This is a difficult area. On the one hand, I think we all agree that vaping is much better than smoking, so we are trying to get the message out to people to stop smoking and use vaping if need be. At the same time, we do not want vaping to be a gateway, as she says. Giving those mixed messages is never an easy thing to do, which is why we must consider as part of the Khan review the best way to get that message out. The recent Cochrane review shows that vaping is as safe as all other methods of stopping smoking, such as patches, so it should be our key way of stopping smoking.
