Smoking and tobacco controls
https://www.highbeam.com/doc/1P2-35232956.html
Ireland has the worst problem with tobacco smuggling of any country in Western Europe. Furthermore, according to the OECD, it has also seen the smallest reduction in smoking prevalence of any Western European country in the last twenty years. These two facts strongly suggest that the Irish model of tobacco control has been a failure. As widely predicted, its high taxes and endless regulations have unleashed serious unintended consequences without meaningfully discouraging the smoking habit.
