Total bans on smoking in public increase kids’ exposure by encouraging smokers to light up at home, the first study on the direct effect of passive smoking has found.

While bans in public transportation or in schools were found to decrease the exposure of non-smokers, those in recreational public places, such as bars, restaurants or recreational facilities, increased their exposure by displacing smokers to private places where they contaminate non-smokers, and in particular young children. Increasing tax on cigarettes reduces the exposure of young children but has little effect on non-smoking adults, which suggests that smokers cut down at home but not during social activities with other adults.
