A survey of more than 3,000 British smokers says they are happy with the vaping industry.
The survey of 2,400 smokers was conducted by Ipsos MORI, which was commissioned by the British Lung Foundation.
Its findings are based on a sample of 2.3 million smokers who use e-cigarettes in Britain, with the majority saying they would continue to vape.

More and more people are switching to vaping devices, but they also report increasing concerns about their health, according to the report.
Among those surveyed, 55% said they felt they were having fewer bad effects than before they switched to e-cigs.
However, the survey also found a significant drop in the proportion of smokers who had never used a tobacco product before they tried e-cig products, from 30% in 2014 to 16% in 2015.
The number of people reporting they were using e-cigarette products to quit smoking dropped from 26% to 16%, while the proportion who were trying to quit using tobacco products also dropped from 15% to 9%.
The survey found that only 13% of respondents said they were smoking regularly.
E-cigarettes, which are sold in a range of flavours and nicotine levels, were introduced in Britain in the late 1990s to reduce the risk of smoking among teenagers.
But many of the devices contain nicotine and have become popular among teenagers, prompting concerns that the products may be addictive and cause problems in young people.
More than 50,000 people in the UK have tried e, and almost one in four are smokers.
