The development of e-cigarettes has renewed interest in products that reduce the harm from tobacco use. This column argues that recent research appearing to demonstrate a link between e-cigarettes and respiratory disease does not tell the whole story. Adopting a more flexible empirical specification that takes into account whether people are never smokers, former smokers or current smokers, the authors find no evidence that current or former e-cigarette use is associated with respiratory disease among respondents who had never smoked combustible tobacco. Moreover, while dual users are more likely to develop respiratory disease than non-smokers, there do not appear to be significant differences between dual users and smokers.

Traffic congestion is a major problem for urban centres. Among various negative externalities, traffic creates substantial pollution which can impact the health of residents. This column explores how the implementation of a congestion pricing zone affected the health of children in Stockholm. The programme saw short-term reductions in common traffic pollutants and an accompanying decrease in children’s hospital visits for acute asthma. This decrease grew larger the longer the tax was in place.
