Sweden is the forerunner as country with the lowest number of smokers across Europe and probably even the world with only 5% of the population 16 years and older. The success of these public health policies is due to banning smoking not only form pubs and restaurants, but also outside in the surroundings of public spaces like schools, playgrounds, train stations and sports facilities. These policies work quite well and the effects of discouraging smoking in public is reduced to a minimum rather than the normal encounter.
Health of the other persons and children passing through these areas is not the only goal. A new estimate of lost days or years due to smoking based on a study from England shows that “each cigarette smoked reduces the smoker’s life by about 20 minutes (17 for men, 22 for women, LINK to study). Of course, there is a huge variance and other work and life conditions that play an important role as well, but the broad average estimate is a nice way of talking about statistics. The basis of the estimate is for those who stop smoking and not those reducing their tobacco intake by some percentage or replacement product.
In the Belgian football stadium (image below 2024) in Brussels the No tobacco sign is well placed to make parents of children and youth understand the challenge ahead. Good resolutions are assisted by gentle regular reminders as well.
