Data on smoking and e-cigarette use for Great Britain for those aged 16 years and
over come from the Opinions and Lifestyle Survey (OPN). In March 2020, the OPN was
transformed from a monthly to weekly omnibus survey to understand how the coronavirus
(COVID-19) pandemic was affecting life in Great Britain. As a result, the number of
questions relating to smoking and vaping habits was greatly reduced. For more information
on the OPN survey methodology, see our Opinions and Lifestyle Survey QMI.
The analysis reported in this bulletin used survey weights to make estimates
representative of the population. Survey weights take into account observed patterns of
non-response and attrition, as well as the distribution of population characteristics,
like sex and age, where someone lives, and socio-economic characteristics.
