<br />smokers; 18.6% of the population reported lifetime use of greater than 100 cigarettes and some level of current use.
<br />a special susceptibility to even
<br />experimental tobacco use.' Low
<br />minimum sales age laws exploit
<br />that susceptibility to addict youths
<br />to cigarettes for life, with relatively
<br />few cigarettes. Meanwhile, raising
<br />the sales age would appear likely
<br />to have a significant effect on
<br />current tobacco use rates among
<br />youths, decreasing the chances of
<br />a person ever becoming tobacco
<br />dependent. By some estimates,
<br />raising the tobacco sales age to 21
<br />years would reduce tobacco use
<br />prevalence by 55% for 15- to
<br />17 -year-old adolescents within
<br />7 years. 16
<br />In 2005, Needham, Massachu-
<br />setts, was the first town in the
<br />country to implement the law to
<br />raise the tobacco sales age to 21
<br />years. Following the implementa-
<br />tion of the law, the Youth Risk
<br />Behavior Surveillance System
<br />and Metro West Health Founda-
<br />tions' Adolescent Health survey
<br />data showed a 47% reduction in
<br />Needham high-school smoking
<br />rate in the 4 years (2006-2010)
<br />after the legislation was imple-
<br />mented 17 Of note, no tobacco re-
<br />tailers have gone out of business in
<br />Needham since implementation.
<br />tobacco sales, we have accounted
<br />for any tobacco that is smoked and
<br />self-reported as a cigarette, the
<br />form that has the highest disease
<br />burden. According to the Centers
<br />for Disease Control and Preven-
<br />tion's Morbidity and Mortality
<br />Weekly Report, about 90% of all
<br />combustible tobacco consumption
<br />is cigarettes among adult smokers.'a
<br />In addition, 2012 National Youth
<br />Tobacco Survey data indicate that
<br />the majority of tobacco consump-
<br />tion remains cigarettes, and high-
<br />school students in the young adult
<br />age range (> 17 years) are 3 times
<br />more likely to smoke cigarettes
<br />daily than use any other combina-
<br />tion of cigars, bidis, and cigarillos
<br />on a daily basis.
<br />Adult versus youth smokeless
<br />tobacco use rates and amount
<br />consumed are much harder to
<br />quantify and we intentionally ex-
<br />cluded these to avoid reporting
<br />bias. In addition, the US retail
<br />cigarette market is more than 30
<br />times greater than the smokeless
<br />tobacco market, making any adult
<br />versus youth consumption dis-
<br />crepancy unlikely to change our
<br />overall estimate of the tobacco
<br />sales impact.19

<br />21 years, yet most lifetime tobacco
<br />users start smoking before the
<br />age of 21 years. Early tobacco
<br />initiation during young adulthood
<br />comes with a high probability of
<br />addiction, progression to daily
<br />smoking, and heavier tobacco use
<br />in adulthood, and has long-term
<br />harmful health consequences.
<br />Action on this critical issue of raising
<br />the minimum tobacco sales age to
<br />21 years across the United States
<br />has excellent public health and
<br />ethical rationales, and costs almost
<br />nothing to implement through
<br />existing regulatory frameworks.
