  • Correction notice This paper has been revised since first published. Authors incorrectly stated that the FDA had banned menthol as a characterising flavour in cigarettes. While on April 29, 2021 the FDA has proposed this ban, the ban has not yet taken effect. This phrase ‘…while the FDA has now banned menthol as a characterising flavour in cigarettes’ has now been revised to read ‘…while the FDA plans to ban menthol as a characterizing flavour in cigarettes, menthol is still allowed in e-cigarettes’.
