Vapers trying to quit cigarettes should not be made to use smoking shelters, MPs have heard. Organisations should consider having a separate vaping room or area instead, a debate on the science and technology committee's e-cigarettes report heard. Putting vapers and smokers together had been likened to "an alcoholic being put in a pub situation and expected to refrain", SNP MP Carol Monaghan said. About 2.9 million people in the UK are currently using e-cigarettes. It is estimated that 470,000 people are using them as an aid to stop smoking.
