Tobacco use is the leading cause of preventable death in
the US: over 400,000 deaths each year
Morbidity and mortality caused by carbon monoxide
(CO) and carcinogens (e.g. tobacco-specific
nitrosamines)
Dependence caused by nicotine: reinforcing effects such
as euphoria, increased arousal, reduced stress, and
appetite suppression
Use of tobacco often leads to an aversive withdrawal
syndrome during periods of tobacco abstinence; this
can maintain tobacco use and thus, exposure to harmful
smoke constituents


Currently, about 21% of US adults smoke
cigarettes
Current use of cigarettes among youth:
 5.2% of middle school students
 17.2% of high school students


Rates higher if you include any tobacco
product
Most adult smokers (80%) began smoking
before age 18

Statewide: 16.4% of the adult population are
current cigarette smokers (BRFSS)

11-13% of youth aged 12-17 smoked 1 cigarette
in the past 30 days (NSDUH/VYTS)

Use of any tobacco in past 30 days: (cigarettes, cigars,
smokeless tobacco, pipes, bidis, hookahs, Black and Milds, and
SNUS)
 14% of middle-school students
 34% of high school students

Cigarettes
 First developed 1800s
 US: 1930s – 1970s, start to see changes to
cigarettes
 Filters and “full flavor” vs “light” vs “ultra light”
 Start to see health claims, even after 1964
Surgeon General’s report on the dangers of
smoking
Source: Dr. Ken Warner.
 “Patients who are unable to stop cigarette smoking
should be assisted to reduce their smoke exposure
by smoking low-tar and low nicotine cigarettes . . .”
(Harrison’s Internal Medicine 9th Ed., 1980, p. 941).
 Smokers believe “light” and “ultra light” cigarettes
decrease health risks of smoking (Kozlowski,
Goldberg, et al., 1998; Giovino et al., 1996).
 Smokers switch to low yield cigarettes instead of
quitting (Giovino et al., 1996).
 Changes increased sales without harm reduction
 “The weight of the evidence indicates that lower-tar
and nicotine yield cigarettes have not reduced the
risk of disease proportional to their FTC yields”
(IOM, 2001).
 Past modifications did not alter exposure: changing
puff topography, covering vent holes
 New FDA regulation will eliminate use of “light” etc.
 Newer cigarettes: Eclipse, Advance, Omni
 Bold claims of reduced carcinogens

Cigars
 5.4% of US adults use (>1 in past 30 days)
 3.9% of middle school students
 10.8% of HS students

Kreteks (clove cigarettes) and Bidis

Pipes

Waterpipe, or hookah
 CO exposure is much higher than
cigarettes (Eissenberg et al., 2011)

Overall tobacco use has been going down
(although for cigarettes, is currently stalled)

Use of other products may be increasing

Hard to determine long-term impact of new
products (need to wait say, 20-30 years and
see what happens)





~70% of smokers say they want to quit
45% make quit attempts
Relapse rates are high
Nicotine produces dependence: very difficult
to quit
Nicotine is as addictive as heroin or cocaine

Medications to quit can increase likelihood of
success
 Nicotine replacement therapy (nicotine patch,
gum, inhaler, lozenge, nasal spray)
 Non-nicotine medications: buproprion
(Zyban/Wellbutrin), varenicline (Chantix)

Current study: smoking cessation among
those in recovery from addiction to
alcohol/drugs
80-90% of individuals addicted to other
substances smoke
Tobacco use generally not addressed during
formal treatment
Currently testing brief computerized
motivational feedback in this population to
determine effectiveness

Effective prevention programs are based on
reducing risk factors and/or enhancing protective
factors

Related to age, gender, race, and environment
 A need for preventive interventions tailored to specific
populations and settings

Most risk and protective factors related to a broad
array of youth problems, but some are unique
 Additive effect—goal is to affect the balance of risk and
protective factors

Target Population: Youth 10 to 14 years old (also available for
younger children)
Seven sessions
Parents and youth meet separately for first hour and then
together for second hour
Parent sessions
 Skill-building focused on establishing rules, limits, and consequences
while expressing love; communication with youth; handling stress;
using community resources
 Uses videos demonstrating parenting skills, with role playing,
discussion and skill building activities

Youth sessions
 Youth skill-building focuses on following rules, peer pressure
resistance, handling stress, and problem-solving
 Group discussions, group skill practice, and social bonding activities

Family sessions
 Games and projects to increase family bonding, build positive
communication skills, plan family activities, and facilitate learning to
solve problems together

Systematic review by Brinn et al., 2010 (Cochrane
Collaboration)
 There is some evidence that mass media can prevent the
uptake of smoking in young people, however the evidence is
not strong and contains a number of methodological flaws.
 Effective media campaigns:
▪
▪
▪
▪
Based on good market research
Identify and tailor message to specific groups (market segmentation)
Last longer and more intensive
Use multiple media (TV, radio, newspapers)

Primarily focus preventing illegal sales to minors
 Retailer education
 Active enforcement

Systematic review by Stead, 2008 (Cochrane
Collaboration)
 Active enforcement more effective in reducing sales to
minors
 Little evidence of impact on perceived availability of
tobacco products or on prevalence of youth smoking (only
three controlled trials)


Enacted in 1992
Required States to enact laws prohibiting the
sale or distribution of tobacco products to
those under 18 years old
 Required unannounced inspections of retail
outlets and reporting of results
 “False buys”
 Established targets for “violation rates”
 Failure to meet targets could result in loss of
funds—up to 40% of SAPT Block Grant

Create a financial disincentive to use tobacco

Based on known relationship between price
and sales
 Elasticity of demand (Ed ) is percentage change in
sales as a result of percentage change in price
 Ed = -1.5 (10% increase in prices results in 15%
reduction in sales



Relationship between price and sales
(demand) complicated by role of addiction
Adults Ed = -.40 (NCI, 1993)
Less research on youth
 Illegal product for youth

Generally believed that youth are more price
sensitive
 Less disposable income
 Less addicted

Youth Ed = -.9 to -1.5

“Policies that affect the price of tobacco
products are the single most effective means
of decreasing tobacco use, especially among
youth and young adults.” (CDC, 1998)

decreasing wholesale price

Opportunity for Student Participation
The Virginia Youth Tobacco Projects (VYTP)
Research Coalition was established to
advance the prevention and treatment of
youth tobacco use and nicotine dependence
through a coordinated, multi-university
program of basic and applied research.





Build a statewide program of research on the causes
and prevention of youth tobacco use
Create active multi-university collaborations in
carrying out the VYTP research program
