
1 in 3 cancer deaths are caused by smoking


MD assisted quit rates at one yr are 10-30%
“Not enough time”
“Minimal interventions
lasting less than 3
minutes increase
overall tobacco
abstinence rates.”
The PHS Guideline
(Strength of Evidence = A)
“I can’t help patients stop.”

Effective interventions
exist:
 Pharmacotherapy
 Brief
counseling
 System
changes
Guideline available at www.ahrq.gov
Tobacco use results in a
true drug dependence

Tobacco dependence exhibits classic
characteristics of drug dependence

Nicotine:
 Nicotine is as addictive as heroin
 Causes physical dependence
characterized by withdrawal symptoms
upon cessation
 Smokers use tobacco to regulate their
moods and emotions
Tobacco dependence is a
chronic disease

Tobacco dependence requires ongoing rather
than acute care

Relapse is a component of the chronic nature
of the nicotine dependence — not an
indication of personal failure by the patient or
the clinician
The 5 A’s
For Patients Willing To Quit
ASK about tobacco use.
 ADVISE to quit.
 ASSESS willingness to
make a quit attempt.
 ASSIST in quit attempt.
 ARRANGE for follow-up.

Smoking as a vital sign (SVS) ASK:
Ask every patient at every visit
“Do you currently use any tobacco products?”

Even brief advice to quit results in greater
quit rates
“As your health care
provider, I must tell you that
the most important thing you
can do to improve your
health is to stop smoking.”
