Making smoking history: temporal changes in support for a future smoking ban and increasing taxes in the general population of Denmark.

Background: An end date for smoking has been adopted in several countries and is now being discussed by governments all over the world. However, little is known about temporal changes in citizens' support for a future smoking ban.

Aim: To examine temporal changes in support for a future smoking ban and for increasing taxes on tobacco in Denmark, and to explore whether these changes differ across sex, age, educational attainment, smoking status and between smokers with/without intention to quit.

Method: The study was based on two waves of 'The Danish Capital Region Health Survey' conducted in 2013 and 2017. The pooled study sample included 96 521 citizens aged ≥16 years old.

Results: Public support for a future smoking ban increased from 30.6% in 2013 to 50.3% in 2017, whereas support for increasing tobacco taxes remained unchanged at 59%. Support for a future smoking ban increased significantly in almost all subgroups from 2013 to 2017: Support among daily smokers increased by 27% between 2013 and 2017. Support among never smokers was almost 2.63 times higher than among smokers in 2013 and increased further in 2017 (OR: 2013=2.63; 2017=5.13).

Conclusion: This study indicates a readiness to support a future smoking ban and increasing tobacco taxes. Support for a future smoking ban has increased from 2013 to 2017 among both young people and adults. By 2017, about half of the population supported a future smoking ban and increasing tobacco taxes. Findings may help inform policy-making related to endgame strategies.
