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

Agency, 1999.

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.

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

PHARMACOTHERAPY

“All patients attempting to quit should be encouraged to use effective pharmacotherapies for cessation except in the

presence of special circumstances.”

Fiore et al. Treating Tobacco Use and Dependence. Clinical Practice Guideline. Rockville, MD: USDHHS, PHS, 2000.

PHARMACOLOGIC METHODS:

FIRST-LINE THERAPIES

Two general classes of FDA-approved drugs for cessation:

1. Nicotine replacement therapy

Nicotine gum, patch, lozenge, nasal spray, inhaler

2. Psychotropics

Sustained-release bupropion

NICOTINE GUM:

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

ADVANTAGES Gum use may

satisfy oral cravings.

Gum use may delay weight gain.

Patients can titrate therapy to manage withdrawal symptoms.

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.”
