Costs

• Direct and indirect medical costs from one year of smoking in the US– $157 billion (75 direct, 82 indirect)

• Immunize the entire 3rd world– $2 billion

“The Big Lie”

In the advertisement:

• Peace• Freshness• Good smells• Independence

In real life:

• Coughing• Stale taste, smoke• Bad smells• Dependence

(addiction)

Worldwide toll of smoking• Kills five million people annually worldwide• Will be over 10 million annually by 2050 (Some

countries with 10 million or fewer people: Hungary, Sweden, Belgium, Switzerland, Senegal, Portugal, Greece, Bolivia)

• Half of deaths in middle age (workforce needed for economic development)

• Half of deaths in rich nations, half in developing nations

• Apparent causes of death different (India TB, China COPD)

2. How can it be that bad?

Why Add?

• Enhance flavor• Change burn rates• Change tar/nicotine ratings• Increase delivery of nicotine

What happens when you burn?

Over 4000 chemicals, including …

Selected Chemicals Released When Cigarettes Are Burned

• Benzene• Formaldehyde• Urea• Arsenic• Cyanide• Acetone• Pyridine

• Ammonia• Tar• Carbon

Monoxide• DDT• Butane• Cadmium

A is for Addiction

• Nicotine is a carcinogen itself• Binds to adenosine receptors in the brain,

releasing dopamine (rush); has effect within 10 seconds

• Potent withdrawal begins within minutes• Leads to the next cigarette

B is for blood vessels

• Multiple chemicals in cigarettes cause endothelial damage

• Increases predisposition to clotting, plaque buildup, and heart attack

Atherosclerosis

Myocardial Infarction

Stroke =CVA

(cerebro-vascular accident)

Peripheral Vascular Disease

* From Reducing the Health Consequences of Smoking: 25 Years of Progress. Washington, DC, U.S. Department of Health and Human Services, 1989.

D is for Destruction of Lungs (COPD)

E is for Environmental Smoke (Second-Hand Smoke)

Second Hand Smoke

• 38,000 deaths each year (more than homicide and AIDS combined)

• Most pronounced in waiters, bartenders, spouses

• Infants

“Safer” cigarettes …

• No additives• Low tar• Low nicotine• “Smokeless”

Percentsmokers

“As this 14-24 age group matures, they will account for a key share of the total cigarette volume for at least the next 25

years.”

--RJ Reynolds

“Our studies report on youngsters' motivation for starting, their brand

preferences, as well as the starting behavior of children as young as 5

years old.”

-- Brown and Williamson Tobacco Company

US Tobacco, quoted 1994

“Cherry Skoal is for somebody who likes the taste of candy, if you know what I’m saying.”

4. What do we do about it?

Legislation

• Ban on TV advertising 1971• MSA of 1998 (no billboards)• Clean air laws

Public Service Announcements

• Do have an effect• About 50 “just say yes” for each “just say

no”• US PSA budget is about 1/30 of England,

Canada

School Programs

• “Tar Wars” – 4th and 5th grade• “Social influences” programs

– Grade school: effect on body– Middle school: peer pressure, friends, family– High school: self esteem, aspirations

HSPP• Peterson, AV, JNCI 2000• Curriculum for youth, 3rd-10th grades• 47.25 hours total• “Social Influences” approach• How to say no, effects on body, resisting

peer influence, self esteem, etc.• 20 school districts got the program, 20 did

not• 94% follow up, high implementation fidelity

Results of HSPP

• No difference in smoking at 12th grade• No difference in smoking 2 years after

high school• No difference among boys or girls• No difference among people of other

subgroups (such as family risk for smoking)

Is Media Literacy Different?

Major Reasons for Media Literacy

• Fun, creative• Someone to rebel against• Developmentally appropriate• Most effective for the ones most at risk• Empowering, not protectionist
