Smoking prevalence following the announcement of tobacco tax increases in England between 2007 and 2019: an interrupted time-series analysis.

The announcements of tax increases for cigarettes in England between 2010 and 2019 were inconsistently associated with temporary reductions in smoking prevalence, per-capita self-reported cigarette consumption and improved quit success. Paradoxically, reductions in the cost for roll-your-own cigarettes were also found. The results were not robust in all sensitivity analyses.
