Do pictorial health warnings on waterpipe tobacco packs matter? Recall effectiveness among Egyptian waterpipe smokers & non-smokers

Abstract

Despite the global rise in waterpipe tobacco smoking (WTS), the effectiveness of waterpipe tobacco health warnings remain understudied, especially in countries with high WTS rates. Egypt has been employing waterpipe tobacco labelling for a decade, however, their effectiveness is unknown. Our overall aim was to measure the effectiveness of pictorial health warnings (PHWs) on waterpipe tobacco packs (WTPs) through participant memory recall and to investigate whether they induced behavioural responses in waterpipe smokers and deterred uptake of WTS in non-smokers, examining the differentials of effectiveness among socio-demographic subgroups.
