Background
Vaping has become prevalent in many countries
In Wales, vapes are currently regulated as consumer products
It is important to track vaping and assess how far they appear to be promoting or detracting from reduction in prevalence of cigarette smoking
Aims
To track vaping over time and assess how far any increase is accompanied by changes in:
- use of other aids to cessation or smoking reduction
- key performance indicators for tobacco control (smoking prevalence, smoking cessation rates, attempts to stop smoking, success of attempts to stop smoking)
To assess prevalence of vaping in people who have never smoked regularly or stopped for more than a year
To estimate changes in the total tobacco and nicotine market
Methods
Monthly household surveys
Each month involves a new representative sample (16 and over) of ~300 respondents.
Due to the pandemic, surveys conducted by telephone (rather than face-to-face) and, until December 2021, among adults aged 18 and over.

Summary I
An estimated 12-18% of the adult population in Wales vape
Use of heated tobacco products is rare
Approximately 1 in 5 long-term ex-smokers (quit >1 year) use vapes, but use among never smokers is relatively rare
Around 30-50% of vapers are dual users (also smoke)
A similar proportion of daily vapers are ‘dual users’ (also smoke)
Summary II
The majority of vapes used contain nicotine
Never smokers are most likely to use e-liquids with 20mg or more of nicotine. A minority of users did not know the strength
Specialist vape shops (including online specialist) are most popular source for purchase among smokers and ex-smokers
Supermarkets are most popular among never smokers
Summary III
Approximately 1 in 3 smokers use vapes
Vapes are the most popular aid used in a smoking quit attempt
Summary IV
Roughly 1 in 4 smokers believe vapes are more harmful than cigarettes and around 1 in 3 believe they are equally harmful
