Tobacco Dependence Is a Medical Condition, Not a
Lifestyle Choice
What are the effects of nicotine?
Why do people continue to smoke?
Drop in nicotine levels leads to craving and
withdrawal symptoms

Quitting Smoking Unaided Pooled data
3-5
  • Long-term smoking abstinence in those who try to
    quit unaided 35
  • Most relapse within the first 8 days

A Comprehensive Approachto Smoking Cessation
  • Smoking addiction has two main components that
    need to be addressed one related to the
    pharmacological action of inhaled nicotine and
    the other related to behavioural factors1-3
  • Advice and behavioural support increase chances
    of quitting successfully4,5

Most effective methods of smoking cessation
combine pharmacotherapy with advice and
behavioural support2,4

The Three Strategies Proven to Help Smokers Quit
  • Brief advice support from themselves, their
    family and their physician, as well as groups,
    helplines and web-based resources
  • Behavioural therapies quitting skills, such as
    avoiding people, places and situations that
    trigger their urge to smoke
  • Medication

Hughes JR. CA Cancer J Clin 2000 50(3)143-51.

Effect of Physician Advice on Likelihood of
Quitting
Consistent physician advice doubles the
spontaneous rate of quitting.
Law M, Tang JL. Arch Intern Med 1995
155(18)1933-41.
11
Behavioral Therapy
  • Behavior modification simply means having a plan
    to change your routine as it relates to daily
    cigarette usage
  • Avoiding the riskiest situations what to do when
    one would be smoking favorite cigarettes of the
    day substituting activities at these times
    distractions for the brain
  • No evidence as to whether intensive counselling
    is more effective or not in outcomes

12
Overview of various therapies
Combining medication with brief advice or
behavioural therapy increases CA up to six times.

What About Hypnotherapy and Accupuncture
  • not enough evidence to show whether or not
    hypnotherapy can help people trying to quit
    smoking.
  • no consistant evidence that active accupuncture
    or related techniques increased the number of
    people who successfully quit smoking. However
    accupuncture could be better than doing nothing,
    at least in the short term, and not enough
    evidence to dismiss the possibility that it may
    have an effect

15
Relapse Prevention
  • Nicotine addiction is a chronic, relapsing
    condition
  • Previous quit attempts are a good predictor of
    eventual success
  • Relapses should be viewed as learning
    experiences
  • Patients should not be made to feel guilty
  • Try to understand the situation and find a way to
    deal with it (problem solving !)
  • Repeating courses of medication often necessary
