I thank the hon. Lady for giving way. She makes a strong argument but, on the other hand, Cancer Research says that there is no comparison between passive vaping and passive smoking. I know many former heavy smokers who have given up smoking and now vape, and that is one of the reasons why I am such an ardent supporter of vaping as opposed to smoking. It is awful for those people to have to go outside and stand with smokers. If people are not allowed to vape indoors, there should be a separate area for vapers. Does she not agree that such a situation sends out the message that vaping is dangerous when we need heavy smokers to give up smoking, and vaping is the best way for many of them to do that?
