Each year since 2009, Revenue, in conjunction with the HSE’s National Tobacco Control Office, has commissioned Ipsos MRBI to conduct independent market research among smokers about the source of their cigarettes. The purpose of this research is to estimate the volume of non-Irish duty paid cigarettes being consumed in Ireland. Since 2013, this cigarette research has been complemented by an additional survey on roll your own tobacco. The surveys were paused in 2020 due to the COVID-19 pandemic and the associated public health restrictions. The surveys resumed in 2021 and this report summarises their findings.
