2004 REPORT of the SURGEON GENERAL
Smoking harms nearly every organ of the body, causing many diseases and reducing the health of smokers in general.
Quitting smoking has immediate as well as long-term benefits, reducing risks for diseases caused by smoking and improving health in general.
Smoking cigarettes with lower machine-measured yields of tar and nicotine provides no clear benefit to health.
Numerous diseases are caused by smoking.U.S. Department of Health and Human Services. The Health Consequences of Smoking: A Report of the Surgeon General, 2004.
FOUR MAJOR CONCLUSIONS
HEALTH CONSEQUENCES of SMOKING
Cancers Lung Laryngeal, pharyngeal, oral
cavity, esophagus Pancreatic Bladder and kidney Cervical and endometrial Gastric Acute myeloid leukemia
Reduce fertility in women, poor pregnancy outcomes, low birth weight babies, sudden infant death syndrome
Cardiovascular diseases Subclinical atherosclerosis Coronary heart disease Stroke Abdominal aortic aneurysm
Respiratory diseases Acute respiratory illnesses,
e.g., pneumonia Chronic respiratory
diseases, e.g., COPD
Cataract
Periodontitis
U.S. Department of Health and Human Services. The Health Consequences of Smoking: A Report of the Surgeon General, 2004.
CAUSALLY ASSOCIATED HEALTH RISKS of SECOND-HAND SMOKE
Developmental effects Fetal growth retardation, SIDS
Carcinogenic effects Lung cancer, nasal sinus cancer
Cardiovascular effects Heart disease mortality, acute and chronic CHD morbidity
Respiratory effects Children: acute lower respiratory tract infections,
asthma induction and exacerbation, chronic respiratory symptoms, middle ear infections
Adults: eye and nasal irritation
National Cancer Institute. Health Effects of Exposure to Environmental Tobacco Smoke: The Report of the California Environmental Protection
Agency, 1999.
EVEN A LITTLE SECOND-
HAND SMOKE IS
DANGEROUS
SMOKE-FREE WORKPLACE LAWS
Smoke-free offices, restaurants, and bars:Delaware, California, Connecticut, Maine, Massachusetts, New York, Rhode Island Smoke-free offices and restaurants: Florida, Idaho, Vermont, UtahSmoke-free offices: Maryland
Exposure to second-hand smoke increases the risk of myocardial
infarction.

QUITTING: HEALTH BENEFITS
Lung cilia regain normal function
Ability to clear lungs of mucus increases
Coughing, fatigue, shortness of breath decrease
Excess risk of CHD decreases to half that of a
continuing smokerRisk of stroke is reduced to that of people who have never smoked
Lung cancer death rate drops to half that of a
continuing smoker
Risk of cancer of mouth, throat, esophagus,
bladder, kidney, pancreas decrease
Risk of CHD is similar to that of people who have never smoked

CLINICAL PRACTICE GUIDELINE for TREATING TOBACCO USE and DEPENDENCE
The 5 A’s (cont’d)
Ask about tobacco use “Do you ever smoke or use any type of tobacco?”
“I take time to ask all of my patients about tobacco use—because it’s important.”
ASK
The 5 A’s (cont’d)
tobacco users to quit (clear, strong, personalized, sensitive) “It’s important that you quit as soon as possible,
and I can help you.”
“I realize that quitting is difficult. It is the most important thing you can do to protect your health now and in the future. I have training to help my patients quit, and when you are ready, I will work with you to design a specialized treatment plan.”

PHARMACOTHERAPY
“All patients attempting to quit should be encouraged to use effective pharmacotherapies for cessation except in the
presence of special circumstances.”

DIRECTIONS for USE
Use gum according to recommended dosing schedule (to decrease cravings & withdrawal symptoms)
Chew each piece very slowly several times
Stop chewing at first sign of peppery, minty, or citrus taste or of slight tingling in mouth (~15 chews, but varies)
“Park” gum between cheek & gum (to allow absorption of nicotine across buccal mucosa)
NICOTINE GUM:
DIRECTIONS for USE (cont’d)
Resume slow chewing when taste or tingle fades
When taste or tingle returns, stop and park gum in different place in mouth
Repeat chew/park steps until most of the nicotine is gone (taste or tingle does not return; generally 30 minutes)

CHEWING TECHNIQUE SUMMARY
Park

NICOTINE GUM:GRADUAL REDUCTION of DOSE
Recommended strategies for discontinuing use of nicotine gum:
Chew gum for 10–15 minutes instead of 30 minutes
Chew each piece for more than 30 minutes but reduce the number of pieces used daily
Substitute ordinary chewing gum for nicotine gum
NICOTINE GUM: ADDITIONAL PATIENT EDUCATION
To improve chances of quitting, use at least nine pieces of gum daily

The RESPONSIBILITY of HEALTH PROFESSIONALS
It is inconsistent
to provide health care and
—at the same time—
remain silent (or inactive)
about a major health risk.
TOBACCO CESSATION is an important component of
THERAPY.
DR. GRO HARLEM BRUNTLAND,
DIRECTOR-GENERAL of the WHO:
“If we do not act decisively, a hundred years from now our grandchildren and their children will look back and seriously question how people claiming to be committed to public health and social justice allowed the tobacco epidemic to unfold unchecked.”
