Area of Science:

  • Public Health
  • Behavioral Science
  • Tobacco Control

Background:

  • Smoking reduction is an alternative for smokers unwilling or unable to quit.
  • It has not been previously implemented in population-based interventions.

Purpose of the Study:

  • To assess the effectiveness of a population-based smoking reduction intervention.
  • To evaluate if smoking reduction increases motivation to quit tobacco.

Main Methods:

  • A randomized population-based intervention study in Copenhagen, Denmark.
  • Included 2,408 daily smokers across all motivational stages.
  • Offered encouragement to reduce tobacco consumption and optional smoking reduction groups.

Main Results:

Related Experiment Videos

  • 23% reported reducing consumption by at least 5g; 8% reported halving it.
  • Halving tobacco consumption was significantly more frequent than in the background population (OR=2.6).
  • Reduction increased motivation to quit, with halving quadrupling the likelihood.

    • Conclusions:

    • The smoking reduction intervention led to self-reported tobacco reduction and increased quit motivation.
    • This approach may serve as a preliminary step to smoking cessation.
    • It offers a potential supplement to existing smoking cessation strategies.
