is spent by private businesses and educational institutions, respectively. If the cost of cigarette litter abatement is proportional to the percentage of the litter which it comprises, then cigarette butt litter clean-up costs the United States $4 billion per year. And this is just the direct cost. Additional costs are born in forest fires ignited by improper disposal of lit cigarettes, decreased property values in littered neighborhoods, and lost tourism revenues in regions with littered roadsides or in coastal town beaches mistaken for ashtrays.
